Yes, you cannot change the "subject" that you enter when first beginning a tread. This is what will appear on the Main Conference. You can change the very same "subject" as it appears when the thread is selected in one of the Forums with "edit" or

Out of curiosity, what method did you use? I ask because I have used acetone on a Q-Tip to clean up boards after rework for some time and haven't noticed anything like that. Did you notice it right away? Or after some time went by? I may need to re-

We are using a water soluable process, and we have no fear of washing the boards after the crystals have been placed. Any type of SMT crystal I have reflowed with no fear, thats why this practice troubles me, and I want to remove it altogether. I w

Hi all, There are no ground layers which makes the non wetting rate a bit confounding. The foam fluxer has not been cleaned in a while though, while there is a strong evidence of fluxing by running blank paper and looking up the top side

Hello, We had serval times problems with wavesoldering medium and low density boards. After analysis one time the problems where in the carrier an other time the flux was Not visible contaminated, ...etc. I wonder, does any one know a complete wav

hello all, I�m experiencing problems with "warped" boards after first reflow, some of them i just can�t print side two due to this problem,,is it related only to reflow? i�m using a linear profile (225� peak / 70s time above) with a tin lead paste,t

No, there are no issues with mixed lead / no-lead post-reflow cleaning. No-lead is a little harder to clean so be sure you use the appropriate parameters and cleaning chemical. The only potential issue is if you mix up the boards after cleaning,

Vick I would not think what your seeing is normal. Just guessing without a profile but.... - not reaching peak temperature - not enough soak time or mild ramp to burn away the flux - shortened TAL, not allowing proper time for the solder to wet - lo

I think Sr is right. Miss prints are prolly a result of your tooling moving the board after the camera looks at the fids. It also could be the camera itself hitting the board from warpped board or tooling raising the board up. It may be the camera
