SUNSHINE SL-936D Digital Soldering Iron

Guessing the temperature on a knob iron leads to scorched pads on one job and cold joints on the next. The SUNSHINE SL-936D adds a digital LCD, so you set an exact number from 180 to 480°C and the iron remembers it next time.

It has a ceramic 936D heating core, a fine anti-static tip, replaceable 900 series tips and Celsius/Fahrenheit switching. The listing describes an anti-leakage design and a silicone-covered handle.

Jobs it suits

• Small capacitors and resistors that overheat easily.

• Charge port pins with cracked joints.

• Jumper wire on a broken trace.

• Static-sensitive parts near the joint.

Tips

Set a temperature for your usual solder and let the memory hold it. Swap 900 series tips to match the job, keep them tinned, and give each joint fresh flux.

The listing says power and voltage vary by production batch, so we haven't listed them; confirm both with the seller before ordering. It's a step up from knob irons like the SL-908 when repeatable heat matters.
