Metal etching process-control guide covering chemistry, temperature, agitation, time, masking, material condition, defect prevention and inspection.
I am Jody Zhang, I graduated from Wuhan University in 2000. I am an automation engineer with 24 years of experience, in charge of writing content for Xinketching. I am willing use my experiences to create reliable and necessary metal etching information to help our readers. We welcome readers to engage with us on various topics related to metal manufacturing. Please feel free to share your thoughts and questions on these subjects with us. We look forward to hearing from you!
The Scratching Method for Creating an Anti-Etching Layer: A Detailed Guide
Etching is a subtractive manufacturing process used to selectively remove material from a substrate using chemicals, plasma, or other agents. A critical component of etching is the anti-etching layer ( or resist) , which protects specific regions of the material from being etched. The scratching method is a manual, low-tech technique historically used to pattern this protective…
Alkali-Resistant and Corrosion-Resistant Materials in Etching Technology: A Comprehensive Guide
Etching technology, pivotal in industries like semiconductors, printed circuit boards (PCBs), and metalworking, involves removing material layers using chemicals or plasma. The process demands materials that withstand harsh environments, including alkalis ( e.g., NaOH, KOH) and corrosive agents (e.g., acids, plasmas). This article explores materials resistant to these conditions, their applications, and selection criteria. Corrosive…
The Essential Requirements for Anti-Etching Layers in Etching Processes
In microfabrication and semiconductor manufacturing, the anti-etching layer ( or etch mask) is critical for selectively protecting regions of a substrate during etching. This layer must meet stringent requirements to ensure precise pattern transfer, durability, and compatibility with complex processes. Below, we explore the key requirements for effective anti-etching layers, material considerations, and process integration…
