Packaging and assembly
Which set correctly describes the main roles of a semiconductor package?
- AProtecting the chip from the external environment, connecting it electrically to the printed circuit board and removing the heat it generates
- BDesigning the chip's circuits
- CAdding more transistors inside the chip
Show answer and explanation
Answer: A. Protecting the chip from the external environment, connecting it electrically to the printed circuit board and removing the heat it generates
The package protects the fragile chip from moisture, shock and contamination, converts the chip's tiny electrodes into terminals large enough to connect to the PCB wiring, and carries heat generated in the chip to the outside.
- A. Correct. Protection, electrical connection and heat removal are its main roles.
- B. Circuit design is done in the design stage.
- C. The number of transistors is set in chip fabrication.
