Calculations, routing tips and wiring examples
Simple calculations help size traces and thermal handling. Use Ohm's law when estimating current and power dissipation:
V = I * R | P = I * V = I^2 * R
Example: a 2 A supply through a 10 mm trace (1 oz copper, ~0.5 mm width) may need wider copper. Use online calculators or request 2 oz copper for power sections. When in doubt, increase trace width or add parallel traces on both sides linked by vias.
Simple ASCII wiring diagram for a double-sided jumper area
Top layer: VCC ---[R]----+-----> signal out | |Bottom: GND ---[via]---+-----> sensor GND
This shows a top-layer resistor and a via tying the bottom layer ground plane; keep these connections short and place thermal reliefs for easier soldering on prototypes.
Troubleshooting and assembly notes for local workshops
Common issues and fixes observed in student labs and maker spaces:
- Cold joints on PTH: Use correct soldering iron tip and pre-tin component leads; heat both pad and lead simultaneously.
- Mis-routed ground: Stitch ground with several vias rather than a single via to avoid noisy analog readings.
- Drill misalignment: Confirm gerber drill map and panelisation with your fabricator before the first run.
Communica supports both hobbyist and procurement workflows - request VAT invoices for institutional purchases and account quotes for larger orders. See our company background for purchasing confidence on the About Us page.
Compatibility & accessory bundles
When ordering components for double-sided boards, consider bundled purchases: header kits, decoupling capacitor packs and PCB standoffs. Bundles reduce iteration time in university labs and accelerate prototype builds for robotics teams. Check connector, enclosure and tool categories on the main buy-double-sided-boards-south-africa to pair board designs with mechanical and testing gear.
Objection handling: If you worry about lead times, Communica's Samrand warehouse and branch pickup reduce delays for most stocked components. For custom PCB fabrication, combine local stock parts with staged delivery and ask for a production ETA when placing quotes. Technical teams can request sample BOM checks before ordering to avoid re-spins.
Summary and next steps
Double-sided boards provide the most practical balance between complexity and capability for South African makers, students and engineering teams. Use the spec guidance above to specify copper weight, trace geometry and via strategy; use stitched ground pours and local accessory bundles to reduce assembly time. When you are ready, verify stock and pickup options or request a quote to align lead times and VAT invoicing.
