More eloquence and cowardice. In the words of Dave F "what a maroon!" Another noname without the intelligence or conviction to offer a good response or even a name. And the forum continues its self degradation. Pompous MoonAssMan Boogie

Question: Do you run your pallets hot or cold thru the wave? I ask this because if you run your pallets cold the board will never preheat to the correct temp. thus, your flux won't activate properly. James

The board and pallet are at room temperature when they pass thru the flux, then are sent thru a pre-heat section, and lastly sent over the wave solder. The exposed portions of the board solder properly.

James, I'm a little curious about your wave solder process. Could you kindly discribe it and list the approximate associated temperatures? I think I'll fiddle with the spray flux idea. Thanks James and Wolfgang for your inputs. Ron

Hello sirs, Would you kindly provide me the best way to erase the flux attached on the golden fingers? What we can do now is to use the pencil eraser to remove the flux. Thanks in advance. Gyver

Hello Dave, The gold fingers are on graphic cards. What did you mean by DI water? I need to know that very soon, thanks a lot! Sincerely, Gyver

Yeh, gold fingers are always on any kind of cards. I just can't figure-out why.
