Perhaps a little hard to find but is there anyone who uses a vapor phase process to solder populated card with BGAs. I am interested in the success rate of such a process. It is obvious that the throughput is reduce vs a convection oven but still thi

Hi, We have both Vapor Phase ASSCON semi auto as well as Soltec convection inline ovens. I must say we had no end of problems with Vapor Phase. We tried everything, and just could not totally eliminate tomb-stoning completely. We would always get a

Hi, I think you cannot go wrong with Convection. If you want to experiment with VP, just get some of the fluid and put it into a pasta cooker on a standard domestic hot plate. Have a basin full of cold water so after reflow you can lift the cooker a

Dave: In terms of heat transfer, air is 78% nitrogen, and the remainder is mostly (20.9%) oxygen (roughly the same molecular weight as nitrogen), with a bit of argon (0.9%), CO2, hydrogen, monosodium glutamate etc. So you would expect virtually no d

Hi All, We're looking to replace one of our reflow ovens. I'm hoping that someone out there can give me a list of pros and cons of vapor phase vs convection for production reflow. Thanks, Shannon
