Semiconductor test has evolved to a level of safety, responsibility and reliability. The IC quality is absolutely important for self-driving cars because it concerns personal safety. When the car is driving in different environments, the temperature can change from high heat to freezing as well as high winds and rain all make the IC chip’s reliability a necessity. Moreover, for new applications, such as in VCSEL 3D image sensing, it has to be sure that it is no harm to people. All of these new applications provide a challenge to chip manufacturers and test equipment manufacturers for their ability to keep the car safe for drivers.

This means that semiconductor test equipment manufacturers need to work with customers earlier in the design process. Chroma ATE has been a Turnkey Solution provider with core technology in measurement since 2011, and is the only manufacturer equipped with testing and automation capability. Chroma’s products are mainly used in communication (FPD, color and video, optical components, power electronics, passive components, electrical safety, thermoelectric temperature control and automatic optics), semiconductor/IC, and clean technology (EV, green battery, LED lighting and solar energy) industries to effectively improve the quality of customer products and production efficiency in helping customers enhance their competitiveness.

Chroma has many product lines to fulfill the needs of semiconductor testing by supplying various kinds of equipment from R&D to mass production such as large ATE test systems, sorting machines and compact PXI test platforms, all of them have complete corresponding products to give customers the most appropriate selection. The complete semiconductor solution of Chroma covers different wafer test applications including consumer chips (microprocessors, audio chips, computers/mobile peripherals, etc.), power chips (linear regulators, DC converters, AC converters, LED drivers, etc.), radio frequency chips (wireless network, blue, blue, etc.), power chips (such as microprocessors, audio chips, computers / mobile peripherals, etc.), RF chips (wireless network, Bluetooth, mobile communication, etc.), and chips for specific testing areas (image sensors, radio frequency identification, etc.)

New IoT applications Initiate comprehensive semiconductor testing needs

Internet of Things (IoT) digitizes the real world by narrowing the scattered information and consolidating the digital information of things. It has a broad market and application prospects that is structured in three layers; sensing, network and application. Ranging from logistics and transportation, health care, smart environment (home, office and factory) along with personal and social areas, almost anything can be closely related to IoT. The IoT chip has been widely used in network and various types of sensors. For different applications in a test environment, the way to ensure that each IC’s function, performance and quality meet the standard is specifically important. Chroma’s Semiconductor BU general manager, George Chang, indicated that to cope with diversified applications, semiconductor wafer testing must incorporate a variety of test items including temperature, radio frequency (RF), precision and speed, to meet all types of IoT applications and customer needs.

Chroma provides complete semiconductor test solutions including SoC / VLSI/ Analog test solutions, IC test handlers, PXI IC test platforms and equipment corresponding to various types of IoT applications in testing embedded processor, MCU, RF MUC, Light Sensor, Magnetic Sensor, G-Sensor/Gyro, CMOS Image Sensor, Finger Print Sensor, Laser Diode, PMIC), and diversified wireless network implementation.

The widespread use of IoT creates a huge demand for micro control units and sensors, which lead to fierce competition in cost and production. As electronic products are always aiming for high cost-performance ratio with better functionality, Chroma is capable of providing competitive test instruments that are flexible to integrate with other equipment and automated systems to meet the demands for increased testing requirements and cost savings.

AI, smart driving, system level and burn-in test ensure final quality of IC

In light of the evolution of semiconductor process and packaging technology, the capabilities of ICs used in consumer electronics, automobiles, internet of things and artificial intelligence are getting more powerful with increased packaging density. Herbert Tsai, the ISS BU deputy general manager of Chroma ATE Inc. pointed out that for the complex packaging products such as SoC/SIP/3D ICs, besides inspecting the power and signal through traditional automated test equipment (mixed single ATE), the System Level Test (SLT) and Burn-in (BI) inspection process are also applied to do a comprehensive testing on IC to ensure its final quality.

As the IoV (internet of vehicle) and smart driving are growing trends, many car manufacturers have implemented ESC (electronic stability control) systems to receive and send signals through the sensor, camera, lidar and RF equipped on the car. When the system has collected the information from each component, it will quickly analyze and evaluate the vehicle status, and give commands to correct the steering wheel, slow down, brake or alarm. This means the system must have powerful semiconductor components to support the overall operation. These automotive systems have to remain in normal operation even under extreme conditions as they are related to driving safety. For varied driving environments, the demand for tri-temperature system level testing (Tri temperature SLT) on car chips is rapidly emerging. The product quality of car chips can be assured after rigorous and long-hour high/low temperature testing.

