Some friend of mine has recommended Yanxia for me to review my manufactured PCBs before sending it so I can save money and time cause he's Chinese that gave him an advantage as JLCPCB factory is there and that will be much better like one stop shop for all PCB services. I 've found him very helpful and delivered exactly on the time. thanks Yanxia.
