4170-500ML产品概述
MG Chemicals' negative film is a photosensitizing material that can easily be applied onto plain copper boards by using a standard laminator. Once applied, you are ready for exposing, developing and etching. Negative Developer is required. With the Negative resist, everything exposed to light will remain during the development process. For that reason, the schematic printed onto the transparency for the negative process is reversed compared to that of the positive print out. The unexposed color is green. The exposed color is blue. The negative developer is used to remove exposed resist during the positive photofabrication process.
