The UNO R3 SMD band is based on Atmega328 SMD Package Microcontroller. It has 14 digital input/output pins (out of which 6 can be used as PWM output), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It is assembled with the CH340 USB to Serial converter chip. The UNO R3 SMD band consists of 2 rows of holes for the pins (Male and Female), so it can be connected with normal female jumper wires. It also has 3 additional rows of holes for wiring. The board has onboard LEDs to indicate power. Also, the IC Atmega328P is removable. This means that if the Atmega328P IC is not working then it can be replaced with another one.
