The systems from the Blaubeuren-based manufacturer, with widths up to 508 mm and lengths up to 640 mm, already meet this requirement in their basic configuration. Furthermore, optional software and hardware adaptations enable fully automated, customized machining of extreme sizes.
As the complexity of electronic systems increases, so does the number of logic modules required on a board, in combination with power modules; the result is increasingly larger printed circuit boards. Innovative large-board options for Rehm's Protecto series dispensing and coating systems enable the reliable coating of these large boards.
Even with the basic equipment of the Protecto systems, printed circuit boards with a maximum width of 508 mm or a length of 640 mm can be processed. While the largest processing area is reserved for the outermost applicator, there is a correspondingly smaller path for the up to three subsequent applicators. However, this still covers a substantial minimum dispensing area of 400 mm x 508 mm, even with a full complement of equipment. Rehm Thermal Systems offers specially tailored solutions for special applications with even larger printed circuit boards. Not only can the processing range of all applicators be expanded via software, but the infeed and outfeed of the systems can also be enlarged almost at will thanks to a backpack design that accommodates significantly larger printed circuit boards. The exact configuration of the potential work areas is decided in collaboration with the customer and is based on their individual requirements.
Large components are used in a wide variety of applications and fields. In lighting technology, for example, LED segments up to 1.5 m long are used, which cannot be automatically coated without a large-board option like the one offered by Rehm with Protecto. The same applies to solar inverters and the production of special films for battery manufacturing. The 5G industry, power modules for wind turbines, and charging stations for gas stations also rely on large-format printed circuit boards. With the automated processing of these components within a self-contained system, Rehm Thermal Systems offers a tangible advantage to manufacturers and suppliers.
The Protecto series from Rehm Thermal Systems provides safe, automated processes and precise results for applying a wide range of materials. Up to four applicators can be used simultaneously, offering users a broad range of options: In addition to dispensing, this includes the ability to create freely definable three-dimensional housing shapes with a single application, the immediate curing of UV varnishes, and the encapsulation or bonding of different materials.

Automatic coating and dispensing of large-format printed circuit boards
Rehm Thermal Systems' ProtectoXP and ProtectoXC dispensing and coating systems protect electronic components from harsh environmental influences such as humidity, corrosion, chemicals, dust, and vibration. As these components in high-voltage power electronics—especially in the areas of 5G technology, electric mobility, and renewable energy—increase in size, the industry's need for new coating solutions for large components is also growing.
