PCI Express: Is 85 Ohms Really Needed?

7 月 28, 2023 通过 admin 0 评论 ,

Just adding my opinions on this subject based on 20 years of SI work.

100 Ohms was usually a target impedance for most differential signaling (PCIX, SAS, SATA, and a bunch of others.) It made sense to have 2 50-Ohm traces (50 was a good round number for most VNAs, too.

I believe Intel came up with the 85 Ohms target (about 20 years ago) for 2 main reasons.

1. 100 Ohms was had to achieve on PCBs at that time since trace widths were greater than 6 mils usually. To get to 100 Ohms, we used to have to void GND planes under traces to use a secondary GND further away.

2. If you built a receiver with 2 50-Ohm resistors in series (to get your 100 Ohms), you would usually have at least 5 to 10 picoFarads of die capacitance in parallel to each 50 Ohm resistance, which would look closer to 37 to 38 Ohms at the rise times of the new Gbps signals. So, they figured that 85 Ohms would be a better match to the traces.

So, 85 Ohms became the PCIe standard – but it is not that relevant today with smaller die capacitances and 3 mil traces.

As the article states, the loss at 85 Ohms is usually greater than the loss at 100 Ohms for the PCB too, not just the cabling. But that has changed with low-loss dielectrics they didn’t have in 2000 for most commercial PCBs. Yeah, there were exotic materials (Teflon), but only special needs for microwave and military applications could afford to use them.

Add to that HVM (High Volume Manufacturing) of traces on PCBs have historically produced tighter tolerances for 85 rather than 100 Ohms, and sometimes it is better to be consistent (match those impedances) in your design than to achieve an ideal value.

93 Ohms comes about because connectors are difficult to design to get down to 85 Ohms, a mid-target of 93 also allows the connector to be dual-purpose for both 85 and 100 Ohm systems, reducing the cost of making 2 different versions.

It is tempting to select cable impedance to match what is used on the PCB. However there are a couple of anecdotal considerations. First, higher frequency reflections are a greater function of the mating connector impedance than the PCB itself. If an incoming signal experiences an increase from 85 on PCB up to 93 ohms for a given connector, it is best to remain at 93 ohm and not create new reflections by following it with a decrease to 85 ohm cable

Secondly, the relationship between impedance and loss is inverse of the PCB relationship. That is, higher impedance cable has less insertion loss whereas higher impedance PCB would otherwise be more loss. The loss difference between 85 and 100 ohms is as much as 14%, and is explained in the actual geometry of the twinax. This is the experience for Samtec twinax eyespeed cable and may not be the experience for all cable suppliers. 

Ultimately, cable impedance choice depends on the priorities for your system. If insertion loss is the greatest constraint, then 93 or 100 ohm cable is the best choice.

IDC or Crimp? May The Best Connector Win.

7 月 28, 2023 通过 admin 0 评论 ,

IDC or Crimp? When discussing options for cable assemblies, designers frequently ask if we recommend discrete wire cable assemblies with crimped contacts or insulation displacement connectors (IDC) with ribbon cable. Our answer is it depends on your application. Crimped connectors and IDC are both reliable connector systems and each has its own list of advantages and disadvantages.

“An insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor(s) of an insulated cable by a connection process which forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the conductors of insulation before connecting. When properly made, the connector blade cold-welds to the conductor, making a theoretically reliable gas-tight connection.”

DC cable assemblies are available on 1.27 mm pitch, 2.00 mm pitch, and 2.54 mm pitch. Most are double-row connectors, but a few are single row.

“Crimped connectors are a type of solderless connection, using mechanical friction and uniform deformation to secure a connector to a pre-stripped wire (usually stranded). Crimping is used in splice connectors, crimped multipin plugs and sockets, and crimped coaxial connectors. Crimping usually requires a specialised crimping tool …”

Discrete wire connectors come in a variety of centerlines, sizes, shapes, and wiring configurations.

Insulation Displacement Connectors (IDC)

IDC’s are quicker, and therefore less expensive, to manufacture. Literally dozens wires and contacts can be terminated at one time.

The insulation on the wires does not have to be stripped prior to termination, or soldered, or individually crimped. This saves a lot of time and therefore money.

