Along with partner Asys, Super Dry Totech will feature its broad range of dry storage solutions for moisture sensitive devices at this year’s SMT. Visitors will find out how the low humidity desiccant cabinets can protect a wide range of products against defects caused by humidity. Designed to exceed IPC/JEDEC J-Std-033C, the company’s cabinets can dehumidify to less than 0.5 % RH. This qualifies them not only for unlimited safe storage, but also means they can safely remove moisture, thus resetting floor life without oxidation, even at ambient temperatures.
There is a growing trend in the electronics industry of increasing component lead-times, whilst reducing development cycles make it increasingly necessary to hold extra stocks on the operational side. Warranty management, and last time buys are other reasons for growing requirements for specialised storage services. For component distributors and companies that do not wish to make the investment in capital equipment, or may be looking for a flexible and scale-able off-site warehousing solution, the company’s outsourced Long Term Storage Service, LTS², is the alternative value-added service, helping to overcome challenges that go beyond moisture and oxidation control, including the need to arrest intermetallics without inducing tin whiskers.
Keeping safe storage in-house is a possibility with the “Dry Air Only” solution. After carefully defining the exact environment required, including humidity, temperature, recovery time and traceability, the end-user pays only for the dry air – as it is consumed.
Amongst the equipment on display will be the MSD series, a modular drying cabinet that adapts to your storage and drying requirements. Incorporating the U5000 Series Dynamic Dry Unit, the basic MSD can be expanded in the field without the need for additional dry units. This can result in a cost saving of more than 50 %. Performance is maximized and regeneration times reduced through closed loop control.
XSDR ‘Floor Life Reset Cabinets’ brings process control to multiple batch management of moisture sensitive devices. Using sensor technology and software, the XSDR Series Reset Cabinets can independently track the timing of 10 separate batches of components being reset at the same time per chamber. Two separate chambers, each with their own dry-unit and heater enable two different temperatures to be applied in the same cabinet, dehumidifying to less than 1 % RH.
The XSDC series of cooling cabinets is ideal for numerous applications where chilling is required, keeping all substances at a precise safe operating temperature with 4.0 traceability. With a stable internal temperature of 2 – 20 °C with minimal energy expenditure, the cabinets aid in the slow-down of inter metallic growth.
Other exhibits include the company’s fully automated, robotically controlled, component handling and storage system, Dry Tower. Incorporating MSD technology and WMS-system integration capabilities, they are capable of automatically managing tens of thousands of reels and trays and are modular for all mix and volume manufacturing scenarios. Live at the show, at the Asys stand, will be the integrated Autonomous Indoor Vehicles (AIV). The driverless transport systems can manoeuvre autonomously in production and feed the required material to the line, including magazines, component reels, paste, and cleaning paper.
The Super Dry XSDC long term storage cabinets have an outstanding performance for long term storage of moisture sensitive components and PCB’s. The U-5000 series dynamic drying unit reaches very reliable, low humidity values of 5 %RH and automatically regenerates when necessary whilst the powerful cooling unit maintains a constant temperature as low as 10 °C below ambient.
The software tool, MSL 2.0, enables manufacturers of any size to maintain control of their component inventory, and particularly their moisture sensitive devices. Whether integrated with existing ERP and MES systems or used in a standalone fashion, real time monitoring and traceability of moisture sensitive inventory helps manufacturers on the path to achieving their 4.0 goals.
For situations when storage under strictly defined conditions is necessary, the company is working with ASYS Cleanroom solutions to offer the Considus Dry Storage Systems. These cabinets give the optimum protection for highly sensitive components and assembly parts. Three different dehumidification technologies are available to achieve a stable and dry atmosphere:
- Adsorption dehumidification: controlled drying and circulating of air with a powerful adsorption drier.
- Nitrogen dehumidification: controlled feeding of nitrogen.
- Compressed-air dehumidification: Controlled feeding of compressed air.
The Cleanroom technology offers traceability software for monitoring and documentation of the component status, MSL level and relative humidity.
