CK: I hear you about pads. Most secondary side SMT pads are primary side SMT pads that are on the secondary side. This only matters when boards are wave soldered. Rather than changing to larger components, consider a bigger fight than that ... ge

Hello, I was wondering about specs on SMT stencil ordering. I am looking to make some sort of template for aperature layout of some parts. I was wondering some issues that you have all came across or made to change to better suit your boards. For ins

Ben, I'm not aware of any 'automatic' method to convert PTH footprints to SMT. Typically, many of the components are passives, and there may be a way in your CAD software to change the passives of a common size to a different footprint. That will co

This will always be the case with in-line spindle machines that rate their cph based on unreal conditions. Flexible placement machines with different head designs will perform better (closer to advertised) and are truley more flexible because you do

We use AOI in-line on most our SMT lines, and still getting them for the rest our lines. It has cut down on Inspection Time considerablly, justifing the cost. They do take a trained technician to program and that is a little time consuming, but worth

Steve, We have had the same problem at my company and unfortunately I do not have any good news for you. We are using a pizza slicer type depanalizer from FKN and if the MLCC caps are layed out too close to the edge they still break. We had to add th

There are times you might want to move the job from one line to another in the middle of the run; ie. machine down. Currently, our SMT is set up like yours, line#2 is just for simple/prototypes jobs. It's easier for us to moves the job from line#1 to
