Product Feature And Application

When we mention blind hole and buried hole, the min hole size is usually 4mil or 3mil, which can't be produced with machinery, but made by laser. The hole structure is L1-L2,L5-L6, L2-5L, which is a common structure, relatively speaking. The min line width and space are both 3mil, which need high precision of equipment. Its usage is Banking USB Key. This board has impedance matching, maybe you see its size is small. It use blue solder mask and white silkcreen.


FAQ

● Q: What is the lead time?

A: It takes 1-3 working days for sample, 7-10 working days for batch production based on files and quantity.

● Q:What files do you use in PCB fabrication?

A: Gerber, pcb. Auto CAD

● Q: Can you manufacture my PCBs from a picture file?

A: No, we cannot accept BMP, GIF, TIFF, or JPG pictures as the manufacturing file as these formats are not good for PCB manufacturing. But you can use these files to request a quotation. If you do not have gerber file, you can send us sample to copy it.
