Edge Plating/Half-hole PCB
Half hole pcb: The walls of the PTH holes on the PCB are plated with Half-hole formed by smooth and complete metal forming.The Half hole process on the edge of the board is already a mature process in PCBSKY PCB manufacturing processing.
How to control the quality of the product after forming the Half-hole on the edge of the board. For example, the copper spurs of the hole wall and the residue have always been a problem in the processing.
This type of board has a row of half hole in the PCB, which is characterized by a relatively small aperture, mostly used on the carrier board, as a daughter board of the motherboard, through the half-hole and the motherboard and components The feet are welded together.
Therefore, if there are copper thorns remaining in these half-hole, the soldering of the plug-in manufacturers will result in inaccurate solder joints and weak soldering, which will cause a bridge short circuit between the two pins.
Half hole pcbhas a minimum processing capacity of 0.4 mm for the sample and a minimum of 0.5 mm for the batch.
