Protective Member Shields Terminals During Plate Workpiece Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plate-shaped workpiece processing methods risk damaging terminals during the cutting process due to the use of holding jigs or tapes, which can cause mechanical stress or contamination, leading to terminal defects.
Innovation Solution
A method involving a protective member with an adhesive layer is applied to the workpiece to cover the terminals, allowing for secure holding without direct contact with the holding jig or tape, and subsequent peeling without damage, while forming V grooves and conductive shield layers to protect and process the workpiece effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a holding jig or holding tape is used to hold the back side of the workpiece where terminals are provided, then the workpiece can be securely held during cutting, but the terminals may be damaged by the holding jig or holding tape
Solution Approach 1:
A protective member is introduced as an intermediary between the holding jig/holding tape and the terminals. The protective member has a first surface that contacts the holding device and a second surface that faces the terminals, creating a buffer zone that prevents direct contact and potential damage to the terminals while maintaining secure workpiece holding during cutting operations
2Stability of the object's composition
If the front side of the workpiece is held by a jig or tape during cutting, then the workpiece can be securely held, but the terminals exposed on the back side may be damaged by cutting dust or contamination
Solution Approach 1:
The protective member serves as a mediator that covers and protects the terminals from cutting dust and contamination. By positioning the protective member to cover the terminals during the cutting process, it creates a protective barrier that prevents harmful particles from contacting the terminals while allowing the front side to be held for secure processing
Solution Approach 2:
The protective member is attached to the workpiece before the cutting operation begins. This preliminary action ensures that the terminals are already protected before any cutting dust or contamination can occur, preventing terminal damage proactively rather than reacting to damage after it occurs

AI summary
A processing method for dividing a plate-shaped workpiece into a plurality of individual packages along a plurality of crossing division lines, in which the workpiece has terminals on the back side, includes the steps of attaching a protective member to the back side of the workpiece so as to cover the terminals to thereby unite the protective member with the workpiece, dividing the workpiece with the protective member along each division line to obtain the individual packages in a condition where the protective member is attached to each package, forming a conductive shield layer on the outer surface of each package, and peeling the protective member from each package.
