Title: Method for etching metallic thin sheet
Inventor: SATO MANABU
IPC: C23F1/00
Filed: 1992-04-28
Abstract: PURPOSE:To remarkably reduce the defective deformation after etching by controlling the half etching depth and forming a shallow half-etched part having a smooth cross section. CONSTITUTION:A resist R is firstly applied on a metallic thin sheet except the part (d) to be half-etched and the part (f) to be penetration-etched. The parts (d) and (f) are etched to about 0.05mm depth to form a half-etched part D and quasi penetration-etched parts F1 and F2, and the resist R is released. Although a resist E is secondly applied by a roller coater, etc., the resist E is applied on the recessed half-etched part D by a brush. The second etched part is finally pierced to form a pierced part F, and the resist E is removed to work a lead frame to a specified size.
