The alternative is by looking at all your components data specs (heat-range), especially pay more attentions to heat-sensitive comps, and fine-pitch comps, odd-form comps, draw a diagram on a separate sheet of paper shown that temperature VS those ca

The question is can you consistently heat up the board to the desired temperature? You need to measure temperature with thermocouples and plot temp/time diagram. Based on the datasheet chemistry you use, you can see what is the recommendation and if

If that's the case, it's most likely the radio is bad. Again, I'm not clear, but it sounds like using the MD is the trigger to shut the player down: * Stop using the MD. * Fix the MD or some of the associated power supply regulation circuitry. For

Hey Bud: Thanks for the response the other day. We currently use "Jeff�s Method #2: The Drummel Tool." Short answer to your brother is ... yes, probably. Expanding a bit: � It would be surprising not to use a flux to help reflow the solder balls

We're not real clear on the issue. [Got ourselves wrapped around lead (Pb) versus lead (termination), we think.] That aside, comments are: * Boiling point of lead [Pb] is [/K]: 2022 [or 1749 �C (3180 �F)] * It's possible that the material that com

Setting up a PCB washing "system" and the facilities required for a cost effective and repeatable cleaning process depend heavily on the application (water soluble versus chemistry cleaning), (batch cleaner versus ln-line) and local factors (quality

To get the best performance of electronic circuits, components and circuit board supports circuit components and devices in electronic products. Even if the circuit principle diagram design is correct, the printed circuit board is designed improperly
