Considerations for electrically conductive low temperature epoxy silver adhesive glue for circuit boards chip packaging and bonding
Different things have to be considered when picking electrically conductive adhesive for circuit boards. We already know that circuit boards are heat sensitive, and that is why we need to find a suitable adhesive to eliminate the need for using a soldering iron. At DeepMaterial, we work hard to formulate some of the best adhesives to meet the different market demands. At the end of the day, the best electrically conductive adhesive for circuit boards can help deal with different processes.
• When making the best choice, you will have to consider the materials that have to be bonded and the required adhesion level. You need to consider the strength needed, joint design, contraction, and thermal expansion. When picking the best electrically conductive adhesive for circuit boards, flexibility requirements, transition temperature, and thermal conductivity are also considered.
• Some of the environmental conditions have to be considered, including humidity, exposure to chemicals, and temperature. This is especially important if the component has to be left outdoors. It is wise to have a component adhesive that is not altered by heat. A waterproof adhesive can also be very helpful in such a situation.
• You need to determine whether the electrically conductive adhesive for circuit boards has been tested. Such an adhesive needs to be tested thoroughly. Accelerated imaging tests and drop tests are some of the most important. They test the strength and durability of the adhesive.
• Safety considerations, shelf life, storage, smell, and color are important considerations. Reading the safety precautions that we layout on our products should be enough to keep you safe as you use them. The color, especially after curing, can be a great way of determining whether the adhesive meets the requirement and will match the project. Some of the adhesives are very adaptive to projects. We have a wide variety of choices to work with.
• Another very important consideration is the cost. Our prices are very fair and the quality great. However, when considering the cost of electrically conductive adhesives for circuit boards, don't compromise the quality. You should find something that is very functional and effective within your budget. Remember, customizing the adhesives to meet your specific demands is the option.
Chemistries
To come up with the best electrically conductive adhesive for circuit boards involves various chemistries. You can pick:
• Silicone adhesives: these may be graphite-filled. They are viscous and are suited for some large applications like bonding large areas or gasketing
• 2 component epoxy adhesives contain a hardener and resin and come in different viscosities. When conductive metal is heavily used, the viscosity can be high.
• Single component epoxy: they are heat cured, so you will have to be careful choosing these for circuit boards
• Polyurethane adhesives silver-filled: these are also available today. Basically, they are 2-part adhesives and may require mixing. However, we can also supply them in an ore mixed form. They may be frozen and offer great flexibility.
The product has excellent weather resistance and has good adaptability to natural environment. Excellent electrical insulation performance, can avoid the reaction between components and lines, special water repellent, can prevent components from being affected by moisture and humidity, good heat dissipation ability, can reduce the temperature of electronic components working, and prolong the service life.
This product is a one component heat curing epoxy with good adhesion to a wide range of materials. A classic underfill adhesive with ultra-low viscosity suitable for most underfill applications. The reusable epoxy primer is designed for CSP and BGA applications.
