Hi there , We just got a 2000 litre Nitrogen tank for our Heller1809MKIII Reflow Oven , it has been installed and calibrated last week but now the Oxigen PPM doesn't drop below 3000 . Did anybody dealt with this issue before ?

We run Zipatec 460's also. I presume that you are running Nitrogen? We have found that if the Nitrogen flow rate is too high into the conical nozzle collar it can be sufficient to disrupt the smooth flow of the solder as it runs down the wettable o

I know that we maintain lower PPM count from our N2 Generators when we can lower the flow rate. I'm not sure if that would help you or not.

Nitro, I msuggest you get your oven manual out and start reading!! it depends on yoru machine, the point of injection, how many zzones it's designed to cover (some only inject for reflow) what your inward flow rate is, what yoru exhaust rate is and

Additionally, increases in temperature can increase the water's rate of reaction with the flux. Sometimes, only a 5 degree change can make the cleaning difference. If the flux inconsistently presents itself, then the likely cause is something in

All, Thanks for your quick response. However, my primary concern is not the question of solderability advantages of nitrogen versus air. With all things (zone temps, track speeds, flow rates, etc.) being equal, what would be the profile differences o

Jason, Something which has not been addressed in the responses so far is the system which utilizes high volume (flow rate of chemistry over the product), versus high pressure, which indeed has the potential to damage very fine webs on fine pitch sten

I use to have that kind of problems with other type of machines and here are the causes: 1- Spray fluxer head partially obstructed (check flow rate) 2- Defective pre-heater probe (manually check temps) 3- PROFILE (last preheat to 280) 4- we sometimes

I'm inclined to believe along with others that if you don't smell it, and the flow rate is consistent (hence, your profiles aren't suffering from fluctuations in temperature due to fluctuations in circulation) you're probably OK. It does beg the que
