Thank you. I spoke with our SMT guy, and he stated that there is plenty of board support on the pcb. So it's not a matter of flexing. There just seems to be inconsistancy in the solder application. He did mention that part of the problem is a lac

Dear Leeg, Generally the faster your print speed the more down pressure you need on the blade to roll the paste and wipe the stencil surface clean. Pastes with higher viscosity need more pressure at slow and high print speeds. Too much pressure cause

Hi Steve, I don't have any experience with CP2's. Sorry .. hazarding a guess though... if they use the analog servo amps like they do in the CP4's, they had a bunch of trimmer pots on them. There is a procedure to zero them using the mecca check mod

dman, This happened to me once on a GSX, but the head was not all the way up. I ended up shutting the machine down, inserting a bypass key so it thought the head was lowered then turning it back on. Then I told it I wanted to raise the head, hit

In my experience, the best way to do a lifted lead inspection on a QFP is by laser height measurement. It is very difficult to consistently catch a lifted lead with only a top down camera. As you say, too many false calls, and still some escapes.

Use the forums nice search feature above. "Lead Free BGA" Lots of info. In short it seems the general consensus is that you are pretty much safe using your lead free BGA in a tin lead process, provided you run your peaks a little higher, and your

What software version and build are you using, and were you lucky enough to get a manual for it? How big are your moduals and what is your component density like? Setting up a MV3-L for IPC 3 will take a serious investment in time for a operator wi

vpblf I actually installed the Uniserver (apache mysql php) WAMP on the AOI machine and there is a setting to make it generate HTML board results, cant remember where off the top of my head. anyhow anyone in the inspection area can now open firefo

I would go with AOI. Reasons are: --AOIs are faster --They have more coverage. Given, you cannot test the value of components, but the AOI will ensure that all resistors are correct, orientation of ICs are proper and components are present on the

We designed a fairly simple software called PROCAM to do exactly that! It takes 2 Gerber layers - Paste/Mask layer and the Silk layer. Within minutes you can extract all the centroids. PROCAM has a standard excel output with all the centroids, fiduci
