The crystal vibration オン PCB does not vibrate

In a line, crystal vibration does not vibrate, how to solve this problem? According to our electronic engineers and customer contact, summed up the circuit board crystal vibration can not vibration five solutions, I hope to help you.

Crystal oscillator schematic diagram

First, to eliminate the possibility of line error, it is suggested to try to compare with the recommended circuit of the corresponding type of line.
Two, exclude the external components of the bad situation, because the external parts are nothing more than resistance, capacitance, you can easily identify whether it is defective.
Three, eliminate the possibility that crystal vibration is not vibration products, it is recommended to try a few crystal vibration, not to try one or two.
Four, you can change the capacitance at both ends of the crystal, maybe the crystal oscillator can work normally, the size of the capacitor please refer to the crystal oscillator instructions.
Five, in the 回路基板 wiring crystal circuit wiring should be as short as possible and as close to IC, put an end to the crystal foot wiring.
I believe that the use of these five methods, generally speaking, can solve the crystal vibration on the circuit board can not vibration, if you still have questions, you can directly consult contact.
