Photosensitive etching: the technology belongs to the field of photosensitive chemistry technology, which is a method of using photolithography corrosion and thin precision metal products.
Silk screen etching: in short, it is to use the method of screen printing to print corrosion-resistant printing ink on the metal plate to be etched, and then use chemical or electrolytic etching to remove corrosion. What are the specific differences between them?
The difference between photosensitive etching and silk screen printing
Advantages and characteristics of photosensitive etching:
1. Will not rust, long service life;
2. Light weight;
3. High end feeling;
4. There are differences between brushed and bright surfaces;
5. Metal texture;
6. Strong sense of solemnity;
Advantages and characteristics of silk screen etching:
1. Reaction solution and deionized water that require high cost budget;
2. Safety risks encountered by workers during chemical treatment;
3. Photoresist adhesion;
4. Incomplete and uneven etching caused by bubble formation and the failure of chemical etching solution to completely contact the surface layer of the crystal state; Exhaust gas and potential explosion.
It is worth noting that the transfer edge is beautiful and sawtooth free when processed with photosensitive ink, while the transfer edge is sawtooth when printed with silk screen. In addition, in terms of cost budget, photosensitivity will be more expensive than silk screen printing, which is suitable for small batch fine production, and silk screen printing is suitable for large-scale low-cost production.
