Understanding the Basics of PCBA Assembly

Strong mechanical connections are essential to withstand external forces, prevent components from shifting, and contribute to effective heat dissipation. Electrical connections are essential to establish proper circuit function. Enables signal and power flow between different components on the PCB, ensuring seamless operation. Precise electrical connections minimize signal loss, impedance mismatch, and noise interference to optimize the performance of electronic devices.

PCBA assembly using Through-hole technology (THT) A technique in which pins of electronic components are inserted into pre-drilled holes in the circuit board and then welded. More complex and time consuming than surface mount technology (SMT), it can provide stronger mechanical connections and is particularly suitable for handling large, heavy or high-power components. The pin of the electronic component is inserted into the hole on the circuit board using professional equipment, and the component is fixed to the circuit board using wave soldering technology. In this process, the board is sent over a crest containing molten solder, which allows the solder to flow along the pin of the component and cool to solidify, creating a solid solder joint. SprintPCB's THT technology enables us to handle a wide range of complex and challenging PCBA assembly projects. Our professional team is committed to providing the highest quality service to meet all the needs of our customers.

PCBA assembly using a hybrid technology of surface mount technology (SMT) and through-hole technology (THT), this hybrid technology takes full advantage of the respective advantages of SMT and THT to handle a variety of complex and challenging PCBA assembly projects. SMT is used first to mount small and lightweight electronic components onto the circuit board. Use THT to insert large, heavy, or high-power components onto a circuit board. SprintPCB's hybrid SMT and THT technology enables us to provide high-quality, efficient and reliable PCBA assembly services. Our professional team is committed to providing the highest quality service to meet all the needs of our customers.

Mechanical and electrical connections ensure the physical stability of electronic components on the board during PCBA assembly, while electrical connections ensure correct communication between electronic components. High-precision equipment is used to place the electronic components onto the board, and next, advanced welding techniques are used to secure the components to the board. Tests are carried out, electrical tests, functional tests and visual inspections to ensure that the circuit board can work properly.
