The coating machine pre-dots a special glue on the PCB board where the patch needs to be mounted, and then passes it through the oven after curing. Coating is carried out automatically according to the program. The coating machine is mainly used to accurately spray, coat and drip the conformal coating, UV glue and other liquids into the precise position of each product in the product process. It can be used to draw lines, circles or arcs.
It is widely used in: LED industry, driving power industry, communication industry, computer motherboard, automation industry, welding machine industry, automotive electronics industry, smart meter industry, electronic components, integrated circuits, circuit board electronic parts fixation and dust-proof and moisture-proof protection wait.
It has four major advantages over traditional coating processes:
(1) The spray paint amount (coating thickness accuracy is 0.01mm), spray paint position and area (positioning accuracy is 0.02mm) are accurately set, and there is no need to add people to wipe the board after painting.
(2) For some plug-in components with a large distance from the edge of the board, they can be painted directly without installing fixtures, saving board assembly personnel.
(3) There is no gas volatilization, ensuring a clean working environment.
(4) All substrates do not need to use clamps to cover the carbon film, eliminating the possibility of collisions.
According to the continuous development of technology in the coating equipment industry, products that need to be coated can be selectively coated. Therefore, selective automatic coating machines have become the mainstream equipment for coating;
According to the needs of actual applications, the size of the coating machine needs to be miniaturized while ensuring the effective coating area to meet the production site.
