About this product
Mijing SW-03 is a USB-powered repair pen for locating short circuits on mobile phone motherboards and small PCBs. It heats rosin inside its atomizer chamber to produce visible smoke, which is directed over the powered fault area so the hot spot can be found under a microscope. This version has no built-in battery and needs a stable 5V USB supply during operation.
