Hello ricardof, To implement Cpk studies on SMT production equipment, you will require highly accurate glass plates, glass component slugs, accurately manufactured stencils and a measurement system to perform X, Y and Theta positional deviations from

Hi I thought I would come back to this one for a second. Joe Fox above gave a nice concise note as to why you must raise the temp high enough above the soldering melting temp (liquidus) yet not too high. You want to go high enough for paste so tha

Iman When you talk about your profile, can we assume you're measuring it on the pads of LGA? Profile the solder paste reflow by placing a thermal couple under the component pad, similar to a BGA. On a slight tangent, as with soldering BGA, paste

Thanks Scott,Iman, The problem has been isolated to detachment from package so I believe that there are no fabrication issues related to the Gold on the PCB. What is a Moyet analisys? where can I find more info? Dave, I am still waiting on Altera t

Well, first off now I'm just starting to believe that we are fracturing again. But here is some more input D1 ENIG? I would not have thought that they would be but as usual you are probably right. D2 Again I would have to agree about it should affe

There is a japanese company that makes a ultrasonic hand-held stencil cleaner. I demo'd it for a day and it was fantastic! It even cleaned epoxy stencils. Can't recall the price...but it should be much much less than the smart sonic and other "mac

The camera is not driven from the motor cards. The camera is attached to what is called a forcer. For the Y axis there are two of them. One is wired backwards from the other. one of the forcers is connected to a flex chanell for the air and electrica

We are having a problem with our Heller 1800W oven with certian parts skewing. It seems that some inductors and taller Can caps are shifting around in the oven. It seems it will solder fine and than all of a sudden just be off to one side or the othe
