Dehumidification in storage facilities for printed circuit boards
Preventing corrosion and electrostatic charge of printed circuit boards
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.
Duoventic: individual vernier adjustment of humidity level and volumetric flow
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.
Climate conditioning in PCB storage facilities: make use of our industrial services
For the electronics and semiconductor industry the Trotec Group not only supplies dehumidifiers and measurement technology, but also technically and economically ideal solutions for climate conditioning in all areas where printed circuit boards are stored or produced. Our specialists in the industrial services team calculate all climate parameters and recommend the suitable devices. Moreover, we have mobile units on offer which can be used to test the planned dehumidification in advance. This way, you can be sure that the proposed solution actually works.
Upon request, we will readily produce tailor-made desiccant dehumidifiers as special models “made in Germany” perfectly geared to your needs, e.g.:
- TTR industrial desiccant dehumidifiers with hygienic design
- TTR industrial desiccant dehumidifiers for PWIS-free dry air
