Fig. 5: MM-AM of USB-A powered squid-shaped multilayer embedded electronics.

a Exploded CAD model view showing the different conductive layers (yellow) and polymer layers (green). b Isolated view of the longest metal trace of length, 134 mm, and two metal via (red) of the height of 1 mm. c Printed result of the squid-shaped demonstrator showing both embedded conductive layers (right) and highlighted single conductive trace (placed against light source) (left). d Top view of electrical connections to 555-timer pins (A). Directly soldered SMD placed in a polymer slot with conductive traces printed on contact pads (B).
