Used TEL / TOKYO ELECTRON ACT 12 #9281482 for sale

TEL / TOKYO ELECTRON ACT 12 is a photoresist etching equipment used in the fabrication of printed circuit boards (PCBs). This system utilizes positive photoresist to etch away the unwanted parts of a PCB circuit pattern. TEL ACT 12 photoresist unit increases the accuracy and repeatability of the etching process, resulting in improved product quality and reduced production costs. TOKYO ELECTRON ACT12 machine consists of a high-resolution photoresist product and specialized apparatus. The photoresist product contains polyphenylene sulfide (PPS) particles suspended in an alkali-stable benzene resistance material. These particles are melted onto the substrate, creating a highly resistive film which is resistant to etchants and acids used in PCB fabrication. The specialized apparatus consists of a slit-pattern writing mask and a high-resolution laser light source. This apparatus is used to draw the precise slit pattern on the photoresist layer. Once the slit is drawn, the photoresist is developed, which removes exposed areas and leaves the desired PCB circuit patterns. To ensure accuracy in the development process, ACT 12 tool implements a 'critical dimension control' feature. This feature uses advanced inkjet printing technology to monitor and adjust the pattern without stopping the etching process. Additionally, the asset uses an on-board computer to perform image processing, allowing for automatic control over the etching process. Another advantage offered by ACT12 model is its low resistivity. This reduces the current leakage in the circuit patterns, resulting in improved electrical properties in the PCBs. Finally, the equipment is cleanroom compatible, with an electric cabinet that can be used to prevent any dust generated during the etching process from entering the photoresist system. All of these features make TEL ACT12 unit an ideal choice for fabricating high-quality, precision printed circuit boards.
