Product Introduction
Product Specifications: Meets 35~55L standard capacity and other non-standard customized models
Product Introduction: Used to evaluate the operational reliability of non-hermetic packaged IC devices (solid-state devices) under high temperature and high humidity conditions, and to perform high-accelerated stress life aging tests on chips, semiconductors, and other components with temperature, humidity, and bias voltage.
Product Alias: BHAST, Bias High Accelerated Life Test Chamber, Temperature and Humidity Bias Life Aging Test Chamber, High Temperature and High Humidity Bias Humid Heat Aging Chamber
I. Test Standards Met:
AEC Q101 (Automotive Grade Chips)
JIS C0096-2
GB/T2423.40-1997 Environmental Test for Electrical and Electronic Products Part 2: Test Methods Cx: Constant Humid Heat of Unsaturated High-Pressure Steam
IEC60068-2-66-1994 Environmental Testing. Part 2-66: Test Methods. Test Cx: Steady-State Humid Heat
JESD22-A100 Cyclic Temperature and Humidity Offset Life
JESD22-A101 Steady-State Temperature, Humidity/Bias, Life Test (Temperature Humidity Bias Life)
JESD22-A102 High-Pressure Steam Test (Accelerated Moisture Resistance Penetration)
JESD22-A108 Temperature, Bias Voltage, and Operating Life
JESD22-A110 HAST High Accelerated Temperature and Humidity Stress Test
II. Application Fields: PCB, LCD Board, Battery, Capacitor, Resistor, IC Semiconductor, Connector, Circuit Board, Magnetic Material, Polymer Material, EVA, Photovoltaic Component, Automotive Grade Chip
1. The inner tank uses a double-layer arc design to prevent dew condensation during the test, thus avoiding the impact of direct hot steam on the product during the test and affecting the test results.
2. Uses a high-efficiency vacuum pump to achieve the optimal pure saturated steam state in the chamber.
3. Uses a 7-inch true color touch screen, with 250 groups and 12500 segments of programs, and has USB curve data download function and RS-485 communication interface.
4. Automotive-grade silicone overall sealing strip, good airtightness, durable.
5. Automatic water replenishment function, front-mounted water level confirmation.
6. Uses dry and wet bulb sensors for direct measurement (control modes include: dry and wet bulb, unsaturated, and wet saturation, 3 modes in total).
