----------------------- Gerhard, using too low of a temperature is more likely to harm delicate components than using a higher temperature. You do not want to hold an iron on the joint too long, even at 300C. It should be hot enough for the solder to flow within 2 or 3 seconds at the most. So cranking up the temperature close to 400C and getting the solder to flow quickly is easier on most parts - especially the I.C.s, transistors and diodes. I normally work at 375C (700F). That brings up another point for anyone using de-soldering braid. In that case 375C (700F) is not hot enough. The braid will pull too much heat away from the joint, meaning the joint has to "cook" for a long time to melt the solder. Like most of us, I prefer a solder sucker type of tool, but when I choose braid, I find no problem getting it to work with the iron at 425C (800F). "Cooking" a joint with a cooler iron will more likely debond the trace from the board!
