JBC extends the C245 cartridge range with 4 new models

Work faster and increase productivity with special cartridges for specific soldering applications.

JBC cartridges offer excellent heat transfer, great durability and instantaneous heating up. By using the sleep & hibernation mode, a tip life lasts up to 5 times longer.

C245-771 Cartridge Bent 1 x 0.1
Special cartridge with bent tip for soldering between pins.

C245-772 Cartridge Nickel 1.4 x 0.7 S1
Special cartridge with pure nickel tip for HMP (High Melting Point) soldering. 

It replaces the C245-753 cartridge since its thermal performance has been improved by as much as 25%. The operator can work faster and increase productivity.

C245-773 Cartridge Chisel 0.8 x 0.3
This cartridge is a slender version of the C245742 for general soldering.

C245-774 Cartridge Chisel 1.2 x 0.3
This is the slender version of the C245906 for general soldering.

C245 Cartridges work with T245 handpieces and also with T470 handpieces only when being used with Modular stations.

Soldering temperatures

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 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.
