40um Photoresist Dry Film PCB Making Photosensitive Film Metal Etching Work
It is called Photosensitive film or Photographic film or PCB mask also known as dry film.
Usage: This sheet is mainly used for printed circuit boards (including rigid boards, flexible boards, flexible and rigid composite boards, HDI), lead frames, IC substrates, IC packaging, and other precision etching, electroplating and other industrial image transfer processes.
Application: Just stick it on top of the PCB, it will become a sensitive circuit board. Next, expose the pcb with the film to UV light source (the sunlight for example) and you will have the required tracks impressed on the pcb.

Printed circuit boards are mainly used in products of information technology, communications, automobiles, semiconductors, consumer electronics, etc. Not only do permanent materials such as substrates, interlayer, outermost solder protection and soldered connection materials differ based on the requirements of different products, but the requirements of indirect materials used in the manufacturing process will also be different.
Based on the materials used, process technology and product applications, printed circuit boards can be mainly divided into different products such as Rigid PCB, Flexible PCB, Rigid-Flexible Composite PCB and IC boards. In recent years, because of the rapid development of intelligent products, the trend of various PCB products has accelerated toward compact sizes and high-density circuit layouts. The technical requirements for additional layers of fine lines, pore size and high alignment accuracy are also rising.
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.
