So this is an SMD IC chip made in the app 'Blender'. What is SMD? SMD means surface mount device where components are attached directly on the top side of a PCB. What is IC chip? IC chips are basically small electronic components which are basically circuits (IC = Integrated circuits) but in a really small scale. These ic chips have more than 10 billion transistors in them. Not only transistors but also other components such as resistors, diodes etc.
