Application of 3D printing technology in PCB prototype board

3D printing technology is getting more and more attention in PCB prototyping. Recently, foreign scientists have just developed a new method of injecting water into silicone oil and then completing another 3D printed sculpture pipeline of liquid in one liquid. The ability to fabricate 3D structures entirely of liquid through the 3D printing technology PCB paves the way for the manufacture of electronic circuit board equipment that requires flexible telescopic devices.

According to scientists' predictions, the pipelines and flowing molecules are chemically adjusted to find a new way to separate molecules or accurately transport nanoscale building materials to the bottom layer. Researchers have printed "waterlines" between 10 microns and 1 mm in diameter and have lengths of up to a few meters on different spirals and branches.

In the test, shortly after the water was injected into the oil, dozens of ligands in the oil adhered to individual nanoparticles in the water to form a nano-scale super soap. These super soaps are squeezed together like glass, making the interface between oil and water very stable and locking the liquid structure. “This stability means that we can stretch the water into a tube and it is still a tube. Or we can shape the water into an ellipsoid, which is still an ellipsoid.

They then let the printer insert the needle into the oil base and inject water into the predetermined pattern. “We can squeeze liquid out of the needle and place it anywhere we want in three dimensions,” says postdoctoral researcher Joe Forth. “We can also flatten the material with external force, so that we can instantly break the stability of the super soap and change the shape of the water line. This structure has a high load-bearing capacity.

In addition, China has advanced technology in this respect, and the ink of dreams is the representative of it. Dream Ink is a liquid metal ink that can be electrically conductive and placed in a 3D printer to accurately print the PCB. This technology breaks the bottlenecks and barriers of electronic manufacturing technology, enabling printers to make electronic circuits quickly and easily at low cost.

Circuit boards are an important part of the electronics industry, and every electronic device requires a circuit board. The traditional manufacturing method requires complicated steps such as high-temperature copper film evaporation and chemical reagent etching, which is time-consuming and labor-intensive, and the cost is also high. In the future, 3D printing can be easily implemented. Will it subvert the traditional manufacturing process of electronics manufacturing?
