Phil The TIME predicament you talk about is something we "consultants" deal with every day. We certainly understand the issue. Interestingly, some of us think that TRUE root cause thinking WILL NOT OCCUR until or unless it is driven from the BOTTO

Dave, It gladen's my heart to hear that I'm not the only person with problem's like this, and also that the forum is as good as ever. So route causes and consultants or JAFO's as I call them...Just Another Friggin Obstruction!. I hate the way that

You are mixing long exposed paste back into fresh? How long has your fresh jar been open to the air? You are probably doing yourself a disservice by scavenging the paste (it could have moisture entrapped). Your visocity has definitely changed. You a

Have you had bad experiences? We have a paste checker on line, and all components are verified at receiving and again when loaded on the machines. The purpose of AOI ( for us anyway ) is to reduce the time spent after reflow visually checking the b

FYI- Toe Fillets have not been required per IPC 610b/c (they are nice to have though). Remember before Solder paste inspection equipment The Solder powder type/size, stencil type, and apertures are what defined volume. The need has not been until rec

Maybe there's no test and I don't know where or why my customer came with that requirement (I think because in one of the board shipments he got a board were a smd resistor broke, but I think that happened because miss handling), but anyway I need so
