Things to consider when picking high refractive index optical adhesives glue for precision electronic component assembly

Best index optical Adhesive Glue Manufacturer

There are many things that have to be considered when picking the best high index optical adhesives for electronic assembly. Choosing an high index optical adhesive is not that easy, but you can find the best available in the market and be on your way to greatness with the right idea in mind.

Choosing the right high index optical adhesive becomes even more complicated when you have a specific application in mind. There are so many variables to be considered and different chemistries available. Some parameters can help you as an individual narrow your choices better. Picking an ideal high index optical adhesive reduces products that have to be evaluated and boosts the chances of success.

To be on the safe side, there are some parameters that one should have in mind, and at the end of the day, you should have the best high index optical adhesive for electronic assembly. They include:

Substrates

This is the first thing you have to know. You need to have in mind all the materials that are being bonded. Some high index optical adhesives are preferred for certain materials. There are high index optical adhesives for electronic assembly that ought to be used on glass or ceramic. When we say plastic and metal, these are generic terms, and many materials are in between. Knowing the substrate helps determine the best high index optical adhesive correctly. To illustrate, think of ABS and PTFE. These two are plastics, but they have to be handled differently, ABS is bonded using alcohol cleaning, while PTFE needs acid to etch if a bond is achieved.

Configuration

When picking high index optical adhesives for electronic assembly, configuration needs to be considered. It is important to think about part dimensions and how they are supposed to be fitted. This helps in the selection process. Some high index optical adhesives are best for thicker and larger parts, while others are suitable for thinner ones.

Viscosity

Products with low viscosity or thin products are ideal for applications that need working or for thin bonds. For vertical applications, thixotropic materials are the best.

Working life

You need to consider the work-life desired. The working life refers to the duration it takes the material to gel. If the thermal cure materials have a long working life, the cure time is also longer when the room temperature is used. UV cured materials usually get cured fast, and working life is not applicable.

UV cure VS thermal cure

UV cure high index optical adhesives are easy to cure and are usually just a single part. To be cured, they need UV light exposure, meaning that one substrate has to allow UV light transmission. On the other hand, thermal cure materials need to be cured with heat or room temperature. When curing thermal high index optical adhesives, high temperatures are required. This can cause harm to the different components. When the properties are higher, the cure is faster.

Part cleanliness:

When high index optical adhesives are about to be used, the substrates must be well prepared. This could be a simple clean or being able to handle complex operations like plasma treatment, chemical etches, or abrasion. All these have to be considered when an high index optical adhesive is being selected.

Performance

When picking an high index optical adhesive, think of how you want to perform. This helps in a big way to make a selection.
