Capabilities overview

We manufacture your PCBs in our facilities in Silicon Valley. With our newest facility—70,000 square feet of the best PCB manufacturing technology available—it’s no wonder we’re the most trusted source of PCBs for consumer electronics.

  • 2, 4, 6, 8-layer boards
  • 4-mil trace/space
  • FR-4 material, 0.062” thick
  • HASL or ENIG finish
  • Green solder mask, white legend
  • BOM check
  • DFM & DFA checks by experienced engineers
  • Assembly on both sides

Product applications

Sierra Circuits’ best-in-class PCBs can be found in a variety of consumer and household electronics, including:

  • Major appliances, such as
    • Refrigerators
    • Washers and dryers
    • Dishwashers
    • Air conditioners
    • Water heaters
  • Consumer electronics, such as
    • Televisions
    • Audio equipment
    • Computers and laptops
    • Wearables and watches
  • Small home appliances, such as
    • Coffee makers
    • Rice cookers
    • Electronic toothbrushes
    • Vacuum robots

Rigorous testing and inspection for PCB for Electronics

PCBs for consumer electronics need to survive constantly changing environmental conditions and vibrations without any setback in performance. To ensure that your PCBs are functioning optimally, we can provide comprehensive testing and inspection throughout the design and manufacturing process.

Before manufacturing:

  • DFM & DFA checks
  • BOM checks
  • Special stack-up help / NPI review
  • Component engineering assistance and procurement

After manufacturing:

  • Functional inspections
  • Thermal cycling tests (TCT)
  • Thermal shock tests (TST)
  • Temperature-humidity bias tests (THB)
  • AOI report or visual inspection report
  • Flying probe or in-circuit testing report

Documentation for consumer electronics PCBs

Regulations are especially difficult if you want your product to have a global reach. For safety certifications like UL / ISO 60335-1 and you can quickly have respins running away on you with test after test, prototype after prototype. Lead-free PCBs? Can’t forget RoHS to satisfy the European market!

Following is the list of documents that Sierra Circuits can provide for your consumer electronics PCBs:

  • Certificate of conformance
  • UL certification
  • Build to IPC class 2 or class 3 specs
  • Material specifications
  • Reflow profile copy (included with first article)
  • Photo requirements
  • First article inspection report
  • IPC J-STD-001E
  • Record of calibrated tools used during manufacturing
  • AOI report or visual inspection report
  • Flying probe or in-circuit testing report
  • Ionic cleanliness test report

Missing something? We probably have that covered too. Visit our certifications page for a full list of our regulatory documentation.
