Nelco PCB by Surface Finish (6)

  • ENIG Nelco PCB

    We use the most advanced ENIG technology to improve the solderability of copper contacts and plated through-holes, providing you with the best-finished product.

  • Immersion Tin Nelco PCB

    This Nelco PCB will provide low resistance and corrosion protection to the PCB in your design. This is a lead-free PCB alternative tin applied over the copper layer of your board.

  • Immerion Silver Nelco PCB

    The Immersion Silver Nelco PCB is an excellent choice for the electrical connection of electronic components, mainly for supporting and interconnecting different boards.

  • ENEPIG Nelco PCB

    Has copper from an electroless nickel to enhance mechanical strength. Three layers of coating are applied onto the copper pads by a twin-extruder nozzle across a PCB.

  • Hard Gold Nelco PCB

    Hard Nelco PCB has gold applied on top of the nickel, which attaches well and does not easily disintegrate. So you can rest assured knowing that your PCB will withstand the test of time.

  • Lead-Free HASL Nelco PCB

    Lead-Free HASL Nelco PCB. Lead-free HASL Nelco PCB reduces the amount of lead used, which reduces the risk of lead poisoning. Better for end-users and the environment.

Nelco PCB by Type (6)

  • Single-Sided Nelco PCB

    Nelco Single-sided PCBs are designed to contain only one layer of conductive material only and are best suited to low-power or low-noise applications.

  • Double-Sided Nelco PCB

    Double-sided Nelco PCB is two-sided traces on one side and conductive copper on the other side. Attach copper and other materials on both sides of the PCB.

  • Multilayer Nelco PCB

    A multilayer printed circuit board technology that allows you to have a circuit board with at least three or more layers of material in the center of the PCB.

  • Rigid Nelco PCB

    Rigid Nelco PCBs have solid, inflexible features that prohibit them from being twisted or deformed to interconnect electronic components in electronic devices.

  • Flex Nelco PCB

    Flexible-based PCBs that are printed in a patterned arrangement of components. Designed to be used in tight spaces and to be printed on a flexible substrate.

  • Rigid-Flex Nelco PCB

    Rigid-Flex Nelco PCB is a combination of rigid and flexible circuit boards that are permanently combined. Promotes both stability and flexibility.
