20 Years Totech Europe

It’s the year 2004, the use of ‘lead’ in solder alloy is banned due to EU legislation, Jos Brehler, CEO of Totech Europe, starts his company with the knowledge that, by eliminating lead from the solder alloy, the moisture related issues increase dramatically due to the increase of pressure on the parts by raising the reflow temperatures for this new alloy. As a result, components which hold too much moisture during reflow will cause defects due to Popcorning (vaporizing moisture creating micro-cracks), which can lead to failure of the entire assembly. Long story short, the solution to prevent these defects, a dry and conditioned storage environment for MSL components. The birth of the first Dry Cabinets in Europe is a fact.  The ambition to become the specialist in Dry Storage Solutions grew from early on. That is why in 2007, Totech Europe changed from being a sales company to a product development and production organization! To become even stronger in the Automated Dry storage solutions, Totech Europe joined as a proud member of the ASYS Group in 2017. Together with ASYS Group we offer a unique product portfolio for manufactures in many industries. first to know!  Today we are ‘Connecting safe storage to Smart Manufacturing’. Our vision is, to be the leading supplier of Sustainable Dry Storage Solutions for electronic manufacturers worldwide. When we look back at the last two decades, we see a bright future ahead! To celebrate the first 20 years of Totech EU we gave our website a big update. Hopefully you like what you see!

Thermally Managing Intermetallics

The storage of moisture sensitive (electronic) components and materials are problematic. Manufacturers with Long term Storage Requirements face additional obstacles. Due to rapid changes in packaging design, material and a very high demand for electronic components (consequently a shortage of semiconductors in all industries), companies find themselves forced to purchase additional quantities of components in order to guard against the impact of component obsolescence on their final product designs. This in turn creates an issue of long term inventory storage. Product lifecycles have become very short with new models being released sooner than ever before. However, many manufacturers in industries including automobiles, aviation and avionics, military and railway must guarantee the availability of replacement parts including PCBs for ten or even twenty years. This demands the advance purchase and extended storage of components and materials. Further complicating the problem is that most components cannot be stored for more than a few years without very special handling procedures. After long-term storage, components and circuit boards are often no longer solderable, due to oxidation caused by the oxygen of the air (oxidant) and the humidity (electrolyte). However, if the humidity, which forms an invisible water film of few atomic layers on the surfaces, is lowered below 5% RH, this corrosion process is stopped. At the same time, other negative effects due to moisture absorption are also avoided. Intermetallic compounds form when two unlike metals diffuse into one another creating species materials which are combinations of the two materials. Intermetallic growth is the result of the diffusion of one material into another via crystal vacancies made available by defects, contamination, impurities, grain boundaries and mechanical stress. There are a number of locations within the electronic package where these dissimilar metals are joined. These include die level interconnects and wire bonds, plating finishes on lead frames, solder joints, flip chip interconnects, etc. Growth of intermetallics during the storage period can occur and reduce the strength. Intermetallic growth rate is strongly temperature-dependent and doubles for each 10°C temperature increase. This aging process can be slowed by appropriate cooling. However, the risk of whisker formation of tin alloys increases with decreasing temperature. Studies and practice have shown that a storage temperature of 13-14°C is optimal. The XSDC-1412-55 cabinet from Totech Europe will help you avoid risks as mentioned above. Find out more about the XSDC long term storage Dry Cabinets.

Zeolite Technology

People refer to Desiccant Cabinets, and Dry Cabinets, and Desiccant Dry Boxes…but not everyone is familiar with the actual desiccant technology that we employ.  Unlike clay or silica, we use a crystal known as Zeolite.  It is a molecular sieve — that is to say, the size and shape of its structural openings are that of H2O molecules.  And those water molecules are literally sifted from the air inside the cabinet.  The desiccant is never touched by operators, and it never needs replacing. Read on for our more technical explanation: Zeolite molecular sieves are crystalline, highly porous materials, which belong to the class of alumino silicates. These crystals are characterized by a three-dimensional pore system, with pores of precisely defined diameter. This diameter is in the dimension of the size of molecules such as water, CO2 and H2S. The pores can be adjusted to precisely determined uniform openings allowing for molecules smaller than its pore diameter to be adsorbed whilst excluding larger molecules, hence the name “molecular sieve”. The different pore sizes of synthetic zeolites open up a wide range of possibilities in terms of “sieving” molecules of different size or shape from gases and liquids. Zeolite molecular sieves are purely synthetic materials and are characterized by the following properties: –Selective adsorption due to the uniform pore size of the zeolite structure. –High adsorption capacity for polar substances at low concentrations Molecular sieves are manufactured by crystallisation from aluminium hydroxide, sodium hydroxide and waterglass. Under carefully controlled conditions, the crystallisation process produces the required sodium alumino silicate structure. The formed zeolite crystals can then be ion exchanged to adjust the pore size. After drying, the molecular sieve crystals can either be processed to activated zeolite powder or a quantity of binder is added, forming the material into beads.  These beads are dried, calcined and finally screened to the required particle size prior to packaging. Zeolite Structure In addition, the pore size plays a significant role, allowing or prohibiting the entrance of molecules to the pore system. Selective Adsorption of Water and other Polar Substances The up-take of water or other materials in zeolites is called adsorption and functions on the basis of physisorption. The main driving force for adsorption is the highly polar surface within the pores. This unique characteristic distinguishes zeolites from other commercially available adsorbents, enabling an extremely high adsorption capacity for water and other polar components even at very low concentrations. The adsorption on molecular sieves is therefore dependent on the following physical molecular properties: Size and Shape: Molecules larger than the pore opening of the molecular sieve cannot be adsorbed, smaller molecules can. Molecular Polarity: Molecules with large polarity or polarisability can be adsorbed preferentially under identical conditions Of note is the high capacity of the Zeolite used by Totech even at low water concentration, allowing to dry to very low water contents. The molecular sieve can also retain its high capacity at high temperature, which makes it the optimal material if drying needs to be carried out at elevated temperatures. The adsorption process is fully reversible and of purely physical nature. The structure of the zeolite stays intact during the adsorption process (and its later regeneration), and dissolution effects like with other drying agents like calcium compounds cannot happen. How do Super Dry Dynamic Dry Units work? Our dynamic high performance drying unit U-5002, can achieve air moisture levels of under 0.3% RH, even at temperatures of 60°C. Unlike traditional technology, during cabinet door openings, air moisture levels barely rise above 5% and sink within a few minutes again to The desiccant is refreshed by heating and allows the trapped moisture to escape as vapor (H2O) through vents located at the back of the cabinet. Once refreshed the unit is ready to seal off the exterior venting, and re-open itself to the interior to continue dehumidification. Through a microprocessor the state of the drying substance is permanently monitored and compared with the input set point values. Only when the moisture content in the cabinet exceeds the absorption capacity of the drying substance, is the thermal regeneration started. The strength of this process in turn is fitted individually to the desired set point moisture in the cabinet. This has led to a drastic reduction of energy demand in cabinets which are infrequently opened. Often a regeneration of only 8 minutes suffices many weeks of component drying. In manufacturing environments, the regeneration behavior of the drying unit adapts itself dynamically to the needs of short opening cycles of the doors and frequent access. Through this, the availability and efficiency is improved considerably in comparison to traditional fixed regeneration cycles.
