As per Travis's reply it could be something other than the reflow process. Another good one is if the printed PCB's have been cleaned down due to print misregistration etc.. If not properly controlled paste residues can remain distributed about the p

Hey Bud: I'm not clear on the details, but Philips distributes Yamaha in the US and Europe (?). Maybe the folks down in Alpharetta GA can help you. I think the Philips chipshooter is the fastest machine on the market and they have two very accurate

Wussamatta with PC Fab? Other than PC Fab, try: � SMTnet Industry Directory lists 250 (or so) fabricators � Printed Wiring Board Resource Center, Printed Wiring Board Facility Directory (http://www.pwbrc.org) has a huge shop listing by US state � As

Hello Daniel !! You can use a stick vibrator for BGA on IP2 machine. Make a slider in the right shape, and put insert the BGA as a regular component. For the part data use only the contour of the component (ignore the balls). I can asure you that the

Hi A better method wolud be to use a belt feeder the reason being the vibratory feeders tend to blow mfu signal ports I believe you can retrofit your machine to take the BGA also if the bga has no matrix pattern in the centre there is no re

Best bet is to use Tecnomatics Unicam software. This is similar to Fujicam that I believe comes with Fujis. Initial part library comes with all the insdustry standard part classification. For new parts / odd parts you can add to the library. Try www

One of the major problems with snap off's is heat from the wave weakens the joints. Try using more holes but smaller size. V-grooves may also be an option, but depth control is a problem as most are not NC machine controlled. Direction through the wa

Thanks for your help guys. We've V-scored boards in the past and it led to difficulties, as mentioned with the depth of groove etc... Our PCB's vary in shape and size drastically, and I mean drastically. So it looks as if a little more though on wh
