Thermally conductive adhesives are thermally conductive products designed to offer effective thermal management in heat-generating components, combined with effective bonding power to join components. Henkel’s LOCTITE® range of conductive adhesive for electronics offer strong component and PCB interconnections for on-demand, long-term, and reliable performance. Our broad portfolio of electrically conductive pastes is formulated using a variety of base chemistries including acrylate, epoxy, and silicone platforms, each of which is designed to provide manufacturers with choice and flexibility for varying requirements. This pertains to electrically insulating adhesive i.e. the electricity must not be conducted. Many potting and encapsulation applications require an epoxy glue with high dielectric strength. An unfilled epoxy ideal for fast-curing applications: 2 minutes at 150°C (or thermode cure in 6 seconds at 180°C). Very high die shear strength of 210 Newtons. Certain temperature-sensitive electronic components cannot be soldered because the intense heat of liquid solder and the soldering iron can cause damage to the component. This type of application calls for an electrically conductive adhesive that can be used instead of solder. PCBs with components attached to both sides can also benefit from using an electrically conductive adhesive as the assembly process is easier without the risk of components dropping off the underside when parts are soldered on the top. When using electrically conductive adhesive for an entire electrical assembly, it negates the requirement to undergo a solder re-flow process.

Nature of the materials being bonded and level of adhesion required. For example, joint design, the strength required, any differential thermal expansion and contraction, thermal conductivity, glass transition temperature, and flexibility requirements. ECAs can be used in applications which involve high reliability or temperature sensitive components. With an array of curing temperatures and application methods (jetting, screen printing, dispensing) electrically conductive adhesives offer flexibility to a production line and a wider scope for electronic assembly.An unfilled epoxy with independent heat-curing (50 minutes at 80°C) and light-curing (4 seconds at 150 mW/cm2) mechanisms.

is an electrical adhesive that is highly filled to maximize electrical conductivity. For a more economical version, use 8331 or 8331D. For a longer working life, use 8330D or 8330S. Conductive epoxy, also known as electrically conductive adhesive or conductive glue, is a material that consists of an epoxy resin mixed with a conductive filler. These resins require “curing” or a “setting time”, before the connection is secure. This means that the glue hardens out. The conductive material contained in the epoxy is often silver (Ag) or a form of carbon (graphite). An example is Ablebond’s 84-1LMISR4. Why should we use a conductive epoxy? One component epoxy adhesives are normally heat cured so take care to choose a cure schedule that won’t compromise sensitive electronic components. Snap-cure frozen epoxies are also popular for the electronics industry; these products require freezer storage and cure once they reach room temperature. These can be expensive to transport and store. A silver filled one-part epoxy can achieve conductivity as high as a similarly filled two-part epoxy. Due to its versatile nature, copper foil tape can be used in a wide range of applications and environments. It is used by professionals and hobbyists alike, across a spectrum of uses including electro-magnetic shielding, slug repellent, and DIY crafting. This is the ability of the adhesive to store a charge (electric flux). This is affected by the temperature, and also the glass transition temperature (Tg) of the adhesive as insulating properties change above and below the Tg. So, the higher the Tg, the better the retention of dielectric properties at elevated temperatures. Typical values for insulating epoxy glues are around 4 to 6 at around 1 mHz. Volume ResistivityTo use, simply peel the tape and place it on the edge of the first piece of glass. Press it firmly down around the edge of the shape, taking extra care if the glass is sharp or jagged. Ensure that each new section of tape you apply overlaps with the last to avoid any gaps. Copper Tape for Walls Production line considerations. Firstly, how fast is the throughput? Secondly, is the process fully automated or manual? How will you dispense the adhesive? Isotropic conductive adhesives are electrically conductive in all directions and are therefore ideal for die attach, chip bonding, attaching SMDs, etc. Anisotropic conductive adhesives only conduct electricity in one direction, so these are often used for very sensitive electronic components such as LEDs, LCDs, and RFIDs.

It is a conductive material but is available in two common types, known as conductive and non-conductive. Conductive tape can conduct electricity on both the top and bottom of the tape, whereas non-conductive copper tape is only conductive on the one side. This makes each of the different types best suited to varying applications. There are a number of reasons electrically conductive adhesives might be a more suitable alternative to other methods of bonding and adhesion. These high-performance adhesives are often used as an alternative to solder in applications where the components being bonded are temperature sensitive. Given the cure temperature of an ECA is far below that of relfow temperatures, this opens the door to sensitive componentry, less energy usage, and flexibility of processing Soldering is a relatively straightforward process, but it is important to solder safely and ensure the correct equipment and soldering iron tip is used to create a secure join. Safety is essential so always make sure you are fully prepared for the task before using soldering equipment. Copper Tape for Shielding An unfilled epoxy ideal for fast-curing applications: 2 minutes at 150C. Longer than usual pot life of 5 days.For over two decades, 8330 has been our flagship product. Now, after much research and development activity, we are excited to announce 8330 will be replaced by an improved version, 8330D. 8330D offers improved productivity, curing at room temperature in only 5 hours instead of the 24, while offering twice the working time, 20 minutes instead of the old 10 minutes. As well, 8330D offers improved conductivity and flowability. It also provides higher safety, being free of SVHC’s and no Proposition 65 listed ingredients I need to do a small repair on a laptop circuit board & dont want to go near it with a solder iron as its in a tight spot near chips & many tiny connections. Industry-leading LOCTITE ® ABLESTIK die attach adhesives are highly conductive, metal-filled adhesives with excellent electrical conductivity, dispensability, and high-reliability performance designed to meet the requirements of today's challenging, high-density die architectures. This measures the electrical conductivity or electrical resistance of materials, taking into account sample dimensions (hence the “volume” part). Test standards associated with this are the old MIL STD-883, ASTM D2739, and ASTM D257-99, a test method for measuring DC resistance or conductance of insulating materials. Units of measurement associated with Volume resistivity are typically Ohm∙cm. Accordingly, the lower the figure, the more electrically conductive the adhesive is. What do isotropic and anisotropic mean in relation to electrically conductive adhesives?

I have had mixed results in my experiments with powdered metals. While they often produce the lowest resistance per inch, they tend to make the resulting mix quite brittle. They also considerably increase the price of the glue mix. If you would like to see a list of the metals I have tried and the results along with the latest update on Conductive Glue Experiments, you can see them at: http://www.inklesspress.com/conductive_glue.htm About: I believe that the purpose of life is to learn how to do our best and not give in to the weaker way. Panacol provides an extensive Elecolit ® product portfolio of one- and two-part conductive adhesives for: Electrically conductive adhesives can be used to paint the inner surface of plastic boxes containing electronic devices. This makes a Faraday cage saving the internal components from electromagnetic radiation. An unfilled epoxy ideal for fast-curing applications: 2 minutes at 150C. Ideal for Smart Card applications.This is the maximum voltage the adhesive can withstand before it is destroyed. In fact, it is also known as “breakdown voltage” for reasons which explain themselves. We want to connect a Strip of 4 flat cable to a USB [B] type male connector at 90 * angle to protect the Vintage Electronic Board, or any others. Electrically conductive epoxies come as either one or two-part adhesives. One-part epoxies are normally heat cured. This means that care must be taken to choose a cure schedule that won’t compromise sensitive electronic components. Two-part epoxies comprise of a resin and a hardener. When filled with silver, both one and two-part epoxies are effective substitutes for solder.