Most IDC’s can be terminated by a basic hand press or other simple tool.  For that matter, generally, much lower forces are required to terminate the ribbon cable to the IDC contacts.

IDC has been around since the 1950’s and is an accepted connector design. It’s so accepted that connector companies offer a large variety of design and manufacturing options. They are available in a variety of wire gauges, pin sizes and centerlines. Mating connectors for the IDC cable assembly incorporate options to increase the ruggedness of the assembly with features like locking clips, ejection latches, strain relief, and polarization, to name just a few.

Assuming you are purchasing your components from a reputable connector supplier (like Samtec!), IDC’s are gas-tight and vibration-proof because of the quality of the design and manufacture of the contacts and plastic insulators which house them.

In the assembly process the metal blades penetrate any surface oxides on the wire.

In our opinion one of the biggest disadvantages of ribbon cable and IDC is the cable is relatively inflexible and stiff, and the cable pretty much has to travel from one point of termination to another in a relatively straight line, or with minimal bends and angles.

Crimped Connectors (Discrete Wire)

Because cable assemblies with crimped connectors almost always incorporate discrete (individual) wires and not ribbon cable, these crimp cable assemblies can fit into some tight areas that ribbon cable can’t. They can bend, angle, and flex into some tight bends and small nooks and crannies. As mentioned previously, IDC cable assemblies pretty much have to go straight ahead and can’t bend. 

Discrete wire assemblies can break-out from a higher pin count connector to several smaller position connectors. You can also do this with IDC, but you have more flexibility and options with crimped connectors.

We frequently pull pins between — in other words, selectively populate — the plastic insulator to meet creepage and clearance requirements.

Like IDC, crimped contact systems are available in a large variety of design and manufacturing options:  a variety of wire gauges, pin sizes, centerlines, latches, and options to increase the ruggedness of the system.

The biggest disadvantage is cost, primarily in assembly and manufacturing time, and tooling and assembly can be more complex.

I’m sure if I thought longer I would come up with more differences between these two systems, but I think we’ve covered the main points.

5G connector to help 5G communication realize vision

7 月 27, 2023 通过 admin 0 评论 ,

In 2019, 5G communication began commercial deployment globally. So, what led us to have made such a revolutionary transformation in the field of communication? The smooth realization of 5G communication is inseparable from 5G chip manufacturers, OEM manufacturers, communication agreement standard formulation agencies, and many companies. 5G communication has gone from scientific research to formal commercial use. Along the way, I also experienced many failures, and finally successfully achieved commercial use, so as to change the world.

The connector is usually an electronic component that is easily overlooked. The connector does not play the core function like the LTE or WiFi transceiver, but it is indeed an important basic component. The connector assumes the signal transmission function. In this process, the minimum implementation of the attenuation and distortion in transmission is our ideal.

From the Wi-Fi, which is ubiquitous in the Moson password and telegram, to the honeycomb communication, and the ubiquitous Wi-Fi in our daily life, the connector plays a very important role in communication. In recent years, the connectors in the consumer electronics field have always focused on a theme such as miniaturization, trying to solve complexity and various problems.

Among the connector products developed by I-PEX, from the MHF®i to the MHF®5 series of microbenic coaxial connectors, from the perspective of size, the area and chimeric height have steadily decreased. Features, such as: Bobby and insertion losses have improved to some extent. However, with the requirements of new technologies for connectors, this model has become unreasonable. 5G communication requires us to do more than before.

At the same time of 5G communication requirements, the connector needs to improve the S parameter (resident wave ratio and insertion loss), and it is also necessary to increase the shielding effect of the connector and wiring beam in the chimeric state. Only in this way can we reduce electromagnetic interference and improve the electromagnetic compatibility performance of the whole machine.

The II-PEX company is a pioneer for developing and producing 5G millimeter waves and Sub 6GHz with coaxial types and board-to-board connectors. The product has also been applied to early 5G communication devices. These devices include: smartphones, laptops, mobile hotspots, AR/VR, and wireless access devices in fixed positions.

