Due to the widespread use of smartphones, touch panels have become the mainstream of current smartphones and tablet. For both glass and film capacitive touch, the requirements of the lithography and etching processes for ITO lines are more and more precise. Eternal's dry film photoresist provides film capacitors with the best solution for automatic roll-to-roll production and fine line making.
Dry film photoresist is the key component used in the image transfer process. It is widely used in precision etching and electroplating products such as Printed Circuit Board (including Rigid board, Flexible board, Rigid/Flexible composite board, and HDI), Lead Frame, IC Substrates, IC packaging, etc. With strong in-house R&D capabilities, we are able to design and develop dry film products to specifically match our customers' requirements for various processes such as Chemical Milling, Electroforming, etc.
