8_layers_HDIShengyi

8L HDI – materials: FR-4 Shengyi S-1000-2; finished thickness: 1.60mm +/- 10%; BGA size: 0.25mm; line width and space: 0.10/0.10 mm; surface treatment: ENIG; features: fine pitch, copper filled via technology

FeatureTechnical Specification
Number of layers 4 – 22 layers standard, 30 layers advanced
Technology highlightsMultilayer boards with a higher connection pad density than standard boards, with finer lines/spaces, smaller via holes and capture pads allowing microvias to only penetrate select layers and also be placed in surface pads.
HDI builds1+N+1, 2+N+2, 3+N+3,4+N+4, any layer in R&D
