<\/a><\/p>\nTechnical Core: Precise Temperature Cycling and Thermal Flow Visualization<\/p>\n
The core value of a thermal stream system<\/a> lies in its ability to construct a three-dimensional testing scenario involving temperature, time, and stress. It operates by utilizing a high-precision PID algorithm to control hot and cold airflow, enabling rapid temperature transitions between 80°C and 225°C at rates of up to 50°C\/min. Taking automotive-grade chip testing as an example, the equipment employs independent dual-channel temperature control technology; when simulating TC3 conditions (-40°C to +125°C), it dynamically adjusts compressor power and airflow velocity to precisely maintain the temperature change rate within a range of 15°C\/min ± 2°C.<\/p>\n This parameter configuration directly impacts the accuracy of solder joint fatigue life verification. For instance, during testing of a specific AI chip, the system detected a 35% degradation in solder joint shear force after 1,000 cycles, thereby providing a six-month early warning regarding the risk of CTE (Coefficient of Thermal Expansion) mismatch.<\/p>\n Regarding data acquisition, modern thermal stream systems have transcended the limitations of traditional Thermal Chamber<\/a>s. One specific model, for example, features a nanoscale thermopile sensor array capable of detecting minute temperature variations as small as 0.01°C; when combined with infrared thermal imaging technology, it can generate detailed thermal hotspot maps of the chip’s surface.<\/p>\n Four Key Test Scenarios: Decoding Chip Thermal Failure<\/p>\n 1. Temperature Cycling Test<\/a> (TCT)<\/p>\n For automotive electronic chips, the thermal stream system simulates extreme temperature fluctuation environments ranging from -55°C to +175°C. The equipment employs a stepped temperature control strategy: a ramp rate of 20°C\/min is used for stress screening during the first 500 cycles, while the rate is reduced to 5°C\/min for reliability verification during the subsequent 500 cycles.<\/p>\n In a test involving power devices, the equipment dynamically adjusted voltage and junction temperatures to boost early-failure chip screening efficiency by 40%, strictly adhering to AEC-Q100 Grade 3 standards.<\/p>\n 2. High-Temperature Burn-in Test<\/p>\n Under sustained stress at 125°C, the thermal stream system tracks electromigration failures in real-time using four-wire resistance monitoring. Its built-in current source module provides a wide excitation range (0.1 µA to 10 A); combined with nanovolt-level voltage acquisition precision, it successfully detected on-resistance drift in a MOSFET during a 72-hour burn-in test—identifying potential failure 120 hours earlier than traditional methods.<\/p>\n 3. Thermal Resistance Test (Rth)<\/p>\n Combining heat flux density measurement with thermocouple monitoring, the equipment utilizes the JESD51-14 standard test method. During a wafer-level package test, a combination of SEM and infrared technologies revealed that when heat flux density exceeded 0.8 W\/mm², the thermal resistance of a 5-layer stacked package rose exponentially—a phenomenon directly linked to process deviations in TSV (Through-Silicon Via) interconnect apertures.<\/p>\n Test data indicates that packaging structures utilizing silicon carbide (SiC) substrates can reduce thermal resistance to 0.7°C\/W.<\/p>\n 4. Thermal Shock Test<\/p>\n During the testing of an aerospace-grade chip, the thermal stream system achieved instantaneous temperature switching between -196°C and +300°C. Utilizing a hybrid system of liquid nitrogen injection and infrared heating, the equipment completed temperature transitions within 10 seconds while keeping temperature overshoot within ±3°C. Test results indicate that the ceramic package exhibits a thermal stress coefficient of 2.3 × 10\u207b\u2076\/°C under extreme temperature differentials, successfully passing JAXA’s satellite component certification.<\/p>\n Breakthroughs in Industry Applications<\/p>\n New Energy Vehicles: Utilized a dual-loop feedback system (integrating heat flow and electric current) to reduce BMS stability verification time by 40% and precisely pinpoint current density anomalies at the 0.5 mm² scale.<\/p>\n 5G Communication Base Stations: Employed multi-physics coupling simulation technology to optimize chip power consumption by 15% and established a failure threshold model for thermal runaway with a false alarm rate as low as 0.05‰.<\/p>\n Aerospace: Conducted full-temperature-range testing on materials for Long March rocket fuel tanks, identifying the formation of micro-cracks at the 0.02 mm scale when heat flux density exceeded 1.2 W\/cm².<\/p>\n As a specialist in high- and low-temperature control, Huanyi Instruments is setting performance standards for thermal stream systems—featuring an ultra-wide temperature range of -120°C to +300°C and the capability to transition from +150°C to -55°C in under 10 seconds—thereby delivering more accurate and effective solutions for semiconductor testing.<\/p>\n About us<\/p>\n Dongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007, covering an area of 6,022 square meters.
