Reliable double-sided PCBs when your project needs both density and durability
If you need more routing than a single layer but don't require multi-layer production, double-sided printed circuit boards (PCBs) strike the best balance between performance, cost and lead time. Communica stocks a practical selection of ready-made and prototyped double-sided boards, plus accessories to finish and assemble your board locally - ideal for makers, students and engineering teams across South Africa who need predictable availability and VAT invoices for procurement or educational projects.
Why choose local stock and branch pickup
Local stock cuts lead times: collect from our Samrand head office or one of our branches in Pretoria and Cape Town, or request an account quote for larger runs. We carry common sizes, FR-4 blanks, plated-through via kits and prototype assembly accessories so you can move from schematic to working hardware without import delays or unexpected customs hold-ups.
- Immediate pickup at Samrand or branch collection - see branch hours Branches & Trading Hours.
- Stock of standard board sizes, pre-drilled mounting holes, and solder mask options in popular quantities.
- VAT invoicing and account quotes for schools, labs and procurement teams.
Common specifications and what they mean for your build
When choosing a double-sided board, three spec callouts determine fit for purpose: copper weight, board thickness and via type. Below is a quick reference to help you decide.
| Spec | Typical Options | Practical impact |
|---|---|---|
| Copper weight | 1 oz, 2 oz | Higher copper supports more current and heavier traces. |
| Board thickness | 1.0 mm, 1.6 mm | Thicker boards are more rigid; 1.6 mm is industry common. |
| Via type | Plated-through, non-plated | Plated vias give reliable electrical connection between layers. |
Specification callouts we recommend for prototyping
For mixed-signal student projects and small production runs choose FR-4, 1 oz copper, 1.6 mm thickness with plated-through vias. If board current is above a few amps, opt for 2 oz copper or add wider traces - see the trace current table below to plan your layout before ordering or ordering accessory kits from our collections.
| Trace width | 1 oz copper | 2 oz copper |
|---|---|---|
| 1 A | 0.25 mm | 0.15 mm |
| 3 A | 0.8 mm | 0.45 mm |

Quick wiring note and layer planning (ASCII)
For common through-hole components, route power on the bottom layer and signals on the top layer, using vias to feed pins. Example:
Top: R1 ---+------- U1 pin2
| |
Via o o Via o
Bottom: GND ---+------------ U1 pin1
