Two-component Adhesive Cartridge: A Key Partner in The Application of Electronic Glue

In the rapid development of electronic technology, all kinds of electronic products continue to introduce new, increasingly powerful and tend to miniaturize, precision. Behind this, the electronic adhesive plays a vital role, and the two-component adhesive cartridge is the electronic adhesive to accurate and efficient application of the right hand.

Electronic adhesive: electronic products, “solid guardian”

Electronic adhesive in the field of electronics is widely used, is to ensure the stability of electronic product performance and structural safety of important materials. From the tiny chip package, to the circuit board components fixed, line protection, and then to the display of the lamination, etc., are inseparable from the electronic adhesive. For example, in the connection between the chip and the substrate, the electronic adhesive to ensure that the chip is stable, and at the same time have a good electrical insulation and thermal conductivity to ensure that the chip is efficient and free from external interference; in the circuit board, the electronic adhesive is used to fix the capacitance, resistance and other components, to prevent them from vibration or temperature changes in the environment under the loosening of the circuit, affecting the normal operation of the circuit; for the display, the electronic adhesive needs to achieve a reliable adhesion to ensure that the display effect is clear and stable. Display effect is clear and stable.

Two-component adhesive cartridge: the “perfect partner” of electronic adhesive

Electronic adhesive usually consists of two different components, only in the use of their full mixing according to the exact ratio, in order to show the best performance. This requires the special tool of a two-component adhesive cartridge.

Unique design

A two-component adhesive cartridge typically consists of two separate tubes that store the two components of an electronic adhesive. The two tubes are connected at the front of the cartridge by a special mixing device. This design cleverly solves the problem that the two components of the electronic adhesive cannot be mixed in advance during storage and transportation, ensuring the stability and activity of the glue. For example, in common epoxy resin-based electronic adhesives, one component is the resin and the other is the curing agent. In a two-component hose, they are stored separately and only extruded and mixed when they are needed for use.

Precise Mixing and Delivery

When it is time to use the electronic adhesive, the two tubes of the two-component cartridge are extruded simultaneously by means of a matching glue gun or extrusion device. The two components are extruded from their respective tubes in a preset ratio into a mixing unit. Inside the mixing unit, there is usually a series of special mixing elements, such as spiral blades or interlocking channels. These elements continuously split, cross and fuse the two components so that they are homogeneously mixed in a short period of time. The mixed electronic adhesive is then transported through the outlet at the front of the cartridge to the precise area to be glued. For example, in precision microelectronics assembly, the two-component hose can precisely control the amount of adhesive and the mixing ratio to ensure that each tiny solder joint or component gets the right amount of evenly mixed adhesive, which greatly improves the consistency and yield of production.
