What SWAG said. We use a PCB Router exclusively for rigid flex assemblies. On a side note, we have begun to save fixturing costs by using 3D print technology to produce many of the fixtures, for both rigid and rigid flex. We can design and print l

Hello. Thank you for your answer. Yes, you are right. It would be best to badmark those boards. But we, as a small contract assembler, can't throw away a 1/5 of client boards just because of damaged fiducials. Using pads and other features as fiducia

Looks like you have bad wetting. I will do in this order as it is easier to troubleshoot starting with the machine and transitioning to the PCB: 1. First clean some bare PCBs really good and try again. 2. Check thermal profile 3. Check flux - amount

Pin holes in the gold can allow for corrosion of the underlying nickel and copper to form copper and nickel oxides on the gold surface (example - http://www.semlab.com/blog/?p=564. The corrosion can work itself all the way through the EN layer (exam

I found that some guys in the forum will raise a question and answer the question by themself, just intend to attract others attention, and then sell their products. There's nothing wrong with selling your product, but if you intend to promote your p
