Overview

The HAST Series is designed for situations where you simply cannot afford to wait weeks for reliability data. By subjecting products to a mix of high temperature, high humidity, and high pressure, this HAST chamber accelerates the aging process dramatically.

It condenses what would normally take weeks of standard Temperature Humidity Bias (THB) testing into just a few days, making it the most efficient way to validate the long-term durability of semiconductors, microelectronics, and solar panels.

Key Features

• The Power of Pressure: The core advantage of a highly accelerated stress test is the addition of pressure to the testing environment. This "unsaturation" mode forces moisture to penetrate materials much faster than atmospheric tests ever could. It is the most effective method for spotting potential failures—such as package cracks, corrosion, or electrical leakage—before your product hits the market.

• Built for Rigorous Standards: This equipment is engineered to help you meet the strictest global reliability guidelines. It ensures full compliance with critical industry standards like JEDEC JESD22-A118, IEC 60068-2-66, and MIL-STD 883, giving you confidence that your components are ready for aerospace, automotive, or military applications.

• Superior Construction: We built this chamber to last. The exterior is crafted from premium cold-rolled steel with a durable anti-static finish. Inside, the workspace is lined with SUS316 matte stainless steel, which offers excellent resistance to the harsh, high-pressure, and wet conditions generated during hast testing.

• Advanced Safety & Insulation: Handling high pressure and heat requires robust safety measures. The unit features high-grade ultra-fine glass wool insulation (A1 flame-retardant certified) to keep the heat contained and the outer casing cool. It also includes comprehensive safety alarms to monitor pressure and temperature levels constantly.

• Intuitive Control System: Despite its complex capabilities, operating the machine is straightforward. The 7-inch color touchscreen allows you to set precise temperature, humidity, and pressure profiles with ease. You can monitor the test progress in real-time without needing to navigate through confusing menus.
