What is Wafer Level Chip Scale Package (WLCSP)?

WLCSP is a semiconductor packaging technology in which integrated circuits (ICs) are packaged directly at the wafer level rather than after the wafer is diced into individual chips. This process allows manufacturers to produce extremely compact and high-density packages.

Key advantages include:

• Ultra-compact size and reduced footprint
• Enhanced electrical performance with shorter interconnects
• Cost-effectiveness through wafer-level batch processing
• Improved thermal performance and reliability

WLCSP is widely adopted in mobile, wearable, and high-speed computing devices due to its miniaturization benefits.
