The double-sided PCB is one step above one-sided in its complexity. The double-sided PCB requires through holes to provide better anchoring for welded components and electrical continuity from front to back. Most designs require double-sided welding mask along with a silkscreen layer for component designators. Often double-sided design uses mixed through-hole (PTH) and surface mount (SMT) technologies.

Manufactured with state-of-the-art technology, double-sided PCB is filled with electronic components and surface mount on both sides. It comprises the making of layers made of thin sheet of copper, coating through holes, white serigraphy and green solder. Through engraving, a temporary mask is applied across the PCB, leaving only the required copper traces that go to the opposite side of the plate through holes.

Single-sided flexible PCB

Flexible single sided PCB construction with a laminated polyimide cover film for copper allowing access on one side only. A single conductive layer, glued between two insulation sheets or discovered on one side.

Application:

Optical Pick-up for A / V and Computer
Camera
Capstan Motor for Camcorder and VCR
Mobile vibration engine
Floor motor
