TIM Tester Precision Test Disks:
Sacrificial Copper Disks for Testing Adhesive Materials
When testing adhesive materials, sacrificial disks are often used to avoid adhesive damage to the test surfaces of the TIM Testers. For this application, the adhesive material is sandwiched and cured between two highly conductive metal disks that can be discarded after the test. These precision disks are carefully machined for flatness and thickness-uniformity to provide an ideal test vehicle for adhesive materials. Disks are also commonly used when the grease or adhesive layer is to be heat-aged and then retested.
The disks are nominally .12" (3.0) mm thick, sufficient to reduce the chance of warping or curvature during routine handling. The disk diameter is 1.3" (33 mm) to exactly match the ideal sample diameter for the TIM Testers.
'Standard' Precision Copper Disk
When using precision test disks, the adhesive must be installed in a uniform thickness "sandwich" for optimum test accuracy. This can be a difficult task. To improve the overall ease of assembling uniform thickness "sandwiches" disks are available with thickness adjustment screws as well as a center alignment tension screw to ensure sample integrity. These adjustable precision disks are particularly helpful for tests that involve sample-sandwich preparation, testing, aging, and retesting, The 3 thickness adjusting set screws provide the precise adjustments that maintain the desired thickness of the material under test while the alignment maintains light tension to hold the assembled sandwich together.
'Thickness Controlled' Precision Copper Disk
Application notes are available for detailed specifications on the preparation of samples.
