Printed Circuit Boards (PCBs) and Protoboards


Majority of the electronics circuits are wired into Printed Circuit Boards (PCBs). These boards are the integral part of circuit package design, providing an interconnection system and a base for mounting discrete and integrated circuits. These boards are made of plastic laminate or base, over which a thin metal foil (usually copper) is bonded with phenolic or epoxy resin. The metal foil of a PCB can be on one side for single-sided boards or the metal clad on both sides for double-sided boards.

Below are some of the PCBs that we have:

Ordinary PCBs


Alexan offers a cost-friendly alternative to the presensitized PCBs with these ordinary PCBs. These boards come either single-sided or double sided in various sizes as listed below:

  • 4x4
  • 4x6
  • 4x12
  • 6x12
  • 12x12

Presensitized PCBs


Prototyping has never been easier with Alexan's Presensitized PCBs!

Presensitized positive (+) acting printed boards now available in various sizes. These boards are coated with a highly sensitive photoresist film that allows short exposure time, typically 60 to 90 seconds using UV exposure unit or 6 to 10 minutes using Fluorescent Lamp.

These boards are ideal for prototyping and small production runs. No negatives or darkroom are needed since they can be exposed directly from art transparency. A light protective cover allows them to be cut into specific sizes without exposing other areas of the board.

The boards are 1.6-mm in thickness and come in various sizes as listed below:

  • Single-sided:
    • PP 4x6
    • PP 6x10
    • PP 12x12
    • PP 12x18
  • Double-sided:
    • GD 4x6
    • GD 6x10
    • GD 12x12
    • GD 12x18
