Re: Conformal Coating on control boards not allowing me to solder

MEK???

yes this coating seems invincible, i learned how to solder (not perfectly) and am anxious to get into swapping the caps on the boards i wish to fix, but this coating about has me ready to quit, The most effective thing i can think of is the micro media blaster which isnt cheap, but if its something im going to be doing alot of, i dont mind buying it

Re: Conformal Coating on control boards not allowing me to solder

so three methods tried, three methods failed.... fiberglass scratch pen is out of question, Conformal coating remover pen is out of the question, and heat hasnt done much of any help

the farthest ive gotten is with a razor blade, but i had trouble doing it

Re: Conformal Coating on control boards not allowing me to solder

the fiberglass scratch pen was an utter failure, while messing with the boards, i discovered one version of the boards is light green versus dark green as pictured, and i can actually flake off the coating from the other board that is light green

the scratch pen did little to nothing to the coating on both boards, thats why i grabbed a razor blade and figured id try a few things out

i ordered some conformal coating remover pens to see if that would help, im not finding much information on...

Re: Conformal Coating on control boards not allowing me to solder

i ordered a fiberglass scratch pen just to see if that would work, the coating seems very hard and applied to the entire surface of the board up to around the very edges, i just want to make it an efficient process, because i will be replacing ALOT of them once i get past this coating ordeal, of course im gonna practice on quite a few boards before officially putting them in machines

Re: Conformal Coating on control boards not allowing me to solder

hows the Conformal coating remover pen from Mouser Electronics?, i see theres a few Pens which claim to remove the coatings, but im debating if theyre safe or not, as i have no experience with this

Re: Conformal Coating on control boards not allowing me to solder



No i didnt know that, but ive been reading and researching and now see one key thing im missing Flux......


But the board is pretty coated in this stuff, the joints appear to be coated with it, the same shine on the board is covering the solder joint

i am an appliance tech specializing in digitally controlled washing machines, and am looking to replace This blown capacitor

Problem is, the board has a coating on the backside of it which will not allow me to solder or desolder the bad cap i want to change, ive been hunting up and down, and have come up with a conformal coating remover pen or micro abrasive blasting to be the only methods to removing this coating

and thats why im posting this thread, i intend...

Re: New Members - please post your introductions here

Hi, My name is Mike, im an appliance repair technician, and am learning how to solder, figured id join to learn a bit more, because i got into it just to learn how to change caps on control boards for appliances, but im quite interested in soldering after reading, watching and attempting to do things in a trial n error with junk boards, i think ive gotten it down, just here to expand my knowledge in this field
