Dehumidification in storage facilities for printed circuit boards
Preventing corrosion and electrostatic charge of printed circuit boards
Duoventic: individual vernier adjustment of humidity level and volumetric flow
When storing printed circuit boards humidity can lead to electrostatic charge and patina formation or corrosion. Particularly suited for dehumidifying the PCB storage space are the mobile adsorption dryers of the TTR series – just as well as for other operating sectors in the electronics and semiconductor production.
In the electronics and semiconductor industry the requirements relating to the performance of dehumidifiers are especially high. In this sector, it is not only important for metals to be protected against corrosion and patina, but coatings too must not be allowed to swell. In addition, printed circuit boards can become charged when they are stored in too humid surroundings. Investing in easily controllable dehumidifiers with a steady performance is absolutely recommendable, particularly in PCB storage facilities, and pays as quality assurance measure.
The stationary and mobile adsorption dryers of the TTR series – by use of one of the three variations of the TTR functional principle – ensure a high dehumidification performance while simultaneously keeping the energy consumption low. Both mobile adsorption dryers marked with "D" for the Duoventic air volume regulation, TTR 400 D and TTR 500 D, provide maximum flexibility when adjusting the required amount of dry air. Owing to the innovative Duoventic air volume regulation both fans of the separate air circuits can be controlled independently via an infinitely variable electronic regulation. This enables an individual vernier adjustment of humidity level and volumetric flow of the required dry air and thus a precisely controlled percentage of relative humidity in the PCB storage space.
Reliable measurement technology and data loggers "made in Germany"
The electronics and semiconductor industry has to depend on extremely reliable measurement technology to keep a single-figure relative humidity value constant – particularly in PCB storage facilities. Trotec, for instance, supplies the thermohygrometers T210 and T260. Furthermore, the data loggers of the MultiMeasure Professional series, DL200H or DL200X, manufactured in Germany, provide manifold opportunities for tamper-proof long-term measurements during dehumidification.
Make use of our best practice industrial services
Since every industrial undertaking has characteristic process flows, installations and facilities, every air treatment solution demands case-specific device configurations. All in all, the combined effects of air currents, humidity conditions and temperature fluctuations are often hard to calculate on a purely theoretical basis, e.g. in airlock areas or on conveying paths. The consequence: Unnecessary additional costs due to an overestimated demand or – even worse – solutions not working sufficiently in real life.
You can count on our experts
In order to precisely calculate the demand in the industry and to develop tailor-made concepts for climate conditioning experienced climate specialists are needed. Rely on our team of experts as well as the industrial services: We analyse the individual requirement situation with you present on site, determine the specific demand for devices and develop a tailor-made project solution right up to the exact positioning of the devices.
Before the planned stationary units are installed, our service team first works with mobile versions of the drying units as part of a trial run. These can be put up without any difficulty or the need for structural changes.
During this validation phase we document all relevant climate parameters such as air temperature, relative humidity, dew point or flow rate for a final optimization of the requirement calculation.
Trotec is the only provider of this advantage:
Thanks to the unique option of non-binding trial operation you will invest solely in solutions which have verifiably proven their worth in everyday operation meeting your individual on-site requirements. The stationary units will not be ordered until you are fully satisfied with our concept. The only costs incurred consist of an inexpensive hiring flat rate for the time of test operation.
