| Aspect | IC (Integrated Circuit) | PCB (Printed Circuit Board) |
| Purpose | Performs a specific function, such as processing or control. | Provides a platform to connect and arrange components. |
| Structure | A small silicon chip with micro-components embedded inside. | A flat board with conductive traces and mounted components. |
| Functionality | Acts as the "brain" of the circuit. | Acts as the "body" holding all components together. |
| Material | Made primarily of silicon and encapsulated in resin. | Made of fiberglass, copper, and insulating materials. |
| Complexity | Contains millions of micro-components in a tiny space. | Consists of layers of conductive and insulating materials. |
| Manufacturing | Requires advanced semiconductor fabrication techniques. | Manufactured through processes like etching, drilling, and soldering. |
| Applications | Found inside chips for computation, memory, or control tasks. | Found in almost every electronic device, connecting components. |
Reliability isn’t decided by the shell —
— POE PCB/PCBA Manufacturer (@poe_pcba) December 12, 2025
it’s the PCBA inside, built to stay stable under vibration, heat, and long operating hours.
That’s the part users never see,
but engineers and buyers know it’s where reliability is decided. #PCBA #HardwareDesign #Electronics #EMS pic.twitter.com/db7gyUhmUn
Since 1996, POE has become a globally renowned PCB company, providing small to medium volume PCB/ PCBA manufacturing services.
