This article updates one I wrote for Printed Circuit Fabrication Magazine in December 1991. Actually, this article trashes that - and about time. I was much too kind then talking about how to control the HASL process. I really couldn't say it was uncontrollable, as no one, at that time, would have believed such an "advanced", save us all technology could be flawed. Well, it's time to dispel that bunk though some still love the stuff, and there are many staunch defenders selling equipment and process elements as well as those using its effects...
Used by electronics manufacturers ProntoTEST-FIXTURE designs the "bed of nails" test fixture and generates circuit description files your Automatic Test Equipment (ATE). Instantly finds non-probable nets, optimizes probe placement and size, creates fixture fabrications files, etc.
ProntoTEST-FIXTURE supports most popular In-circuit ATE and MDA. Also supports Flying Probe testers such as Teradyne Javelin, Takaya, Scorpion, Spea, Polar Instruments, Acculogic, Seica, Aeroflex, Hioki, etc.

BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
