Keep in mind you'll still need to preheat the assembly to properly activate the flux/drive off volatiles in the paste. Perhaps a convection toaster oven... Add some cooling coils and a freeboard/tube to the top of your pasta cooker or turkey fryer t

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

Hi, When I started out and we were the same we got an old MYDATA TP9-2U. It places everything, and you should be able to get a cheap one second hand, that will perform very well. They have vision as well, as an options, and that works very well. I w

Hi, Yes, all you really need to do is boil the fluid while suspending the PCB above the vapor, so it's quite easy. However I would recommend against dropping the board direct into the vapor cloud, as that would be a very fast warm up, while letting

Hi, I off center idea we used when we started. Get a pasta cooker, and put in vapor phase fluid, and then use that. Place the product in the bottom of the inner pot, and then heat on a small hot plate. When the vapor cloud gets high enough and the

Do you think it would be possible to make a home made vapour phase machine for say $500. What I am think is making an 18 inch square cube type box with a transparrent lid out of s/s or copper. Fit some heating element to the base to heat the liquid

Hi, We used it previously a few years ago, and I think I posted some comments on it here in the forum in the past you might want to search out. It's a weird process, because it solders incredibly, and I mean it's incredible. There is no oxygen, so

I was wondering how hard it would be to make a homebrew vapour phase oven, to avoid the problems with very cheap conventional batch ovens, in particular uniformity. I've seen a reference here to a pasta cooker VP setup, but the image link is dead no

Hi, It was funny. The sight of 3 men standing around the microwave daring each other to push the start button, and then freaking out when the whole thing looked as though it was going to explode was funny. I guess you have to try these things! Tho

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
