| Does anyone know of an AOI system that can look at the solder joints of SMT chip devices (1206,0805 & 0603) and make a reliable presence/abscence call of the joint on a HASL PCB. A low false call rate (much less than 1%)is required. Any info. fro

| Thanks for the help, Guys. | As a matter of interest, I'm going to look up the standard and see if there's a European (or preferably UK) equivalent. If I find anything, I'll post another Follow Up (though I doubt it holds much interest for you)! |
