Application of Electronic Adhesive

Adhesive, also called Paste. It is the material in liquid state, connect two or more materials together, after a certain way of curing, has enough bonding strength of the substance.

Why we use adhesive? It has many advantages:

(1) If adhesive wholly surfaces coating, it can withstand greater load. So, for some bonding area relatively small, adhesive is more appropriate because the traditional rivets screw welding process is difficult to realize.

2) It can bond different kinds of materials, a wide range of applications.

3) Lightweight structure, beautiful appearance.

4) Adhesive plays a role in sealing, good weather resistance, aging resistance, solvent resistance, etc.

(5) The process operation is relatively simple, the cost is not very high.

(6) Adhesive is filled with a variety of functional materials to create many composite functional products, such as thermal conductivity and electrical conductivity.

In electronic products, adhesive has a large number of uses, especially miniature products, such as camera modules, fingerprint modules, headphones, speakers, and narrow bezel window adhesive, liquid crystal sealing, thermal conductive gel.

For different applications, there are different types of glue, according to the composition of the classification, generally the following types of products are used in electronic products, acrylic, epoxy, polyurethane, silicone and fast drying category.

Also there are anaerobic adhesive, mainly used in screw fixing, the need for ultra-high temperature resistance, if the use of inorganic materials, the life of the common cement is also a kind of inorganic material glue.

Adhesive in the electronics industry is generally used in syringes, filling, barrels. The following picture is a typical set of packaging.

If the point of two-component glue, you need this mixing tube, through the spiral static mixer, the glue will be mixed.

In this line, Henkel is the industry leader, especially light-curing and quick-drying adhesive technology strength is relatively strong, DOW, Wacker in silicone is relatively strong. In addition, DOW in the epoxy and urethane is also good, 3M, Sika, Dymax, DELO, H.Bfuller, Huntsman, Bostik, DEVCON, CEMEDINE are famous enterprises. We are long-term cooperative relations with them.
