Hi C.K. , You can ask your PCB manufacturer to cover all vias with solder mask from CS (It called "pluged" vias). It's done from one side to prevent any close area that can cause "eraption" of solder because of pressure under reflow. All our boards

Does anyone know the current cost to repair a defective solder joint? I seem to recall a number quoted a few years ago of $1.03 per joint with burden of overhead. I've also seen numbers from 50 cents to 50 dollars per joint.

I am having a problem with the green solder mask flaking off exposing bare copper. The mask was defective from the board manufacturer. My problem is the boards are already assembled and we are just finding the problem. Is there a standard that cover

The Cpk collected by placement on glass boards and calibration has been done. All has been fine until we actually try on actual boards with printing. We have problems like insufficient solder due to closed aperture, improper flow of solder on the pad
