by Jim Greig, Global Sales and Marketing Manager Electronic Materials, LORD Corporation This is the question that most people consider first when planning to pot an electrical or electronic device. The conductivity is created by adding globs of silver to the mix, which touch each other and establish electrical connections after curing. Don't throw out expired gold epoxy, just ship it to Microwaves101 and we will dispose of it for you.... Conductive epoxy is most often used to attach electrical components, often is part of the critical back-side path to RF and DC ground as well as heat sink. Note that sometimes gold is used in conductive epoxy. Gold is more expensive, and has less conductivity than silver, so why would you want to use it? We are experts in aerospace adhesives, medical device adhesives, high-temperature adhesives and in fire-retardant epoxy and silicone. Storage temperature of epoxy can be at room temperature, but many types must be kept in a freezer or refrigerator. MAX MCR Electronic Grade Epoxy Resin -1.5 Gallon Kit Electrically Non-Conductive Potting Compound, Circuit Board Encapsulating, Embedding, Masking & Waterproofing, Opaque Black, Medium Set, Thin 5.0 out of 5 stars 3. This is especially true with new gallium nitride power amps, where that first critical interface should be a low thermal resistance. After curing, it has strong toughness, high bonding strength at the bonding site, impact resistance, and shock resistance. Since the epoxy … We offer resins for: Our epoxy systems go into huge range of insulation materials, with processing and performance benefits such as short cycle times. Epoxy and Bakelite ® Phenolic Resins for Electrical/Electronics Applications. It can be mixed and poured in volumes of more than a gallon at a time. Below you can view information on many of their products. Many MMICs are attached with epoxy, but before you do this you need to consider the thermal implications. The definition of epoxy is a two-part system where a resin is mixed with a hardener, which starts a reaction and produces a strong polymer. Epoxy is one means of attachment that is used in electronics, for many different problems. © All Rights Reserved. This kit comes standard black and is heat stabilized up to 130cel. (80/20) solder with limited exposure to temperatures at or above 300°C (for 30 sec. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. It features: A low viscosity. Its low viscosity is ideal for many potting, sealing, encapsulating, and casting applications. It turns out that gold-based epoxies are at least partially conductive before curing (silver-loaded is not) and this property can provide a means for tuning microwave circuits with a tiny paint brush. Epoxy and acrylate resin based sealing and molding compounds are often used in … From coatings to transportation and energy to construction, we’ve been enabling progress through Responsible Chemistry for over half a century, Chemical Resistance and Secondary Containment, Primers, Sealers and Waterproofing Systems, Can, Coil and General Industrial Coatings, Protective, Marine and Shipping Container Coatings, Railway, Motorcycles and Specialized Vehicles, Cabinets, Countertops and Flooring Laminates, Epoxy Resins, Curing Agents and Modifiers, Semi-solid, Solid and Powder Grade Resins, Construction and Infrastructure Adhesives, Particleboard and Medium Density Fiberboard, Agricultural, Construction and Earthmoving (ACE) Equipment, Truck and Bus. Feature of epoxy for electronics. We provide customized electronic potting products according to customers' applications. If it seems to be too good to be true, it is. MG Chemicals offers a wide range of epoxy potting compounds for protecting printed circuit boards and electronic devices. $135.05. Print PDF. Wärmeleitende Epoxid-Kompounds für Elektronik (Thermally Conductive Epoxy) (8) Wärmeleitende Schmiermittel und Pasten für Elektronik Thermal Greases (7) Wärmeleitende Klebstoffe Thermally Conductive Adhesives (4) Epoxidharzmasse für Elektronik Epoxy Potting and Encapsulating Compounds (14) Polyurethane Potting Compounds (3) Why it doesn't pay to pot. Electrically conductive epoxy is used in attaching all manner of parts in a hybrid microcircuit, including MMICs, silicon ICs, passives such as resistors, capacitors and inductors, and thin film networks. NC epoxy is often used as the final staking for big parts such as electrolytic capacitors. Even explosion-welding has been used in the quest to join two dissimilar substances together! 2021 Microwaves101.
