Two (new) soldering question:?
I am soldering four C5707 transistors and four inverter transformers within a Dell 173 FPb LCD monitor.
So given this specific job, my question are:
1. What WATTAGE soldering iron would be good for this undertaking?
2. What SIZE and % (tin, lead, and silver) solder should I use?
3. What compassionate of heatsink can I use? (Would you recommend a regular clip heatsink, or that silicone heatsink grease, or something else?)
If you could be as specific as possible, it would really help me out?
Answer:
I other recommend the lowest wattage possible for soldering on newer PCB's. But 15 watts should be ok.
Always use the smallest diameter solder you can find. I would use 60/40 (tin/lead) rosin core solder.
The standard clip heatsink is what you would want to use.
Heatsink grease is ONLY used to transfer boil from a chip to a stationary heatsink (like on the main CPU of a computer) it is NOT for use surrounded by soldering.
I do have to read aloud that if you are asking these questions, you might want to do some more reading on soldering technique. No offense.
There is a lot more to soldering than freshly picking the correct Iron, solder and heatsink. Getting a solid mechanical and electrical solder cohesive is harder than it seems on newer pcb's.
Bjorn is right on, provided this is not surface mount technology. Clip ons work great for this giving of job.
Good luck
