Etching treatment manner null of the etching central processing unit of the film carrier tape for electronic parts implementation and the film carrier tape for electronic parts implementation

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for etching process capable of uniform etching in manufacturing a film carrier tape for mounting electronic components, wherein the film carrier tape for mounting electronic components can be transferred in an etching apparatus at a constant speed, the film carrier tape can be left undone in the etching apparatus for a constant time, and the etching procedure can be carried out at a constant pace. ;SOLUTION: The method and the apparatus for film carrier tape for mounting the electronic components is performed for etching continuously fed film carrier tape. The etching process is carried out by travelling the film carrier tape while lubricating liquid is blown out onto the travelling side of an etching plate.;COPYRIGHT: (C)2001,JPO
