Mark, This is a big topic. Where are you located, it would probably be best to hook you up with someone in your area. Anyhow, lead or lead free should be based on whether the circuits are lead or lead free. I would guess that cell phones would all

I'm in North Attleboro, small world. To answer your question, you can deposit small dots of paste with a syringe. Kind of tricky work, and there are small stencil soluions out there fairly inexpensively. See http://www.minimicrostencil.com/ (I do

I'm new in SMT and the company I'm working with has already purchased SMFL-3000 manual pick & place system with hot air and we don't have reflow oven. We are now starting design SMT board. My question is, how we reflow the solder? After all component

hi all What do you think about soldering pb-free in reflow oven (air) lenght 1,7m (5 zones top,bottom) with max zone temp. 300C? Do you think that this process will be stable? Our max PCb dimension 260x260 mm. When i compare different oven producer t

Its not the max temperature that is the issue, its how much energy the oven is capable of transferring to the PCB inside the 4-6 minute window of a typical profile. In a conveyor oven this is achieved by having zones of different temperatures, but th

As others have said, you'll have some difficulties getting good reflow on pb-free out of a 3-zone oven. We did it with a 4-zone for awhile, but only had really good success on low thermal density boards. That said, you should definitely check your
