Tablet PC Introduction:

Tablets are also called portable computers.
A tablet is a small, portable personal computer with a touch screen as the basic input device. It has a touch screen (also known as tablet technology) that allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse.

Tablet PC Principle:

The tablet computer is composed of audio signal processing circuit, microprocessor circuit, image processing circuit, touch control circuit, DDR memory circuit, power supply and management circuit, WLAN circuit, Bluetooth circuit, etc.


Tablet PC Composition:

Tablet PC consists of external front bezel, touch screen, display screen, internal motherboard, CPU, heat sink, memory, hard disk, graphics card, sound card, touch module, wide voltage module, I/O interface, wire, back plate, etc.

With the popularity of ipad all over the world, MID products with ultra-thin, touch screen and intelligent system have become the latest consumer favorites; in the design and manufacture of tablet computers, the combination of alloy and engineering plastics for the shell has become a new trend. In the process of production and assembly, the threads and buckles of the optical sensor are very suitable for the realization of ultra-thin, ultra-light, and three-dimensional beauty. In order to realize the gap-free and flat appearance of the tablet, more and more adhesives are used in the assembly process. To bond and fit components.

Glue requirements for tablet PCs:

  1. The initial bonding time is short;
  2. High bonding strength to the chassis frame;
  3. Excellent heat dissipation for CPU and other heating components;
  4. Environmental protection, with routine testing certification and qualifications;
  5. Moisture-proof, anti-static, dust-proof, mildew-proof, salt spray resistance, etc. for circuit boards.

Glue scheme for tablet PC:
