Several of our customers use our Summit series equipment for this purpose. Our rework stations are used in proto labs to prove manufacturability. Consider it a low volume, semiautomatic pick and place and selective soldering reflow oven. Some low

Mornin! We just had vendor in here pitching a "low-temperature rework system" which was intriguing, but too expensive. He did get me to thinking though, beyond heating ceramic caps before hand-soldering them, it seems like it would be advantag
