We're running into problems with board damage (broken traces, solder shorts) due to pliers and other bizarre tools being used for depanelization. I need some sort of fixture for this. A delrin plate with a slot cut to the correct depth and width migh

Some people involved in PCB assembly process claim that SMD components reflow soldering problems are often caused by traces running under a component. According to this claim, trace (or any copper) covered by solder mask and placed under SMD componen

Dream: Yes, VIA's are connected to actual SMD pads via traces - roughly .030" from the pad. The VIA is .013" in diameter, and the excess solder bleeds out of the actual VIA barrel after the 1st reflow.... -CK

Hello. We are a contract manufacturer that requires the removal of the green making layer on a PCB board. What we need to do is expose some of the conductive trace (estimated .025 length) to create a solder joint to a SMD. It sounds ridiculous, bu

Hello every one! I need help with a misaligned theta at plcc44, the machine is a IP3 smd3, firmware 2.99, vision card 4400 and both camera type YD2048N on label but in Proper data is set 2 (I don't know if this is right) we use Fuji flexa, Back Lig

I'm looking for some SMD shims or something to solve this problem. We have a coin cell on a PCB and the side that contacts the PCB also has traces under the cell that don't connect to the cell. So I'm after some small dots of something suitable for

The impact is low on larger pitches and pad sizes. as things get to the .4mm pitch the pad differences start affect your ball size and yields. The trace size going into the pads and the solder mask relief can cause some odd shaped pads with signif
