Plastic circuit boards are another type of thermoplastic engineering plastic circuit board compared to the traditional thermosetting epoxy resin fiberglass that is widely used in the electronics industry.

　　Traditional printed circuit boards are made by die-casting thermosetting resin and glass fiber into a substrate, and then bonding conductive copper foil onto the substrate. It is called printed circuit copper clad plate. Copper clad boards are made into printed circuit boards through processes such as exposure and etching. This process has armed the electronics industry to this day. However, the process of removing copper foil involves environmental issues, and approval of circuit board licenses is strictly prohibited in many regions. Printed circuit boards are a planar structure, although flexible circuit boards can be formed on curved surfaces as a branch, they are not rigid curved three-dimensional structures. Some emerging applications, such as robots, 3D lighting fixtures, and precision instruments, require three-dimensional circuit boards. Green and environmentally friendly manufacturing technology is also needed. The Magnetoelectric Materials and Devices (Shenzhen) Engineering Center and BASF, Germany, etc. invented laser plastic. They used traditional injection molding technology to make plastic parts of arbitrary shape and used laser technology to selectively deposit metal, realizing three-dimensional assembly of circuits.
