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.

Hi, Encountered this deference to the vapour phase process that was supposedly "phased" out years ago? *pardon the pun* Any comments from folks who have used this proces before? how about folks who are currently using this process? even better, a

Absolutely! The Solder paste needs to be brought to room temperature or close before opening. It like bringing a cold glass from the refrigerator when the humidity is high,water will condensate on the glass. It also will condensate on the solder and

"Phased out" is not the correct term. " Not economic" might be more appropriate. Check: R&D Technical Services (Centech) 12261 Suite A Nicollet Ave S Burnsville, MN 55337 (612) 707-1931 fax 6739 sales@rdtechnicalservices Further, Graham Naisbatt

I don't fully understand what you are trying to do... 1. Reflow Solder in a Vacuum Temp Chamber 2. Vapor Phase / Condensation Solder with Vacuum 3. Contact Heat system with Vacuum 4. Inline Reflow Oven with Vacuum ... or what you are trying to sold

Regarding the non-adherence of this maintenance schedule......should we expect to see flux condensate on our solder joints?? Possibly leading to solder joint contamination, dry joints, solderability issues in production etc.??

Steve, If you can get me your snail-mail address, I will send you some latest information. We actually have a totally new system called Delta 5. It is Condensation Soldering rather than Vapour phase, the difference being that we solder in an air ti

Paramjeet Singh Gill Flip chip with aqueous flux, that's interesting. * What is the stand-off from the board is your flip chip? * What machinery and materials do you use clean your boards? * How do determine the cleanliness of the board under the fl

Moisture will condensed on your paste if the temperature different. Solder bead will happen. You can see the jar or cartridge wet when you removed your paste from refrigerator.
