Why choose local double-sided PCBs from Communica
For prototype runs, student projects or low-volume production, double-sided printed circuit boards (PCBs) offer the density and routing flexibility you need without the complexity of multilayer fabrication. Communica stocks a range of ready-made and quick-turn double-sided boards plus accessories so you can move from breadboard to soldered assembly faster - with local availability, branch pickup and VAT invoices for procurement and academic reimbursement.
What you get - practical benefits, not buzzwords
Immediate access to common board formats, through-hole and surface-mount pads, and standard FR-4 substrates. Benefit highlights: faster iteration (avoid long import lead times), in-person technical help at our Samrand or Pretoria branches, and easy account quotes for departmental purchases. For brand and component cross-references, explore our Shop by Category to match boards with connectors, headers and assembly tools.
Key specification callouts to check before ordering
When choosing a double-sided board, focus on these parameters first: board thickness, copper weight, pad finish, drill size tolerance, and soldermask colour. Matching these to your assembly method reduces rework and ensures parts fit correctly.
| Spec | Common Options | When to pick |
|---|---|---|
| Board thickness | 1.6mm, 1.0mm, 0.8mm | 1.6mm for robust assemblies; 1.0mm for enclosures with tight clearance |
| Copper weight | 1oz, 2oz | 1oz for most hobby projects; 2oz for higher current traces |
| Pad finish | HASL, ENIG | HASL for standard soldering; ENIG for fine-pitch or plated through-hole reliability |
Compatibility guidance and accessory bundles
Choose boards compatible with your component footprint: measure pad pitch for SMD packages and confirm hole sizes for through-hole parts. We assemble accessory bundles that include flux, solder, headers, and pre-cut standoffs to streamline build days for labs and makerspaces. For component matching and brand choices, see our Shop by Brand page to pair PCBs with trusted parts.
Quick practical example: converting a breadboard design to double-sided PCB
Step 1: Export your schematic and place footprints with 0.1in grid alignment. Step 2: Route high-current traces on one side and signal traces on the other where possible. Step 3: Add vias to move signals between layers and keep track of thermal reliefs for ground vias.
Top layer trace -> Via -> Bottom layer trace
For standard calculations use Ohm's law and power rules to size copper width: I = V / R and P = I*V. For a 1A trace on 1oz copper, refer to standard trace-width charts - or ask our technical team at the Samrand branch for guidance found on our Branches & Trading Hours page to plan a visit.
