PCB Engineering Support Before Production Begins

A successful PCB build starts before material reaches the manufacturing floor.
Westak's engineering teams work with customers during the design and development process to identify potential manufacturing concerns, evaluate material and construction options, and help create designs that can be manufactured reliably and repeatedly. 
Westak can assist with:
  • PCB stackup development
  • Controlled impedance
  • Material selection
  • Mechanical drill requirements
  • Trace and space considerations
  • Via structures and via fill
  • Panelization
  • Tooling package requirements
  • IPC-D-356A netlist review
Multilayer PCB stackup review for manufacturability and controlled impedance

Frequent Asked Questions

Can Westak manufacture ITAR-controlled PCBs?Yes. Westak is an ITAR-registered U.S. printed circuit board manufacturer with facilities equipped to support export-controlled PCB programs. We understand the importance of protecting sensitive technical data and following applicable U.S. export control requirements. Customers can securely submit ITAR-controlled design files through our designated secure file transfer system.
Does Westak manufacture PCBs in the United States?Yes. Westak operates two U.S. printed circuit board manufacturing facilities located in Sunnyvale, California, and Forest Grove, Oregon. Our Sunnyvale facility is AS9100 certified, while our Oregon facility maintains ISO 9001:2015 certification and MIL-PRF-31032 qualification. These facilities support customers requiring domestic PCB manufacturing, quality assurance, and reliable technical support.
Can Westak help develop a PCB stackup? Yes. Westak's engineering team works with customers to develop PCB stackups based on design requirements, material availability, copper weights, dielectric thicknesses, and controlled-impedance targets. We can recommend suitable material constructions and help optimize stackups for manufacturability, performance, and production availability. Providing your design specifications and impedance requirements early in the process helps us develop the most appropriate solution.
Does Westak manufacture controlled-impedance PCBs? 
Yes. Westak manufactures controlled-impedance printed circuit boards for applications requiring consistent electrical performance and signal integrity. Our engineering team can assist with stackup development, dielectric selection, trace geometry, and impedance calculations to meet specified requirements. Controlled-impedance designs are reviewed for manufacturability, with impedance testing available as required.
Does Westak support prototype and production quantities?
Yes. Westak supports PCB manufacturing from engineering prototypes and small production runs to ongoing production requirements. Our manufacturing capabilities accommodate a variety of quantities and lead times, depending on design complexity, material availability, and production capacity. We work with customers to identify practical manufacturing solutions that support both initial development and continued production needs.
Can Westak manufacture HDI PCBs?
Yes. Westak manufactures high-density interconnect (HDI) printed circuit boards incorporating advanced technologies such as laser-drilled microvias, blind and buried vias, and sequential lamination. These capabilities support compact, complex PCB designs requiring higher circuit density and reliable interconnections. Our engineering team reviews each HDI design to confirm manufacturing feasibility, material selection, and applicable design requirements before quotation.
