Dry-film Processing
  1. Kindly advise me regarding the lighting conditions required when laminating dry-film photopolymers. Specifically, what type of ambient lighting is allowed? For example, can I expose the film to normal indoor lighting, red safe light, yellow or green light? Does the film require a room that is completely dark?
  2. Is there a quick test to see if there is too much UV light in my work shop?

Soldermask
  1. I am using a dry-film soldermask for my PCB boards. The cured color is yellowish-green and the finish dull. On production boards that we buy, the soldermask is dark green and has a glossy finish. Is this really the color of the dry-film soldermask or there is something wrong with my process?
  2. I am working on a lab-scale hot roll laminator. Following the manufacturer's specs for laminating their dry film photoresist to a circuitized board, I have observed some bubbles which look to be trapped against the copper circuitry. Have you ever observed this kind of behavior? How can I get a bubble-free lamination?
