When is it better to use a chamber, and when is a platform the best
choice?
Sigma Systems
thermal platforms have a very flat contact surface and are
ideally suited to condition devices with equally flat conductive surfaces
and a low vertical profile. Platforms offer ease of access and very fast
performance. Heat is transferred to/from the unit under test by conduction
which is faster than the convection method used in chambers. If the heat
transfer can take place through one flat surface, a Sigma Systems thermal
platform may save money and space and allow much faster throughput. Options
such as the acrylic covers available from Sigma Systems, can provide a
degree of protection from the room atmosphere.
If your device has an irregular geometry, large heat dissipation, or tall
profile, the turbulent convective airflow of a Sigma Systems
temperature
chamber is better suited for your application. Chambers can be configured to
process larger batches of components either in stacks or on racks. If all
around gradients are an issue, the homogenous environment of a Sigma Systems
temperature chamber will be the best choice.
