In this concise KZitem video, I reveal what's inside some quartz crystal resonators - a quartz crystal resonator teardown. We look inside some old quartz crystals, some not so old ones and some new ones including a surface mount quartz crystal resonator.
From old to new, quartz crystal resonators come in all shapes and sizes. They're used in all manner of electronic circuits providing high quality resonators to give stable and accurate signals for use as clock oscillators in computer, processor and logic circuits. They're also widely used in RF designs as oscillator resonant elements and in filters.
As the circuit symbol implies, they contain a slice of quartz crystal which is held between two electrodes.
So to investigate more about them, I took an old 1940s crystal apart and as I hope you can make out there is the slice of quartz between two metal electrodes. You see a teardown.
There are many modern crystals as well. From the larger ones to very small surface mount ones.
I broke into one. The metal can is sealed and its filled with an inert gas such as nitrogen.
We even looked inside a specialised SMD quartz crystal with a ceramic base.
We'd like to thank our friends at IQD Frequency Products Ltd for their help in supply the modern crystals and for taking apart the SMD one. They were very helpful and knowledgeable. www.iqdfrequen...
