Your vizit card

Hi.

Do you invest in mailing your card. if so, how to give it up, so it was impossible to determine exactly what you have made printed circuit boards?

Why no response from the administration?

still waiting for an answer…

Perhaps they might reply if they understood the question.
Try asking again, this time in English.

Hi there,
Yes, the PCB manufacturer must print their code on the board, we had contacted with them to discuss about the problem, but they told us the code is necessary for deliver goods.They could print the code on the bottom layer, but remove it is impossible. The code is only some small letters and Arabic numbers.
Sorry for the inconvenience and later reply.
Regards,
Dingding
