Sunstone Circuits Adds ENIG Process to In-House Offerings

MULINO, Ore.— Sunstone Circuits®, a provider of printed circuit board (PCB) prototype products and services, recently added an electroless nickel immersion gold (ENIG) process to the in-house offerings at its Mulino, Oregon manufacturing facility. The semi-automated line is custom manufactured by RK Fabrication and will be using chemistry by Dow Electronic Materials. By adding this process in house, Sunstone reports that it will be able to decrease the minimum lead time from 1 week to a 2 day minimum on PCBpro® Full Feature orders as well as having more control over pricing.

“We are excited to be adding this process to our in-house list of offerings, as it will benefit our customers in many ways,” said Sunstone Director of Operations, Nancy Viter, in a press release. “As the demands on PCBs continue to drive smaller and tighter features, lead-free initiatives and reliability at assembly become even more important. We can now offer one of the most versatile surface finishes to our customers and make it quicker and easier to order, at a greater value.”

The new in-house ENIG Process complements Sunstone’s growing suite of PCB offerings, which include extended lead times for PCBExpress® Quickturn; an on-time guarantee; bundled assembly, slots, cutouts, and expanded drill sizes on PCBExpress Quickturn and PCB123®; SMT stencils with or without nano coating; and ITAR Registration, among others.

Sunstone Circuits (sunstone.com) has more than 40 years of experience in delivering PCB prototypes. The company says that it is “committed to improving the prototyping through production processes for the design engineer from quote to delivery.”
