I'm trying to design a costing matrix for raw cards so our designers can estimate the costs of their raw card designs, this will hopefully slow down their lust for technology and get them considering project budget costs. Does anyone know of where I

Hi, That's the problem, and in one case it wanted to put 6 reels of 10K resistor, when we only had 10 on the PCB. It really only needed 1 extra feeder, but decided to fill all extra 15 feeders in the bin, so setup is hell. It might think that's a go

Not arguing dan, but are you positive that they are not copper? anyway, what is happening is as the parts sucks down onto the board from reflow the extra paste is notnecessarily sqeezed out but it has no place to go. So it will form this ball on th

This is an OUTSIDE corner spec or an inside corner spec? If outside, I don't see why it is a problem, but will require programming the router or making a template (if an "old school" shop.) Yes, if an inside corner, then it requires a small router

In response to hegemon... This is not a recommended practice but..... We have added a few drops of water soluble flux to our water soluble solder paste when the paste is on the stencil. This was after the paste had "dried" out a bit. We have had

I would start with the following possibilities and solutions: Add extra solder to the pads with a Camalot dispenser; or preformed solder slugs placed as an additional component if there is enough extra pad to attach it without interfering with compo

John, we were responding almost to the same time and I did not see what you were writing. If the glue dots are not consistent within one syringe, than I would blame it on the pump spindle. Do you have an extra one to put on, or clean the spindle wit
