Electric soldering iron is the most common welding tool used by electronic engineers.Good at use of electric irons will save us a lot of time. This article will detail the use of electric soldering irons through preparation, welding and soldering techniques, and, of course, key welding techniques.
(I) The preparatory work
1. Use finesand paper to polish the
Conformal coating is a specially formulated coating used to protect the circuit boards from environmental erosion. Conformal coating has good resistance in high temperature and low temperature. It is a transparent protective film after solidification. It has excellent insulation, moisture resistance, anti leakage, shock proof, dustproof, anti-corrosion, anti-aging and corona resistance.
We often see the metal
With the development of science and technology, technical requirements, and now more and more circuit board using surface mount components, compared with the traditional package, it can reduce the area of the circuit board, easy batch processing, high density wiring.The chip inductance of chip resistor and capacitor is greatly reduced,
