4 layer pcb design rules FAQ
Q: What is the MOQ?
A: The minimum order quantity of circuit board is 5pcs.
Q: What the package of the products?
A: We use vacuum packaging.
Q: Do you accept PCB design with different boards on the same panel?
A: Of course, we can do different boards on the same panel.
Q:How do you control the multilayer PCB quality?
A: All boards must pass the test equipment and provide test reports. Sometimes the quick turn service boards don’t have the report. If need it please contact your sales, they will send to you.
Q:What does your quoted price for pcb boards include?
A:The pcb pricing includes board cost (unit price*qty), setup cost, electrical test cost. There are two kinds of electrical test methods, one is flying probe etest, the other is fixture etest. You can choose the suitable method according to order size, repeat orders frequency.
Less 0.2sq/meter the sample include flying test.
