Eurobond Adhesives has launched a new Elecolit® range of silver-filled, epoxy-based, one and two-component conductive adhesives for bonding electrical and heat-sensitive components. The adhesive cures at room temperature, have a long pot and storage life and can be applied using dispensers, jets or screen-printers.
New Hardener Systems for Bonding Heat Sensitive Components
Innovative hardener systems develop ‘cure’ within minutes and can be used to connect heat sensitive components to printed circuit boards, waveguide plumbing, hybrid circuit assembly, connecting ground wires to components, making conductive tracks or pathways and bonding discrete devices and hybrid circuits. Other applications include bonding conductive paths in heated car windscreens and mirrors, RFID applications, bonding batteries to foil/film, bonding flexible film LCD’s to hard FR4 boards, circuit track repairs, populating PCB’s, and so on.
Elecolit® 325 - Silver-filled Epoxy Adhesive
Elecolit® 325 is a two-component pure silver-filled epoxy adhesive that combines the excellent adhesive properties of the epoxy with the electrical conductivity of pure silver. It is easy to use because equal amounts of Part A and B (resin and hardener) are mixed and has a 1 to 2-hour pot life. Elecolit® 325 may be processed with dispensers, stamps or by screen printing. Adhesive curing occurs at room temperature. Increasing the temperature speeds up the curing process. Elecolit 325 also has excellent gap-fill properties.
Applications for Elecolit® 325 include:
-
Connecting heat sensitive components to printed circuit boards.
-
Bonding waveguide plumbing and hybrid circuit assembly.
-
Replacing metal solder where temperature or convenience is required.
-
Chip bonding for discrete devices and hybrid circuits.
Elecolit® 414 - Polyester-based Electrically Conductive Adhesive
Elecolit® 414 is a polyester-based, electrically conductive ink, coating and adhesive suitable for application by stamping, screen printing, dipping and syringe dispensing. Elecolit® 414 is formulated to provide exceptional conductivity when cured at low temperatures. The adhesive is resistant to flexing and creasing.
Applications for Elecolit® 414 include:
-
EMI/RFI shielding of polyimide flexible circuits.
-
Polymer thick film circuitry, membrane switches
-
Electrical attachments for surface mounted devices and anode coatings for tantalum capacitors.
Elecolit® 3653 – Solvent-free Silver-free Conductive Adhesive
Elecolit® 3653 is a silver filled, highly flexible solvent-free conductive adhesive. The flexibility of the cured adhesive makes it ideally suited for applications that involve vibration or thermal shock. The product can be dispensed or processed with stamp, print or screen print. Elecolit® 3653 is a one-component product, and thermally curable in short time frames.
Elecolit® 342 - Silver-filled Electro Conductive Adhesive with Plastic Bonding Properties
Elecolit® 342 is a 1K silver-filled electrically conductive coating with excellent glass, metal and plastics bonding properties, that cures to a hard film in the air. The adhesive can be processed with brushes, dispensers or needle transfer. Electrical conductivity is excellent.
Elecolit® 342 has excellent glass bonding properties and is being used to create windshield defroster contacts in cars, or RFI shielding of electronic housings. After extended storage periods, the product must be re-homogenized as the adhesive sediments naturally in low viscosity resins.
