Mapping out some circuitry

Printed circuit-board maker Denshi Gihan recently came up with a novel way to showcase its manufacturing skills within an attractive product. The company made a series of iPhone and IC-card train-pass cases using circuitry and components to create designs that actually conduct electricity and light up tiny LEDs.

Now, it has released its iPhone 7 designs, which include a detailed and accurate Tokyo train map and a blueprint plan for the "Star Wars" X-Wing starfighter. These are high-density printed circuit boards, so they create slim cases, and the components are encapsulated in a tough resin to protect them from damage.
