0.5/1/2/3/4 oz Standard Copper Thickness PCB
$90.90
Standard copper thickness PCB generally refers to PCB with standard 0.5oz, 1oz, 2oz, 3oz, 4oz per square foot of copper. Among them, 1 oz copper PCB is most normal one. A standard 1 oz copper PCBs are structured conductive layers, core or substrat layer, dielectric layers, and surface finish. They are ideal for digital boards, consumer electronics like phones, low-power circuits like sensors, and more.

4. Can I mix Rogers layers with a copper core?
Yes, hybrid PCBs are possible, and you can inquire with our expert for more information.
5. Can I use the standard copper thickness PCB for RF power amplifiers?
Yes, but you need to choose copper thickness based on frequency. It is ok to use 1 oz copper for <10W, <1 GHz, but for high power RF PAs, you may need to choose 2 oz copper PCB for loss reduction and heat dissipation.
6. Why does the 1oz PCB overheat even at low current?
You can first check the near board edge for better heat dissipation, and see whether there is inadequate grounding.
7. What’s a typical 4-layer copper core PCB stack-up?
Layer 1 (Top) is the signal layer with 1 oz copper for RF components; layer 2 is a solid ground plane for RF shielding; layer 3 is a power plane; layer 4 is another signal layer; the next two layers are the dielectric layer and the copper core layer.
8. Why is 1 oz (35 µm) the most common copper thickness?
The 1oz copper thickness strikes a balance between conductivity, manufacturability, and cost. It provides sufficient current-carrying capacity for most applications and maintains trace resolution, offering wide availability and good performance.
9. Does thicker copper improve PCB’s durability?
Yes. Thicker copper increases mechanical strength to reduce pad and trace lifting, improves thermal performance to prolong the board’s lifespan, and handles higher current without overheating.
10. How does heavier copper (3 oz, 4 oz) impact PCB manufacturing?
Heavy copper provides advantages in high-power applications but also introduces some manufacturing challenges. Thicker copper requires wider trace spacing and specialized fabrication and plating. It also needs to manage challenges like delamination, hole voids, and CTE mismatch.
