Regarding photo-etching
Photo-etching technology is (separately called Photo Etching/Chemical Milling) a technology to cut and process metals by combining corrosion resistance masking that applies precision photographic technology and chemical cutting through the chemical reaction and corrosive action of metals. It is a dedicated technology that can respond to a precision process of ultra-small, ultra-thin and complicated shapes used in the electronics field, as well as a variety of other fields such as optics, electrics and electronics.
1. Technological characteristics of photo-etching
* Possible for ultra-fine, high density, complicated and ultra-small processing
* Possible to process the sheet thickness of a material, enabling grooving in an arbitrary shape, or process a protruding shape within the sheet thickness.
* No change in material occurs and no burrs, bends or deformation of a product occurs due to processing.
* Expensive mold or jig tools are not required, resulting in a drastic reduction in initial investment, as well as a reduction in delivery time.
* Possible to respond to time sensitive deliveries and small lot production runs. (Shortest delivery and lot: One day/one piece)
2. Processable materials:
Steinless / Copper / Copper alloy / Brass / Nikkel silver / phospher Bronze / Steel / Special steel / permalloy / other secial alloy
SUS, steel materials, special steel, carbon steel and permalloy
Non-ferrous metal (Copper, copper alloy, brass, albata, phosphor bronze)

Special materials and difficult-to-process materials (titanium, magnesium, etc.) are also available. Please contact us directly.
3. Sheet thickness to be processed
t=0.005mm-Max1.5mm

Bridge shape
During the etching process, the product needs a junction (bridge). An appropriate shape must be planned depending on sheet thickness and shape.
