What are the technological processes of PCBA processing and assembly?
PCBA processing assembly is to assemble various electronic components on the PCB board through the surface packaging process. The PCBA process flow mainly includes the SMT process and the DIP process. Due to the difference in the size of the electronic components, there will be Different process requirements, so what are the PCBA processing and assembly process?
The PCBA assembly process and process mainly depend on the assembly components and assembly equipment conditions, which can be roughly divided into several common component assembly such as single-sided mounting, double-sided mounting, single-sided mixed assembly, and double-sided mixed assembly processes.
Single-sided mounting process:
The single-sided mounting process means that the components are all mounted components, and the components are only affixed to one side of the pcb board.
The main process flow of single-sided mounting: incoming inspection-printing-patch-reflow soldering-cleaning-inspection
Single-sided mixed packaging process:
The single-sided mixed assembly process means that the components are both mounted and plug-in units, and the components are only mounted on one side of the PCB board.
The main process flow of single-sided mixed assembly: incoming inspection-printing-patch-reflow soldering-cleaning-plug-in-wave soldering-cleaning-inspection
Double-sided mounting process:
The double-sided mounting process means that the components are all mounted components, and the components are mounted on both sides of the pcb board.
The main process flow of double-sided mounting: incoming inspection-PCB board A side printing-SMD-reflow soldering-flipping-PCB board B side printing-SMD-reflow soldering-cleaning-inspection
Double-sided mixed assembly process:
The double-sided mixed assembly process means that the components are both mounted and plug-ins, and the components are mounted on both sides of the pcb board.
Double-sided mixed assembly process: incoming material inspection-PCB board A side printing-patch-reflow soldering-PCB board B side plug-in-pin bending-flip board-B side patch glue-patch-drying- Turnover-wave soldering-cleaning-inspection
The above is a simplified version of the PCBA processing and assembly process. Due to the complex PCBA processing and assembly process, each production link is very important. Therefore, when choosing a PCBA processing and assembly plant, the production and assembly capabilities of the processing plant should be assessed.
