A fixture for plasma deglue removal of soft and hard bonded boards to prevent soft areas from being attacked

Abstract

The invention relates to a jig used for plasma deglue and anti-soft zone attack of soft-rigid boards, which includes two FR4 pseudo-substrates with the same size as the production panels of soft-hard boards, and positioning holes are drilled on the pseudo-substrates , and a window is opened on the dummy substrate corresponding to the hard area of ​​the soft-rigid board veneer, the edge of the window covers the center of the soft-hard junction line, and exposes the edge of the hard area of ​​the soft-rigid board veneer; The hard-bonded board production panel is fixed in position by positioning nails inserted in the positioning holes. The invention has the advantages of changing the direct contact area between the gas and the rigid-flex board production panel during the Plasma process, effectively protecting the non-glue-removing area (the position of the soft area), thereby avoiding the impact of Plasma gas on the position of the soft area. attack, and then achieve the purpose of protecting the soft arm.

Description

technical field [0001] The invention relates to a jig used for Plasma deglue-removing anti-soft area of ​​a soft-hard combination board and belongs to the field of printed circuit board processing equipment. Background technique [0002] Before the appearance of printed circuit boards, the interconnection between electronic components was directly connected by wires to form a complete circuit. At the beginning of the 20th century, in order to simplify the production of electronic machines, reduce the wiring between electronic parts, and reduce production costs, people began to study the method of replacing wiring with printing. After that, rigid circuit boards (PCBs) were born and matured. By the middle of the 20th century, flexible circuit boards (FPC) began to rise. The birth and development of PCB and FPC have given birth to a new type of product, the rigid-flex PCB (commonly known as: rigid-flex PCB, Rigid Flex PCB). Rigid-flex board is actually the raw materials of fl...

Problems solved by technology

At present, the traditional plasma (Plasma) glue removal method is to put the entire production panel of the soft-hard bonded board that has been drilled into the Plasma machine to remove the glue residue in the hole. Both the soft area and the hard area are in contact with the Plasma gas. Plasma gas needs to be in contact with the drilled holes on the hard area, and the unnecessary contact surface (soft area position) will be damaged by the attack of Plasma gas, which will affect the subsequent process and product quality
