“Combining Kerafol’s high-performance thermoplastic elastomeric materials with X2F’s controlled-viscosity molding (CVM) technology delivers a higher-performance alternative to conformal coating, potting, and sealing of electronics, achieving superior environmental protection and heat dissipation while reducing processing times and manufacturing costs,” X2F said in a press release.
All electronics are susceptible to damage caused by environmental contamination, vibration, shock, electrostatic discharge (ESD) and thermal stresses. That’s why protective strategies are critical to ensuring long-term reliability. Traditionally, multiple methods have been used to address each mode of failure. For example, spraying a conformal coating onto a PCB protects electronics from dust, moisture, and other environmental contaminants, while filling the assembly with a potting compound enhances its mechanical strength and adds electrical insulation. As devices become smaller, faster, and more functional, thermal management solutions, such as thermally conductive pads, fillers, adhesives, etc., have become even more important for dissipating and distributing excess heat, preventing damage caused by overheating and thermal cycling. Addressed separately, each of these protective strategies adds time, complexity, and cost to a manufacturing process.
X2F and Kerafol have joined forces, creating a strategic partnership to deliver advanced protection for electronic devices. This collaboration ensures long-term reliability by safeguarding against contamination, vibration, shock, ESD, and thermal stresses, all in a streamlined, one-step process.
This comprehensive single-step environmental protection solution reduces complexity throughout the supply chain. It simplifies manufacturing, warehousing logistics, and production processes while enhancing long-term reliability. The partnership has introduced cutting-edge technology to the market, integrating high-performance thermal materials with CVM technology, providing manufacturers with cost-effective solutions that ensure high reliability in electronic systems.
Kerafol’s new silicone-free Keramold materials are soft and flexible, highly electrically isolating, thermally conductive and can be molded into complex geometric shapes, making them ideal for overmolding electronics. Additionally, these materials are easy to handle, process at room temperature and require no refrigeration, drying, pre-treatment or post cure.
The X2F CVM approach to overmolding electronics combines patented hardware, sensors, and software to control the viscosity of ultra-high-performance materials and optimize mold pressure. Heat is generated electrically for continuous temperature control, and a multi-step “pulse-pack” extrusion process is used to fill the mold. By continuously sensing mold cavity pressure and deploying its “pack-hold-and-repack” process, the company builds to the best mold pressure for the application. As a result, it can mold ultra-high-performance materials and complex geometries that were previously considered unmoldable.
“Our Keramold thermoplastic elastomers flow extremely well on X2F’s CVM equipment, wrapping the complex contours of components and PCBs. And because of its softness, when pressure is applied it conforms to surfaces unlike any other material in the industry, without damaging sensitive components,” says Wolfgang Hoefer, Thermal Products Division Manager at Kerafol.
“We are excited about this collaboration because it provides our customers a new approach for heat management in electronics that is far superior to conformal coating and potting in many applications.” says Mike Slowik, CEO of X2F.
