Printed Circuit Board Industry

Dry Film Photoresist:

The global Printed Circuit Board (PCB) Market is expected to reach an estimated $89.7 billion by 2024. Emerging trends, which have a direct impact on the dynamics of the PCB industry, include miniaturization of printed circuit boards, growing demand for high speed data and signal transmission, and development of green PCBs.

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.

Soldermask:

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 Solder Mask is a permanent material mainly used for circuit protection on the outer layer of Flexible/Rigid printed circuit boards, IC substrates and other rigid boards. Eternal is well equipped to meet customers' special application requirements.
