Packaging, Test & Assembly Process Overview

The Packaging, Test, and Assembly process is a crucial stage in semiconductor manufacturing, ensuring that chips are durable, reliable, and ready for integration into devices like smartphones, IoT systems, and industrial equipment.
These steps transform delicate wafers into robust and functional electronic components that meet the demands of modern technology.

 

Packaging

 

Packaging provides physical protection for semiconductor devices, shields them from environmental hazards, and manages heat dissipation during operation.
It also enables electrical connections between the chip and external systems, making it an essential process for device functionality.

Key packaging techniques include:

• Wire Bonding: Using thin wires to connect chip pads to external pins.
• Flip-Chip Bonding: Directly connecting solder bumps on the chip to the substrate for higher performance and compact design.
• System-in-Package (SiP): Combining multiple components, such as processors and sensors, into a single, compact package for multi-functional applications.

 

 

 

Assembly

 

Assembly involves integrating components into a complete, functional package, ready for deployment in electronic systems.
Each step in the assembly process requires precision to ensure reliability and performance.

Core assembly steps include:

• Die Attach: Bonding the semiconductor die to its substrate or base with accuracy.
• Encapsulation: Applying protective materials to shield the die and connections from mechanical and environmental damage.
• Marking and Singulation: Engraving identification marks on the package and separating individual units for final use.

 

 

 

 

Testing

 

Testing is the final step that validates the functionality and reliability of semiconductor devices before they are shipped to customers.
This step ensures compliance with stringent quality standards and optimizes performance.

The testing process is divided into:

• Wafer Testing: Screening wafers before they are diced into individual dies, helping to detect early defects.
• Final Testing: Conducting rigorous electrical, thermal, and mechanical tests after packaging to ensure the device operates as intended under real-world conditions.
