This can be a solution for IC/BGA soldering for lead-free process isn't it ? See, most of the reflow profile set meets solder paste specification but often violating ICs or BGA requirement. Most of the solder paste required temperature of about 205 -

Hi guys, Our vapour phase oven is taking too long to heat up about 15 mins/cycle. Normally its 5 to 6 mins. 2 reasons why. 1.using 10 amp power board 2.heating element not working properly. before i set up a 15 amp outlet i want to know first if my

you should be able to work out the resistance of the heater element from the power rating (watts), and the Voltage its working at. then measure the resistance of the element and see if your anywhere near.

Ps the above answer was to test if the element is failing, if you think the element is not working due to the current supply being limited you can carry out the same calculations but work out the current required then put an ammeter in series with th

Can someone pls help to explain what is the vapour phase reflow soldering technology ? Thx, nifhail

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.

Yes, that's what people are thinking. The 217�C melting temperature that you mention requires a ~250�C reflow temperature. Generally, boards, legend ink, and components cannot take that temperature. Further, few ovens can produce that temperature

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
