Thanks for the input everyone. We had also suspected pad design, but wanted to get input from other sources. The design engineer has implemented revised pad design in a revision set for production next week. Thanks again, Gary M

I just encountered a BGA design were in, underneath the BGA is a silkscreen that covered the entire bottom of the component except for the copper pads. Can you give any information and advice for this type of design.

I designed 0.5mm through hole, and 1.5mm the pad in my PCB, but the manufacturer told me they want to increase the cost because it is difficult to fabricate. But i think my design is correct. Any advice?

Rob, Absolutely agree. Customer precedes standard. As you mentioned design engineers, I think that PCB design has the biggest influence on the voiding. Everything else we do is trying to fix bad PCB design.

If you prefer study PCB design by yourself, I recommend you study on simple circuits first, then try to design simple circuits.

lerning pcb design, you need to know about pcb design software. It maybe take some long time if to be professionals. In fact, you also can contact the pcb manufacturer who have engineering service and provide technological solution. Such as http://ww
