Quality Control: Sanwood Technology's HAST Test Chamber Solidifies the Reliability Foundation of AI Chips

With the rapid development of the artificial intelligence industry, AI chips have become the core of computing power. High-end computing chips equipped with HBM high-bandwidth memory and dedicated ASIC chips are widely used in key areas such as data centers, intelligent driving, and industrial automation. As a professional manufacturer of environmental reliability testing equipment, Sanwood Technology's HAST Acceelerated Aging Test Chamber strictly adheres to mainstream international standards such as JESD22-A110 and AEC-Q100-010, helping companies identify product weaknesses during the design phase and address potential problems at the source.

Challenge: Potential Reliability Issues in AI Chip Packaging

The complexity of AI chip packaging far exceeds that of traditional chips, and failure mechanisms mainly focus on the following aspects:

1. Moisture Infiltration and Electrochemistry Migration

The HBM multi-layer stacked structure, the large-size ASIC substrate, and the thousands of micro bumps and TSV structures are highly susceptible to moisture corrosion in non-hermetic packaging. After moisture infiltration, ion migration is induced under bias voltage, leading to increased leakage current, metallization layer corrosion, and even short-circuit failure.

2.Interface layering and Adhesion Failure

Due to differences in thermal expansion coefficients between the molding compound and the substrate/chip, interface layering is accelerated under temperature and humidity coupling stress. Layering extending to critical signal paths directly leads to electrical open circuits or decreased signal integrity.

3. Corrosion Sensitivity of High-Density Interconnects: As AI chips evolve towards 2.5D/3D packaging, the density of micro bumps and interconnect complexity increase significantly. Precision structures are more sensitive to moisture and contaminants, leading to an exponential increase in corrosion risk.

Solution

To address these risks, Sanwood Technology's HAST Acceelerated Aging Test Chamber efficiently accelerates the aging process by applying temperature, humidity, and bias stress, helping companies quickly identify weak points.

HAST Acceelerated Aging Test Chamber Core Parameters

Temperature Range: +105℃~+145℃

Humidity Range: 65%~100%RH

Pressure Control Range: 0.1209MPa~0.415MPa (Absolute Pressure)

Equipment Advantages

Sanwood Technology's HAST Acceelerated Aging Test Chamber possesses the following core advantages:

Rapid Assessment of Encapsulated Moisture Resistance: Quickly assesses the moisture penetration resistance of plastic-encapsulated chips and the corrosion resistance of the internal metallized structure.

Automotive-Grade Chip Certification: A mandatory test item in AEC-Q100 certification, used to replace time-consuming traditional high-temperature and high-humidity tests.

High-pressure steam greatly accelerates the rate at which moisture penetrates the encapsulation and the internal corrosion reaction, causing wire corrosion and encapsulation layering.
