Description

Multilayer soft board and soft or hard board trimming die utensil

Technical Field

The utility model relates to the field of circuit board manufacturing, in particular to a multilayer soft board and soft and hard board trimming die.

Background

FPC flexible wiring boards are one of the major types of printed circuit boards. According to the structure of the FPC, the FPC can be divided into a single panel, a double-sided board, a multilayer board and a rigid-flex board according to the number of conductor layers. Printed circuit boards are basic products in the electronics industry, are widely used in electronic products such as communication equipment, computers, automotive electronics, industrial equipment, various household appliances and the like, and have the main function of supporting circuit elements and interconnecting circuit elements.

The multilayer circuit board is produced through the first making inner layer core board comprising double-sided copper foil and single-sided copper foil, the subsequent superposing other single-sided or double-sided boards, adding adhesive, heating, pressurizing and adhering to form multilayer board. The soft and hard combined board belongs to the category of multilayer boards and is formed by laminating copper foil materials, covering films, PP sheets, FR4 copper clad plates, pure copper foils and other materials at high temperature and high pressure.

Due to the fact that the number of layers of the materials is large, in the pressing process, due to the tolerance of fitting or pressing sliding, the edges of the boards and various materials are uneven, a plurality of gaps exist, and PP or FR4 residue crushed aggregates generate huge hidden dangers such as the quality of subsequent production. For example, the residue scraps at the plate edges can be adhered to equipment in the production process and other plate surfaces produced in the same line; the liquid medicine falls into the liquid medicine tank through which the liquid medicine is polluted, and the liquid medicine can be adhered to other board surfaces produced on the same line, so that the hidden quality trouble which is not easy to perceive can be generated. And various liquid medicines can be adsorbed in gaps of the plate edges, so that the plate cannot be cleaned and dried, and cross contamination and oxidation which is difficult to remove are generated when the plates are folded and stacked.

Therefore, trimming is a necessary process to improve the yield of the multi-layer board. The common practice in the industry is manual cutting and die cutting.
