Soldering characteristics of pcb board maker

 

The solder characteristics of the pcb board maker are as follows:

 

Soldering characteristics of pcb board maker

Soldering characteristics of pcb board maker

1, Has good electrical conductivity: because tin, lead solder are good conductors, so its resistance is very small.

2, It has strong adhesion to component leads and other wires and is not easy to fall off.

3, Low melting point: it can be melted at 180 ° C, using 25W external heating or 20W internal heating soldering iron can be welded.

4, Has a certain mechanical strength: because the strength of tin-lead alloy is higher than the strength of pure tin, pure lead. Because the weight of the electronic components itself is light, the strength requirements of the solder joints of the pcb board maker is not very high, so it can meet the strength requirements of the solder joints.

5, Good corrosion resistance: PCB board maker soldered printed circuit board does not need to apply any protective layer to resist atmospheric corrosion, thereby reducing the technics process and costs.

 

Among tin-lead solders,melting point below 450 ° C is called soft solder. Anti-oxidation solder is a solder used in automated production lines in industrial production, such as wave soldering. When the liquid solder is exposed to the atmosphere, the solder is easily oxidized, which will result in a virtual welding which will affect the welding quality . Therefore, the pcb board maker adds a small amount of active metal to the tin-lead solder to form a coating layer to protect the solder from further oxidation, thereby improving the solder quality.

 

FASTPCBA has been selected as the “excellent partner of the year” by numerous well-known enterprises, and won many domestic and authorized certifications at home and abroad, such as Chinese high-tech project certification, ISO 9001, IATF 16949 quality management system standard and customized CE, UL, FCC and other product certifications according to the customer’s requirements.
