What are the advantages of pin header and socket connectors? Precautions for using pin header and socket connectors!

Pin header and socket connectors are widely used in the electronics industry mainly due to their 6 key advantages:

1.Compact design and convenient fitting, with noticeable differences in size and assembly compared to through-hole pin headers.

2.Pin header and socket connectors can attenuate electromagnetic interference and possess the ability to shield against electromagnetic interference.

3.As connectors are typically used as communication interfaces between PCB motherboards and external components, pin header and socket connectors have a strong load-bearing capacity, even under significant external forces.

4.Components assembled using through-hole technology exhibit higher reliability compared to their surface-mount counterparts. Pin header and socket connectors can withstand strong tensile forces, torsion, and thermal shocks without detaching from the PCB.

5.They can meet the requirements for high voltage and large current transmission.

6.Pin headers, contact points, or contact terminals can withstand additional test voltages.

Operating precautions for pin header and socket connectors:

1.Check if anti-static measures are in place for the pin headers and sockets.

2.Strictly control the temperature and time during wave soldering. The preheating temperature should be 100°C ±5°C, not exceeding 120°C. The preheating temperature should rise steadily. The soldering temperature should be 245°C ±5°C. It is recommended to keep the soldering time within 3 seconds.

3.The minimum current value for pin headers and sockets is 20mA. It is generally recommended to use a current not exceeding 80% of the rated value. Particularly for devices with small pin spacing and poor heat dissipation conditions, the current value may decrease.

4.Pin headers and sockets generate heat during operation. Excessive temperature can affect the decay rate and stability of LEDs. Therefore, the heat dissipation of the printed circuit board and the ventilation of the enclosure can both affect the performance of pin headers and sockets.

5.Control the verticality of the circuit board. For straight pin headers and sockets, ensure that LEDs are perpendicular to the printed circuit board during reflow soldering by employing adequate technical measures.

Introduction to I-PEX ISFIT Power Terminals

Solderless press fit connectors are typically used in PCB based assembly processes. Traditional connectors are directly welded to the board, and press fit connectors can be installed using a simple pressing method, thereby simplifying the process. By eliminating the solder installation process, manufacturing costs are reduced.

However, this pressing method can cause damage to the PCB and requires significant insertion force during installation. To address these issues, I-PEX provides a completely new concept of terminals: ISFIT ® series

1.ISFIT ® Reduced damage to PCB

Their unique terminal design and spring structure reduce damage to the PCB during insertion. Traditional fisheye terminals do not have a bullet structure, which can damage the edge of the PCB through-hole and also damage the inner wall.

2.ISFIT ® Only low insertion force is required

ISFIT ® The shrapnel structure terminal absorbs insertion force during the insertion process. Compared to fish eyes, it reduces the coefficient of friction and keeps the insertion force low from start to finish

3.ISFIT ® Terminal series

Why are wiring terminal connectors always plated with a layer of nickel, and what are its characteristics?

In order to protect the terminal contact base material from corrosion, optimize the surface performance of the terminal, and establish and maintain the contact interface between terminals, surface treatment, specifically electroplating, is performed on the terminal connectors. Why is nickel plating chosen for this purpose?

This is because nickel plating offers the following four characteristics:

1.Fine crystalline structure: Nickel plating has excellent polishing properties, resulting in a mirror-like appearance that can maintain its shine over an extended period in the atmosphere.

2. High stability in the air: The nickel layer is highly stable in the air due to the strong passivation ability of metallic nickel. It rapidly forms a thin passivation film on the surface, which protects against corrosion from the atmosphere, alkalis, and certain acids.

3. High hardness: Nickel plating provides improved wear resistance to the product’s surface. It is commonly used in the printing industry to enhance the hardness of lead surfaces. Additionally, in chemical equipment, thicker nickel plating is often employed to prevent corrosion by the medium, benefiting from the high chemical stability of metallic nickel.

4. Wide range of applications: Nickel plating can serve as a protective and decorative coating. It is used on steel, zinc die-castings, aluminum alloys, and copper alloys to protect the substrate from corrosion or for decorative purposes, providing a bright and shiny appearance.

What is a connector? What is the function of a connector?

In our daily lives, connectors are actually used in many places, but you may not be aware of it. Here, I will show you the functions, working principles, and classifications of connectors.

Connectors are electronic components used to connect power and electrical signals. They are commonly referred to as plugs and sockets. Generally, connectors refer to electrical connectors, which are devices used to connect two active components for the transmission of electric current or signals.

Connectors are not only applicable to items closely related to our daily lives, such as smartphones and computers, but also to all electronic-related terminal devices. Since connectors need to accommodate different design styles and purposes, there are various types of connectors available. For example, memory card slots are installed on the PCB of a computer case to connect storage cards. There are also card socket connectors used to connect various cards, such as SD card sockets.

With connectors, both production and maintenance become much more convenient. For instance, directly connecting circuits within a device would take a long time, and dismantling becomes more time-consuming during repair processes. However, with the use of connectors, the process becomes much more convenient. Connectors also facilitate batch production and efficient maintenance.

For the classification of connectors, there is no fixed and unified method. They can be categorized based on their purpose, shape, structure, and performance. Here are a few common classification methods:

1.Shape: Connectors can be classified into five types based on their shape: circular connectors, rectangular connectors, strip connectors, circular arc connectors, and D-shaped connectors. Circular and rectangular connectors are more commonly used.
