| 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)! |

| HASL: (hot air solder leveling) is a process used to cover the Cu. Either Sn/Pb is used or Ni/Au or some other combo. In one case you create a land pad and in the other (with resin)you cover the Cu so that you only have a "trace." Is that correct s

| | | Board shops and us, the user, have a lot on our hands. As far as getting traces - this is done using an etch resist before solder mask and the HASL processes are performed. | So when in the process is HASL performed?? | | | With tin/lead pla
