Product Details Matte Black Double-Sided FR4 PCBMatte black double-sided FR4 PCB with a custom black core, designed for inverter, power conversion and industrial control applications. The board combines a two-layer FR4 construction with 1–2oz copper and multiple surface finish options.Double-Sided FR4 ConstructionThe PCB uses a double-sided FR4 structure with two copper layers. This construction provides more routing space than a single-sided board while maintaining a relatively simple and practical PCB structure.The standard board thickness is 1.6mm, with customized thickness options available for different product requirements.Matte Black Solder Mask and Black CoreThe board uses a matte black solder mask together with a black FR4 core. The black core is designed to reduce light transmission and provide a consistent appearance across the PCB.The matte black finish can also be selected for products where PCB appearance is an important consideration.1oz to 2oz CopperCopper thickness is available from 1oz to 2oz. The copper weight can be selected according to the current-carrying requirements of the inverter or power conversion circuit.Fine-Line PCB ManufacturingThe manufacturing process supports a minimum line width and spacing of 0.15mm / 0.15mm.This provides sufficient layout capability for compact two-layer inverter boards and other industrial electronic circuits.Multiple Surface Finish OptionsSeveral surface finishes are available, including ENIG, HASL, OSP and immersion silver.The surface finish can be selected according to the PCB assembly process, soldering requirements and final product specifications.Electrical Testing and InspectionThe PCB manufacturing process includes 100% electrical testing, with flying probe or fixture testing available.AOI inspection and final visual inspection are also supported. Impedance testing can be provided when required by the PCB design.ApplicationsSolar InvertersThe PCB can be used for control and power circuits in solar inverter equipment, depending on the system architecture and electrical requirements.Power InvertersThe double-sided FR4 construction and 1–2oz copper option make the board suitable for custom power inverter circuits.Power ConvertersThe PCB can be customized for DC/DC converters, AC/DC power conversion equipment and related electronic power systems.Frequency ConvertersThe board can be used in frequency conversion equipment and motor-related power electronics.Industrial Control SystemsCustom black FR4 PCBs are suitable for industrial control boards and electronic control equipment requiring customized dimensions and circuit layouts.Power ElectronicsThe board can support various power electronic circuits where a two-layer FR4 PCB with customized copper thickness is appropriate.Technical SpecificationsPCB Type: Double-Sided FR4 PCBPCB Layers: 2 layersCore Material: Black Core FR4Standard Board Thickness: 1.6mmOptional Board Thickness: 0.4–3.2mmSolder Mask: Matte BlackSolder Mask Thickness: 10–25μmCopper Thickness: 1–2ozMinimum Line Width/Spacing: 0.15mm / 0.15mmSurface Finish: ENIG, HASL, OSP, Immersion SilverTesting: 100% Electrical Test, AOI, Visual InspectionImpedance Test: Available on RequestManufacturing: Prototype and Mass ProductionLead Time: 3–7 Working DaysQuality Standard: IPC-A-610 Class 2/3Compliance: RoHSCustom Black Core FR4 PCBThe PCB can be customized according to Gerber files and specific requirements for board size, thickness and copper weight.Prototype and mass-production services are available, allowing customers to verify the board design before moving to volume production.Matte Black PCB for Power ElectronicsThis matte black double-sided FR4 PCB is designed for inverter, power converter and industrial control applications.
