SDG #232 New Aixun T3B JBC Style C210 and C115 Soldering Station (also T210 or T115)

The Aixun T3B is the small-tip sibling to the popular T3A, built around JBC style C210 cartridges with optional support for the even finer C115 range. That makes it aimed squarely at fine pitch SMD work, microsoldering and board level repair rather than general purpose assembly, where the larger T245 style handpieces still make more sense.

The review works through the control unit’s construction and user interface before opening it up to look at how the power supply, drive circuitry and thermocouple sensing are implemented. That internal inspection matters on cartridge stations, because the quality of the temperature measurement front end and the mains isolation are what separate a genuinely usable clone from a cheap approximation. The C210 handpiece itself is examined for cable flexibility, grip diameter and cartridge retention, all of which have a direct effect on how comfortable long microsoldering sessions are.

The practical testing covers first power-up behaviour, sleep and wake response, then a calibration check comparing the displayed setpoint against measured tip temperature so buyers know how far off the readout is likely to be out of the box. A basic soldering test follows, showing how quickly the small thermal mass of a C210 cartridge recovers on real joints.

For anyone weighing up a genuine JBC against the Aixun alternative, the useful takeaway is where the compromises actually sit: cartridge compatibility, temperature accuracy and handpiece ergonomics, rather than headline wattage figures. It is a strong option if your work is predominantly fine pitch, with the caveat that C210 tips have limited thermal reserve for heavier joints.
