We expect aerospace to be IPC-A-610, Class 3 and J-STD-001, Class 3. The above quality statement stecifies: * "IPC 610, Class 2 acceptability." This is unclear. Should this be "IPC-A-610, Class 2 acceptability?" * No class for J-STD-001. Should we a

For most applications, a nice square [or rectangle] pad works just fine. Assemblers ship boat loads of boards with these every day. It's reasonable for tight decoupling capacitor requirement applications to use round or radiused pads for components

well by the looks of it you have pretty much replaced just about everything that could cause the problem. The only one i haven't seen is the cable going from the computer box up to the x-wagon boards. Just out of curiosity when you took your motor fr

I placed almost nothing but 0402 components on the Contact 3AV and 3Z machines I had. I will admit that there are better machines for placing 0402 components. Not sure why the 3AVX would perform poorly at 0402 placement. The feeders have a X & Y a

I don't, My desk causally is piled with papers, programming printouts, PCB's with defects to be resolved, and spare/broken parts from the SMT machines. For me its more important to help the SMT department and SMT Inspection department get better or

So, someone is going to get a chance to buy a nice and shiny oven, eh? Summary from my notes of old thread on SMTnet: Some people melt sugar and use that solution to clean cooked-on flux residue. Dissolve sugar into warm water, spray it on the area t
