Almit Technology is using Nepcon 2005 to show models from its newest range of Super Dry humidity control cabinets into the UK market Manufactured by Totech in Japan, the drying cabinets directly address increasing concerns over process errors resulting from high inherent moisture levels in stored components and subassemblies causing failures at higher lead-free solder temperatures

As a recently appointed principal distributor for the extensive range of Totech Super Dry cabinets across the UK and Ireland, Almit Technology is in a position to assist manufacturers combat assembly process failures in Moisture Sensitive Devices (MSDs) with its latest Super Dry cabinets - a range that comprises dozens of cabinet models, sizes and configuration.
Of particular relevance to the electronics manufacturing market are the Hyper Series and 02 Series.
Both deploy self-regenerating desiccant, widely regarded as the safest, most reliable, energy-efficient and virtually maintenance free dehumidifying technology.

Lead-free wire is kinder on soldering iron tips
A new formulation of Pb-free solder wire is designed to minimise the leaching of soldering iron tips and reduce the cost of tip degradation common at higher lead-free process temperatures.
Almit's Super Dry Hyper Series are configured with two powerful desiccant dehumidifier units that operate concurrently to deliver and maintain low humidity levels down to less than 2% relative humidity.
These models, available in three standard sizes, exhibit a superior humidity recovery curve and are ideal for applications where the door needs to be opened frequently to access the contents.
The Super Dry 02 Series features a single desiccant unit with enhanced air tight doors and offers dehumidifying characteristics down to 2% RH.
These eight standard models in the range are ideal for maintaining low humidity levels over extended periods (up to several days) in the event of power loss.
Moisture levels in components has become a key issue for electronics manufacturers with the introduction of higher wave and reflow solder temperatures required by Lead-Free processes.
Among the known issues is popcorning - a catastrophic failure caused by component packaging materials cracking under the internal pressure of trapped moisture turning to steam.
The IPC highlights such issues in IPC/JEDEC J-STD-033A, and determines that MSDs are considered dry if stored at less than 5% RH.
As a result, subjecting stored component and subassemblies to a dehumidifying process cycle prior to assembly, or storing them permanently in a low humidity environment, is becoming a widely adopted critical process step to help ensure manufacturing integrity and end-product reliability.
All Super Dry cabinet models provide ESD protection through stainless steel shelving, internal coating on all surfaces, conductive door glass and resistive earthing connections.
In addition, both Hyper and 02 Series cabinets can be specified in customer sizes.
