How should row needle be used just better? These five points are prepared for you. I hope they can be helpful to you. The following details:

1, heat dissipation design Pin and busbar will heat up when working, too high temperature will affect the attenuation speed and stability of LED, so the heat dissipation of PCB board and the ventilation and heat dissipation of box will affect pin and busbar.

2. Check whether the antistatic pin and busbar have good antistatic measures.

3. The current value of the pin and bus is 20mA, and it is generally recommended that the upper limit of the current is not more than 80% of the nominal value. Especially for the electronic equipment with very small point spacing, the current value should also be reduced due to poor heat dissipation conditions.

4. Control the verticality of the board. For the straight-inserted pin and bus, sufficient technology should be available to ensure that the LED is perpendicular to the PCB board when passing through the furnace.

5. The temperature and time of wave soldering shall be strictly controlled. The preheating temperature is 100 ° C ±5 ° C and the upper limit does not exceed 120 ° C. The preheating temperature must rise steadily. The welding temperature is 245 ° C ±5 ° C.

Generally speaking, we need to pay attention to these five points after the purchase of needle and mother row, which will avoid many problems affecting the performance of needle and mother row. There are five things users can do to circumvent it.
