There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram

Years ago it was common to see 2-3mm keep out areas around BGAs. Now with boards being so densely populated there are no clearance minimums. Regardless if the machine is using convection or IR heating, parts can be reworked without affecting adjace

The ratio of incorrect parts received vs total parts is obviously enormously low, but it has happened. We have also had purchasing order an incorrect part. I always say that SMT can make a lot of crap quickly if a part is wrong, or backwards or what

I am wondering if others are seeing the same issues, and how you are dealing with it. I have found more and more datasheets that no longer have the "Part Marking" indicated. I say no longer, because I have managed to find a few older revisions of th

We were using TL1240Y Tack switches for 2 layered PCB and posted those switches by hand. Now planning to re-spin PCA where we recommend that part to be added on SMT process. So looking for a better and opt switch with same specs. Please suggest me an

I'm wondering why check really? How many times have you had the incoming part incorrect? I've worked a very high volume companies & the incoming components were never reviewed - we had less than a handful of issues in 20 years? Even on those occas

Is anyone familiar with Easy OLP software for Samsung machines? I would like to back up the part info from the machines to the OLP s/w, so when we write new programs, the part info is correct, and matches the info in the machines. I have no documen

This looks like it might be a Fairchild part. Try emailing them with the marking, and see what they say.
