Used ALL4-PCB 455-CdCl #9262328 for sale

ALL4-PCB 455-CdCl is a photoresist equipment designed for the production of printed circuit boards (PCBs). It is comprised of an alkaline resist formulation, a photoinitiator and the CdCl2 charring agent. The combination of these components allows for excellent resolution patterning of interconnects for the production of circuit boards. The Alkaline Resist formulation has a low etching rate for copper and has excellent photosensitivity. The presence of the photoinitiator further increases the molecular crosslinking of the resist layer, allowing for improved wet etch and lift-off performance. Additionally, the photoinitiator serves as the light-activated trigger in the imaging process. The CdCl2 charring agent serves as the main etching component of the resist. It helps with the removal of unwanted copper traces based on the differential etching rate between the resist and the copper. When exposed to light, the charring agent reacts with the alkaline resist formulation leading to a cross linked resist layer, thus forming a pattern in the resist layer. There are several advantages associated with ALL4 PCB 455-CdCl when compared to other photoresist systems.⁠ The etch rate is very high allowing for precise and fine patterns on high aspect ratio structures. Also, the resist layer locks well, giving improved adhesion of the final product. Finally, the system is compatible with multiple types of PCBs and is widely used across different industries. The ALL4 PCB ALL4-PCB 455-CdCl photoresist unit requires strict safety protocols due to the hazardous and volatile nature of the chemical components. Care must be taken when mixing, handling and disposing the resist mixture. The user should wear appropriate protective clothing and regularly check on the disposal regulations for the particular country. In conclusion, the ALL4 PCB 455-CdCl photoresist machine provides excellent resolution and etching performance for the production of printed circuit boards. The presence of the photoinitiator and charring agent in the resist layer allow for splinter free patterns and improved adhesion. It is important to follow all safety protocols when using this tool due to its hazardous nature.
