Advanced Chemical Etching (A.C.E) has strengthened its management team by recruiting Carwyn Howells and Peter Kirwan as production manager and head of plant and facilities respectively, with the duo key to managing volume increases and capitalising on a PS500,000 investment drive in new inspection equipment and pre and post-cleaning machines.
The fastest way to put a texture onto an injection mold has long been chemical etching. Recent improvements in laser ablation have narrowed the gap.
These kinds of surface finish have traditionally been applied to mould tools using chemical etching, but now the laser is starting to take over to imprint the pattern digitally by ablation.
Textured surfaces have traditionally been executed through the use of grit blasting (also known as sandblasting) alone or in combination with chemical etching. Grit blasting in combination with acid etching is perhaps the most widely used approach today.
Tenibac-Graphion provides of chemical and laser texturing services, such as laser engraving, chemical etching, repair and maintenance, and prototype parts through the Vycon process.
Automated and manual processing lines typically cover processes such as cleaning, chemical etching, electroless plating, electrolytic plating, hard or chromic anodising, tartaric sulphuric anodising (TSA) and conversion coating, such as alocrom or phosphating.
Fabricators use a photographic process followed by chemical etching to obtain the correct pattern of traces on both sides of the panel.
For mass production, there are now three main types of industrial techniques for fabricating DWS mc-Si solar cells: acid texturing with additive [6], reactive ion etching (RIE) [7], and metal-catalyzed chemical etching (MACE) [8-10].
Previously, some coworkers in our laboratories studied the emission spectra that Si-NPs fabricated by chemical etching technique in different organic solvents [12, 18, 19].
Metal-assisted chemical etching (MacEtch) has attracted increasing attention in recent years [1-6].
