What is Dry Film
Dry film is a type of photosensitive material used in the manufacturing process of printed circuit boards, which serves as a protective layer that is applied to the surface of the PCB to create circuit patterns. Dry Film is typically available in a blue color and can be obtained from various manufacturers and distributors, either online or in specialized shops.
Dry film is easy to use in the PCB manufacturing process. It does not interfere with the holes on the board, allowing for its application without causing any damage or obstruction to the necessary holes for component placement and soldering. Dry film is particularly suitable for higher density circuit designs, where intricate and complex circuit patterns with numerous components and traces packed closely together are required.
Dry Film may have limitations in terms of resolution, potentially resulting in reduced detail and precision in the circuit patterns compared to other methods. Scratches or bubbles can sometimes occur during the application process, which, if not properly addressed, may lead to circuit defects. Additionally, Dry Film tends to be more expensive than alternative methods, which may impact overall manufacturing costs.
