Chemical & Mechanical Treatment

Chemical and mechanical treatment may be employed to enhance the surface and properties of the substrate which requires a comprehensive range of process.

Wet chemical processes for lithography development, etching and stripping are used in PCB as well as in display and touch panel production. Wet processes are also very important, in photovoltaic production etching. Our system covers all these important process steps and also includes wet chemical processing equipment for reworking, cleaning, immersion, bond film and preservation.



For chemical process like etching which can be applied onto different type of substrate, we offer various processes such as caustic and organic process.

Mechanical treatment is equally important to achieve smooth and even surface for downstream process. Our systems are designed with specially fabricated brushes to remove even the smallest particle of burr.

Applicable in PCB, touch panel, LED, photovoltaic, semi conductors, automotive, general metal finishing and IC substrate.

At NICA we provide total and customized solutions to cater various steps of manufacturing to help our customer achieve their desired product quality and output.
