Introduction of computer motherboard:
Computer motherboard, also known as motherboard, system board, logic board, motherboard, backplane, etc.
A typical computer motherboard can provide a series of joints for the processor, graphics card, sound card, hard disk, memory, external devices and other devices to join. They are usually plugged directly into the relevant slots, or wired. The most important component on the motherboard is the Chipset. The chipset usually consists of a north bridge and a south bridge. The north bridge is mainly responsible for controlling the communication between CPU, memory and graphics card, while the south bridge integrates many circuits and control modules such as boot, reset, CMOS circuit, USB, IDE, SATA, PCI, etc , they are the core of the entire motherboard.
With the trend of increasing the frequency and speed of computer motherboard devices, the heating power has become the main technical bottleneck. How to obtain the optimized transmission performance through the design and introduction of heat-conducting and heat-dissipating components, and meet the requirements of high reliability, cost, etc. Different needs have become the key to heat dissipation engineering.
Glue requirements for computer motherboards:
- Temperature resistance -40~130℃;
- Strong adhesion to components;
- Excellent heat dissipation for heating components;
- Environmental protection, non-toxic, with conventional ROHS testing certification and qualification;
- Moisture-proof, anti-static, dust-proof, mildew-proof, salt spray resistance, etc. for circuit boards;
Glue scheme for computer motherboard:
|Glue dots for computer motherboards||Glue function category||Features of glue application|
|Component heat dissipation||Thermally conductive silicone grease, thermally conductive silicone sheet||It has excellent thermal conductivity, heat dissipation, electrical, insulation, moisture-proof, shock-proof, aging resistance, and can work for a long time in the temperature range of -40℃~200℃|
|Components fixed||adhesive sealant||Strong bonding ability, fast curing speed, resistance to alternating heat and cold, good electrical insulation, excellent acid and alkali resistance, aging resistance, UV resistance, no solvent, no pollution, no corrosion, easy to use|
|circuit board||Three anti-paint||It has excellent insulation, moisture-proof, anti-leakage, shock-proof, dust-proof, anti-corrosion, anti-aging, corona resistance and other properties|
Due to the difference in the structure, process and application environment of the computer motherboard, the glue application may be different. If you need other glue application, please contact Cohetion
