The process of SMT chip processing factory of Chinese PCB manufacturers
The process of the SMT patch processing plant mainly includes steps such as solder paste printing, dispensing, patching, curing, reflow soldering, X-RAY inspection, wave soldering, manual quality inspection, cleaning, board splitting and packaging for shipment.
Among them, solder paste printing is to print solder paste or patch glue through the steel mesh onto the pads of the PCB to prepare for the welding of components; dispensing is to drip glue onto the fixed position of the PCB to fix the components. onto the PCB board; patching is to accurately install the surface-mounted components to the fixed position of the PCB; curing is to melt the patch adhesive so that the surface-mounted components and the PCB board are firmly bonded together; reflow soldering is to apply the solder paste Melting, the surface assembly components and the PCB board are firmly bonded together; X-RAY inspection is to detect the components on the PCB board to ensure their correct installation; wave soldering is to solder the PCB board through a wave soldering machine; Manual quality inspection performs manual quality inspection on the PCB board after wave soldering to ensure the welding quality; cleaning is to clean the PCB board and equipment to remove residual dirt and solder; depaneling is to divide the PCB board into different parts so that Subsequent processing; packaging and shipping is to package PCB boards and components into finished products and prepare them for shipment.
In SMT patch processing, it is difficult to fix FPC for high-precision mounting, and it is difficult to ensure consistency during mass production, which requires high equipment. For the fixation of FPC, the entire process from printing and patching to reflow soldering needs to be fixed on a pallet, and the pallet used requires a small thermal expansion coefficient. There are two fixing methods. Method A is used when the QFP lead spacing is above 0.65MM. The pallet is placed on the positioning template. The FPC is fixed on the pallet with thin high-temperature resistant tape, and then the pallet is separated from the positioning template for printing. Method B is used when the QFP lead spacing is less than 0.65MM. The pallet is placed on the positioning template, the FPC is fixed on the pallet with high-temperature resistant tape, and then the pallet is separated from the positioning template for printing. The high-temperature resistant tape used should have a moderate viscosity, must be easy to peel off after reflow soldering, and must have no adhesive residue on the FPC.
