LED aluminum boards are 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.
