Schematics – Circuit Diagrams are yet another requirement which help the EMS provider to put together an error-free assembly.

The other factors to keep in mind in choosing the outsourcing PCB Assembly partner, is to check for their credentials related to:

  • Industry-specific needs – It is important to see if the company meets industry regulations and standards
  • On-time delivery – This will significantly impact your time-to-market, which is a great source of competitive advantage.
