Abstract
A manufacturing method of voltage control oscillator (VCO) has the following steps. Firstly, a baseboard having an opening is provided. Then, an adjustable electronic device is installed on the baseboard, and an adjustable area of the adjustable device faces the opening of the baseboard. Also, a set of elements including a cover is installed on the baseboard. Then, the adjustable area of the adjustable electronic device is adjusted through the opening of the baseboard. Finally, the baseboard, the adjustable electronic device, and the set of elements make up one adjusted voltage control oscillator. The adjusted voltage control oscillator is then installed on another circuit board, and the surface of the circuit board and the opening form a sheltering space for the adjustable area of the adjustable electronic device.