Novastack® 35-HDN connector

The NOVASTACK 35-HDN series connector is the best choice for electronic products with high space restrictions such as smartphones and hotspots, which can transmit a 15GHz band of the mid-frequency IF from millimeter wave frequency. The product spacing is 0.35mm and a chimeric height of 0.7mm is a super small design, which enables R & D engineers to flexibly cloth and maximize the use of space. The application of patented technology-360-degree shielding can cut electromagnetic interference to the greatest extent after the connector is chimp. Due to the restrictions of the overall space, such as smartphones, mobile hotspots, miniaturization and excellent shielding, are a huge challenge for R & D engineers.

MHF® 7s connector

The MHF 7S series polar shaft connector reflects the huge breakthrough of stamping technology in the production of miniaturized connectors. The MHF 7S series connectors redefine the boundary line that can be done, and is in the leading position of anti -electromagnetic interference. Revolutionary design can eliminate the main sources of electromagnetic interference. As electronic products are full of numerous radio frequency signals, this design can effectively reduce interference, thereby helping manufacturers can successfully pass electromagnetic radiation testing. In addition to reducing electromagnetic interference, the MHF 7S series connector is 1.5mAX at 15GHz, the packaging size is 2.0mmX2.0mm, and the chimeric height is 1.4mm. This connector is superior to the electromagnetic interference performance. It is an ideal choice for the ground frequency band (15GHz) transmission equipment, including: small base stations, laptops, wireless access devices, CPE, etc.

EMC Shielding Connectors

7 月 27, 2023 通过 admin 0 评论 ,
  1. PEX manufacturers connectors for a wide variety of equipment applications. We will discuss our “EMC Shielding Connectors” in this webinar.

When electromagnetic noise generated inside or outside the device interfere with the circuit inside the electronic device, creating (noise, unnecessary current may be induced to the circuits in the devices causing a malfunction or damage to high-performance electronic components which may also lead to  device failure. Therefore, effective countermeasures against electromagnetic noise must be taken, especially in high-performance compact electronic equipment with high-density electronic components.
There are two types of interference-conduction paths for electromagnetic noise: “Conducted Interference” and “Radiated Interference”.

For conducted interference electromagnetic noise, which is transmitted through conductors such as cables and board traces in equipment, the interference noise can be isolated and adjusted by incorporating electromagnetic noise filter components into the circuit appropriately. 

On the other hand, for radiated interference electromagnetic noise, in which electromagnetic waves are radiated as noise into a space and conducted to another circuit, it is necessary to take measures to block noise conduction in the air by using shielding. 

However, if the board circuitry, including the internal connectors that connect modules, is covered with shields, it may be difficult to unmate the connectors when necessary, for example, when repairing equipment . In this case, the use of a high-performance EMC connector, which prevents electromagnetic noise in the connector itself, can provide EMC countermeasures for the connector part without sacrificing the connector mating/unmating function.

ZenShield® Connectors

ZenShield® , I-PEX’s high-performance EMC shielding connector series, offers various types of EMC shielding connectors for different applications, including micro-coaxial,  micro RF , board-to-board FPC , and FPC/FFC connectors.

The ZenShield® connector series provides 360-degree EMC shielding to prevent electromagnetic noise radiation not only from the contact points of the plug and receptacle, but also from the board mounting part (SMT positions) of the signal terminals. In addition, the shields of both the plug and receptacle are properly grounded at multiple points when the connectors are mated, and are also properly grounded at multiple points on the board. This design protects the signal in the connector from external electromagnetic noise and prevents the signal in the connector from radiating electromagnetic noise to the outside. This unique shielding design provides the I-PEX ZenShield® connector series with excellent EMC countermeasures. 

The effect of the EMC shielding is shown more clearly in this electromagnetic interference (EMI) simulation, comparing a general connector with a ZenShield® EMC shielding connector. The left figure shows a cross-sectional view of a general, partially-shielded micro-coaxial connector, and the right figure shows a ZenShield® EMC shielding connector, CABLINE®-CA II.

The leakage from the signals is displayed in light blue.
In the general connector, on the left, leakage from the signals emanates out from the connector through the contact tail areas. In the ZenShield® EMC shielding connector, on the right, the radiation from the signal pin is restricted to the area within the connector and its shield. Outside of the connector, there is almost no light blue emissions.

