Keysight Technologies, Inc. introduces the Electrical Structural Tester (EST), a wire bond inspection solution for semiconductor manufacturing that ensures the integrity and reliability of electronic components.
The semiconductor industry is faced with testing challenges due to the increasing density of chips in mission-critical applications such as medical devices and automotive systems. Current testing methodologies often fall short in detecting wire bond structural defects, which lead to costly latent failures. In addition, traditional testing approaches frequently rely on sampling techniques that do not adequately identify wire bond structural defects.
The EST addresses these testing challenges by using cutting-edge nano Vectorless Test Enhanced Performance (nVTEP) technology to create a capacitive structure between the wire bond and a sensor plate. Using this method the EST can identify subtle defects such as wire sag, near shorts, and stray wires to enable a comprehensive assessment of wire bond integrity.
Key benefits of the EST include:
- Advanced defect detection – Identifies a wide range of wire bond defects, both electrical and non-electrical, by analyzing changes in capacitive coupling patterns to ensure the functionality and reliability of electronic components.
- High-volume manufacturing ready – Enables throughput of up to 72,000 units per hour through the ability to test up to 20 integrated circuits simultaneously, which boosts productivity and efficiency in high-volume production environments.
- Big data analytics integration: Captures defects and enhances yield through advanced methods like marginal retry test (MaRT), dynamic part averaging test (DPAT), and real-time part averaging test (RPAT).
Carol Leh, Vice President, Electronic Industrial Solutions Group Center of Excellence, Keysight, said: “Keysight is dedicated to pioneering innovative solutions that address the most pressing challenges in the wire bonding process. The Electrical Structural Tester empowers chip manufacturers to enhance production efficiency by rapidly identifying wire bond defects, ensuring superior quality and reliability in high-volume manufacturing.”
The Electrical Structural Tester will be showcased at the Keysight booth (K3283) at SEMICON Taiwan 2024, Taipei Nangang Exhibition Center Hall 1, September 4-6, 2024.

Toshiba Electronics Europe GmbH has launched a small new intelligent power device (IPD) for space-constrained brushless DC (BLDC) motor drive applications such as air conditioners, air purifiers, and pumps.
The new IPD (TPD4165K) has an increased maximum output current of 3A, compared to the 2A rating of Toshiba’s existing products like TPD4163K, or TPD4164K. This extends the range of supported equipment and allows use in higher power applications. The device is suitable for sine-wave drive.
As power supply voltage may fluctuate significantly in some regions where the IP could be used, the absolute maximum voltage rating (VBB) has been increased to 600V to enhance long-term reliability. This represents a 20% increase over Toshiba’s previous products (TPD4123K, TPD4123AK, TPD4144K, TPD4144AK, TPD4135K, TPD4135AK).
The new TPD4165K is housed in a through-hole HDIP30 package. This has a 21% smaller footprint than the DIP26 package used for many of Toshiba’s previous products, simplifying the design process for challenging space-constrained applications. The new device measures just 32.8mm x 13.5mm x 3.525mm. It supports either three-shunt or single-shunt resistor circuit for current sensing.
Built into the new IPD is a range of safety features including over-current, under-voltage and thermal shutdown. Additionally, an external signal can be applied to the SD pin to control the behaviour of the output stage. The DIAG output pin provides the status of the safety conditions.
Designers can freely access a reference design for a sensorless BLDC motor drive circuit based upon the new TPD4165K and Toshiba’s TMPM374FWUG microcontroller with vector control engine capability. The reference design data can be downloaded from Toshiba’s website.
Toshiba will continue to expand its product range by adding devices with improved characteristics. This will assist designers by improving design flexibility as well as contributing to carbon neutrality through energy-saving motor control.
