Process description Alkaline Mecer | Sigma Group Using a process known as solvent extraction or liquid ion exchange, a portion of the copper is transferred out of the etchant into an organic extractant. Process Description Alkaline Mecer Sigma Group Equipment For Copper Recycling And The regenerated etchant is then sent back to storage for reuse in the etcher. The organic is passed on to the next step in the solvent extraction process. Home | Sigma Group - Equipment for copper recycling and Welcome to Sigma.

alkaline phosphatase | Sigma-Aldrich Phosphatase, Alkaline from human placenta. Summary: There are at least four distinct but related alkaline phosphatases: intestinal, placental, placental-like, and liver/bone/kidney (tissue non-specific). The intestinal alkaline phosphatase gene encodes a digestive brush-border enzyme. SIGMA | all4-PCB all4-PCB is a proud distributor of Sigma. The Sigma Group stands for engineering with experience for more than 25 years. With the headquarters in Karlstad, Sweden, their product portfolio contains equipment for on-site recycling of alkaline and acidic etching solution. Equipment from Sigma has a short payback period (usually 6-18 months.

WE DESIGN FOR THE FUTURE MECER The MECER process for alkaline etching During the etching process of printed circuit boards, the etchant becomes increasingly loaded with copper. Opti-mum etching performance is achieved when the copper concentration of the etchant is between 140-160 g/l with an equivalent amount of chloride ion and some free am-monia. WE DESIGN FOR THE FUTURE MECER - h24-files.s3.amazonaws.com latest years Sigma Engineering AB has developed the recovery sys-tem for acidic cupric chloride etchant called the acidic MECER. This process is quite similar to the alkaline MECER, on the market since 30 years, also using solvent extraction and electrowinning techno-logy. All the basic closed circuit concepts are essentially the same.

Calculating the Sigma Level - MoreSteam.com Calculating the Sigma Level. The Sigma Level provides a high level baseline metric to understand the capability of a process (or entire organization) to meet customer requirements. When calculating the Sigma performance level for a product or process, the metric Defects Per Million Opportunities (DPMO) is generally used. When is it used?. Sigma Level — DMAIC Tools Sigma Level. Process sigma (also referred to as sigma level) is a measure of process capability: the higher the process sigma, the more capable the process is. A Six Sigma process has a short-term process sigma of 6, and a long-term process sigma of 4.5 (see why not 4.5 sigma? ). The theoretical defect rate for a Six Sigma process is 3.4.
