Heavy copper PCB 4 layer from MOKOPCB is reliable
$28.60
This 4-layer heavy copper PCB is made of FR4, featuring 5oz copper thickness. Thick copper is used on both inner and outer layers to handle higher currents and reduce heat buildup. While four-layer structure also provides better signal integrity and allows for more complex routing in compact designs. When you apply PCBs in high-power or high-reliability applications, a 4-layer heavy copper PCB can be your ideal and trusted option.

Questions & Answers
1.How do I request a quote for my PCB project?
You can fill out our online quote form or contact our sales team via email or phone for a quick response.
2.Which design file formats should I submit for a quote?
Please submit your files in Gerber RS-274X and NC Drill formats. Make sure to compress all files into a single .zip folder, including a readme file if needed.
3.What are the benefits of a heavy copper PCB 4 layer?
4 layer heavy copper PCB offers many advantages, including better thermal performance, high current carrying capacity, improved mechanical strength, etc.
4.What are the main manufacturing challenges of 4 layer heavy copper circuit boards?
A lot of copper needs to be removed, which increases the cost. Thin traces are difficult to manufacture, while thick traces may become uneven.
5.What is the difference between heavy copper PCBs and copper PCBs?
A heavy copper PCB uses thicker copper layers (typically over 3 oz) to handle higher current, while a copper PCB uses copper as substrate to have better heat dissipation.
