3D printing technology applied in PCB manufacturing

3D printing technology is receiving more and more attention in PCB manufacturing. 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 create 3D structures made entirely of liquids through 3D printing technology paves the way for the manufacture of electronic devices that require 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's still a tube. Or we can shape the water into an ellipsoid, it's still an ellipsoid," Russell said.
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 use external force to flatten the material so that it can instantly break the stability of the super soap and change the shape of the waterline. This structure has a high load-bearing capacity,” he said.

  In addition, China has advanced technology in this respect, and Beijing Dream ink is one of them. 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?
