Etch method to minimize hard mask undercut
https://patents.google.com
A method of etching a semiconductor structure is described herein. The method includes providing a hard mask layer covering a substrate, the hard mask layer ...
How Much Do You Know About PCB Solder Mask?
https://jhdpcb.com
When the primer is not fully photopolymerized, increasing the exposure energy can lead to better photopolymerization of the primer, thereby reducing undercut.

https://www.elecfans.com
阻焊层是一种PCB 工艺，用于保护电路板上的金属元件免受氧化，并防止焊盘之间形成导电桥。这是PCB 制造中的关键步骤，尤其是在使用回流或焊槽的情况下。
Solder Mask(SM)是什麼？對PCB有什麼用處？ ...
https://www.researchmfg.com
【Solder Mask】的正確中文名稱應該叫做「阻焊」或「防焊」，因為幾乎99%以上的電路板都採用綠色的阻焊層，所以一般才會俗稱其為「綠漆」或「綠油（大陸 ...

If the minimum values for solder-stop clearance (50μm) and solder-stop bridge (100μm) are undercut, the complete solder-stop bridge is omitted (so-called gang ...
曝光能量於顯像線速搭配達參數固定
https://ndltd.ncl.edu.tw
(4)在與相同油墨、線速、曝光能量下，undercut確有些許差異。初步判定為雖在相同曝光能量、顯影線速下，但無固定印刷參數以致於綠漆厚度不同，導致undercut切片有些差異。
防焊油墨材料
https://www.materialsnet.com.t
印刷電路板疊構最外層為防焊油墨，防焊油墨又叫Solder Mask或Solder Resist。因大部分防焊油墨最常見的顏色為綠色，因此俗稱為綠漆，其他顏色還有藍漆 ...
