I am designing a PCB consisting a microcontroller in which I have to ensure that I have removable crystal . I am looking for a female connector in which I can easily plug/unplug/swap the crystal (usually has two outputs). I am designing the system using Eagle, however, I've had no luck finding a suitable connector. I believe there are a lot of female connectors available but I do know that there are some specifically designed to hold crystal. Is there an Eagle library consisting these holders? Can someone point me to the right eagle library?
Some microcontroller evaluation boards employ machined pin sockets that take a HC-49U type crystal. These socket pins seem to be very similar to high-quality dual-inline-package (DIP) pins. These socket pins can be purchased individually.
BUT notice that the crystal has a metal case, and requires a non-conductive gasket between crystal bottom and socket, otherwise the crystal's metal case can short out to the socket. In the photo, the un-plugged crystal gasket is white. Crystal socket pins are gold-coloured. The other 8 MHz crystal is soldered into the board.
I have just used 2 pins from a machine socket strip like this. Didn't seem to be any worse than crystal plugged into a breadboard. The pins are sunk into the plastic housing enough to isolate the pins from the case.
