Frequently Asked Questions
We optimize material selection, streamline production process and make the best use of panels. All of these ensure that our products are premium while also saving costs.
Generally, the lead time for this 4 layer 175 μm heavy copper pcb is 2-3 days longer than that of standard 4-layer circuit boards.
We construct this PCB with high-Tg FR-4 as the base material, electro-deposited (ED) copper foil, and standard epoxy-based solder masks. These materials support good performance while keeping the board cost-effective.
The 175 μm (5 oz) copper thickness allows high current (typically 50 A or above) to flow, depending on the trace width and temperature rise limits.
Yes! Our experts analyze DFM for free and in just 24 hours to ensure your design is correct, and to optimize both yield and cost efficiency.
PayPal, T/T (bank transfer) or any of the major credit cards are acceptable. When ordering in large quantities or making repeat orders, we provide more flexible payment terms.
