World's First Ultra-Thin Multilayer Circuit Board

Posted by Hemos on from the first-to-the-post dept.

neutron_p writes "Seiko Epson has developed the world's first 20-layer circuit board. Multilayer circuit boards are normally produced by using a photolithography. However, the industry has struggled to produce thin, lightweight, high-density multilayer circuit boards. Seiko Epson uses an inkjet-based manufacturing process, which has many advantages over a traditional photolithography process."

    It sounds like it should be somewhat flexible, although I doubt you would want to move it much because the ink might flake off or crack. It looks like it could produce curved and bent boards though. That would be great for putting electronics in odd shaped housings.

    I want the consumer version. This would make it much easier for the hobbiest like myself to make boards. Just print and use. I could see printing out the board on a thin film and then glueing it to a normal thickness material. The only problem I see is how to solder to it. It's a conductive ink so you might need a low-temperature solder or some other method so as to not burn it.

    consumer electronics weren't already hard enough to repair. This will take them to a whole new level of discard-and-replace.

    Once upon a time there were technicians that could take any piece of consumer electronics, and given a good repair manual, trouble shoot the problem and replace the offending component.

    This creates a monopoly of sorts - since repair is impossible, the manufacturer has sole control over their product, so their profit margin increases. It behooves them to create products that cannot be repaired.

    The article stated that one of the advantages to this technology is the large reduction in the amount of chemicals used to produce a circuit board. This would be a big advantage for mass production of cirucit boards. A large costs for circuit board manufacturers is the handling of the chemicals and waste products, the acids, photosensitive liquids and such. One would have to have a considerable knowledge of the costs involved in each process, but you can bet that if this process is cheaper, or looks like it will be cheaper, the new process will be used.


    I can see this technology as starting point of a pcb manufacturing revolution. Connectors directly molded on to the pcb.
