Tough to say based on what you have told us. Things to Determine are: * Is the heat at the solder connections that are not reflowing properly adequate? * Is the pad surface of the solder connections that are not reflowing properly solderable?

Yannick, If we leave the 201 issue aside; have you checked where those BGA pads are connected to? Could those be power/ground balls connected to large (difficult to heat up) planes by any chance? Erhan

Yeah, perhaps lean more towards a ramp-to-spike profile - reducing the soak time and add a littel heat to your temp above liquid. This has worked for us with water soluable paste as we are not required to use no-clean and utilizing a 6-zone oven. G

Looked at it on the web, I believe that it will place those 600 parts in less than 2 hours! And you guys were thinking that it is slow? Ken, not only will it solder those parts with its blazing speed but did you know that you don't even need a sten

Sorry for delay - been flat out. Sr - I understand what you are saying. My concern is that combined with the head offsets and variations in pick points (i.e. having to teach feeder positions for very slight amounts like 0.05mm)then you cycle times wi

Is anyone currently mounting 0201's with the Hydra/Linescan combination with good results? We have a My series machine and are currently mounting the 0201's with high res camera. The results are good but it is painfully slow. Thanks in advance for

Hi, We have done many 0402's with Hydra. We have done 0201's with the single head on Linescan but have yet to actually run them on Hydra. We now have a machine equipped to do this with the corresponding hydra tips. I will update as soon as I have an

Hi Mike, I haven't tried the 0201s with a Hyrda, but after seeing 20 reviews of your message without a response, I'll try and share my experience with 0402s on a non-Hydra machine. The 0402s are slow, but I managed to get some speed by maxing out

Dear all, What are your views on reworking BGA's? I mean, with the BGA going through reflow temperatures four times or more, and with a manual reballing process, wouldn't it raise up a few reliability issues? Would you consider not doing rework on
