Steve, I thought these were the same format as the CSM, or very close to it. If so, then your *.BRD file has MNT#, X, Y, R, Nozzle-Skip-Feeder#- LocalFid, Designator, Part. Get rid of the header down to MNT = In Excel parse the file so that you get

Looking for pointers. We have a semi-automatic SMT Techniques stencil printer. We have had some problems with a recent job. Problems were in the areas of finer pitch ics (paste voids as well as paste shorts and some smearing) in certain locations on

Hi Experts, Understand from my friends, PTH crystal can get damage easily when subject to vibration or heat..For example, if crystal drop from table to floor, its internal part already damage @ crack which cannot be seen by eye. Besides, they als

Chris, Appreciate the response - we set FP to "1" last week but no help. The drift is only in the X as well - the Y is never off. We have tried switching the cards to see if if the problem goes to the Y but it doesn't - stays in the X. As for the b

Really, if you start out from the beginning planning to clean the boards, then DON'T use the no-clean flux! The way that stuff is made, it leaves a hard, low-solubility residue that takes a LOT of effort to get clean. If you plan to clean, use a wa

Not much, actually, but that was by choice. We use the Quads for short runs and when we want to get set up and torn down quickly. The Topaz was purchased specifically to give us the ability to get through our larger, regular jobs faster than we can

We've been using fids as badmarks on panelized boards, with reverse recognition so that an uncovered fiducial is a good mark. It's worked fine with 1.5mm fiducials but now we've run into problems with a board with 1mm fids and we can NOT get it to wo

Amen to that!! Too many people lately trying to "get out" of rolling their GD sleeves, attaching thermocouples to the board (using their own preferred method), and running the board and profiler through the oven. I'm sick of questions like "duh, pb

In addition to what robqd3 said, just because you can set your oven to 300� C doesn't mean that (a) it's providing 300� C air, or (b) that your oven will survive the temperatures required to reflow your boards properly. Confirming (a) does mean pro

New to thermal profiling (leaded and lead free), and my boss wants me to search for a better profiler. Currently our model has three ports for thermal couple inputs. We are established in our noraml process but we are relatively new to incorperate m
