News & technical notes
These are short technical notes about soldering tips: what limits their life, how to read a drawing, and why a geometry works on one joint and fails on the next. They are written by XANJO.
Editorial policy
We do not publish product announcements dressed up as engineering. If a note says a 1.2 mm chisel holds more heat than a 1.2 mm conical tip, it also says by how much and under which setpoint. If we do not have a measurement, we say so rather than filling the gap with an adjective.

A dimension table removes the only reason to call a sales line. That is exactly why it is worth publishing. We explain what A, B, C and D mean on our drawings, how ±0.05 mm on the shank changes what fits, and why a catalogue without measurements is a bet rather than a specification.

At 250 °C, molten tin eats the iron layer. The only question is how long that layer can afford to lose — and why a thick, uneven plating can fail faster than a thin, even one.
Both hold solder. Only one leaves a fillet you can inspect without a microscope. A comparison by pitch, pad width and how much solder the edge can carry.
A 0.02 mm hollow in a 20 mm working face is enough to leave one bond cold. We look at flatness, pressure and pulse profile — in that order.
“Inspected” is not a measurement. The six fields we put on every batch report, and the two we refuse to sign without.
Oxidation, flux residue and a worn orifice change the solder column long before the pump is at fault. A four-step check before you replace the nozzle.
What A/B/C/D mean on our drawings, why shank tolerance decides fit, and what a catalogue without measurements is really asking you to accept.

Send the joint, the iron model or the failure you are seeing. If the answer needs a measurement, we will take one and publish it here.
