Abstract
An automated system capable of measuring temperature dependent mechanical properties based on extensional strain has been developed. The system uses either the electrical resistance strain gage technique or a laser extensometer device in conjunction with user programmable thermal cycling, load cycling and data acquisition. An IBM-compatible 486 computer with commercially available software is used to regulate the test cycling and data acquisition. This system is being used to characterize the mechanical properties of printed wiring board (PWB) core materials over manufacturing temperature ranges. This paper will discuss the integration of system components and the system capabilities. Experimental results for 1080 FR-4 Prepreg and copper-foil clad laminate will be presented as well as a comparison of the contact and non-contact methods used for strain measurement.
