Any one got experience on handling solder bridging under one corner of BGA?

Hi Researchmfg, If upload picture would be great to interpret this question, anyway,if bridge occur defect should be adjudge NG product,to avoide this issue,firstly,bridge is a PCB defect that happens when solder gets to an area it shouldn't be. You

Hi guy Please help advise me the impact of using Nitrogen to solder bridging defect. I heard somebody said that using nitrogen can effect the bridging problem by higher surface tension in case inaccurate printing . Is it true? Thanks.

I may be wrong, but I'm thinking that nitrogen has less effect on solder bridging as does the amount of solder that is present. Nitrogen allows better wetting becasue there are no oxidation effects. If you have solder bridging problems, look at the

A bridge is a defect. Full stop. If you are working in contract manufacturing, talk to the customer and get approval from them to accept it. They will not refuse unless there are high risks involved. If you are building your own products, then have

Does the bridge/short defect is consistent? If bridge is not consistent then QA guy and customer will think it is a defect even its adjacent pads are electronic connected.

Caleb, If the leads were connected via trace, and this would be accepted by the customer, production documentation must be updated with the deviation. What people see is a bridge, 95% of them don't look further if the bridge is on a common trace o

Calebc, My opioin is different. If the bridge is consistent then we can treat it as the design made it. If the bridge is not consistent then QA and Process engineer shall take a look since the process is not stable.

Hello once again! I am having a problem with a 24 pin connector bridging on the wave. We use very similar connectors on other PCB with zero problems. This connector bridges in the same place on the same pins. It forms like a little block of four

There are several things that can be done. Shortening the lead length should eliminate bridging between lead. We had done a project several years ago where the customer had shortened the leads to almost flush to the board, preventing any chance of
