Green polyester tape is a green high-temperature tape with a PET film as the substrate and a layer of silicone adhesive applied uniformly on one side of the substrate. Green polyester tape produced by our factory has excellent temperature resistance and acid and alkali resistance. PET polyester film tape is mainly used for the shielding protection of paint spray plating and high temperature protection of other electronic components, also known as static electricity. Spraying tape, high temperature spraying masking tape.

Due to the strong Coulomb repulsive force, direct writing of conductive patterns on an insulating substrate is of great difficulty for NFES. An AC electrical field has been introduced to change the transfer characteristics of the charge along the jet, by which the Coulomb repulsive force can be weakened and the stability of the charged jets can be improved. Nguyen and Byun used a nozzle that was not connected electrically to overcome the electrical breakdown in a conventional NFES system. As shown in Fig. 9.9, an AC voltage is applied to an extraction electrode and the reflection of charged droplets due to patterned geometry on the substrate decreases owing to the patterned geometry on the substrate. Under the AC voltage, positively and negatively charged droplets can be obtained. With the alternation of positive and negative voltage, the jet will be turned to an electrically neutral state, which is helpful for the continuous ejection of droplets even at the peak signal of voltage. Based on the single AC potential setup, dots with sizes ranging from 10 to 30 mm were generated on the substrate. Zheng et al. investigated the effects of process parameters on the microdroplet ejection behaviors under the AC electrical field. The deposition frequency increases and the droplet diameter decreases with increasing AC voltage frequency. In addition, the deposition frequency and droplet diameter increase with increasing duty cycle and solution supply rate. Based on the aforementioned research, Liu et al. printed a bead-on-string structure under an AC electric field. The positive voltage drags out more solution and form beads, while the negative pulse voltage provides the opposite force to stretch the jet into nanofibrous structures between two adjacent beads. The stability of the jet can be enhanced by increasing the voltage frequency. As the voltage frequency increases from 10 to 60 Hz, the diameter of the bead structure decreases from 200 to 110 mm, as presented in Fig. 9.10.

With excellent electrical properties, heat dissipation capability, electromagnetic shielding, high dielectric strength and resistance to bending, aluminum substrates are widely used in many industries such as high-power LED lighting, power supplies, TV backlighting, automotive, computer, air conditioning inverter modules, avionics, telecommunications, medical and audio. When it comes to cell phone cameras which are the most commonly used in our daily life, aluminum PCBs are of great importance. As a metal core PCB (MCPCB), aluminum PCB has many similarities with FR4 PCB in terms of manufacturing process or technology, including thick copper foil etching, aluminum surface etching protection, aluminum board manufacturing and solder resist film printing.
Since the 1970s, aluminum PCBs were first used in power amplification hybrid ICs and have become popular. Due to the development of LED industry in recent years, the application and trend of them are increasingly widespread. Therefore, in order to better utilize them in the product and industry, it is necessary to understand some important characteristics of the PCBs.
Structure of Aluminum PCB
In terms of the structure, it truly shows the structure of aluminum CCL consisting of copper foil, dielectric layer, aluminum base and aluminum base film (which is optional).
(1) Copper foil layer
The aluminum CCL has the same copper foil layer as the ordinary one. The circuit layer requires large current carrying capacity, which is the reason for changing thicker copper circuits from 1 ounce to 10 ounces. The back of the copper foil must be chemically oxidized while the surface should be zinc-plated and brass-plated to improve the peel strength.
(2) Dielectric layer
The dielectric layer consists of a layer of thermally conductive dielectric material with low thermal resistance and a thickness of from 50μm to 200μm, which is the core technology of aluminum CCL. It excels in resistance of heat and aging and can withstand mechanical and thermal stress.
(3) Aluminum base
The aluminum base is actually the aluminum substrate material and is the support component. It requires a high thermal conductivity to be suitable for general mechanical engineering, such as drilling, punching and cutting.
(4) Aluminum base film
The aluminum base film serves to protect the the surface from scratches and etchants. The films can be classified as normal one (below 120°C) and high-temperature-resistant one (250°C). The latter type can meet the requirements of HASL as a surface finishment.
Aluminum PCB performance
(1) Heat dissipation
Compared to normal FR4 PCBs, the aluminum PCBs perform better and more quickly in heat dissipation. Take the FR4 PCB and the aluminum PCB with the same thickness of 1.5mm as an example. FR4 PCBs have a thermal resistance of from 20°C/W to 22°C/W while aluminum PCBs have it of from 1°C/W to 2°C/W, which proves the feature again.
(2) Thermal expansion
The thermal expansion and contraction are common properties of substances but have different coefficients. Because of the excellence in heat dissipation of the aluminum PCBs, the problems on the thermal expansion and contraction on the board surface will be significantly reduced to increase the durability and reliability of the entire equipment and electronic devices. This kind of advantages can be particularly suitable for the thermal expansion and shrinkage problems of surface mount technology (SMT).
(3) Dimensional stability
The aluminum PCBs have significantly stable dimensions. Their dimensions will only change about 2.5% to 3.0% when they are heated from 30 ℃ to 140 ℃ or even 150 ℃.
(4) Other performance
a. Applicability to power device SMT.
b. Effective thermal expansion of circuit design.
c. Helpful to reduce operating temperature, improve product power density and reliability, and extend the shelf life of products.
d. Helpful to reduce the size of the product, hardware and assembly costs.
e. Easy replacement of fragile ceramic substrates with better insulation performance and mechanical durability.

the 200cpsi metallic substrate. Race ones are 100cpsi but the standard on production cars is more like 400-500cpsi with a ceramic substrate. This should also help with noise levels as I have no mid box
