I would ditto CAL, we have a jewel box 90 with the 5 axis and we love it. I really like being able to tilt,rotate,and move side to side front to back, Angle viewing under a BGA can be very informative as to the quality of reflow in seeing ball coll

I used an old camalot 1818 with solder paste dispener system to do 0402 components on LTCC. It worked very well, but there are tricks that you have to learn. Volume and placement of the dots is critical. I am sure the latest dispense equipment have s

I know your frustration. CP6 feeders are notorious for this issue. They have always been an issue. You have probably went through the "change spring, change tape leaf, change component reel, place peeler tape over two rollers instead of three" scenar

People like flat surfaces for placing and reflowing certain components, like fine pitch devices. Some board suppliers can supply HASL that is flat and well controlled from an amount of material stand-point. Unlike OSP, HASL has a wonderful shelf-li

I'm having a philisophical discussion with my boss regarding long reflow soak times to improve soldering under BGA devices. Is there anything to be gained by extending soak times at the 150C level from 60-90 seconds to 5-10 minutes? I've never seen

Quality, consistency and labor savings all wrapped up into one nicely packaged piece of electro-mechanical marvel called AOI. Look for the number of templates one can store per component, lighting options, can it do through hole? Look at reporting

Hello Everyone, We are having some problem with Palladium-Silver surface finish. We have ceramic components with the above surface finish. When we try to assemble these on Sn/Pb solder, we are observing open joints. If we reflow the compt for more t

We use ssd on all components, from 0201 to very large fine pitch and bga's. With some very small micro bga's , if there is a problem with bridging, we will tape off the stencil during the ssd process and just use bare pads...along with the solder fr
