Super PCB Now Offering High Quality PCB Surface Finishes

Leading PCB supplier, Super PCB, is now offering a variety of quality PCB surface finishes. PCB surface finish is the coating between the PCB and components that provides a solderable surface for components and protects the exposed copper circuitry.

Super PCB offers a variety of surface finishes, including:

  • HASL(hot air solder leveling )/HASL lead-free: Advantages: Low cost, widely used, Leaded or lead-free, re-workable, long shelf life. Disadvantages: uneven surface, not good for PTH, not good for fine-pitch, thermal shock.
  • ENIG (Electroless Nickel Immersion): Advantages: flat surfaces, good oxidation resistance, and good for PTH, lead-free, long shelf life. Disadvantages: higher cost, black pad, does not wet as evenly.
  • ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold): Advantages: black pad free, lead-free, long shelf life. Disadvantages: higher cost, does not wet as evenly.
  • Immersion Silver: Advantages: flat surface, good solderablity. Disadvantages: tarnishes, easily scratched.
  • Immersion Tin: Advantages: flat surface, lead-free, low cost. Disadvantages: Not good for PTH, contains Thiourea (environmental concerns).
  • OSP (Organic Solderability Preservative): Advantages: flat surface, re-workable, lead-free, low cost. Disadvantages: cannot measure thickness, not good for PTH, short shelf life.

Super PCB offers USA manufacturing to support ITAR requirements. The company’s manufacturing facilities are RoHS compliant, ISO 9001 and TS16949 certified, and UL listed.
