The Essence: Controlled Chemical Erosion
At its core, etching is not a mechanical cutting process but a controlled redox reaction that dissolves metal atoms layer by layer. A chemically stable photoresist is applied to protect specific areas, while the exposed metal reacts with acidic or alkaline etchants.
The Role of “Photo”: The Graphic Carrier
Why is it called “Photo” etching? Because the precision of the geometry depends entirely on the UV exposure process. CAD designs are printed on high-resolution film/photo-masks, and light hardens the photoresist through these masks. This avoids the physical wear associated with traditional dies, ensuring the 1st part and the 10,000th part are identical.
Micro-Performance: Double-sided Spray & “Side-Etch”
During processing, metal sheets pass through an etcher where nozzles spray etchant onto both sides simultaneously. Double-sided etching allows the chemistry to meet in the middle to create through-holes. Expert facilities compensate for “undercut” (sideways erosion) by calculating the Etch Factor to ensure final tolerance accuracy.
