Cirucit board transparent is a new type of circuit board material whose main components are PET (polyester film) and ITO (Indium Tin Oxide) film. Compared to traditional circuit boards, transparent circuit boards have higher transparency, compressive strength and stability. Transparent circuit boards can be customized into different shapes and structures according to customer requirements and can be used in a wide range of applications.
The special features of transparent circuit boards are their material and production process. The material of transparent circuit boards is generally polyethylene terephthalate (PET) film, which has a transparency of more than 90%. There are three main processes for making transparent circuit boards: rolling, coating and laser printing.
Rolling method is a common process for making circuit board transparent. The process includes raw material preparation, laser cutting, board surface treatment, aluminum foil plating, copper foil plating, plastic overlay copper and final product removal of protective film. The advantages of the rolling method are low cost, simple process and high precision, but the quality and reliability of the produced circuit boards are relatively low.
The coating method is another process for making transparent circuit board. The process requires PET film to be covered on the glass substrate first, then electroplated with copper-clad film, and finally laser cutting, drilling and other processes are used to produce the circuit board. The advantage of the coating method is that the circuit board transparent produced have high reliability and precision, but the cost is relatively high.
The laser printing method is a new transparent circuit board production process. The process requires the use of a laser to print circuit patterns, and then chemical etching and other processes are used to form the transparent circuit board. The advantages of the laser printing method are fast production speed, low cost, and the ability to realize high-precision production, but the process is still in the experimental stage.
Characteristics of transparent circuit boards:
- High transparency: transparency of up to 90% or more, suitable for products that require transparent display.
- Flexibility: good bending and flexibility, can be used in special shaped products, suitable for 3D curved surface display.
- Thin and light: the thickness is generally below 0.1mm, light weight, can reduce the overall weight of the product.
- High temperature resistance: can withstand higher temperatures, suitable for products with higher working temperatures.
- Waterproof and dustproof: waterproof and dustproof technology can be used to meet the requirements of outdoor and extreme environmental use.
- High reliability: advanced manufacturing process, with better electrical properties, conductive properties and mechanical properties, stable and reliable.
