Pin row mother row

For example, the most commonly used connector products in the electronic industry, as a manufacturer, how to ensure the quality of the product? In order to ensure the quality of products, what kind of technology should be involved in the production of needle row connectors? The following text mainly explains some technical problems involved in the application of needle row connectors.

1.Designing the nominal current of needle and busbar with current value of 20 mA, it is generally recommended that the maximum current should not exceed 80% of the nominal value. Especially for the display screen with small point spacing, due to poor heat dissipation conditions, the current value should also be reduced.

2. The electronic display screen should control the verticality of the lamp. For the product of the direct-inserted needle row mother connector, there should be enough technology to ensure that the LED is vertical to the PCB board when passing the furnace.

3. For example, in the application of electronic display panel assembly plant to needle row connector products, anti-static measures should be taken.

4. Needle-row and mother-row connectors produce heat when they work, so heat dissipation design should be done well, because too high temperature will affect the decay and stability of the LED, so the heat dissipation design of PCB board and the ventilation and heat dissipation design of the box will affect the performance of the LED.

5. The temperature and time of wave front welding should be strictly controlled. The preheating temperature is 100 +5, the maximum is not more than 120 and the preheating temperature should rise steadily. The welding temperature is 245 +5 and the welding time should not exceed 3 seconds.
