Chamber vs. Platform

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.
