•  Comprehensive electrical testing and test system development for boundary scan, in-circuit test (ICT), functional test and burn in test (BIT)
•  10 Lines High Speed Siemens SMT line,D4+D4+D1,which can meet high volume requirements.



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.
