Chip-Quick is the best, we seem to blow chips into our prototype boards quite often and this is nothing but Chip-Quick to replace fine-pitch 100-pin SMD chips without overheating and damage the PCB charges. Many do not yet know this wonderful product. We use so much I bought this because there aren't many in the sets and we used a few, it's a lot cheaper. Take a large ChipQuick syringe with a special flux to go with it, nothing else will work.
