Try Assembl�on. The 2.0 version just came out so the 1.x versions are probably no longer available. I believe they start charging you for it now, but it won't be much since the previous versions were free. If you can manage to track down a 1.x versi

Thanks Doctor - as always, you're right. I must've been typing with my mittens on. It's starting to get cold on this part of the planet these days. I wasn't blaming anyone, just trying to take a few questions marks away so "we're" left with the an

Guys, We have an issue with a Board we are running at the moment. We have 3 BGAs on the board 1 Leadfree and 2 are not. We are running a Leaded Process and the LF part is not available Leaded. What do we do? I reckon that all we can do is try an

Listen, you should try to utilize wave solder as well. High speed gadgets are fine if you want to make things complictded, but if your just starting things up, think simple. Nothing beats wave for solder many parts at the same time. If you can't p

Hi, How come so many good threads get off track because of this Guru fool. To get back on track, we have been running SN100C in our pot for a few weeks now, and it's incredible, and working really well. Glad I listened to the advise of people on th

Hi, In our setup what we usually avoid is to use RoHS BGA on Pb process. But we use sometimes Pb transistor(4~6pins) on RoHS process, no BGA yet have been reported. Its really difficult to say about reability unless you start running some functional

Yes, leadfree paste is dispensable, but there is a completely diffrent paste than one will use at the stencil printer in the line. This is a very tricky one to deal with. We use xxx lf-free paste in the line, but that paste will Not at all work at th

Some amount of voiding was always seen on sites where solder paste is printed. These voids are much smaller. However the site where a flip chip is flux dipped has never had problems with voiding. Macro voids (and huge ones at that)across the board s
