I've got a set of apertures on a stencil that I would like to "plug" or block off. In the past we've done this with Kapton tape, but since this location is close to a fine pitch component, the thickness of the tape prevents good gasketing at the fin

Dave: After the stencil was made with apertures for a connector on this PCB, it was discovered that the connector would have to be handsoldered after SMT reflow. If the solder deposits are left to reflow on the pads, it makes it difficult for the o

We are thinking of changing our solderbar supplier,due to a significant price increase from our current supplier.My question is, if the alloy is the the same, is it just a case of topping up the solderpot with the solderbars from our new supplier, as

A quick question(s) to anyone who operates SMT lines with only one multi purpose flex machine (P&P). What is an ample feeder count for this machine?...and secondly, do you have a standard kit of common parts that you would wish to reside permanantly

Even though you use a no clean process, it is still possible that some type of fluid has created the "short". Production lines are notorious for using cleaning chemicals on PCBs to clean excess flux after rework on other areas. Unless this type of c

Hi, I'm a non-technical person working for a small MFG company that uses SMT. We are experiencing a high level of board failures due to "insufficent soder". Where is the best place for me to get data to bring myself up to a level of knowlegde on