Because the connector itself can significantly reduce EMI due to this design, ZenShield® allows for a flexible board design, such as placing the connector close to the antenna, especially in high-performance electronic equipment with wireless communication functions that are required to address intra-system EMC issues.

With these design features, the connector itself provides significant mitigation of EMI. ZenShield® gives board designers more flexibility for designing the board by allowing the connectors to be placed in close proximity to sensitive subsystems, such as transmit/receive antennas, that are commonly found in high-performance wireless communication systems.

The ultra-fine coaxial cable assembly offers stable mechanical structure and supports high-speed signal transmission. With the high flexibility and shielding properties of the ultra-fine coaxial cable assembly, it is highly suitable for electronic products requiring high-capacity data transmission.

Structure of coaxial cable:

Coaxial cable is a multi-layered structure, consisting of a center conductor, insulation layer, outer conductor, and outer covering, known as the ‘coaxial cable’.

Ultra-fine coaxial cable

In coaxial cables, the cables used for high-performance small devices such as laptops, foldable smartphones, and medical equipment are extremely small. Generally, coaxial cables with an outer diameter ≤1mm are referred to as “ultra-fine coaxial cables”

High Flexibility

Ultra-fine coaxial cables are commonly used due to their higher flexibility compared to shielded FPC/FFC. They can maintain stable electrical characteristics even when bent

Excellent Impedance Control

When a high-speed signal is transmitted through a cable, the electrical signal can reflect at impedance discontinuities. Therefore, it is necessary to maintain a constant impedance as much as possible to suppress interference and ensure signal quality. By adjusting the distance between the center conductor and the outer conductor or the insulating material, the impedance of the ultra-fine coaxial cable can be appropriately controlled

Outstanding Shielding Capability

The outer conductor of the ultra-fine coaxial cable serves as electromagnetic shielding, providing excellent resistance to electromagnetic interference (EMI) by preventing the leakage of electromagnetic noise from the signal transmitted through the center conductor. Additionally, it exhibits good immunity to electromagnetic susceptibility (EMS) by effectively protecting against external electromagnetic noise

Ultra-fine Coaxial Cable Assembly Process

By terminating the ultra-fine coaxial cable with connectors, it is possible to create small and flexible assemblies of ultra-fine coaxial cables with excellent electrical characteristics

High-Performance Electromagnetic Compatibility Shielding

By using I-PEX’s EMC shielded connectors (ZenShield®), ultra-fine coaxial cable assemblies can provide significant electromagnetic interference mitigation. Therefore, ultra-fine coaxial cable assemblies with ZenShield® connector series are commonly used in high-performance electronic devices equipped with wireless communication capabilities, which require addressing EMC issues within the system.

Product Assembly Process with High Flexibility Advantage

The flexible cable characteristics of the ultra-fine coaxial cable assembly allow it to be used in various application scenarios, such as situations where the cable needs to pass through rotating components or in narrow and complex structures that make wiring challenging during assembly

Suitable Application Examples

The benefits and advantages of ultra-fine coaxial cable assemblies lie in their capabilities for mechanical and signal transmission. These components can handle high data rates while providing a high degree of flexibility and shielding performance.

Below are application examples that demonstrate the flexibility of ultra-fine coaxial cable assemblies

Why do connector terminals need plating? Mainly for these four reasons:

7 月 25, 2023 通过 admin 0 评论 ,

Connector terminals are an indispensable part of electronic devices, serving to connect electronic components on circuit boards. The production of connector terminals involves multiple processes, with electroplating being a critical step. So, why do connector terminals require plating?

Firstly, plating helps prevent corrosion of connector terminals. Connector terminals are usually made of metal, which is susceptible to oxidation, corrosion, and other factors. Without electroplating treatment, the connector terminals can experience corrosion during use, leading to poor connections, signal interference, and other issues. Through electroplating, a protective film is formed on the surface of the connector terminals, effectively preventing corrosion.

Additionally, electroplating enhances the conductivity of connector terminals. The conductivity of connector terminals is crucial as it directly impacts the performance of electronic devices. Through electroplating, a conductive layer is formed on the surface of the connector terminals, improving their conductivity and ensuring the proper functioning of electronic devices.

