In the fast-paced semiconductor industry, precision, reliability, and speed are paramount. As chips become increasingly complex and miniaturized, testing them during production is more critical than ever. This is where probe cards come into play—acting as the crucial interface between semiconductor wafers and automated test equipment (ATE).

The Probe Card Market is witnessing robust growth, fueled by the demand for high-performance chips in 5G, AI, automotive, and consumer electronics. With increasing wafer sizes, advanced packaging, and multi-die integration, probe card technology is evolving rapidly to meet next-generation semiconductor testing needs.

What is a Probe Card?

A probe card is a testing interface used in semiconductor wafer testing to make temporary electrical contact between the test system and the chip's bonding pads. It is placed between the wafer prober and the automated test equipment (ATE).

Key functions of probe cards:

• Transmit electrical signals for functionality testing

• Ensure contact precision with small, densely packed IC pads

• Enable parametric and functional testing before chips are diced and packaged

Probe cards are designed based on wafer layout and testing requirements and can contain thousands of microscopic probes for high-density testing.

Types of Probe Cards

1. Cantilever Probe Cards

   • Feature needle-like probes

   • Widely used for low pin count applications and legacy ICs

2. Vertical Probe Cards

   • Probes are mounted vertically, allowing shorter signal paths

   • Suitable for high pin count and advanced nodes

3. MEMS Probe Cards

   • Use microelectromechanical systems for precision and scalability

   • Support fine-pitch, high-frequency, and multi-die testing

4. Advanced Probe Cards (e.g., Probe-on-Substrate)

   • Incorporate complex circuitry and signal processing

   • Used in high-speed digital and RF applications
