With the rapid development of connector applications such as pin headers and socket headers, the introduction and upgrade of the economic and technological processes of connector products have fueled intense market competition in the connector market. As the landscape shifts from imported to traded to locally manufactured products, the prices of socket headers have gradually become more favorable. The rapid development of market competition in the production and manufacturing industry also drives technological innovation and cost reduction among Chinese socket header manufacturers. Analysis indicates that all pin headers, socket headers, and connector markets currently face two levels of market competition. Firstly, there is the threat from substitutes, with wire terminal strips being a key alternative to connectors. Although the threat in the high-end Chinese market is not particularly significant, it is experiencing fierce competition in the mid-to-low-end market. Under the pressure of cost, suppliers often opt to substitute connectors with wire terminal strips that are currently more cost-effective.

Under the condition of static electricity prevention, the installation and manufacturing processing factory using plug-in connectors should have a good static electricity prevention strategy.

Secondly, the temperature and time for wave soldering machines during the pin connector assembly must be strictly controlled. The heating temperature should be 100℃±5℃ and not exceed 120℃, with a stable temperature increase, and the soldering temperature should be 245℃±5℃, with the soldering time recommended not to exceed 3 seconds.

In the thermal dissipation design, the heat sink connector generates heat during operation, which leads to excessive temperatures. Consequently, both the thermal dissipation design of the PCB material and the air circulation thermal dissipation design of the housing can harm the main performance of LED products.

In the design scheme, the allowable current for the current pin header connector is 50mA. It is generally recommended that the applied current not exceed 80% of the allowable current value, especially for displays with small pitch spacing, due to the heat dissipation standard deviation, where the current should be reduced.

In terms of controlling the flatness of the light, for direct pin headers and female connectors, there should be adequate production processes in place during the baking process to ensure the LEDs are vertically evenly distributed on the PCB board.
