Lab Companion is deeply engaged in the semiconductor testing field. To address the core needs of precision testing in the industry, we have launched a semiconductor chip-specific high and low temperature humidity test chamber. With a high-cleanliness chamber structure and precise temperature and humidity control as its core highlights, the equipment is specially designed to provide full-scenario high-low temperature and humidity alternating environment testing for products such as chip wafers, bare chips, packaged devices, and semiconductor modules. It can fully meet the core needs of chip packaging reliability verification, aging testing, and environmental adaptability evaluation, providing stable, accurate, and clean test environment support for semiconductor product R&D, process optimization, and quality control.

I. Product Positioning: Specialized for Semiconductor Chips, Different from General-Purpose Test Equipment

This series of test chambers abandons the homogeneous design of general-purpose equipment and is fully optimized and upgraded around the precision characteristics of semiconductor chips. In terms of environmental cleanliness, temperature and humidity control accuracy, cabinet material selection, and anti-pollution structural design, it meets the strict requirements of chip testing. It can effectively avoid damage to precision chips caused by pollutants such as dust, impurities, and condensed water, and is widely applicable to core scenarios such as reliability assessment, failure analysis, and process verification before and after chip packaging. It is an exclusive and suitable equipment for semiconductor enterprises, packaging and testing factories, and research institutions to carry out chip environmental reliability testing.

II. High-Cleanliness Chamber Design: Building a Solid Line of Defense for Precision Chip Testing

The equipment adopts a high-cleanliness chamber structure, and the inner tank is made of high-quality mirror-finish 304/316 stainless steel. Its surface is smooth and dense, not easy to adhere to dust and impurities, and easy and efficient to clean and maintain. It reduces pollution to the chip surface, pins, and packaging structure from micro-particle dust at the source, ensuring that test samples are free from secondary damage.

The internal corners of the chamber adopt a full arc transition design, completely eliminating dead corners and greatly reducing the risk of dust accumulation. The air duct system has undergone professional dust-proof optimization, combined with a low-dust emission air supply mode, to continuously maintain a high-cleanliness state in the test space, perfectly matching the cleanliness requirements of chips, wafers, and packaged devices for the test environment. At the same time, the chamber adopts a tight sealing structure, which effectively blocks the entry of external air impurities and creates a stable, clean, and interference-free internal environment for chip testing.

III. Core Temperature and Humidity Parameters: Precisely Matching the Needs of Chip Packaging Reliability Testing

The temperature range of the equipment fully covers typical test scenarios such as chip low-temperature storage, high-temperature aging, and temperature-humidity cycling. It can be continuously adjusted over a wide range, with precise and stable control of temperature fluctuation and uniformity. It can provide uniform environmental stress for core components such as chip packaging layers, bonding wires, and substrate materials, ensuring that test results are consistent with actual application scenarios.

The humidity range can flexibly cover from low-humidity dry environment to high-temperature and high-humidity environment, accurately adapting to core chip packaging reliability projects such as accelerated humidity aging and Moisture Sensitivity Level (MSL) testing. The humidity control response is stable, effectively avoiding problems such as chip surface condensation, packaging colloid cracking, and pin oxidation caused by sudden humidity changes. It strictly complies with relevant semiconductor industry test standards, ensuring the standardization and reliability of the test process.

IV. Precise Temperature and Humidity Control: Ensuring Stable and Reliable Test Data

The control system is equipped with high-precision temperature and humidity sensors, combined with an intelligent PID adjustment algorithm, which can realize precise control and continuous stable maintenance of temperature and humidity. With small temperature and humidity fluctuations and excellent uniformity, it ensures that the same batch of chip samples is subjected to uniform stress during the test, and the test data has good repeatability and comparability, providing accurate data support for chip quality evaluation.

The equipment supports multi-segment program editing function. According to chip testing needs, it can customize the temperature and humidity rise and fall rate, holding time, and cycle times, perfectly adapting to the complex temperature and humidity alternating processes in chip packaging reliability testing. The program runs stably without parameter drift, which can meet the needs of long-term continuous aging testing and greatly improve test efficiency and accuracy.

V. Structure and Function Adaptation: Meeting Full-Scenario Chip Packaging Testing

The internal space of the chamber is compact and reasonably laid out, which can flexibly place test accessories such as chip trays, carriers, and packaging fixtures. It supports batch placement and testing of small-size chip samples, effectively improving test efficiency and adapting to the large-scale testing needs of enterprises.

The chamber is reserved with small lead holes and high-definition observation windows, which facilitate real-time monitoring of chip electrical parameters during the test, and can directly observe changes in chip appearance and status to detect test abnormalities in a timely manner. The internal air duct adopts a gentle air supply design, avoiding direct scouring of the chip surface by strong air flow, preventing chip displacement and damage, and is especially suitable for testing precision samples such as wafers and thin packaged chips.

VI. Multiple Safety Protections: Safeguarding the Operation of Chips and Equipment

In response to the precision and safety needs of chip testing, the equipment is equipped with a comprehensive safety protection mechanism, including over-temperature protection, humidity over-limit alarm, compressor overload protection, water shortage protection, leakage protection and other multiple functions. During long-term reliability tests, it can automatically monitor the equipment operation status in real time. Once an abnormality occurs, it will immediately shut down and alarm, effectively avoiding the impact of equipment failure on chip samples and ensuring the safety and continuity of the test process.

The refrigeration system adopts a low-vibration design, which greatly reduces vibration during equipment operation, avoids additional mechanical stress interference caused by vibration to chip bonding structures and micro-packaging components, further improves the stability of the test process, and protects the integrity of the chip structure.

VII. Typical Applications: Covering Full-Process Reliability Verification of Chip Packaging

The equipment can fully cover the full-process reliability testing of chip packaging. Before packaging, it can perform high-low temperature and humidity environment testing on wafers and substrate materials to verify the stability of materials under different environmental conditions and provide a basis for packaging process optimization. After packaging, through tests such as high-temperature and high-humidity aging, temperature cycling, and humidity storage, it can accurately evaluate the bonding reliability of packaging colloid, pads, and lead frames, and quickly identify potential failure problems such as delamination, cracking, and leakage.

At the same time, the equipment can be widely used in scenarios such as chip Moisture Sensitivity Level (MSL) verification, automotive chip environmental adaptability testing, consumer electronics chip reliability sampling inspection, and industrial chip weather resistance testing. It provides accurate and reliable data support for chip design optimization, packaging process improvement, and factory quality screening, helping enterprises improve product competitiveness.
