Pinboard Repair Jig for Inverted Pin Cleaning and Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accumulation of foreign substances on the pins of a pinboard during repeated contact with test pads of electronic devices leads to contact defects, deteriorating the inspection reliability of electronic devices.
Innovation Solution
A pinboard repair jig is designed with a support, top plate, linear motion guide, and location pins to facilitate easy inspection and repair of the pinboard, allowing it to be mounted in an inverted position for efficient cleaning and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pinboard is used repeatedly for inspecting electronic devices, then the inspection function is maintained, but foreign substances accumulate on the pins causing contact defects and deteriorating inspection reliability
Solution Approach 1:
The pinboard is designed to be easily detachable and repositionable, allowing maintenance personnel to perform preliminary cleaning actions before foreign substances cause contact defects. The linear motion guide enables the pinboard to be moved to a horizontal position for preventive maintenance, eliminating foreign substances before they accumulate to problematic levels.
Solution Approach 2:
The pinboard is designed to be mounted in an inverted position on the repair jig, with pins facing upward in a horizontal orientation. This inversion allows gravity to assist in draining liquids away from the pins and enables easy access for cleaning foreign substances from the pin surfaces using tools like air blowers or cleaning brushes.
2Ease of repair
If the pinboard requires repair due to foreign substance accumulation, then contact defects are addressed, but repair time and costs increase due to disassembly requirements
Solution Approach 1:
The pinboard is designed as a separate, detachable component that can be independently removed from the inspection system and mounted on the repair jig. This segmentation allows the pinboard to be repaired without disassembling other system components, reducing repair time and complexity.
Solution Approach 2:
A repair jig serves as an intermediary device that facilitates pinboard maintenance. The jig provides a stable mounting platform with linear motion guidance, allowing the pinboard to be positioned optimally for cleaning and inspection without requiring disassembly of the main inspection system.
3Ease of operation
If the pinboard is mounted in a conventional position, then structural stability is maintained, but effective cleaning and inspection of pins become difficult
Solution Approach 1:
The pinboard mounting system incorporates a linear motion guide that allows the pinboard to be dynamically repositioned between different orientations. The pinboard can be moved along the linear guide to achieve optimal positions for both stable mounting during operation and accessible positioning for cleaning and maintenance.
Solution Approach 2:
The conventional fixed mechanical mounting is replaced with a linear motion guide system that provides both stability during inspection operations and ease of repositioning for maintenance. The guide system allows smooth, controlled movement of the pinboard without requiring complex disassembly mechanisms.
