Common problem of thermal conductive silicone parts
Thermal conductive silicone and simple comparison of the thermal conductivity silica gel
1. The coefficient of thermal conductivity, thermal conductivity coefficient of thermal conductivity of silicone grease is higher than the thermal conductive silicone, respectively is 4.0 to 5.5 w/m.k and 1.75 2.75 w/m.k
2. Insulation, thermal conductivity silicone grease for adding the metal powder insulation is poor; Thermal conductive silicone pieces of insulation performance is good, 1 mm thickness of electrical insulation index above 3000 volts.
3. Shape: thermal conductivity silicone grease for condensate paste; Thermal conductive silicone to flake.
4. Use: thermal conductivity silicone grease to daub evenly attentively, easy dirt around devices and cause short circuit; Thermal conductive silicone can be arbitrary cutting, tore to protective film directly stick to use, small tolerance, clean.
5. Thickness: as fill gap thermal conductive materials and thermal conductive silicone restricted; Thermal conductive silicone 0.3 to 16 mm thickness, wide application range.
6. Effects of thermal conductivity, thermal conductivity silicone grease particles is large, aging, thermal effect in general; Thermal conductivity of silicon due to the weak elastic, can greatly increase the heat conduction between the heating element and heat sink area, the processing technology, sophisticated products, stable performance.
7. Price: thermal conductive silicone has been used widely, the price is relatively low; Thermal conductive silicone more application of LED lighting, power supply, routers, switches, thin small precision electronic products such as notebook computer, the price is a little higher.
Thermal conductive silicone piece of common problems of question and answer
Q: generally need to achieve the function of the HEAT dissipation is not equipped with metal HEAT SINK (HEAT SINK)?
A: hard metal heat sink for itself, when in contact with the IC if installation Angle and the contact pressure is uneven, the heat source will not effective conduction into the heat sink, if in the junction of both equipped with soft materials thermal conductivity can effectively overcome the problem of the shortage of the contact surface.
Q: with the timing and application of thermal conductive silicone piece?
Answer: generally speaking, if you have design of electronic products in the space and position have been unable to add fans and metal cooling, can be borrowed by the thermal conductive silicone direct contact IC and shell, directly by heat transfer way to transfer heat to the product of the cold air outside, to achieve the effect of heat dissipation.
Q: equipped with thermal conductive silicone piece what is the benefits of electronic products?
Answer: the products are the most important problem in addition to the function and stability, general electronic parts if it is working in high temperature environment for a long time the parts will be diminishing day by day, the life of a damage, even if in IC mounted on thermal conductivity silica gel to keep its working temperature under low temperature in the product life will be extended effectively.
Q: I rarely see there are sell thermal conductive silicone, like you don't have any reports related data of materials is a new product?
Answer: thermal conductive silicone piece always directly by heat dissipation module factory or electronics assembly plant directly join products in use, less average consumer see, but maybe you can try to see you at hand for optical drive or display card, some of the chip is used to the thermal conductive silicone piece. (e.g., behind the drive motor control chip, according to the above DRAM particles above all with a thermal conductive silicone pieces), now some phones (division (mobile phone) has used thermal conductive silicone shell piece.
Q: the desktop and notebook computer inside there are thermal conductive materials to use?
Answer: general as low noise or no fan of NB is by thermal conductivity copper pipe and the collocation of thermal conductive silicone pieces to achieve the effect of low noise or mute, desktop computer mainly use the location of the thermal conductivity is mostly falls in the south, northbridge, DDR memory use of thermal conductive adhesive tape, the location of the CPU use thermal conductive paste, power supply using thermal conductivity silica gel.
Q: thermal conductive materials will cause the short circuit between the electronic parts?
A: we all series of thermal conductive materials for insulation, resistance to voltage up to thousands of volts, will not cause harm to electronic components.
Q: your thermal conductive materials containing eight metal or harmful substances?
A: we have a full range of material all through the SGS inspection company material inspection, so far all customer specified hazardous substances is far lower than the standard.
Q: your company through the UL safety related with the material of inspection?
A: we all thermal conductive silicone piece of fire rating UL94V - 0 please feel free to use our products.
Q: your company can provide with the material of lamination?
A: our thermal conductive silicone can add back glue, single-sided lamination and double-sided gum
Q: your company's thermal conductive silicone piece what kind of material are there?
A: we have the silicone piece of coefficient of thermal conductivity of thermal conductivity and application of the divided into LG500 high thermal conductivity, LG600 high thermal conductivity, LC250 normal (gray), thermal conductivity silicone grease, thermal conductivity potting glue, double-sided adhesive of thermal conductivity, thermal conductivity of graphite piece, phase change thermal conductive materials and thermal silicone cap sleeve, silicone tube, graphite heat membrane.
Q: your company's thermal conductivity silicone material surface with micro viscous effect?
A: we own micro viscous's thermal conductivity silica gel. Can facilitate customer orientation and heavy industry operations, avoid tearing material itself. Make operators convenient removed from the chassis and heat sink, please put down the use of our products.
Q: what is your company's materials with micro viscous?
Answer: our thermal conductive silicone piece product itself with silicone rubber natural features have faint sticky, easy assembly is easy to use. This comes with viscous stripping more easily than the back glue to prevent tearing.
Q: your company's material hardness after heat will have change?
A: our thermal conductive silicone piece of product itself with the natural properties of silicone rubber, in - 40-200 working environment there will be no obvious change can be very convenient for assembly.
Q: how long have your company's thermal conductive silicon sheet material life?
A: we have silicon sheet product itself with the base material of thermal conductivity of silicone rubber in general that service life of 20 years, thermal conductive silicone piece life mainly is decided by the service life of silicone rubber.
Q: your company's material is heated material precipitation will have?
Answer: all of the thermal conductive silicone products have silicone oil composition, we specially deal with two high temperature and chemical processing and vacuum processing separation problem solved the gas silicone oil.
ULUL is safety testing laboratory accreditation in the United States, is one of the most authoritative certification at present
ROHSROHS is the restrictions on the use of certain hazardous substances in electrical and electronic equipment directive (the restriction of the use of certain hazardous substances in electrical and electronic equipment) of the English abbreviations. At present mainly for electronic electrical products china-germany lead Pb mercury, cadmium Cd, Hg, Cr6, six price +, polybrominated biphenyl PBBs, polybrominated diphenyl ether PBDEs six to limit of harmful substances. Later will be to limit more harmful substances.
GS many people may think GS are "German Safety standards" (German Safety), but in fact, the meaning of GS in the "Safety certification" (GeprUfteSicherheit). GS marks on behalf of the product after could trust of independent institutions, according to the test of "German equipment Safety law", through test and prove their security. GS marks is a standard test qualified, must be in accordance with the production quality system, factory inspection on a regular basis. Law should be inspection on a regular basis (usually a year every two years, depends on the validation rules) manufacturer whether they can maintain the specifications of the product under mass production. In the factory inspection, we will work to evaluate, production environment, as well as related to the production of test and measurement equipment and so on various aspects of the quality system is perfect.
