Core Introduction (Matches "PCB Top/Bottom Copper Foil & Via Detail Image")
Whether you’re designing smartphones, industrial controllers, or IoT sensors, our double sided PCBs deliver the perfect balance of space efficiency, signal integrity, and durability. With copper circuits on both top and bottom layers, connected by reliable plated through-holes (PTH), we solve the “size vs. functionality” dilemma that plagues modern electronic design.

Why Choose Our Double Sided PCBs?
Dual-sided copper foil layout increases component density by 50%, making it ideal for “slim and lightweight” consumer electronics such as smartphones and smartwatches. With the option of 0.4mm ultra-thin base material, it can be embedded in narrow spaces like wearable device straps and drone bodies (Image: Installation diagram of PCB embedded inside a smartwatch).
Adopting high Tg (170℃+) FR-4 base material and ENIG surface finish reduces signal attenuation and crosstalk, supporting stable operation of high-frequency devices such as 5G communication modules and WiFi 6 routers. The via plating thickness is ≥20μm, ensuring current transmission efficiency (Image: Signal waveform comparison chart – Regular PCB vs. Our PCB).
The solder mask uses scratch-resistant and wear-resistant ink, with salt spray resistance testing reaching 96 hours; IP65 waterproof rating packaging is optional, suitable for “high/low temperature, dusty” scenarios such as industrial control cabinets and vehicle-mounted power supplies. It has passed UL 94 V0 flame retardant certification (Image: Actual application of PCB in high-temperature equipment of industrial workshops).
Compared with 4-layer PCBs, the production cycle is shortened by 30% and the unit price is reduced by 40%, suitable for small to medium batch (100-5000 pieces) customization needs. We support “rapid prototyping” service, with samples available in 24 hours and mass production delivery within 7 days (Image: Actual shot of automated production line in the workshop).
