Conductive Wire Glue/Paint - NO Soldering Iron

Product Information

A high viscosity unfilled epoxy with independent heat-curing (60 minutes at 80°C) and light-curing (5 - 10 seconds at 60 mW/cm2) mechanisms. 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 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 An unfilled epoxy ideal for fast-curing applications: 2 minutes at 150C. Longer than usual pot life of 5 days. The strain gauge or a glued resistor can also be used as a temperature sensor. If it is taken from the shade into the full sun, the resistance increases. So, it could be used to measure the difference between room temperature and overheating conditions.

Electrically conductive adhesives are primarily used for electronics assembly. These adhesives are ideal for electrical interconnect but also for thermal and structural bonding applications, offering improved reliability in electronic systems. 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?The liquid itself will contain different conductive adhesives such as iron, copper, gold, etc, and will disperse these equally in the form of a polymer resin. The resin can be applied to several different areas of use and will help make repairs for instance. Product Types 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 Elecolit ® conductive adhesives are relatively simple to apply. With the appropriate selection of filler type, they can be dispensed through automated valves, high speed “Jet” dispensing systems, and screen printing.

Recently our quality engineers at EPR rejected a PCB after its standard soldering process. The reason: a bad soldered component (TDK Capacitor 150pF CGA3E2C0G1H151J080AD). After analysis it was clear that this particular part should be used for conductive epoxy glue instead of the standard soldering process, because it had AgPd plating on its terminals. What is 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. 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.

To glue two wires together, if you can, you should first twist or crimp them together and then coat them all the way around with conductive glue. If you merely lay them side by side without touching and then glue them, the resistance of the glue joint will be in 7-9 ohm range. See fig-A if you are using conductive thread (resistance is about 2 ohms per inch) for wires, you can tie an overhand knot to the wire you are connecting to and then coat all around it with the glue. A fast-curing epoxy (3 minutes at 150°C) with excellent compliance for larger die applications. Can be light-fixed in seconds for high-placement accuracy. Very long pot life of 7 days. 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. As with many things in life, there are certain trade-offs. In the case of electrically conductive adhesive they are: 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.Paper circuits are low-voltage electrical circuits that can easily be created using a selection of common materials. They are often used in DIY or domestic settings, often to teach children about circuits and electrical conductivity. 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. Silver-filled polyurethane adhesives are starting to appear on the market. They are two-part adhesives, so they either require mixing or they are supplied pre-mixed and frozen like the snap-cure epoxies. They offer high peel strength and flexibility. As they are silver filled, high levels of conductivity can be achieved (around 0.0001 Ohms∙cm to 0.0004 Ohms∙cm). Electrically conductive adhesives are used in SEM to fix and ground the sample to avoid electrostatic charging of the surface. Conductive Adhesives are used as an alternative to soldering in some cases and typically found in applications such as;

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.A high viscosity unfilled epoxy with independent heat-curing (60 minutes at 80°C) and light-curing (2 - 6 seconds at 60 mW/cm2) mechanisms. Very high Tg of 185°C. 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. If just a small current is needed, a temperature-sensitive electronic element can be electrically connected to a circuit using an electrically conductive adhesive instead of soldering. suppliers of an extensive range of EMI shielding materials and components that include conductive adhesives,
