Know how to help see my description:
We told our customers that our PCB is used KB6160 B grade material, and then the customer back to the message said "
You are using the KB6160 (FR-4) application of reinforced plate, potentiometer, resistance film field, the lowest level of the kind of plate it!
Is very bad.
KB6160 B grade material is defective.
I guess the landlord may be a PCB company in the south of it KB sheet, tell the truth, in the industry can be considered the worst. I am in the PCB business to do sales, under normal circumstances, even if the customer requires the use of KB sheet, we will find ways to not let them use, because it is sucks, with the day after the guest complaints continue. I have been to KB in Kunshan factory, feeling like the eighties to bankrupt state-owned enterprises, 5S management mess. The proposed landlord for the plate it, with Kingboard plate, it is hit their own signs.
