| Hello, | I need some users information about "Air knif" in wave soldering: | 1. Does it decreases bridging ? | 2. Is it self installed of a purchesed kit (if purchesed, who are the recomended vendors) ? | 3. Any other information about the issue. |

ken, in order to improve the wettability I suppose.... But it seems that jimk wants N2 for the reflow owen even if he does not need N2... ==== jimk: see air-liquide, linde gaz, and praxair , you can by N2 liquid in tank , or any other conditionnemen

Air liquide has some great articles on this www.airliquide.com Cal

Try this link out. http://www.airliquide.com/us/ep&a/TechPapers.htm Air Liquide has done many studies on this topic. There should be some useful information there. Cal Caldon W. Driscoll ACI USA 610-362-1200 cdriscoll@aciusa.org

Do you reflow both sides of the boards before washing? Sometimes these white residues occur from "burnt" flux. we see this from time to time especially when using hot air and liquid flux. Russ

Yep i agree most likely misplacment or reflow, maybe check your air flow around the liquidous zones(if convection oven) probably too low.

No matter what type container you use, air in the delivery line will always be a problem. When you pop the lid on a pressurized container, fill it with a liquid and reseal it, air will be present over the liquid. Where do you think it goes?It has to

I am looking for a consistent method of applying no clean liquid flux to solder pads. My main concern is if I use a standard air-over type dispenser mounted to an automated arm that the liquid flux will make a mess and not be consistent. I'm not to

I'd speculate that the properties of a well formed solder connection processed in air and N2 are indistinguishable. Then again, the pitch is that N2 gives a wider process window, especially for NC flux-types. In the SMTnet Library look for: �Opti

Non-Hermetically sealed parts are parts are not air tight and gasses and liquids will pass into the package of the part and come in contact with the electrical or other components within the package (i.e. some switches, relays, transformers, etc.) D
