Mulino, OR – March 19, 2013 – Sunstone Circuits®, the leading printed circuit board (PCB)prototype solutions provider, has enhanced their services by expanding the drillsizes available on their Quickturn service, which offers a fast turnaround on high-quality, 2 to 6-layer printed circuit boards. Quickturn service nowoffers finished hole sizes from 0.008” to 0.250”, with a tolerance of +/-0.005”.

With the expanded drill sizes on any Quickturn order, Sunstone customers will now have even greater confidence in the quality and consistency of their QuickturnPCBs. Design engineers will experience several added benefits from this new expanded service: 

• Faster order entry using your file’s specificfinished hole sizes
• Smaller vias now possible on two layer boards
• More exact component fitting for easierassembly
• Reduced time processing orders, fewer holddelays
• Easier to move from prototype to production
• No special changes to files will be neededfrom designers or engineers  - a closerrepresentation of production runs, which opens ordering options to all customers

"We listened to our customers’feedback and we realized that offering expanded drill sizes on our Quickturnproduct line would allow our customers much more flexibility when designingtheir printed circuit boards,” said Nancy Viter, Director of Manufacturing at Sunstone Circuits. “The expanded set of drill sizes gives the design engineer closerthrough-hole tolerances than ever before on Quickturn prototypeboards. With no drill file conversions, there are no restrictionsand there is less worry when designing PCBs.”

This latest new product offering joins a growing suite of PCB solutions that includes Bundled Assembly, Slots & Cutouts on Quickturn, PCB Design Software, ITAR Registration and Stencils, to name a few.
