What kind of glue can I use on a PCB circuit board?

Adhesives have changed the way things are done in a big way. There are adhesives for almost all applications today, and when used correctly, there are many benefits. The tricky part is achieving the ideal bonding that you desire.

When you want to use glue on a circuit board, you must be careful and make the right choice. The kind of glue you can use on a circuit board includes epoxy glue, acrylics, cyanoacrylates, silicones,  and urethane acrylates. There are many applications where the above adhesives can be used, including surface mount gadgets. You would need electrically conductive glue options.

Choosing an adhesive

There are different handling stages that need to be considered when we are picking the ideal adhesive for circuit board applications. These are the cured phase of the solid material, the transitional or curing phase, and the uncured or liquid resin phase. The way the adhesive presents itself after curing is very significant. This greatly enhances the quality.

It is important to consider the application method. It is important to have the right quantity applied to the right spot. Some techniques include screen printing, pin transfer, and syringe application. The most popular option is the syringe application.


  • Ultraviolet curing glues: these are used within the hardware industry. They can meet material necessities as demanded in industries. Light-curing glues are some of the best for PCBs because they cure fast. They are usually acrylic based. They usually have photographic initiators that are cured by radiation.
  • Thermally conductive glues: some issues can affect electronic hardware, including heat. Heat may cause a malfunction, especially when achieving the right working temperature is hard. Thermally conductive adhesives secure diodes, semiconductors, and other gadgets to the right heat sink. This means the heat will not affect the gadget in question. Metallic or nonmetallic powders can be mixed with glue to make them thicker and thermally conductive. The most popular hot glue is created using epoxy, silicone, and acrylics.
  • Electrically conductive PCB adhesive: most glues are nonconductive electrically. However, there are some PCB applications where electrically conductive adhesives are needed. These are isotropic and anisotropic. Anisotropic conduct electricity in every direction, while isotropic ones conduct in one direction only. Even though conductive glues are very valuable, they cannot be used on all materials. They are not a good fit for aluminum or tin. Nonconductive adhesives can be conductive by using fillers as the base material. The most common fillers include silver, nickel, and carbon.

Other glue types include polyimides, silicone resins, and cyanoacrylates.
