Structural heat sink bonding of battery cells Battery cells for low-voltage systems are often mechanically connected to a housing or a heat sink, requiring additional gap fillers or thermal pads for heat dissipation. DELO’s structural TCAs (thermally conductive adhesives) allow for battery cells to be bonded into the housing while simultaneously connecting them to the thermal management system, efficiently dissipating heat. This simplifies the production process, eliminating the need for gap fillers or thermal pads. Assembly process ` Structural bonding of battery cells to housing `...

Structural heat sink bonding of power electronics When connecting heat sinks to PCBs, thermal conductivity is key. Our portfolio includes one-component epoxy adhesives with thermal fillers that offer 50 percent higher thermal conductivity when compared to our products for heat sink bonding of battery cells (see p. 5). Users also benefit from variants with a high glass transition temperature (Tg) that are suitable for high-power applications. For temperature-sensitive components, we offer thermally conductive adhesives that can be cured at temperatures as low as +60 °C. Assembly process `...

Electroconductive bonding With billions of RFID chips assembled annually using DELO’s products, we have transferred our electrical conductivity expertise to battery electronics. DELO’s reliable anisotropic conductive adhesives (ACA) connect electrical components and ensure insulation between bumps, with no short circuiting. Our large ACA portfolio offers different particles for a variety of material properties and conductivity requirements. DELO also offers non-conductive die attach adhesives. All of our adhesives are suited for high-speed thermode curing, allowing for cycle times as low as...

Chip and PCB encapsulation In battery applications, chips, SMD components or larger parts of the PCB need to be protected from mechanical and chemical influences. A high temperature resistance, as well as compensation of thermal stress between the PCB and its components, is required from encapsulants and casting compounds. For these applications, DELO has a broad portfolio that fulfills typical automotive requirements. We offer a variety of assembly process options, including different patterns of dispensing like glob top or dam & fill to give freedom of design. Our curing processes are...

ONSERT combining screwing and bonding ONSERT technology combines bonding with elements of fastening. The fastener, equipped with a transparent, polycarbonate base plate, is combined with a screw. By using light-curing adhesives, the base plate can be bonded to many surfaces within seconds. This fast and reliable technology is well established in the aerospace and automotive industries. It is used for cable holders or attachment components in lightweight electric vehicles. DELO has adopted this technology for battery assembly, providing a smart and flexible solution for the fixation of...

LED curing lamps DELOLUX LED lamps are the leading technology in fast curing. They allow optimal adjustment to any adhesive used. These lamps offer high energy efficiency and can achieve a lifetime of more than 20,000 hours, which is significantly higher than that of conventional discharge lamps. For optimal curing, lamp wavelengths are adjusted to the adhesive properties. The lamps stand out for their low power consumption. Their power can be set individually. All these additional features guarantee costefficient production processes. Fast Short cycle times, high output and reproducibility...

Microdispensing jet valves Adhesive, application and desired degree of automation – these factors play a key role in the selection of suitable dispensing equipment. DELO’s dispensing technology is precisely adapted to its high-tech adhesives to enable optimal production processes. Users benefit from cost-effective adhesive processing that can be integrated easily into the dispensing process. Jet systems must be compact and operate quickly and precisely. Precision is necessary for the accurate and reproducible application of tiny adhesive quantities, while speed allows fast processes, and a...
