Construction of Double Sided PCB

The construction of a double sided PCB is similar to that of a single-sided PCB, with some exceptions where certain layers are laminated on both sides of the board.

●Substrate: the material is mainly glass fiber epoxy resin. The type of substrate defines whether the PCB board is a flexible or rigid PCB.
●Copper Layer: copper layer is laminated on both sides of the substrate.
Solder Mask: the solder mask is placed over the copper foil on both sides of the board to provide protection.
Silk Screen: There is a silk screen above the solder mask on both sides of the circuit board, which is mainly used to add symbols and characters on the circuit board.

How to Make Double sided PCB?

1. Use any PCB design software or CAD tool to make the top and bottom layout of the PCB. Print both layouts on separate high quality glossy paper.Adopt double-sided copper plated, fiberglass PCB substrate and cut to desired size.

2. Use a cloth iron to iron the top PCB layout printed on top of the circuit board.Remove the iron and use a scrubber to remove the laser ink from the PCB track.

3. Drill the required holes.Clean the other side of the board.Repeat steps 2 to make sure the layout on both sides is properly aligned.

4. Place the board in a copper chloride solution (CuCl3 or FeCl3) for about 20-30 minutes to allow the copper to etch away.

5. To make the holes conductive or plated through holes, use conductive ink or a conductive pen with a fine tip. Coating a green solder mask to both sides of the board.

  • Next, the copper is removed too and the blueprint is revealed.
  • The resist covers the laminate panel and then hardened by ultraviolet light.
  • Resist and laminate is aligned and fused using ultraviolet light.
  • Photoresist indicates pathways where the copper will run.
  • The board is then cleaned and left to dry.

IV. Getting rid of the unneeded copper:

  • Involves removing unwanted copper.
