Wave Soldering & Selective Soldering

 

The Importance of Wave Soldering and Selective Soldering in THT Line Assembly

Wave Soldering & Selective Soldering are essential pieces of equipment in the (Through-Hole Technology) THT Line. The THT Line plays a crucial role in the assembly and manufacturing of electronic devices, where components with leads are mounted onto PCB through holes drilled into the board. This technology is indispensable in various industries, including automotive, aerospace, consumer electronics, and telecommunications, where reliability and durability of electronic assemblies are paramount. The precision and efficiency provided by wave and selective soldering machines ensure high-quality solder joints, making them vital for the production of robust electronic products.

DIP Line in Electronics Manufacturing

The DIP Line is an indispensable production line in the electronics industry. It includes essential soldering equipment such as wave soldering machines, selective soldering machines, and flux spray machines.

Additionally, the line features manual insertion lines and fully automatic insertion lines. To ensure the quality of DIP component soldering, Automated Optical Inspection (AOI) is also incorporated.

The Role of THT Line in Electronics Manufacturing

In the electronics field, the THT Line is one of the indispensable production lines. Typically, it is preceded by a SMT production line and followed by a Conformal Coating Line. In modern electronics, the SMT production line has not replaced the THT production line despite the miniaturization of components. This is because of the essential DIP (Dual In-line Package) components that require through-hole mounting. The normal production process involves the SMT production line first, followed by the THT production line, and finally, the Conformal Coating Line, which applies a protective coating to enhance the longevity of the PCBA (Printed Circuit Board Assembly).

Stage 1: SMT Placement

In the first stage, components are mounted directly onto the surface of PCB using automated machines with high precision and speed.

Stage 2: DIP Assembly

Components with leads are inserted into drilled holes on the PCB and soldered, providing strong mechanical bonds and high reliability.

Stage 3: Glue Spraying

A protective coating is applied to the assembled PCB, enhancing durability and longevity by shielding it from environmental factors.
