What is modern electronic printing? What's the difference with traditional printing? thank you

Electronic printing is a very broad concept. In a narrow sense, electronic printing is an electronic circuit manufacturing technology using printing technology, including PCB (printed circuit board), organic light emitting diode (OLED), LCD, LED, TFTC and the latest RFID. Electronic printing in a broad sense also includes the printing of electronic products, such as the printing of computer keyboards, the printing of mobile phone cases and so on. It is precisely because of the particularity of electronic products that the equipment and ink pigments used in electronic printing have special requirements.

Worldwide, the printing industry is in a downturn. Some people may ask: "Will the printing technology that has been developed for centuries quit the historical stage?" Maybe it's not that simple denial. An exciting answer is "electronic printing". In the next 20 years, the printing electronic market will accelerate to become a market worth $300 billion.

Printed circuit boards are divided into hard laminates (phenolic laminates, glass cloth epoxy laminates, etc. ), combustible board (polyester film, polyimide film, etc. ) and inorganic insulation board (ceramics, etc.). ); From the composition of layers, there are single board, double board and multi-layer board; There are three manufacturing methods: etching copper foil (reduction method), copper plating (additive process) and conductive printing.

Multi-layer printed circuit boards are formed by overlapping and pressing extremely thin single-layer printed circuit boards. Multilayer printed circuits are interconnected through metallized holes, and 4-layer boards and 6-layer boards are widely used, which has the advantages of further reducing the volume, shielding each other between layers and improving the working stability of the circuit.
