We have our PCB factory in China and PCB-Assembly factory in USA, both of them with fully automated production line to meet what you need. We have our cetifications UL, ISO14001, ISO9001 and TS16949.
DITSA keeps 24 hours respond. We make an response whithin 30 minutes if you need us even in weekends while it's emergency. We provide fast board with 24hours, 48hours and 72hours for 1L-4L PCB and PCBA production.
We have our engineers to help to provide you the suggestion on your files or build PCB file, bom list and PCBA file following your requirements. From design your PCB to make the production, we have all-in-one solution.
Quality PCBs. Extraordinary savings. Satisfaction guaranteed.
