PCB Drill Hole, PTH, NPTH

Laser drill and mechanical drill hole contrast:

Hole Φ≦ 0.2 mm	Hole Φ≦ 0.2~0.3 mm	Hole Φ≧ 0.3~6.3 mm	Hole Φ≧ 6.3 mm
Laser process	Sample board (mechanical or laser)	Normal process (mechanical)	Milling process (mechanical)
Sample board prototype High efficiency High Cost	Sample board prototype Low efficiency for mechanical way	Applied to most products: prototype PCB Mass production High efficiency High Quality Low cost	Sample prototype Mass production

DiGPCB's reliable equipment and redundant manufacturing capability, Can adequately protect product quality and service efficiency.

Non-metallic through hole (NPTH),Plated through hole (PTH),Plated pads hole

For stamp hole examples, We recommend using via hole make stamp hole of multi-pcb panel.
If necessary, please use the V-cut proess alternative stamp hole. This reduces the risk of break in shipping.

Long Drill hole (elliptic drill hole)
