This article will explore the soldering technology in PCBA processing in depth, including its significance, common soldering methods, importance and application practices, aiming to provide readers with a comprehensive understanding and guidance.

The significance of soldering technology

1. Connecting circuits

Soldering technology can firmly connect electronic components to PCB (Printed Circuit Board) to form a complete circuit.

2. Ensure electrical connection

Soldering can ensure the stability and reliability of electrical connections and prevent circuit failures caused by poor contact.

3. Improve product reliability

Good soldering quality can improve product reliability and stability, reduce failure rate and extend product life.

Common soldering methods

1. Surface mount soldering (SMT)

Use solder paste to paste components on the PCB surface, heat them with hot air or hot plate, and melt the solder paste to connect with the PCB pad.

2. Wave soldering

Place the PCB board in the solder wave so that the solder liquid contacts the PCB pad to achieve solder connection.

3. Manual soldering (PTH)

Manually solder electronic components to the pads on the PCB board through solder wire or solder bar, suitable for small batch production or special components.
