The mounting of components refers to attaching built-in components to intact solder paste (or surface mount adhesive)pcbAt the corresponding positions on the surface layer of the board, a laminating machine is used. So, how many ways are there to mount components? Shenzhen JJYSolder paste manufacturerLet's inform our partners:
When applying the lamination machine, its advantages and disadvantages are reflected in the packaging and printing of the equipment, large volume, short delivery time, sufficient budget, batch production, relatively good manufacturing performance, complex application process and large investment.
Manual packaging printing. Medium and small-sized mass production, new product development The actual operation is simple, the cost is low, and the productivity depends on the actual staff's mastery of the operation. The tools for manual mounting include vacuum suction pens and medical tweezers.ICAspirator, low-magnification microscope or magnifying glass.
Reflow soldering. whenpcbCircuit board, when heating the temperature zoneSolder pasteThe organic solvents in it have evaporated. In addition, the solder paste will soften when heated and cover the solder pad, isolating the pad, component pins and oxygen, allowing surface mount components to be fully heated before entering the soldering area.
At this moment, liquidSolder wireinpcbWhen the solder pads, component soldering ends, and pins are moist, diffused outward, and reflow mixed on the soldering surface, they will be transformed into metal compounds. After generating solder wire contacts,PCBEnter the refrigeration zone to cause the spot welding to solidify.
Shenzhen JJYCarry out mutually beneficial cooperation with electronic raw material producers, and also produce solder paste, flux paste, lead-free solder paste, solder wire and solder bar for other enterprises. With a rich variety of successful cases in the research and development of chemical raw materials, our overall strength has created a sales market that is of high quality and honest and trustworthy.
