Warm prompt:

1, all the sample pictures as appearance and technology reference only, we are custom manufacturing enterprises, there is no spot. Production need to provide PCB design line data,

Process requirement or sample product customization.

2, when the order confirmation to arrange production, due to the irreversibility of PCB production, will not do it again modification. So please order file, be sure to check good PCB has no error!

3, our project before production if there are some problems will contact you in time, please keep clear of your mobile phone or telephone, so that you can communicate with you in time.
