Abstract:
A method for manufacturing an integrated RTC IC package, the method comprising the steps of:providing a printed circuit board (PCB);soldering at least one capacitor soldered on the PCB with soldering points;soldering a quartz oscillator soldered on the PCB with soldering points;examining the soldering points to identify defective soldering points;reworking the defective soldering points until the defective soldering points pass the examination;providing a real time clock integrated circuit (RTC IC), wherein a plurality of pins of the RTC IC are bent upward and the RTC IC pins are rectified;soldering the PCB on a surface of the RTC IC with soldering points;providing a battery soldered on the PCB with soldering points;examining the soldering points and measuring a battery voltage;re-soldering the soldering points if the soldering point fails to pass the examination;replacing the battery if the battery voltage is abnormal;charging the battery;measuring a signal frequency from the RTC IC and the battery voltage to identify abnormalities;fixing up the abnormalities until the signal frequency from the RTC IC and the battery voltage are both correct;providing a packaging cover and a gluing material;filling the gluing material into the packaging cover;assembling the packaging cover filled with the gluing material and the RTC IC soldered with related components to produce the integrated RTC IC package; anddrying out the integrated RTC IC package naturally.
