The pad size will be enlarged by 0.5mm than the hole size. The annular ring size will be enlarged to 0.15mm in production. for the 0.6mm hole size, the finished hole size between 0.52mm to 0.73mm is acceptable.Ĭurrently we don't support Blind/Buried Vias, only make through holes.įor Single&Double Layer PCB, the minimum via hole size is 0.3mm For Multi Layer PCB, the minimum via hole size is 0.2mmįor Single&Double Layer PCB, the minimum Via diameter is 0.5mm For Multi Layer PCB, the minimum via diameter is 0.45mm(Limitation 0.4mm). For the 0.8mm board thickness, the finished board thickness ranges from 0.7mm(T-0.1) to 0.9mm(T+0.1).įinished copper weight of outer layer is 1oz or 2oz.įinished copper weight of inner layer is 0.5oz by default.Ģ oz inner copper weight is available for 4-layer PCBs with 1.6mm thickness/JLC2313 stackup/2oz outer copper weight. For the 1.6mm board thickness, the finished board thickness ranges from 1.44mm(T-1.6×10%) to 1.76mm(T+1.6×10%)Į.g. ☐.2mm for CNC routing, and ☐.4mm for V-scoringĮ.g.
