Wave soldering is a crucial soldering process in the electronics manufacturing industry, widely used for Through-Hole Technology (THT) components and some Surface-Mount Technology (SMT) components. Guangzhou Huachuang Precision Technology Co., Ltd. leverages its advanced wave soldering equipment and mature processes to provide efficient and reliable soldering solutions, ensuring high-quality production of electronic products.

The Principle of Wave Soldering

Wave soldering involves creating a wave of molten solder in a solder bath using a pump. When a PCB with inserted or mounted components passes through the solder wave at a specific angle and speed, the solder contacts the component leads and pads, forming reliable solder joints. This process typically includes several key steps:

1. Flux Application: Before soldering, flux is evenly sprayed onto the soldering areas of the PCB to clean the component leads and pads, remove oxides, and enhance solder wetting.

2. Preheating: The PCB enters the preheating zone, where temperatures are controlled between 100°C and 150°C to reduce thermal shock and activate the flux.

3. Soldering: The PCB passes through the solder wave, where the solder wets the pads and leads instantaneously, forming solid solder joints.

4. Cooling: After soldering, the PCB enters the cooling zone, where the solder joints quickly solidify to ensure soldering quality.

Applications of Wave Soldering

Wave soldering is applicable in various electronics manufacturing scenarios, especially in the following areas:

1. Through-Hole Technology (THT) Soldering: Wave soldering is the mainstream process for THT components, suitable for soldering larger components such as connectors, electrolytic capacitors, and transformers.

2. Mixed Assembly: In PCB production that includes both THT and SMT components, wave soldering can be combined with reflow soldering to achieve efficient mixed assembly.

3. Automotive Electronics and Industrial Control: Due to its high reliability and stability, wave soldering is widely used in high-quality-demand areas such as automotive electronics and industrial control.
