RoHS Compliant PCBs

In compliance with RoHS directives, our boards do not contain:

  • Cadmium and its compounds
  • Hexavalent chromium compounds
  • Lead and its compounds
  • Mercury and its compounds
  • PBB (Polybrominated biphenyl) compounds
  • PCDE (Polybrominated dephenyl ether) compounds

Lead Free Finishes

We provide PCBs with various lead-free PCB surface finishes:

  • Solder Finish (lead free HASL)
  • Electroless Nickel Immersion Gold (ENIG)
  • Electrolytic Nickel/Gold - Ni/Au (Hard/Soft Gold)
  • Immersion Silver, Immersion Tin (White Tin)
  • Organic Solderability Preservatives (OSP)

All of our lead-free PCBs are built from UL approved laminates which withstand the high temperature and long duration assembly cycle (in excess of 260 degrees C). These laminates are suitable for lead free assembly processes that require the laminate base material to withstand temperatures in excess of 260 degrees C or 500 degrees F for extended periods of time. High temperature laminates ensure the higher temperature cycling requirements for some PCB assembly applications.

Gold Finish

May be Electrolytic Electroless, or Immersion

- ENIG
(Electroless Nickel Immersion Gold)

2-5 micro inches. Purpose: To prevent oxidation, extend shelf life, provide a wire bonding surface (when aluminum wire is used), and used to provide an electrically conductive surface on PCBs. Used for solderability when the flatness of the pad is critical. ENIG has shelf life longer then 12 months.

- Hard Gold

Purpose: Used for Gold Fingers (minimum 30 micro inches), soldering (maximum 17 micro inches), to prevent oxidation and extend shelf life.

- Soft Gold

Purpose: Used for wire bonding (Ultrasonic minimum 2 micro inches/Thermasonic minimum 30 micro inches) and to prevent oxidation and extend shelf life.

Immersion Silver

Use for solderability purposes (2-10 micro inches). Used for solderability when the flatness of the pad is critical.

Lead Free Solder

Use for solderability purposes (2-5 micro inches). Used for solderability when the flatness of the pad is not critical.

OSP
Organic Solderability Preservatives)

Used for solderability when the flatness of the pad is critical.

White Tin (Immersion Tin)

Used for solderability when the flatness of the pad is critical.
