You're soldering fine-pitch flat ICs and CMOS chips, and your current iron's current leakage is a real risk to the board. The Goot 15W iron uses a ceramic heater that auto-adjusts to the tip's heating load, so heat recovery stays sharp after every joint. High insulation and low current leakage mean your precision work stays safe. The zero-volt switch circuit kills the hum you get from cheaper irons. Tip runs at 320°C. Silicon rubber lead flexes without kinking. Ribbed rubber grip means it stays in your hand when your fingers are damp. Made in Japan. Carries Electricity Safety Approval SAITE20185 and a one-year warranty. Spare tips: TS-1432 (0.5mm conical, as supplied) or TS-1434 (0.3mm conical). Pick up the iron when your current one can't keep up with fine-pitch work
