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.

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. 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.

Alkaline Phosphatase | Sigma-Aldrich General description. Alkaline phosphatase catalyzes the removal of phosphate group from various compounds that are phosphorylated. Alkaline phosphatase from calf intestine hydrolyzes 5′-monophosphate groups from both DNA and RNA. It can also hydrolyze 5′-diphosphate and 5′-triphosphate groups from RNA. 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.

Understanding Process Sigma Level | iSixSigma Clarifying Process Sigma and Sigma Level. Sometimes the term process sigma is used instead of the process sigma level, which may cause confusion. Process sigma indicates the process variation (i.e., standard deviation) and is measured in terms of data units (such as seconds or millimeters), while process sigma count Z, or process sigma level, is a count with no unit of measure. USE OF SIX SIGMA METHOD AS A PROCESS IMPROVEMENT TECHNIQUE Atakan Gerger and Ali R1za Firuzan 195 Figure 1. Tube production flow chart and bottle neck To understand of reason of problem and improve of cycle time in alkaline cleaning process, six sigma team was investigated process as details. Alkaline cleaning process consists three steps.
