Durable 2 Layers LF HASL Heavy Copper PCB Manufacturing UL Approved

UL Approved 2 Layers Double Sided LF HASL Thick Copper PCB Manufacturing

For the heavy copper board manufacturing, LEFANG applies to RoHS and UL compliance. The copper thickness of this thick copper PCB is 2 OZ / 70 µm and the board thickness is 1.6 mm with green solder mask. And the surface treatment is LF HASL, which help to protect the PCB bared copper from oxidation. While the minimum aperture and the line width / Space are 0.2 mm.

Little knowledge - Medical Devices
Electronics contributes significantly to today's health-care industry like in diagnostic, monitoring and treatment devices. Because of the health implications associated with them, medical PCBs are held to higher standards than most other PCB types.
PCBs within the medical industry are highly specialized to satisfy the restriction of medical devices. In many medical applications, requirements like size and appearance are existed for an implant or emergency room monitor. For this reason, medical PCBs tend to be specialty high-density interconnect PCBs (HDI PCBs) or made with flexible base materials, allowing PCB to flex during use.
