In response to the post concerning the UP1500, the case is a little different. The Speedline/SMTech passwords are hardcoded into the Sigpro.exe file. Here is what you need to know: Login name: Speedline (or SMTech) Passwords are listed in order of ri

Q1 Can anyone explain to me what is the clean and non clean solder? A1 The trend away from CFCs has lead many users to evaluate switching to no-clean soldering processes. The term "no-clean" is actually a common misnomer when used to describe a flux

Russ, Your math is right, but you are converting the wrong direction. I belive: 0201s use millimeters for specification sizes, not inches. And 01005 use millimeters for specification sizes, not inches. And it may be like that for all passives, bu

We use the standard supports that come with the machine. Print a 1:1 transparency of the first pass side of the pcb including mechanical outline and components. Your customer may need to supply this. Flip this over and tape it into position at th

Dhanish, If I understand correct your ICT doesn't detect shorts and only measures capacitive and resistive values. The webbing as Ken mentioned would have a resistance because this is caused by a lack of flux and the web is mainly tin oxide, which w

Shean made some good points and offered some good starting resources. Adding to what he said, I would also mention that many times, even a no-clean flux can cause contamination that requires cleaning. Our lab has dealt with numerous cases of client
