Ultrasonic Spraying Photosensitive Ink in PCB Board

Ultrasonic Spraying Photosensitive Ink in PCB Board – Cheersonic

Photosensitive ink is a special ink with photosensitive properties. It is composed of photosensitizer, resin solvent, etc., among which photosensitizer is the key component. Sensitizers can absorb light of a specific wavelength and react chemically under the action of light, thereby changing the chemical properties of the ink.

The working principle of PCB photosensitive ink is based on the chemical reaction of light. When a part of the area sprayed with photosensitive ink is exposed to light of a specific wavelength, the photosensitive agent will absorb the energy of the light, resulting in a chemical reaction. This chemical reaction will cause the physical properties of the photosensitive ink to change from soluble to insoluble, and all sprayed photosensitive inks will be divided into soluble plates and insoluble plates. Then through the development process, only the insoluble part is retained on the circuit board to form the desired circuit pattern.

Ultrasonic spraying photosensitive ink has the following advantages:

High uniformity: Ultrasonic spraying photosensitive ink can form a layer of uniform thickness and dense photosensitive coating on the surface of the substrate, which greatly improves production efficiency and product quality.

Low cost: During the ultrasonic spraying process, the waste of raw materials caused by ink splashing is greatly reduced, and the manufacturing cost is reduced.

Environmentally friendly: Ultrasonic spraying equipment has exhaust gas treatment during spraying, and compared with traditional spraying, there is no risk of liquid splashing, reducing environmental pollution, and waste is easy to recycle.

Relatively stable and reliable: The working state of ultrasonic spraying photosensitive ink is relatively stable, which can ensure the yield rate of the manufacturing process.
