Thermal conductive ceramic sheet plays an important role in electronic components
According to the statistical data, the reliability of the system decreases by 10% when the temperature of electronic components increases by 2 degrees.The service life of 60 degrees leakage current is only 1/6 of that of 20 degrees leakage current.Temperature is one of the most critical factors affecting the reliability of machine and equipment systems.This requires a disruptive innovation to effectively limit the leakage current of chassis and electronic devices, that is, thermal design solutions.
One, how can we really use the machine shell heat?
The opportunity for flexible silicone rubber thermal insulation materials comes.Flexible thermal conductive ceramic pieces of rubber insulation pad is heat conduction page of the raw materials, sheet material, can according to the size of the hot power electronic devices and arbitrary cut, superior heat transfer of the ability to work, and the characteristics of the insulation layer, its efficacy is add hot filling power electronics device and the heat pipe radiator space inside, is instead of the thermal conductive silicone thermal conductive paste and mica sheet (material) of thermal conductivity of the best commodity dual heat pipe cooling system software.
The heat transfer coefficients of the commodity are 1W/mK and 2W.Resistance voltage breakdown value in 10 kv/mm or higher, in the vast majority have insulation regulation can be used in electronic products. Processing its thickness from 0.5 mm to 10 mm, 1 plus 3 t per 0.5 mm, 0.5 mm 1 mm, 1.5 mm 2 mm to 5 mm, could be up to 10 mm requirement, its thickness is not the same in order to convenient for designers to heater, and the size of the gap between heat pipe cooling device to adopt different alternated goods, more than the best yes add filling effect.If the heat transfer coefficient exceeds 1W, TP150/TP200/TP250/TP300+ h40-t10-s are all flexible thermal conductive ceramic plates, and their heat transfer coefficient is 1.5w /2W/ 2.5w /3W successively.
Flame retardant fire safety features to UL 94 v 0 regulation, and accord with the European Community SGS environmental protection product certification, the operating temperature is usually to 40 ℃ ~ 150 ℃, thus, it is a good thermal conductive materials, and it is very soft, designed as a use of clearance transfer the design manufacture of calorific value, can add filling gaps, in hot position and the position of heat convection heat pipe cooling, improve heat transfer area, also has the shock absorber with insulation sealing effect and so on, satisfy the social machine equipment practical thin design scheme of the regulation, is a process performance and practicability of the new material. And its thickness application field is wide,Very suitable for car, display screen, computer and switch power supply and other electronic products manufacturing industry.
Ii. Electronic application of heat-conducting ceramic plates:
In the daily life of normal work, thermal conductivity ceramic chip has gradually applied in electronic electrical goods control mainboard interface, block of inside and outside of the motor and floor MATS, electronic electrical, mechanical equipment, car, notebook and desktop PC disc machine, DVD and all need to add filling and heat pipe heat dissipation module of raw materials.To use silicone rubber as raw material, coupled with other auxiliary materials such as hydroxides, the production and processing of this heat transfer medium raw material, the key role is designed for use gap transfer heat, together with insulation layer, shock absorbers, seals and other effects.
Iii. Usage of thermal conductive ceramic tablets:
1. Maintain the washing of the finished surface of the thermal conductive ceramic sheet to prevent the fouling of the thermal conductive ceramic sheet, and the worse the self-adhesion and sealing heat transfer of the polluted thermal conductive ceramic sheet will be.
2. When taking thermal conductive ceramic pieces, the thermal conductive ceramic pieces with a large total area should be clamped from the position of management center, while the foam board with a small total area should not be clamped. Due to the uneven support of the thermal conductive ceramic pieces, deformation will be caused, which will harm the actual operation of events, and even destroy the ceramic rolls.
3. Take the sheet with the left hand and tear off at least one side of the release membrane with the left hand.It is not allowed to tear the double-sided original film together, reducing the frequency and total area of immediate contact with the heat-conducting ceramic sheet, and maintaining the self-adhesive and heat transfer property of the heat-conducting ceramic sheet so as to damage it.
4. Tear off one side of the original film and face the house towards the heat pipe radiator.Slow learning to put down thermal conductive ceramic pieces.Care must be taken to prevent bubble formation.
5. If the bubble is caused in the actual operation, the process mentioned above can be repeatedly pulled on the ceramic coil, or the bubble can be gently erased by special tools. The energy is only too large to prevent the thermal conductive ceramic sheet from being harmed.
6. Tear off one side of the original film and put it into the heat pipe radiator. Tear off the last one of the original film with a small amplitude to prevent contusion or pull on the heat-conducting ceramic sheet.
7. After tightening or using the strong adhesive heat-conducting ceramic sheet, release the necessary working pressure on the heat pipe radiator and store it for a period of time to ensure that the heat-conducting ceramic sheet is fixed well.
In general, the actual heat dissipation effect of heat-conducting ceramic pieces is very good, and in the whole process of installation of heat-conducting ceramic pieces, it is suggested that we should be cautious and not be too impatient to achieve, causing harm to bubble and heat-conducting ceramic pieces, resulting in luxury, waste of money and delay of time.
