In order to meet the standards of the heatsink industry, Gisen professional digital amplifier has to go through a strict inspection process conducted by precise inspection equipment. Its main performance, namely strength, hardness and wear resistance, is in accordance with national standard GB6063
Advanced inspection measures are used in the production of Gisen professional digital amplifier, such as coordinate measuring machine, gauges, roughness tester, and hardness tester. After being cleaned with compressed air, it has no aluminum shavings
Gisen dsp amplifier is designed and optimized exclusively. Many factors which affect its performance such as materials, air circulation parts, housing finish are all considered during its design. It has no grease or dirt after being treated with degreasing agents
Gisen dsp amplifier is an exclusively designed thermal solution for particular applications. By enlarging its heat radiating area or optimizing the materials in the circulation parts is often conducted to check its heat dissipation performance. Its substrate is protected from corrosion as the product surface can naturally form an oxide film
During the developing of Gisen professional digital amplifier, several important factors are considered such as sink level requirements, component level requirements, system level requirements, and chassis level requirements, to achieve the optimized heat transfer effect. It has a small tolerance being machined by advanced cutting equipment
This product has reliable quality and stable performance. There are no bubbles, undulations, scratches, or dents on its surface
