| 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

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

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

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

Edmund, Check your "Air Amp" settings or the equivalent on your oven. Sounds to me like they are probably turned up too high in the reflow zone and you are blowing the components off of the board when the solder goes liquidous. Regards, Justin

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

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

The easiest way to remove air bubbles from any fluid is to place it into a vacuum chamber. I do this almost daily with liquid rubber coatings, glues, and plastics.