Furthermore, plating also strengthens the adhesion of connector terminals. Connector terminals need to establish a secure connection with components on the circuit board. If the adhesion of the connector terminals is weak, issues like looseness and poor contact can occur. Electroplating creates a strong adhesion layer on the surface of the connector terminals, effectively enhancing their attachment and ensuring reliable connections.

Lastly, plating enhances the aesthetic appearance of connector terminals. Connector terminals are often exposed, and surface imperfections such as roughness and oxidation spots can affect the overall aesthetics of the electronic device. Through electroplating, a smooth and uniform surface layer is formed on the connector terminals, improving their visual appeal.

In summary, connector terminals require electroplating primarily for corrosion prevention, improved conductivity, enhanced adhesion, and aesthetic purposes. Electroplating is a crucial step in the production of connector terminals as it effectively enhances their performance, reliability, and ensures the proper functioning of electronic devices.

The lock function of the connector

7 月 24, 2023 通过 admin 0 评论 , ,

Connectors with locking functions can strengthen the mating retention force, which helps prevent disengagement of the connection. There are various types of locking methods for connectors.

With the development of high -performance and miniaturization of electronic devices, portable consumer devices such as personal computers, tablets and smartphones have become a well -known thing in our daily life. We take them wherever we go. However, the more frequent the number of portable equipment we carry, the greater the risk of accidents. Therefore, the cables and connectors used for mobile devices should have anti -impact and vibration resistance.

Connectors with locking function can enhance the sustainability of chimeric and prevent connection interruption. The connector has various types of locking methods.

1. Cabline® series lock function

A variety of extremely fine coaxial connectors in the Cabline® series have a lock function

For example, Cabline®-VS II is a 0.5 mm spacing horizontal plug-in model. In the chimeric steps, first complete the chimeric of the public seat, and then rotate the lock cover on the public seat to the parent seat on the PCB.

Maintenance data

For example, the comparison results of Cabline®-VS II 30P public seat show that the public seat with locks remains about 8 times without locks.

* I-PEX can also evaluate vibration, impact, drop test, etc. based on the conditions of the customer’s use

Cabline®-UM is a low-back vertical insertion connector with a 0.4 mm spacing. It has a unique lock cover structure and can achieve automatic locking.

2. MHF® series lock function

MHF® small radio frequency coaxial coaxial connector series has an LK type and has a lock function. Its patented mechanical locking characteristics have greatly improved the maintenance of the public seat compared with similar small radio frequency coaxial connectors in the market. 

Maintenance data

For example, the public seat maintenance comparison of the MHF®i series connector shows that the MHF®i connector with a lock -locking holder (MHF®I LK) is about twice the MHF®i connector without mechanical lock functions.

MHF® connector series with locking function

3. The lock function of theevaflex® series

EVAFLEX® FFC/FPC connector has an automatic locking function, which can realize a one -step chimeric FFC/FPC, which is stronger and durable than the traditional FFC/FPC connector. Its one -step operation also helps to increase productivity, and it is also designed for the automation of robots.

When the FPC / FFC with a gap is inserted, the Lock Pin with flexible rail shapes in the EVAFLEX® series connector will be locked. In addition, clicking real -time feedback will help prevent situations without completely chimi. The automatic lock structure is reliable to fix the FFC position with gap to create excellent maintenance to fight against tensile and vibration.

FPC maintenance data

For example, EVAFLEX® 5-HD 24P connectors, FPC’s maintenance comparison results show that the FPC with locks remains about 3 times without locks.

EVAFLEX® Connector Series with Auto-Locking Functions

4. The lock function of miniflex®

Miniflex®FPC / FFC connector is usually called Zifs or Lifs, and there is also an LK type with mechanical lock options.

The contact point of the lock generates high maintenance. These contact points are located on both sides of the connector and are designed to capture and maintain a specific incision area of the FPC. They need higher FPC maintenance, and to increase the ideal solution to the smaller PIN count to increase FPC.

FPC maintenance data

For example, the miniflex® 3-BFN series, 0.3 mm spacing, horizontal chimeric FPC/FFC connector, 19P FPC guarantee comparison results show that the maintenance of the LK type FPC lock is better than a connector without lock locks. Keep a height of about 1.7 times.
