Qualmark QFusion 300 HASS Chamber (LN2)
Qualmark’s QFusion™ (patent pending) HASS Chamber ushers in a new era of product reliability management during the manufacturing process. By fusing accelerated stress testing and Burn-in into one powerful system, Qualmark has engineered breakthrough technology that incorporates the best of traditional and accelerated production stress screening.
Manufacturing advancements and the increasingly complex attributes of today’s electronic devices often require more robust test methods than those traditionally used in order to successfully detect flaws that can be introduced during the production process. And gone are the days where lengthy Burn-in cycles can be tolerated before fielding product. Business is happening faster than legacy test technology can accommodate QFusion is designed to place the correct tool in the production facility for enabling faster and more effective monitoring of high-volume production of electrical and electromechanical products.
The Qualmark HASS System features six separate repetitive shock/vibration tables and rapid thermal cycling in an extremely efficient, quiet system with a small footprint. Its thermal performance can slash traditional burn-in times by half and can reduce utility costs by 40%.
The Qualmark HASS System delivers advanced process screening capabilities engineered specifically for performing HASS/HASA. A unique six-compartment configuration provides consistent stresses to all test positions. The high-speed airflow from the thermal system maintains uniformity while reducing the time to reach and stabilize at temperature. The QF Manager control software features an easy to understand user interface, cross-control connectivity via TCP/Ethernet, and closed-loop thermal and vibration control.
We specify, quote, install and service these machines Australia-wide.
Next Generation Burn-In
The Qualmark HASS System has introduced the next generation of burn-in technology — accelerated burn-In. Its thermal performance can slash typical burn-In cycle times by half, and its ergonomic, multi-table configuration allows for fast loading/unloading. Additionally, Qualmark HASS System efficient burn-In technology can reduce utility costs by up to 40%-60%. The Qualmark HASS System provides dual capability in one system — accelerated stress testing and accelerated burn-In.
Our experts work with the Qualmark services team to design and fabricate product fixtures suitable for manufacturing use. The process of ensuring each product sees the same amount of stress throughout testing is complex and requires specialist equipment and an understanding of fluid dynamics.
6DOF repetitive-shock table
Simultaneous excitation at multiple frequencies for testing complex assemblies
Patented pneumatic hammer/table design is lubrication-free and valveless
Quiet operation without external cooling requirements
The table is field-adjustable for resetting to original PSD levels, ensuring consistent performance. (Adjustment included in our preventative maintenance agreement.)
Cooling System
Vacuum Jacketed (VJ) liquid nitrogen (LN2) valves and manifold.
Proportional control and valve system for maximum LN2 efficiency and consistent temperature control, while reducing two-phase (gas/liquid) states that cause problems in traditional on/off solenoid-based control.
VJ eliminates condensation, dripping water, OSHA safety concerns, and energy loss compared to other insulation methods.
Efficient, economical LN2 usage with either low-pressure Dewar tanks or higher pressure Permacyl and bulk tank systems.
Chamber Design
Stainless steel interior, painted exterior, with two full opening doors (one door on T1.5/2.0 models)
High-velocity airflow for improved product temperature change rates.
Two-position table for flexibility to test taller samples, improved ergonomics, and less LN2/electricity usage for smaller test items. (except T1.5/2.0)
Advanced chamber insulation combined with our low-noise hammers results in very quiet operation, even at maximum vibration levels.
Adjustable feet for leveling unit (stand options for T2.5/3.0 models)
Control System
Microsoft Windows system with Labview based operation and PLC-based controls
Programming, operation, and datalogging for vibration/thermal profiles.
One accelerometer for table control (three additional inputs available)
Two thermocouples: one for product, one for air (four additional inputs available)
Eight event relays for external controls
Optional Q-Link or Qualview software tools for ATE integration and other remote connections.
Optional integrated spectrum analyzers and data acquisition systems.
Liquid Nitrogen Vacuum Jacketed Piping
We work with your facilities teams to specify, design and supply the pipework for your HALT chamber.
Keep-full devices are essential to ensure optimum control of the chamber - preventing gas from creating PID disturbances.
Our pipe is made in the USA by Midwest Cryogenics and is simple to install and maintain.
Exhausts, airlines, and all other chamber utility requirements can be supplied.
External control and safety valves can be fitted to shut off supply in the event of a leak.
Safety Systems
We understand the risks of Liquid Nitrogen and have decades of experience planning installations and the safety mitigations that go with them.
Control panels inside the room are tied to gas detectors which can automatically shut the chamber supply line down at the source.
Control valves can be placed at key points along the route to ensure sections can be isolated through key facilities.
Additionally the control panels can be tied to facility supply and exhaust systems to increase air flow before critical alarms kick in and take the building down.
