Key Considerations for Selecting a Robotics PCB/Assembly Partner

Here are some of the most important factors robotics companies should evaluate when selecting a PCB and assembly manufacturing partner:

  • Technical capabilities – Assess the partner’s expertise manufacturing the types of boards and assemblies specific to your robotics application – high layer count, HDI, flex/rigid-flex, etc. Look for demonstrated experience supporting complex robotics and advanced electronics.
  • Quality and reliability – Robotics operate in rugged, high-stress environments. Partner with a manufacturer that follows IPC standards, is certified to ISO quality standards, and has a track record delivering high-reliability PCBs/assemblies.
  • Prototyping support – The ability to iteratively prototype PCB and electronics design is crucial during development. Look for partners that offer quick-turn fabrication and assembly for prototypes.
  • Mix-flexibility – Many robotics involve low/medium volumes but high product mixes. Select a partner optimized for high-mix, low-volume production.
  • Scalability – As your robotic product scales to higher volumes, your partner should offer a scalable framework to graduate from prototype to volume production.
  • Testing capabilities – Rigorous testing of PCBs and assemblies is key to ensuring reliable performance. Look for partners with strong testing capabilities like ICT, flying probe, AOI, X-ray, etc.
  • Supply chain management – Having a partner that helps manage procurement and sourcing of components can be a major advantage in electronics manufacturing.
  • Design support – The best partners offer design for manufacturing (DFM) feedback and work collaboratively with your engineers early in the design process.

Selecting the correct PCB and assembly, along with effective supply chain management and collaborative design, not only simplifies manufacturing but also enhances the success and competitiveness of your robotics products.
Moreover, efficient supply chain management is crucial for securing timely and cost-effective access to essential components. Streamlining the supply chain reduces lead times, optimizes inventory management, and minimizes production delays, making the manufacturing process more efficient.
