Southrock Engineering Services

Southrock Engineering is a US-based engineering firm that designs and assembles custom PCBAs, as well as custom cables and wire assemblies, box build assemblies, prototyping, and reverse engineers printed circuit boards.

Custom Printed Circuit Board Assembly (PCBA)

We work with companies that require precision, repeatability, and quality documentation.

We design and assemble:

  • Analog, digital, and microprocessor-based PCBAs
  • SMT and through-hole assemblies
  • Single-layer to multi-layer boards
  • Sub-assembly integration and testing

Custom Cable & Wire Harness Assemblies

We manufacture with virtually all cable types and can support low- or high-volume production.

For Sunnyvale manufacturers in automation, marine systems, or electronics, we provide:

  • Cut, strip, slit, crimp, and termination services
  • Multi-conductor cable assemblies
  • Custom wire harness builds from schematics
  • IPC-standard soldering and inspection
  • Sub-assembly integration & testing

Reverse Engineering for PCBAs

Our US-based engineers can reverse engineer your printed circuit board and restore production control.

If you’re dealing with:

  • Obsolete components
  • Offshore vendors holding your design
  • Limited documentation
  • Supply chain interruptions

Custom Box Build Assembly Services

We integrate PCB assemblies, power components, and interface elements into a single, cohesive unit.

Every build is customized to your specifications, ensuring proper fit, thermal management, and long-term reliability. These systems are commonly used in:

  • Industrial machinery
  • Control panels
  • Medical and safety devices
  • Monitoring and automation devices

PCBA and Cable Assembly Prototyping

We provide custom PCBA and cable assembly prototyping services designed to move your product from concept to working hardware, quickly and accurately.

  • Validate your design in a physical format
  • Identify issues early and reduce costly revisions
  • Test performance in real-world conditions
