Axiom Test Equipment, an electronic test equipment
rentals and sales company headquartered in North County San Diego, has published
a blog post entitled "Turn on the Temperature with Thermal Test Systems," explaining
the need to properly evaluate product function across the full range of expected
ambient temperature conditions. Doing so helps guarantee favorable customer experiences
and online ratings, as well as reduces costs of warranty service.
Turn on the Temperature with Thermal Test Systems
Electronic device performance is sensitive to
temperature, with most electronic devices and components specified according to
operating and storage temperature ranges. Those ranges differ according to the type
of component and application, with electronic products for industrial and military
applications usually characterized over wider temperature ranges than commercial
electronic products. Thermal test systems provide convenient ways to reproduce the
temperature ranges that a device might encounter under actual operating conditions,
but they also help bring temperature control to a device under test (DUT) as the
means of performing thermal shock testing and accelerated lifetime testing. Selecting
the best thermal test system for the job is simply a matter of understanding the
thermal test requirements for an application and how to best deliver them.
Many electronic device failures are related to thermal issues, such as solder
joints and other electronic junctions that exceed maximum safe operating temperatures.
Printed circuit boards (PCBs) and other electronic materials have different coefficients
of thermal expansion (CTEs) which describe how they expand and contract with rising
and falling temperatures, respectively. For example, PCB assemblies consist of layers
of dielectric substrate materials and metal conductors, such as copper, with surface-mount-technology
(SMT) and other types of miniature packaged components attached to conductive circuit
patterns. Each material has unique thermal characteristics and expands and contracts
in different ways as a function of temperature, resulting in stress points at the
interfaces of different materials. Thermal testing is often used to check the reliability
of plated through holes (PTHs) and solder joint connections in PCBs to determine
Thermal cycling through a temperature range at a prescribed rate of change in
temperature is also used to perform accelerated life testing of electronic devices
and components, speeding failure mechanisms in a DUT to better understand how to
improve and/or optimize ...

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
