Conformal coating to protect the mounting board (PCB)
Case study maskless coating
Issues
- Due to manual brushing, the quality of the product depends on the skill of the worker.
- The highly difficult varieties can only be handled by specific skilled workers.
- Therefore, if a worker suddenly rests due to COVID-19 infection, the production volume will be limited.
- For varieties with no application areas, masking materials are pasted and then brushed, which takes time.
- We are concerned about worker health problems due to volatile compounds (VOCs) contained in liquid chemicals.
Measures
- Introduced semi-automatic application system and Fully automatic dispensing machine using Desktop robot.
- Double-use JET Dispenser and coating valve for the dispense head.
- In order to improve the environment, we introduced a safety cover with intake and exhaust system.
Effect
- Regardless of the skills of the workers, no matter who is in charge, a high quality finish was achieved, and the good quality ratio increased.
- With JET dispense, "maskless coating" can be performed, reducing the masking process. Productivity has improved.
- In areas with a large application area, curtain coating is performed using a coating valve. We tried to shorten the tact.
- The workers can be isolated from the volatility of the liquid agent, eliminating the need for health problems.

Case of Other
Filling Chemical solution for screw cap tubes, conical tubes and vials, and semi-automated cap opening and closing operations.
Liquid metals are being used in the CPU Heat dissipation of high-performance gaming PCs. Achieving high speed and stable application with non-contact Jet dispense.
A thermal management solution that supports new technologies such as next-generation power semiconductors, 5G, and IoT.
It is fast, there is no contact accident with the workpiece, and can be applied from lower, horizontal, or diagonally.
There is no problem even if there is a different distortion or warpage in each workpiece, or if the workpiece is shifted in the pallet.
