Thermally conductive materials to upgrade the waves to explain the VROCUL thermal grease

Based on the excellent heat dissipation performance of liquid metal, VRYCUL has developed two liquid metal thermal paste products, TG-I and TG-II. Once entering the domestic market, it has attracted wide attention from the industry and is of high quality in China. Liquid metal heat sinks set a new benchmark. Experts admit that compared with traditional thermal conductive materials such as water-cooled working fluid and thermal grease , liquid metal thermal grease has stable physicochemical properties, is non-toxic and harmless, and is not volatile. The working environment temperature can be as high as 500 degrees, and it has a wide range of heat dissipation in high heat flux. Applications.

Leading industry's ultra-high thermal conductivity
It is understood that as a company that has long focused on thermal interface materials, the UK's Weiku and Warwick University have worked closely together to launch a variety of liquid metal heat sink products with the joint research and development platform and advanced laboratories of Warwick University and IBM and Jaguar. TG-I and TG-II are the two pure metal thermal paste products brought by Weiku's first entry into China.
The thermal conductivity of TG-I and TG-II is much higher than that of traditional silicone oil-based thermal conductive materials, and it does not contain volatile substances. It has high reliability and good thixotropic properties, which can ensure long-term safe and stable operation of precision heat dissipation system. The thermal conductivity of TG-I and TG-II is as high as 25W/mk and 12W/mk, respectively, which is 5-10 times that of conventional heat conductive materials commonly available on the market. In addition, Weiku has maintained long-term cooperation with well-known industrial design companies, making TG-I and TG-II the most advanced thermal conductive materials in the industry, and is recognized by high-tech product manufacturers including aerospace, laser and so on.

High stability to ensure system safety
The two thermal pastes of TG-I and TG-II are gallium-based alloys with a gallium content of 30%-50%. They are in the form of bright silver and odorless paste solids at room temperature, and have certain corrosive properties to metallic aluminum. Between the ultra-low melting point and high boiling point of gallium, the temperature of the two products reaches an ultra-wide range of -40 degrees to 500 degrees, and the volatilization rate is less than 0.001%, so the chemical stability is super strong and the reliability is high, which can guarantee high The precision heat dissipation system runs safely and stably for a long time, and does not emit toxic substances harmful to the human body.

Segment products to meet different application needs
As two different products, TG-I differs from TG-II in its thermal conductivity and viscosity. The TG-I viscosity is relatively low, reaching 4200 mPa.s, and the relative viscosity of TG-II is higher, reaching 8200 mPa.s. Between the two products, the thermal conductivity and viscosity, TG-I and TG-II are also suitable for different industries and devices. TG-I has a high thermal conductivity and is widely used in high-precision fields such as scientific research, national defense, and high-precision electronics. TG-II has a relatively low thermal conductivity, but has a higher viscosity and is easier to apply. It can be used in laser, military, IGBT, etc. In the industry.
With the continuous development of technology and the increasing integration of electronic devices, the heat flux density of consumer products such as LEDs and CPUs that are commonly contacted by ordinary people is also rising. The demand for high-performance heat sinks in various industries is also growing. . The liquid metal thermal paste introduced by Vico opens up a highly promising market. It is reported that after entering China, Weiku will bring high-quality products to Chinese consumers with EU standards, and fully promote the wave of China's thermal material upgrade.

Peel Mask PCB 

Peel able masks are used in order to protect selected solder holes against plugging during mass soldering or to protect carbon elements and gold plated contacts during mass soldering.  Peel able masks are screen printed.


• The peelable mask must adhere sufficiently well to the PCB so that it does not peel off when handled correctly.
• It must be able to endure a two to three time soldering process without peeling off, but must remain detachable.
•After soldering of the PCB, the peelable mask must be able to be detached – preferably in one piece. In case of metallized holes, no mask 
   residue must be left in the drill holes or on the surface of the PCB. In the case of non-metallized drill holes, however a certain amount of residue 
   can remain.
• The peelable mask must be able to resist conventional solvents such as chlorinated and fluorinated hydrocarbons, isopropanol, conventional 
   fluxes and similar.
• Particular requirements: The roughness U of the edge of the mask can be 0,5 mm from the tip to the base (left figure
