Which is the suggested soldering temperature in lead free processes? Our experience shows that 90% of solder joints using JBC tools can be performed successfully at 350ºC or less, in any case it is not recommended to exceed 370ºC.
Why is it possible to solder at lower using a JBC tool? It is possible because the tip has an extremely fast thermal response.
On a conventional iron’s tip there is a strong drop in temperature while the tip is transferring the heat to the board. If the thermal response is slow, the tip does not have the time to recover the temperature, especially if a series of solder joint is performed. This is the reason why the operator is used to select a higher temperature, resulting in short tip life and PCB / component damage.
Which are the advantages of soldering at lower temperature?
- The risk of damaging components and pcb through excessive heat transfer is minimised.
- The process quality is optimized because there are less rework issues and scraps.
Which is the suggested sleep temperature? The factory setting of 220ºC is adecuate for most situations. At this temperature oxidation is lowered to a minimum and ramp up to work temperature, when the tool is taken out of it's stand, will be completed in about a second.
