Micromachining using electrochemical discharge phenomenon spark assisted chemical engraving is based on electrochemical discharges generated in a gas film around an electrode as described in chapter 2 design and use of micromachining chemical micro drilling or chemical engraving techniques and equipment. Micromachining using electrochemical discharge phenomenon second edition fills this gap it is unique in its detailed coverage of all aspects of the micro ecdm process as well as spark assisted chemical engraving sace. This chapter discusses the process of glass microdrilling by using the spark assisted chemical engraving sage technique during sage the heat source produced by the electrochemical discharges has to be close to the workpiece typically a maximum distance of 25 um from the workpiece is required in the case of glass.
