•fine pitch surface mount (SMT) to 0.8mm 
•18:1 high aspect ratio drilling and plating 
•carbide drilling down to .008" tool diameter 
•high-density ball-grid-array (BGA) 
•in-house UV:YAG laser for microvias 
•press fit compliant and pin-through-hole (PTH) 
•15+ distinctive PWB base materials 
•multiple surface metal finishes and development 
•substrate boards for chip packaging
