In electronic circuit maintenance and upgrading, the system carries product quality. If you use 20 pin ic base then you can easily change this ic from the circuit board and replace it if necessary. Sometimes we designing a smart circuit using a microcontroller. In this case, we need to upgrade our project according to time. If you soldering a microcontroller with the PCB then its does not possible to upgrade. So IC Base is very much import for standard electronic circuit designing. IC Base 20 Pin
