Temperature and Humidity Control

Mekko “active desiccant” technologies Drying and storage cabinets

Our cabinets are used in a wide variety of applications involving moisture removal and dry storage. The main sector to install Mekko cabinets is the electronics assembly industry, where components and brackets must be protected from the damaging effects of moisture.

Mekko complies with IPC/JEDEC J-STD-033, which recommendations for handling details, packaging, shipping and use of moisture-sensitive/reflux sensitive surface mount devices.

If moisture is absorbed into the environment by the surface mount components, then the components are exposed to high temperatures, such as in solder reflow ovens (convection, infrared, IR/convection, vapor phase, hot air reprocessing tools), then the absorbed moisture will expand rapidly, causing stress on the internal device. The resulting stress can cause internal or external cracking, peeling and internal corrosion.

Eliminate popcorning and micro-cracking of ICs and BGAs during soldering by using active component adsorption and storage drying, rather than baking.

Benefits of the Active Desiccant system:

•  No need for anti-moisture bags, nitrogen or compressed air.
• Less complicated than baking: reduces oxidation.
• Can use low temperature packaging.
• Suitable to meet IPC/JEDEC J-STD-033C standard.
• Internal temperature and humidity dials included.
• No “off” time. Desiccant will always be absorbing moisture.
• Desiccant is permanently self-healing at the molecular level.
• Fast recovery time after door opening (2 minutes).
• Very accurate humidity dial: +/- 1% relative humidity (usually +/- 3% in our competitors!)
