We have an AUREL CS1222 machine to measure the thickness of the solder paste deposited on a bare board by a stencil printer. This device has a laser beam that has to be put on the pad where you want to measure the solder paste thickness. The measure

Same idea but simpler execution. Verify Solder pot temperature. Verify Temperature of Solder as it leaves the nozzle. Verify preheating gets your PWB up to 90C-120C prior to soldering. Check machine speed, verify 4 seconds contact with solder at

For Linear Tech LGA's we solder bump the LGA using a .30mm solder ball then reflow with a tacky flux. This will provide a void free solder joint and adds a little height to the solder joint in case you use a flux that you want to clean from under th

| Hi Folks, | Need to draw upon the vast expertise in this forum... | Whenever you fill a new wave solder machine with fresh bar solder, it seems to produce more than the normal amount of dross for a few weeks. I always understood this to be the sol

Guess- If a component drops at the camera the machine will not proceed to attempt to place it and drive the nozzle into a brick of solder paste. The line sensor will catch the fact there is no component on the nozzle and will retry to pick and place.
