The commonly used ink types for printed circuit boards (PCBs) include:
Carbon Ink: Carbon ink is a common black ink used for printing markings, text, and graphics on PCBs. It has good conductivity and corrosion resistance, and can be used to create conductive pads or connections.
White Ink: White ink is typically used for printing markings, text, and graphics on PCBs. It provides clear visibility and contrast, especially when used on black or other dark-colored substrates.
Silver Ink: Silver ink is a highly conductive ink often used for printing conductive patterns or connections on PCBs. It offers good conductivity, although it can be relatively expensive compared to other inks.
Gold Ink: Gold ink is an ink that contains gold particles and is used for decorative or identification printing on PCBs. It is commonly used in high-end electronic products or applications that require high reliability.
Conductive Ink: Conductive ink is a special type of ink that can form conductive patterns or connections. It can be used in flexible circuit boards, sensors, and other applications that require flexibility and electrical conductivity.
In addition to the mentioned ink types, there are other specialized inks available for specific applications, such as anti-static ink or corrosion-resistant ink. The choice of ink depends on the requirements of the PCB design, the application field, and the preferences of the manufacturer.
