I work for a large Contract manufacturer. We use Fuji Siemens and Universal. Universal is by far the most stable reliable system. They always have the parts in stock we need. Great support. Samsung has now pulled out of direct sales in the US. I woul

We can solder and clean lead-free in well-controlled and stable processes. We have no reason to believe that products made with lead-free will be reliabile. We know that lead-free soldering is worse for the environment than other less costly proces

From the equipment side in the last 10-15 years ? I suppose the whole push toward modular machines. Less floor space, increased capability in a single platform - speed of a traditional chip shooter, common spares, blah blah blah. Some of the recogn

I'm attempting to develop paste in hole process so that I can reflow a few plated through hole components on a mixed tech board. Tried various pastes, profiles and stencil thicknesses. Would appreciate any insights and/or pointers anyone can share on

I have seen a few around in PA. Customers seem to like them. Comments I heard was that they're better on smaller components but not so good on large UFP. Mirae (Korean company)is the OEM for the Quad Meridian. Mirae is back with Tyco/Quad for distrib
