Auxiliary Insertion Members for IC Chip Testing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IC chip testing apparatuses often fail to ensure proper electrical connection of IC chips to probes, leading to incomplete testing, as the mounting quality is not verified until after all chips have been tested.
Innovation Solution
A chip testing system comprising a chip tray kit with auxiliary insertion members and a temperature-adjusting device, which ensures stable connection and testing of IC chips under predetermined conditions by using pressing assemblies to maintain chip alignment and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If IC chips are mounted onto the testing apparatus without preliminary checking, then the testing process can proceed quickly, but some chips may not be properly connected and cannot be correctly tested
Solution Approach 1:
The patent applies preliminary action by introducing an auxiliary insertion member that checks chip mounting quality before the actual testing process. The auxiliary insertion member includes checking pins that preliminarily verify whether chips are properly connected to the testing apparatus, preventing improperly mounted chips from entering the testing process and ensuring reliable connections before high-frequency testing begins
2Reliability
If auxiliary insertion members are added to check chip mounting, then mounting quality can be verified, but the device complexity increases
Solution Approach 1:
The patent merges the auxiliary insertion member with the existing chip tray kit structure. The auxiliary insertion member is detachably coupled to the chip tray kit and integrates checking pins, limiting structures, and positioning features that work together with the existing chip accommodating slots and tray structure, verifying mounting quality without requiring a completely separate verification system
Solution Approach 2:
The auxiliary insertion member serves multiple functions: it checks mounting quality through checking pins, limits chip movement through limiting structures, provides positioning through positioning structures, and can be detachably coupled for flexibility. This multi-functional design verifies mounting reliability without proportionally increasing device complexity
3Reliability
If pressing assemblies with temperature control are used to press chips, then connection stability improves, but energy consumption increases
Solution Approach 1:
The patent applies parameter changes by using pressing assemblies that can adjust pressing force and temperature parameters. The temperature adjusting device controls the temperature of pressing members to optimize the connection between chips and the testing apparatus, improving connection stability through controlled thermal parameters while managing energy consumption through precise temperature regulation

AI summary
A chip testing system including a tray kit, an insertion member mounting apparatus, a testing apparatus, an insertion member detaching apparatus, and a conveying apparatus are provided. The chip tray kit includes a tray, a plurality of chip fixing members, and a plurality of auxiliary insertion members. The chip fixing members are fixed to the tray and are configured to carry a plurality of chips. The insertion member mounting apparatus can fix the auxiliary insertion members to a side of the chip fixing members, and the auxiliary insertion members can limit a movement range of the chips in the chip fixing members. The insertion member detaching apparatus can detach the auxiliary insertion members. When the chips are tested, a pressing assembly connected to a temperature adjusting device and reaching a predetermined temperature correspondingly presses a surface of each of the chips.
