KRIKIES! If that wasn't a sales pitch, I don't know whut was, me lad. Optimizer is good for DoE's and process characterization, but no substitute for the artform that is wave soldering. When me lads here in Purchasing get PCB's from all over the w

"When the head rotates, it rotates about the center (long) lead of the bug. Therefore, the x/y position of that lead does not change as the head rotates." Heh-heh. You'd think so, wouldn't you? Have you observed this with a magnifying glass? What

Servus! I am currently producing Low volume/high mix on Panasonic CM401-M using PanaPro. For optimzing changeover I am thinking about buying the PanaPro DSM module. We use a self made program at the moment, but it sure is rather a "bettering" than a

LOL! Well I do make the BIG bucks - 8.5 by 11 in size, but our Hi-Scope is the same one Abe Lincoln used in the Civil War. It's old, but does the job. I've had my share of Q.E.s using every thing imaginable to mechanically test the solder. Althou
