Supply Chain Management

The worldwide electronics supply chain enables sourcing of components, raw materials, chemicals, gases, consumables, equipment, and other manufacturing inputs spanning global networks of suppliers, distributors, and partners. Supply chain logistics, distribution, and warehouse management deliver parts where needed during production.

Compliance and Certification

Regulations, standards, and customer requirements guide the certification of quality management systems, environmental management, safety, ethics, security, material content, and other priorities. Compliance helps manage business continuity risks.

Assembly and Integration

Full assembly transforms components into functioning modules, boards, systems, and finished products. This involves:

  • Surface mount technology (SMT) automated assembly of components onto PCBs
  • Through-hole component insertion and soldering
  • Interconnecting boards, wiring harnesses, electromechanical modules
  • Integrating subassemblies like displays, chassis, enclosures, and covers into final products
  • Programming installed firmware and boot software
  • Testing subassemblies and end products
  • Repairing, reworking, and troubleshooting

Quality Assurance

Rigorous quality assurance steps validate proper function, performance, reliability, and aesthetics at all points in manufacturing including incoming, in-process, and final testing:

  • Inspecting, measuring, and testing against specifications
  • Detecting process deviations and defects
  • Burn-in stress cycling to validate reliability
  • Maintaining quality documentation and traceability
  • Issuing corrective actions to resolve issues
  • Improving processes and inspection methods

Quality is crucial for product integrity.

Sustainability and Green Initiatives

Electronics manufacturing impacts the environment through energy and water use, emissions, and material waste. Companies implement sustainability initiatives like:

  • Energy conservation and renewable energy
