Specialty Environmental Test Chambers

Product Details:

HAST (Highly Accelerated Stress Test) chambers reduce the time it takes to complete humidity testing for semiconductors. By elevating temperatures above 100°C and increasing the pressure, simulation of normal humidity tests can be made while maintaining the same failure mechanisms. Tests can be completed in days, not weeks. 

Our HAST systems have a modern design that's easier to use: 

• Automatic humidity filling
• Automatic door lock 
• A more square workspace, allowing more product to be loaded 
• Convenient, hermetic power-pin system for bias testing
• We now offer a hermetic port connection to allow special signal lines like coax or fiberoptics to be run into the chamber. 
• You can use hermetic port plugs like those from Buffalo Conax with this port system.

Environmental stress screening (ESS) is also known as Burn-in, AST (Accelerated Stress Testing), HALT (Highly Accelerated Stress Test), or HASS (Highly Accelerated Stress Screening). Whatever the name, the idea is the same: create a test program that allows you to eliminate the infant mortality of your product. ESS5/11 SERIES The ESS5/11 Series provides the unique capability of stress screening products in a small, lab-type chamber. Pre-qualification for ESS, troubleshooting, and small scale ESS programs would all benefit from high air flow, high change rate testing in this compact design. This series can accommodate up to six product drawers from our standard ESS systems. Other features include non-CFC/HCFC design, and wide variety of control systems, refrigeration system sizes, and product

ESPEC makes rain and spray testing easier by offering a standard chamber capable of published and OEM proprietary test methods. The standardized design can be configured for the rain/spray tests you need, eliminating the guesswork in buying a chamber. The system is based on the JIS/SAE specification requirements, and can also accomplish individual automaker’s tests, as well as electrical-enclosure tests. 

Our Design:

• ESPEC's modular design allows you to add on additional features, depending on the number and type of tests required. One possible choice is to integrate the spray system with a regular temperature and humidity chamber to save money and floor space, while also creating an opportunity to simulate actual operating conditions your product may experience. 
• Our system uses multiple control solenoids to vary the water's spray volume/pressure. A holding tank prepares the water to the desired temperature, if required. A pump ensures the water is delivered in the proper pressure range. 
• The water is fed to a motorized manifold that rotates the spray arms. Each spray arm has an adjustable valve to allow finer control of the spray.

Product Details:

• Stationary product shelf (a rotating shelf is optional)
• Water pressure regulators, gauges, and flow meters
• Special high-volume floor drain system to rapidly drain water out of the chamber
• Viewing window with wiper

Applicable test methods:

• IP Code / IEC standard 60529 "Ingress Protection"
• JSA JIS (Japanese Industrial Standard) D 0203 "Method of Moisture, Rain and Spray Test for Automobile Parts"
• SAE (Society of Automotive Engineers) J2245 "Recommended Practice for Splash and Spray Evaluation"
• SAE J575 "Test Methods and Equipment for Lighting Devices and Components"

Optional/additional test capabilities:

• Temperature/humidity controlled chamber
• Water recirculation: Allows re-use of the treated rain water
• Water conditioning: Allows the water to be cooled (5 to 20°C) prior to spray
• High pressure spray: Adds capability to meet car wash test requirement
• Drip grid: Adds capability to meet drip test requirement
• Rotating table: Rotates the sample for full exposure to spray

Product Details:

ESPEC North America builds dozens of walk-in chambers every year for top companies testing automotive, electronics, communications, aerospace, and other products. Drive-in chambers for automobiles are one of our top specialties. Stability walk-in rooms are another specialty, designed for light-duty testing or long-term steady-state evaluation of pharmaceuticals and other products. 

Panelized Chamber/Room:

• Our panelized walk-in chambers use urethane-foam panels that lock together with cam latches. 
• This is the same construction used for walk-in coolers in restaurants and supermarkets, but of a higher quality.
• The panels we use have a stainless steel interior skin to be stronger and impervious to extreme conditions. The seams between panels are carefully sealed to protect from leaking that may affect performance or damage the panels. Doors and windows have embedded heaters, as well. 

Temperature and Humidity Control:

• ESPEC has standard air conditioning systems, called Modular Air Plenums (MAP). 
• These MAPs are designed with the proper heating, refrigeration, and humidity control to achieve your desired performance and capabilities. 
• The MAP simply rolls-up to an assembled panel chamber to complete installation. 

Easy-to-use Programmer:

• In addition, the P-300 Touch Screen Controller makes running an ESPEC environmental test chamber a breeze. 
• The full-color, touch-screen interface is remarkably easy to use and understand. 
• The P-300 Touch Screen Controller can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB/LabView.
