Super PCB, a single source for high quality printed circuit boards (PCBs), is pleased to announce that it offers 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, reworkable, long shelf life. Disadvantages: uneven serface, not good for PTH, not good for fine-pitch, thermal shock.
- ENIG (Electroless Nickel Immersion): Advantages: flat surfaces, good oxidation resistance, 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, reworkable, lead-free, low cost. Disadvantages: cannot measure thickness, not good for PTH, short shelf life.
