The need for this guideline arose from widespread lack of consistency in characterizing electrical parameters of electronic packages, which existed in the industry until the early 1990s. Then, the JEDEC Committee JC-15 provided the forum where various methods were discussed and commonality in approach emerged. The result is that today we have relatively consistent results in measuring and reporting electrical package parameters, as well as specialized tools (e.g., the IPA-510, the interconnect parameter analyzer) which were developed to support the methodology.
