PCB Assembly

PCB assembly forms a core part of our electronics manufacturing services (EMS). This capability can be utilized at all levels from the initial production of very low volume (NPI, EVT, PVT), rapid prototype products, through to the ongoing manufacture of complex, multi-technology PCB assembly.  With our automated SMT Assembly lines Ever Sparkle achieves more than 2.5 million SMT placement per day from 0201 sized chip components to micro BGAs.
