What is Prototype PCB Assembly?

To put it simply, the PCBA Manufacturing process is a combination of SMT processing and DIP processing. According to the requirements of different production technologies, it can be divided into single-sided SMT placement process, single-sided DIP insertion process, single-sided mixed packaging process, and single-sided mounting process. Mounting and inserting mixed process, double-sided SMT mounting process and double-sided mixed process, etc.
Different types of PCB boards have many different processes. The differences will be explained in detail below for various situations.

1. Single-sided SMT mounting

The solder paste is added to the Electroniccomponent pad, after the solder paste printing of the bare PCB is completed, the relevant electronic components are mounted through reflow soldering, and then reflow soldering is performed.
The Turkey PCB Assembly process involves processes such as carrier board, printing, patching, reflow soldering, plug-in, wave soldering, testing and quality inspection

2. Single-sided DIP cartridge

The PCB board that needs to be plug-in is wave soldered by the production line workers after inserting the electronic components, and after the soldering is fixed, the feet can be cut and the board can be washed. However, the production efficiency of wave soldering is low.
3. Single-sided mixed

The PCB board is printed with solder paste, and the electronic components are mounted and fixed by reflow soldering. After the quality inspection is completed, DIP insertion is performed, and then wave soldering or manual soldering. If there are few through-hole components, manual soldering is recommended .
4. Single-sided mounting and plug-in mixing

Some PCB boards are double-sided, one side is mounted and the other side is inserted. The process flow of mounting and inserting is the same as single-sided processing, but the PCB board requires the use of fixtures for reflow soldering and wave soldering.
5. Double-sided SMT mounting

In order to ensure the aesthetics and functionality of the PCB board, some PCB board design engineers will adopt a double-sided mounting method. IC components are arranged on side A and chip components are mounted on side B. Make full use of the PCB board space to minimize the PCB board area.
The above only simplifies the PCBA assembly process of the printed circuit board, and demonstrates its manufacturing process in a graphic manner. However, as the PCBA assembly process and production process are gradually optimized, the failure rate is also continuously reduced, ensuring the production of high-quality finished products. The solder joint quality of all the electronic components mentioned above determines the quality of the PCBA board。
