Is this what you are looking for? We do this on quite a few boards and it has eliminated component problems from the Cab depaneler (pizza cutter)

FSW, Another suggestions is if you have rail on your product and you are concerned about stress fracturing certain components you could add a routed slot to add relief in that area. So when you snap the rail off their would be no stress in that area

| Any ideas on what to buy? Only need to build surface mount protos, ability to rework. Is a rework station okay? | Will subcontract production after design is proven. Best bet is to get an Elite or OK Industries manual printer if you are not doing

I am looking to discuss 0402 issues, specifically tombstoning/unsoldered. Any recommendations on pad size/spacing, stencil design etc would be helpful. Placement and reflow profile look good.

Steve: Try to find something that�s common to all your skewed parts. We haven�t had much trouble with it except for some MELF diodes a couple of years ago which didn�t look well aligned but made no trouble with specs. Better suited pad design solved

Wow. Never have, never would, but that doesn't mean it couldn't be done. Mostly it just seems impossible to design a carrier clip that could hold both well...more likely it would hold one well and the other poorly, or both poorly. Anyway, is there

Hi everyone if once the exposure time is exceeded the only option is to bake the components. I learned there is an "old spec" for the baking conditions (24h/125C or 192h/40C) and a "new spec" which is the current standard specifying conditions of 4

That would be one BIG spreadsheet, there are a lot of mfg with a lot of components for each one. As you know when going to the datasheetlocator you notice the huge listing of suppliers (500+) each one of them probbaly has anywhere from 1 type of co
