Various lighting and signal devices are installed on the car to ensure the safety and reliable operation of the car. It is used to illuminate the road, indicate the width of the car and the location of the car, and illuminate the interior of the car. Indicating instruments and vehicle maintenance at night. In addition, under turning, braking, meeting, parking, reversing and other working conditions, it should also emit light or sound signals to warn pedestrians and other vehicles.


With the development of electronic products in the direction of [light, thin, short and small", LED aluminum boards are also developing to high density and high difficulty. A large number of SMT and BGA PCBs appear, and customers should be led aluminum substrate manufacturers when mounting components to plug hole, mainly because:
1. Preventing short circuit of tin from the through hole through the component surface during over-wave soldering of the LED aluminum substrate;
2. Avoid flux remaining in the via hole;
3. After the surface mount and component assembly is completed, the PCB is vacuumed on the test machine to form a negative pressure:
4. Prevent the surface solder paste from flowing into the hole to cause solder joints, which affects the placement;
5. Prevent the soldering of the solder balls from over-wave soldering, causing a short circuit.
