.Hole type : through hole, vertical through hole, conical through hole (loud-speaker type), center step through hole or edge step  parts
chemical etching technology index:
1. the smallest size: round hole 0.1mm, rectangular hole 0.15mm, smallest 0.02mm (interval)
2. largest area of processing: 580 * 750
3. processing plate thickness: 2MM - 0.05MM (especially suitable for below 0.5mm of the foil board).
4. Graphic positioning accuracy: ± 0.01mm

Uses: widely used in petroleum, chemical industry, food, fruit juice machine mesh, soya-bean milk machine mesh, sophisticated filters for medicine, filter plates, filter cartridges, filters; electricity industry use metal plate leakage, flat, flat pin, Lead frame; optical precision machinery and plane parts, spring parts, mobile phone parts

Compared with machinery and punching and laser drilling, product has the following features:
1. It is no limit for complex geometric patterns . No matter how complicated shape or pattern forming process, do not need increase production cost.
2. Chemical etching is a double-sided processing technology, product surface is smooth, non-protruding, pit-free, glitch-free, non-warping, distortion-free mesh formation.  It is no need grinding, polishing, after the self-pressure process.
3. Processing fine size (round below 1MM , line width 0.02MM), uniform positioning accuracy (± 0.01MM).  
4. Short production cycle, quick response, designed to facilitate revision.
