The main function of the PCB coating machine is to coat a layer of new materials, such as three-proof paint, UV glue, etc., on the surface of the circuit board to achieve waterproof, dustproof, anti-static and other effects, thereby improving the reliability and service life of the product
Specific functions include coating preparation, coating parameter setting, coating track editing and coating execution, etc.
Working principle
The PCB coating machine precisely controls the coating valve and the transmission track to evenly and accurately coat the coating at the designated position of the circuit board. The entire coating process usually includes the following steps:
Preparation phase: Check whether the equipment components, electrical and air pressure systems, ambient temperature, etc. are normal, and prepare production tools and coatings.
Parameter setting: Set relevant parameters in the equipment software, such as track width, constant pressure barrel air pressure, glue type, etc.
Programming and positioning: Create a new program, edit the MARK point and coating track to ensure that the equipment can accurately identify and locate the coating area of the circuit board.
Coating operation: Start the equipment, transport the circuit board to the designated position through the transmission track, and the coating head performs coating operations according to the preset path.
Finished product output: After coating, the equipment automatically transports the circuit board to the board outlet position to complete the entire coating process
Classification and application scenarios
There are many types of PCB coating machines, including spray, dip and selective coating machines. Spray coating machines use nozzles to atomize the coating material and evenly spray it on the surface of the PCB board; dip coating machines completely immerse the PCB board in the coating material and then slowly remove it; selective coating machines are more advanced, and the coating area is precisely controlled by programming, and only specific circuits, solder joints and other parts that need protection are coated.
These devices are widely used in electronic product manufacturing, communication equipment, automotive electronics, medical equipment and other fields to protect circuit boards and improve the overall performance of products
