Hi, What are you doing for reflow. Sounds like a cheap MYDATA TP machine second hand might do the trick, but don't know if it could do 0201 though. You can get a fairly ok manual stencil printer that might do the trick. We had one that had a linear

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

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

Sorry, I haven't checked the forum for quite some time. HS and SP require a line computer. The computer in the machine is the same computer than the line computer out of the HP 300 serie. HP discontinued manufacturing these computers in 1996. The 332

I appreciate the detailed reply. However, I had tried dimensioning the stencil to everything imaginable, including the correct/measured dimensions. Interestingly enough, after loading a new stencil into our adaptor, I had no errors with the new pro

Thanks for the suggestions. We have been going around the dome to pick from the base. The placement machines are Panasonic chipshooters - MV2VB and MV2C. I have several problems with the MV2C. The K-type feeder plates were moved by my predeces

They are expensive so you need to have a lot of jobs that take a long time to hand solder or have a ton of masking. Also look at bottom side wave soldering, if you are having a lot of defects, the selective will allow you to solder both sides in surf
