"greasy" PCB's
I solder (wave) reguraly some PCB's.
After soldering the PCB's are "greasy". I have tried brushing this off with a clean ESD-safe brush. but all this did was putting the grease on another spot off the PCB and leave some brushstripes. The same with all PCB-cleaners I have tried, some work well if you clean the PCB afterwards with some cloth. Unfortunatly not all produceb PCB's can be cleaned with cloth. Does anyone have a solution for this problem. I thought of a cleaner which cleans the PCB and dries up in powder. But I haven't found one. Alexander |

Have you tried a dishwasher ? most electronic parts store safely at 100C and are in waterproof encapsulations.... Bye. Jasen |

Even if I use less agressive tabs. I have succesfull used a "proffessional" ultrasonic cleaner, but it also uses water and not all parts like water. The grease is only on the solderside so I can use cleaners on that site. |

? Denatured Alcohol ? Flux Remover Sprays ? Etc.

"greasy" PCB's
There are a couple of things that I am wondering about:
1. How is the "grease getting on the boards in the first place. 2. What kind of "grease" is it. I had set up a soldering machine some years ago that used peanut oil as a means of protecting the solder in the reservoir from oxidization. The oil usually didn't touch the boards, but if it had isopropyl alcohol would have cleaned it off. Albert "Art" wrote in message ... ? Denatured Alcohol ? Flux Remover Sprays ? Etc.

"greasy" PCB's
Albert,
You were right about the soldering machine. I (normally don't use it myself) cleaned the whole machine in the vacation of out soldering man. And the problem was gone (for a while). When it returned I got very angry, we now have antoher person at the machine. To prefent the solder from oxidating we use nitrogen, which is won out of air. We use it both in wave soldering and reflow and the results of this are very good. And yes isopropyl alcohol is our primary mean of cleaning PCB's. Alexander "ALBERT C.

"greasy" PCB's
Years ago I got a can from dick smith that came with a tube like a pen tube
with the ink in it, when i sprayed it on the PCB it disolved the greas and was heard of no more but the problem with it was that if I sprayed some types of components they would slightly melt because of the agent and the cold pressure great stuff though try and ask someone at dick smith. sorry I dont remember the name "Alexander" wrote in message ...
