Electrically conductive adhesives are used in SEM to fix and ground the sample to avoid electrostatic charging of the surface. You can create a line stencil by cutting a 1/8" or wider slot in a piece of cardboard and painting in the slot. To create resistors you should first test your mix between two wires taped an inch apart. Let it dry overnight before you measure the resistance. Even when slightly wet, the resistance will be higher. To create a resistor I use a mix of 1/2 graphite to 1 liquid glue or of 1 to 1. To increase the resistance add less graphite to the mix or make the line less wide or thinner or longer. 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. There are many kinds of conductive epoxies, glues, and rubbers available. Unfortunately, they are for the most part quite expensive.

Two-component epoxy adhesives comprise resin and hardener and are available in a range of viscosities. However, if heavily filled with conductive metal, viscosity can become quite high. If filled with silver, volume resistivity can be as low as 0.0001 Ohms∙cm. 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. Geometric designs are common, but there are certainly no restrictions on your creativity! Alternatives include the use of washi tape or simply using masking tape to enable precise, accurate lines between different colours or shades of paint on a wall. Copper Tape for CraftsStrong bonds and gapless performance to enhance uniformity across seals and negate the need for mechanical fasteners. 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. LOCTITE ® Bergquist ® thermally conductive adhesives offer a range of benefits. By combining heat dissipation with adhesive bonding, you can save space in components and make fasteners redundant. Benefits include:

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. In the US, dielectric strength is often specified as volts per mil (a thousandth of an inch). Whereas elsewhere, it is mainly V/cm (or mm or m)Also, the viscosity and rheology of the adhesive. Whether it needs to flow well or stand as a proud drop (with high “wet” strength). 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).

also includes an advanced 'form in place' gasket process that enables us to efficiently apply conductive gaskets and environmental seals, directly onto enclosures, mouldings, covers etcHenkel thermally conductive glue products combine fantastic bonding abilities with unrivaled thermal management capabilities. This allows for necessary heat dissipation in heat-generating components, while also reducing the need for clips and screws. This makes conductive adhesives the perfect option when assembling smaller, lighter electronics.
