SDG #233 JBC AM120 and Metcal MX-PTZ Desoldering Tweezers

Desoldering tweezers occupy an awkward position in most workshops: they are expensive, they only do one job, and hot air can often substitute. This comparison puts two of the most credible options side by side, the JBC AM120 handpiece and the Metcal MX-PTZ, to establish whether either justifies the outlay for a hobbyist or small repair shop.

The two take noticeably different approaches. The Metcal cartridges rely on the company’s Curie point self regulating technology, so tip temperature is fixed by the cartridge fitted rather than set on the station, which keeps things simple but requires buying the right cartridge for the job. The JBC handpiece pairs with JBC’s controller ecosystem, giving adjustable setpoints, sleep behaviour when the tool is racked, and the very fast recovery JBC is known for. Tip alignment, jaw pressure and how well the pair of tips actually meet matter more than raw wattage here, and that is where the practical differences appear when gripping small two terminal parts.

The hands on portion covers removing passives, SOT and multi-lead packages, and shows how tweezers can lift a part cleanly without disturbing neighbouring components or blowing lightweight parts across the board, which is the main argument for owning a set at all. Ergonomics also receive attention: weight, cable stiffness and how easily a component can be pinched without rolling it are the things noticed after an hour of rework.

Buyers should treat this as a specialist addition rather than a hot air replacement. For anyone already running one of these station ecosystems, adding the matching tweezer handpiece is the cheaper path than switching brands.
