Soldering Circuit Boards Pcb

Soldering Circuit Boards Pcb is often the most common form of soldering. The basics are easy to understand, but you still need to master certain skills through practice. The best way to do this is to buy a simple electronic component or assemble a simple circuit on a multiwell plate.

Product Details


Soldering Circuit Boards Pcb


The advantages of PCB assembly are as follows:

1. Small size of electronic products

The volume of welded components is only about 1/10 of that of traditional cartridge components. Generally, after SMT SMT processing, the volume of electronic products can be reduced by 40%~60%.

2. Low efficiency and cost

PCB is easy to realize automation, improve production efficiency, save material, energy, equipment, manpower, time, reduce cost by 30%~50%.

3. Light weight

The weight of the SMT component is only 10% of that of the conventional cartridge, and the SMT can reduce the weight by 60%~80%.

4. High reliability and strong anti-vibration ability.

5, good high-frequency characteristics, reduce electromagnetic and rf interference.

6. Low defect rate of solder joints.
