Wave soldering is a technique used to solder components on a circuit board by inserting them into molten solder. In wave soldering equipment, the solder is heated to a sufficiently high temperature to form a wave-like “wave crest”. When the circuit board passes over the wave crest, the solder coats the soldering area between the pins and slots, thereby achieving soldering.
Overview of the Soldering Process
The soldering process of wave soldering includes the following stages:
a. Preheating Stage: In this stage, the solder is preheated to the appropriate temperature to ensure thorough melting.
b. Immersion Stage: After preheating, the circuit board is immersed in the solder, and the solder fully covers the soldering area between the pins and slots.
c. Recovery Stage: After immersion, the circuit board is rapidly lifted, causing the solder wave to quickly return to its initial state.
d. Cooling Stage: After soldering is completed, the solder gradually cools and solidifies, forming strong solder joints.
Advantages of Wave Soldering
a. High Efficiency: Wave soldering can solder multiple pins and slots simultaneously, completing large batches of soldering tasks in a short time.
b. Stable Soldering Quality: By controlling the temperature of the solder and the shape of the wave, wave soldering can achieve precise control of soldering quality.
c. Wide Applicability: Wave soldering is suitable for various types of electronic components, including integrated circuits, capacitors, etc.
