nifhail, In a nutshell: Vapor-phase reflow is a process that uses a fluid with a selected boiling point. As condensation of the hot vapor occurs on a cool assembly the assembly's temperature is rapidly raised to match the temperature of the vapor.

thank you Grant and dreamsniper for these shared experiences; I think I'll still try some vapor phase just to have a look to this process, but will focus on a convection as long as it's the actually chosen technology in the company and that it's expe

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

Yes, we are only running no-clean pastes.

Are boards produced using Vapor phase ovens dirtier than N2 Reflow oven. Are there any studies/papers someone can point to? if not what are the methods to verify this? is IPC specified SIR test using 24B SIR test coupons? please advise. thanks in adv

Hi, Yes, I think this sounds like a form of tomb-stoning, and we used vapor phase until it ended up driving us totally nuts trying to deal with tomb-stoning. We tried everything, and all kinds of stencil apertures. Vapor phase is an amazing process

Expanding on a previous poster's comments ... Vapor Phase Soldering. A solder reflow technology that uses a heated solvent to melt the solder. Buried deep in the recesses of the SMTnet Library is �Terms & Definitions�. We started using vapor phas

Hi everybody, now that lead-free is coming, I'm looking forward to change the oven we own in company I work for. Eternal question: what's the best oven technology on market. I allready know that we won't work with IR ovens, but I would like to have

We don't know dip about vapor phase soldering, but we can't help but wonder how well the leads of the component match with the pads on the board.

reduce the stencil aperture to prevent tombstoning in vapor phase process. from my experience a 6 mil thick must be at least between 20 to 30 % aperture reduction for 0805's and below. cheers!
