Hi Guys, Well I guess a little more info would be helpful. Seems everybody is typically mentioning cheaper little stations. Maybe they are fine but I suspect they don't go far enough for what we are looking for. I have never used any of these things so pardon my ignorance. What we will typically be using it for reworking your regular assortment of QFPs, QFNs, SOIC, TQFP, PLCC and TSOP devices. A fair number of devices that give us the greatest difficulties are the ones containing a central Tab pad under the device (and there are becoming more of these each day). There would/could be some attempts to use it for BGAs but they are not the largest concern because we have no way to inspect BGAs anyway. Most devices don't give our people much trouble until it comes to those with the central thermal pad. So we believe that what we are looking for would probably best include a hotplate to assist heating the board from underneath, then the regular assortment of air nozzles/hoods with some form of vacuum nozzle to pick the device off the board as it is freed. The engineer looking at this has commented that he is thinking we may have to get a Metcal station that costs approx. $70K. I told him I had seen various comments from members of this group so I would make an enquiry for him.

Hi Brad, Too remove, replace BGA type components I guess ?
