FR4 Double Sided PCBs - Best Sellers

FR4 double sided PCBs are used across consumer electronics, telecommunications, medical devices, automotive, aerospace, industrial automation, and military applications. Their versatility makes them suitable for everything from PC motherboards and mobile devices to medical imaging equipment, satellite systems, and automotive control modules.

FX PCB offers standard copper weights from 0.5 oz up to ultra-heavy 20 oz. Standard (0.5–1 oz) suits general electronics, medium (2–4 oz) handles moderate power loads, heavy (5–10 oz) supports industrial and military equipment, and ultra-heavy copper (10–20 oz) is used in high-power modules and EV systems.

Available surface finishes include HASL, Lead-Free HASL, Immersion Gold (ImAu), Immersion Silver (ImAg), Immersion Tin (ImSn), Hard Gold, and OSP. Each finish offers different advantages for solderability, shelf life, and application environment, with ENIG (ImAu) preferred for fine-pitch and high-reliability assemblies.
