Our manufacturing team uses advanced quality processes. For example, our SMT lines feature automated testing of passive components to prevent defects. We use unique thermal profiles for each board design to optimize soldering. We perform full automated optical inspection of every board, tracking results electronically by serial number, and use the data to pinpoint when and where defects happened and determine corrective actions. All manufacturing team members can suggest improvements to processes in their own areas of expertise using an electronic change request system.
Our in-house design team is actively involved in the testing of your boards, whether it’s your design or ours. They work with manufacturing engineers on root cause analysis and can talk with your design engineers about problem areas or suggested improvements.
Our quality department manages rigorous incoming, in-process and final inspection of materials. We are implementing statistical process control (SPC) for our supplier base and internal processes in 2017.

Quality Systems and Processes

  • Incoming component validation with barcode scanning to confirm with approved vendor list
  • Automated optical inspection (AOI) of all boards including polarity, part numbers, solder bridges and part alignment, with electronic tracking of results
  • X-ray of leadless packaging
  • First article inspection at every stage of production
  • First-pass yield monitoring throughout the day, every day
  • Internal ISO audits every quarter with audit team
  • Regular audits of other quality-related areas such as ESD protection
  • ERP system for timely delivery, labor tracking and online documentation
  • Regularly scheduled training
  • Robust preventative maintenance database that schedules all manufacturing equipment maintance
  • Electronic change request (ECR) system to identify opportunities for higher quality and efficiency.