In recent years, the development of AI chips has been the frontline of first-tier manufacturers. The development of artificial intelligence at this stage is based on parallel computing technology and the depth of deep learning. Through the robust capabilities of self-learning and computing inside the chip, the equipment or systems are able to react properly in time. However, these types of high level chips (GPU/FPGA) are very expensive with strict quality demands, and passing through long hours of SLT/Burn-in test is the way to guarantee that every chip can operate normally under high temperature and high voltage environments.

Chroma has been dedicated to FT / SLT Handler technology research and development for a long time. In addition to the desktop equipment for the design house, Chroma also provides multi-functional and efficient test equipment for designers to use. Moreover, Chroma has introduced multi-probe tri-temperature test equipment to satisfy customer’s demand for mass production. The test technologies proprietary to Chroma can also be customized to meet customer needs providing the best test solutions.

In response to these policies, the international automakers have set up strategies to deal with these changes; for example, Volvo announced in July that all its car models launched after 2019 would be electric or hybrids.

HAITEC has been actively involved in the development of electric vehicles in recent years. Through the collaboration of industry, academia, and government, an ecosystem team encompassing motor, controller, battery, on-board charger and other key components manufacturers was formed to successfully create a Taiwan developed a smart electric vehicle. I-Shih also pointed out that the city S3 EV+ was developed suitable for Taiwan terrain and traffic condition as a smart energy passenger car with a speed dial b-Paddle. It is equipped with regenerative braking function to save energy when driving on the road, with power consumption of only 130Wh per kilometer. It can also be used as a mobile energy storage system (ESS) to integrate with micro-grid for household emergency use.

In electric vehicle powertrain system, Chroma is dedicated to developing motor control unit (power inverter). We aggressively cooperate with HAITEC to develop the controller exclusive to S3 EV + with power up to 150kW, efficiency up to 97%, and power density up to 15kW per liter. For the most important indicators of a vehicle – reliability and safety, Chroma’s motor control unit has passed the automotive level verification tests to be in compliance with international level quality.

At last, I-Shih expressed the appreciations to the consortium members, including Industrial Technology Research Institute, Automotive Research and Testing Center, National Taiwan University, Taiwan University of Science and Technology, and Taipei University of Science and Technology for their great efforts in completing the electrification of powertrain that was successfully been integrated in Taiwan’s first self-developed S3 EV+ smart electric vehicle, and making the automobile industry moving towards a whole new milestone.

Fast Transients, Low Noise in Chroma’s New Benchtop DC Power Supplies

Chroma’s newly launched 62000L Series programmable DC power supplies provide low ripple, low noise linear performance and a fast transient response in a lightweight, compact, and cost effective package.

As Chroma’s next generation of power supplies, the 62000L Series delivers pure and stable DC power as well as built-in features designed to meet the stringent requirements of next generation power electronics including automotive power electronics MCU/ECU, communication electronic parts, and semiconductor IC drivers.

Comparison of traditional models

Auto-ranging allows for freely adjusting the voltage and current. This feature eliminates the need to manually select the optimum range allowing all of the power to be available across all of the voltage and current settings.

Fast transient response makes the output voltage that changed due to load characteristics return to a stable supply of power in microsecond response speed. Take the 62010L-36-7 model for example, when the output current changes from half load to full load at the speed of 1A/μs, the voltage change of the actual output can return to 15mV within 30μs.

Low noise input power with pure quality protects the precision load or UUT from the interference of heavy noise. For example, the 62010L-36-7 output voltage noise is lower than 2mVp-p (20~20MHz) under the maximum rated current and maximum output power.

The auto sequencing programming function built into the 62000L Series allows the user to define and edit the output waveforms with 8 steps per cycle.

Conventional linear power supplies are cumbersome due to the frequency design and require more space for ventilation. Chroma simplified the design of the hardware architecture resulting in a better handling compact, lightweight design which is safer to stack.

The brand new 62000L Series programmable DC power supplies features an affordable price, high quality output specifications, practical functions, and standard USB and GPIB communication interfaces making this an excellent choice for testing small power and precision products.
