Look, when you’re dealing with high-power electronics, standard PCB copper thickness just doesn’t cut it anymore. That’s where PCBSYNC’s 3 oz copper PCB services come in handy.
Most everyday circuit boards use 1 oz copper, which is fine for your typical gadgets and consumer electronics. But if you’re building power supplies, motor controllers, or anything pushing serious current, you need something beefier. That’s the whole point of 3 oz copper – it can handle the heat and current without turning your board into a fire hazard.
PCBSYNC specializes in manufacturing these heavy copper boards, and honestly, it’s not as straightforward as it sounds. Thicker copper means different etching processes, more careful handling during fabrication, and tighter quality control. The plating has to be uniform, the traces need proper spacing to avoid shorts, and you can’t just run your standard manufacturing process and hope for the best.
What makes their service useful is they handle the tricky parts. They’ve got the equipment to work with that extra copper weight without compromising on precision. You still get decent trace definition even with the thicker material, which matters when you’re trying to fit everything onto a reasonable board size.
The 3 oz option sits in a sweet spot – thick enough for serious power handling but not so extreme that it becomes prohibitively expensive or difficult to work with. Some applications need 4 oz or even 6 oz copper, but for most power electronics projects, 3 oz does the job.
Their manufacturing process includes proper impedance control, which is crucial if you’re mixing power traces with signal traces on the same board. They also offer different laminate options depending on your thermal requirements.
Bottom line: if you’re pushing 10+ amps through your circuits, dealing with high-frequency switching, or just need better thermal dissipation, PCBSYNC’s 3 oz copper service is worth considering. It’s not fancy, it’s just practical engineering for applications that demand it.
