for the 1.00mm Plated hole, the finished hole size between 0.92mm to 1.13mm is acceptable.Į.g. The minimum diameter of castellated holes is 0.60mm.Į.g. The minimum Non-Plated Slot Width is 1.0mm, please draw the slot outline in the mechanical layer(GML or GKO) The minimum plated slot width is 0.5mm, which is drawn with a pad. (there will be no copper dig out optimization for single board). We make NPTH via dry sealing film process, if customer would like a NPTH but around with pad/copper, our engineer will dig out around pad/copper about 0.2mm-0.25mm, otherwise the metal potion will be flowed into the hole and it becomes a PTH. The minimum NPTH dimension is 0.50mm, Please add the NPTH in the mechanical layer or keep out layer. If the recommended sizes are not respected then the pad will not be produced properly. The minimum size of annular ring around plated through hole pads is 0.25mm. 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.
