On January 7, 2013, ITU announced at the Consumer Electronics Show that the first batch of devices with a transmission rate of 10GB/s had come out. The USB interface of this kind of products adopts the standard of USB 3.1, which can plug in and out, that is, USB type-c interface. To this day, the type-C interface has long been integrated into our daily digital field. Why can it be so quickly popularized? Nowadays, USB type-c has four major advantages over interfaces such as micro, type-b, and even Lightning:

1. The type-c interface supports the USB 3.1 standard, resulting in faster data transfer speed. In theory, the transmission speed of USB 3.1 Gen2 type-c can reach 10Gbps (1.25GB/s).

The size of the type-c interface is 8.3mm × 2.5mm, its size is similar to micro USB and Lightning, and its portability is excellent. The type-C front and back insertion are the same, so there is no need to worry about interface inversion. Blind insertion is more convenient to use.

The standard cable of USB type-c can pass 3A current, support up to 100W power transmission, and can provide bidirectional power supply, enabling the increasingly popular super fast charging technology.

4. The USB type-c also has strong scalability, which can expand multiple audio and video interfaces and support 4K resolution. The type-c interface has strong compatibility, making it a standardized interface that can connect all electronic devices such as PCs, game consoles, smartphones, storage devices, and expansion docks, and achieve unified data transmission and power supply, greatly simplifying various types of data cables on the desktop. With the rise of smart homes, there is an increasing number of smart home terminals, and it is also an inevitable trend for the charging and protocol interfaces of each terminal to be unified.

With the increasing popularity of type-c interface in digital products, the product process standards are becoming more and more perfect, the production requirements of components are becoming higher and higher, and the type-c chipset is also becoming more and more integrated and intelligent. Therefore, the problems of waterproof, protection, fixation, sealing, and anti-aging are also closely related to our daily use, and the solutions for type-c adhesive are also coming, At present, type-c interface adhesives are roughly divided into two categories: epoxy resin and UV adhesive.

The following is a brief analysis of the advantages of the two, for your reference only when choosing glue:

The main advantages of type-c epoxy resin adhesive are: high strength sealing and fixation, resistance to reflow soldering high temperature, rapid curing at high temperature, no cracking during high magnification microscope detection, IP68 grade waterproofing, aging resistance to meet boiling requirements, simple and convenient operation, Junmao can also adjust viscosity, hardness, curing conditions, molding effect, and so on.

The main advantages of type-c interface UV adhesive are: ultra fast UV curing, sealed and fixed waterproof, can protect chip solder joints, can dry in 5 seconds, suitable for large-scale rapid production requirements, lower average cost, Junmao can adjust viscosity, color, hardness, curing rate, and so on. Of course, its overall aging resistance is slightly worse than the former.

In addition, type-c epoxy resin adhesive and UV adhesive can also be widely used in precision electronic components, connector terminals, plugs and sockets, electronic wires, and so on.
