Casting resins protect high-quality electronic components against undesirable penetration by dirt and moisture. Precise and reliable dispensing technology is essential for the automatic application of these resins. bdtronic GmbH, a company located in Weikersheim in Baden-Württemberg, is one of the world’s leading suppliers of dispensing systems, including complete systems for automating the assembly and production of electronic components. bdtronic has now worked with Festo on a groundbreaking project to expand its product portfolio. The new mini-dis from bdtronic, based on the compact handling system YXMx, opens up another field of application in the front-end processing of electronic and telecommunications products. The integrated CECC-X controller allows curved travel paths, thus making it possible to produce even complex casting patterns. Designed as a space-saving and flexible desktop application, the new complete solution from Festo facilitates cost-effective production of extremely short production runs.
Precision and reliability
The microdispensers and the mini-dis are used with semiconductor products and circuit boards, with the electronic components of numerous automotive modules and sensors, in medical technology and with smartphones. The mini-dis processes single- or two-component materials with an epoxy, polyamide, silicon or acrylate base as well as soldering pastes in the µl range. Across the world, several thousand different casting materials are used.
When it comes to the dispensing technology itself, two criteria are especially important: precision and process reliability. To achieve these, bdtronic works extremely closely with its clients’ experts. In the company’s own application and technical centre, each product is extensively tested to check the interaction between the casting resin, the dispensing technology and the components to be processed. One of the greatest challenges in the dispensing process is the optimum preparation of the casting resins. These must first be homogenised and then evacuated. This avoids even the smallest air pockets.
