I have always understood desiccant as being the material used in a desiccant pouch or other container that absorbs moisture.

A Drybox is a desiccator, a device used to remove moisture, with or without a heating option.

Thanks Dave,

Methinks a few misnomers were attributed to me unfairly, but that is OK as long as the discussion moves forward.



My recommendation, and I will change my response format on future posts accordingly, is as follows:

1. Cite the appropriate standard

    > Use IPC-1601, Printed Board Handling and Storage Guidelines, as the foundation document.

2. If it needs additional information, fill out a standards improvement form.

    > Provide context and data when available.

3. Clarify terminology used.  

    > This one is sometimes most important as the same term means different things in various points along the chain.  My perfect example is 'Panel.'  A lot of manufacturers use the term panel when they mean array and this conflicts with the PCB fabricators as the Panel is the Master or Shop Panel.  Also, for me a dry chamber is a desiccant (unheated, low humidity) chamber.  I think this is what caused the most confusion on this particular thread.
