Problems solved by technology

Existing chips are generally installed on a circuit board, and the clock frequency is provided by an external crystal oscillator, but such a chip provided by an external crystal oscillator will occupy a certain amount of space, and the area occupied by the entire circuit is relatively large. , the integration level is not high, and secondly, because the crystal and the chip are separated, the working environment will always be different, so that there will be errors in the cooperation between the crystal and the chip, which will affect the stability of the chip
Moreover, the crystal oscillators used in existing chips are usually SMD crystal oscillators, but due to the high cost of SMD crystal oscillators, it is not conducive to reducing the cost of the entire chip.

Description

technical field [0001] The invention relates to a semiconductor chip welding package, in particular to a crystal oscillator welding method. Background technique [0002] A semiconductor chip is usually an integrated circuit composed of many transistors that can perform certain functions. Usually, a chip needs an external clock to provide an accurate clock frequency. In order to ensure the reliable function of the integrated circuit, the clock frequency provided to the circuit must be stable and reliable. Existing chips are generally installed on a circuit board, and the clock frequency is provided by an external crystal oscillator, but such a chip provided by an external crystal oscillator will occupy a certain amount of space, and the area occupied by the entire circuit is relatively large. , the integration level is not high, and secondly, because the crystal and the chip are separated, the working environment will always be different, so that there will be errors in the c...
