In our last blog post, we discussed the topic of date codes on quartz crystals. We looked at how irresponsible QA procedures by some manufacturers, distributors and customers can create significant environmental waste and added costs by rejecting components that are over two years old – a misguided requirement that certain companies have sought to implement. Quartz crystals, which today are almost always housed in hermetically sealed packages, do age a little. Their series-resonance frequency may change by a few parts per million over a period of years and this will be due, principally, to minute increases in the crystal’s mass, due to deposition of impurities inside its packaging that adhere to the crystal’s surface. The better the quality control during manufacturing, the lower the level of impurities and the less the change in frequency. Such changes are also affected by… Read Full Blog Post
