If you need to know the exact copper thickness of the board, you can ask the Fab to offer the microscopic report, I have already made a 2oz board in ALLPCB before and asked them offeed me this report,usually normal factories can offer it but need add

I ordered 100boards from one China PCB prototype manufacturer,but there was appeared inner short. How can this happen when boards are electrically tested? And how to avoid this?

how many parts are you looking for? Certain sizes of SMT? You said you have boards, so you'll need parts that fit the pad layouts of those boards. Also, where are you located?

Thanks for info regarding rotating probe head. We do not recommending to use this probes as it may damage bare board as it will pierce thru board and will shorted etches.. Avoid using this probe for PWBA

Typically, the reliability of PCBs suffers significantly due to the increase in aspect ratio. It is not preferred to opt for high thickness boards. However, I would like to point out that your assumption seems to be wrong as board layers do not direc

While I agree there is "too much solder" on this board, I don't think that is the sole explanation of what's going on here. I don't think the pads on the board match up well with the terminations on the components.

I don't work with AOI's but it sounds like you just scratch the surface if you evaluate only with good board and bad board.

Hi,I am a newone here.I wonder if the copper strip can be tin welded on PCB board?How should it be welded?Are there any requirements?Are there any defects?

The chip resistors are placed on the edge of the board, but the board has no or enough waste tabs. When de-panelizing, the bits may contact and break them. You can use a smt carrier, or add waste tabs in your next assembly manufacturing.

I did some research and got the Y board part number and have it on order. The entire board ,not that part. Thanks.
