Things To Remember When Buying An Electronic Assembly Adhesive Glue And PCB Assembly Materials

DeepMaterial UV curable and epoxies are some of the best for assembly and electronic usage. The adhesives have impressive cure time and viscosity, making them ideal in screen printing for different applications when only a small amount of the adhesive is used. Screen printing allows users to cut on waste in industries like PCB, electronic assembly, and OEM. Deep Material offers different adhesive types, including semiconductor adhesives, die attachments, conformal coatings, surface mount adhesives, and underfill encapsulates.

Best adhesive for electronic assembly 

The assembly of electronics in manufacturing has replaced soldering processes with adhesives. This is because adhesives offer stronger bonds that hold circuit board components together. The adhesives also offer protection to the same components against corrosion, environmental hazards, and vibrations, among many other elements.

Typically, adhesives are applied to electronic assembly for bonding surface-mounted devices, encapsulating, potting, wire tracking, and coating printed circuit boards. The market has many adhesive technologies formulated to meet different application requirements and needs.

Electronic assembly adhesive applications 

Bonding surface-mounted devices – surface-mount devices, SMDs are usually placed on adhesive beads before heat or UV radiation is used to cure them. This process holds the devices in position till they are soldered firmly on the board. Single-component epoxies, acrylics, and urethanes are commonly used for such.

Potting – In potting and encapsulation, the electronic assembly is immersed in an adhesive to offer a shield against physical damage to the components. This application additionally offers insulation to the assembly. The best adhesives for this kind of application are epoxies, acrylics, silicones, and polyurethane.

Conformal coatings – They are thin resin films applied to the electronic assembly by spraying. The coats offer protection to the board components and also provide isolation. Different substances can be used for this application, including epoxies and silicones.

Wire tacking – In wire tacking, an adhesive is used to reinforce any wired connection whereby the wires are bonded to circuit boards to keep them protected from harmful vibrations. Adhesives such as light curable acrylics, epoxies, and cyanoacrylates are most suitable for wire tacking.

Properties of electronic assembly adhesive 

Different types of adhesives can be used for electronic assembly. However, it is important to ensure that the one you choose has the following properties for the best results with the bonding;

Electrical conductivity – Electronically conductive Adhesives are best for electronic assembly. Adding fillers to selected base material can help achieve the conductivity necessary for bonding. Fillers such as carbon, nickel, and silver can be used on epoxy resin base material.

Thermal conductivity – It is a property that helps adhesive transfer heat from sensitive components on electronics and is, therefore, very important. When the heat is transferred, it is dissipated via heat sinks. Acrylics, silicones, and epoxies are formulated to be thermally conductive and hence make good choices for electronic assembly.

UV curable – Adhesives that can cure using ultraviolet rays are very easy to use. They cure fast without any need for heat, which is convenient for many users. Such adhesives will also not require any additives, thus remaining environmentally friendly. Acrylics are best when it comes to this property.

Other properties that you should consider when looking for the best electronic assembly adhesive include the following:

• Flexibility
• Strength
• High dispensing speed
• Fast curing time
