If you teach your feeders, you can no longer gang pick correct? I have never had a dual beam or dual head GSM before. However, if you teach feeders with the fiducial camera and your picks are still off, there is an offset in one or several spindles

Rob is right, you do need to dispense paste or pre-forms when using a laser. Although the Panasonic Soft Beam has a wire despenser. I've seen laser soldering and it does work on smaller stuff. Doesn't work well on connectors even after preheating.

Hi, I don't want to be impolite here, but I must say that it's really weird that because your based on Syria, so you "don't want a US made machine" however I think about 95% of the people on this forum and the forum itself are USA based, so it's ok

We've experienced this issue with SN100. A couple of things we've tried, all with varying levels of success: 1. Longer pre-heats. We use SN100 in a solder pot, and pre-heat the boards on our wave machine. This did have a positive effect, but I ne

Real Chunks...Yes, that's the most glaringly obvious defect in the short term (you'll probably find it on your production floor if it's really bad) but you may find that everything looks good short term only to have a high level of customer returns..
