Introduction of Photoresist Classification Introduction of Photoresist Classification - Deposit Photoresist - Cheersonic 1. Classification by application field Photoresists are classified by application fields and can be divided into PCB photoresists, display panel photoresists, semiconductor photoresists and other photoresists. In the PCB industry: the main photoresists used are dry film photoresist, wet film photoresist, photosensitive solder resist ink, etc. The dry film is pasted on the treated copper-clad [...]

Megasonic Cleaning Systems Megasonic energy is currently a very widely used cleaning method. After adding megasonic energy, the use temperature and process time of the solution can be greatly reduced, and the cleaning effect is more effective. The commonly used frequency of megasonic cleaning is 800kHz-1 MHz, and the megasonic power is 100-600W. Compared with ultrasonic cleaning, the effect of megasonic cleaning is [...]

Photoresist Composition Photoresist Composition - Deposition of Thin Photoresist Films - Cheersonic Photoresist is a mixed liquid that is sensitive to light. Its components include: photoinitiators (including photosensitizers, photoacid generators), photoresist resins, monomers, solvents and other additives. Photoinitiators (including photosensitizers, photoacid generators): Photoinitiators, also known as photosensitizers or photocuring agents, are a type of energy that can absorb a certain wavelength from light (usually ultraviolet light). Photochemical reactions [...]

Semiconductor Packaging Semiconductor Packaging - Semiconductor Coating Systems - Cheersonic A wafer that has been processed through the previous processes results in square chips of equal size (also known as "single wafers"). The next thing to do is to get the individual chips by dicing. Freshly cut chips are fragile and cannot exchange electrical signals, and need to be handled separately. This process is encapsulation, which involves forming [...]
