4phones continues to complete its tools offer with the incorporation of the international JBC soldering brand, an efficient brand of workstations, soldering tips, heat, hibernation systems and much more.
In future posts we will talk a little more about JBC products, and we will present technical operating tips that will surely help you in your repairs.
On this occasion we will talk about the ideal welding temperatures in different processes.
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 tips last much longer because of reduced oxidation. This improves the wettability of the tip and therefore also the heat transfer efficiency.
- The flux does not burn directly on the tip, but is activated while soldering. In this way, the tip does not turn dark so quickly and its wettability is better.
- The risk of damaging components and pcb through excessive heat transfer is minimized.
- 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 adequate 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.
How do I calibrate my station?
Since the technology is based on a microprocessor drive Advanced stations do not require calibration.
