Quality-Driven Printed Circuit Board Assembly Processes

To ensure our parts are delivered compliant to even the strictest requirements, our Printed Circuit Board Assembly Division typically provides the following services:

  • Review and check specifications to ensure the SMD components are properly packaged, stored and handled per the MSL classification.
  • Identify sensitive components to avoid thermal and mechanical damage during SMT processes in accordance to the latest J-STD-020 standards, including compliance at higher temperatures for Pb-free and lower temperature
    Sn-Pb assemblies.
  • Review components specifications for ESD, MSL handling and reflow profile in accordance to IPC J-STD-020 standard.
  • Evaluate the PCB layout including board thickness, pad size, surface finishing, solder mask alignment, component density, pitch and orientation.
  • Design the stencil thickness and hole size, use of solder paste material and reflow profile setup to ensure the solder joint meets IPC-A-610 standards.
  • If needed, fine tune the SMT process based on AOI, X-ray inspection and testing data.
