Advanced HDI PCBs feature multiple layers of copper filled stacked microvias that enable complex interconnections. Microvias are minute laser drilled holes on a multilayer circuit board, which allow interconnections between layers. In advanced smartphones and hand-held electronic devices, these microvias cross over multiple layers. Microvias are via-in-pad, staggered, offset, stacked, copper plated over the top, plated, or solid copper filled.<\/p>\n<p align=\"justify\"><strong>Types of HDI Boards<\/strong><\/p>\n<p align=\"justify\">The HDI Boards are mainly classified into three types:<\/p>\n<div align=\"justify\">\n<ul>\n<li><strong>HDI PCB (1+N+1):<\/strong> These PCBs feature one \u201cbuild-up\u201d of high-density interconnection layers. This type of PCB provides excellent stability and mounting. Popular applications include cellphones, MP3 players, UMPC, GPS, PMP, and memory cards.<\/li>\n<li><strong>HDI PCB (2+N+2): <\/strong>These PCBs have two or more \u201cbuild-ups\u201d on high-density interconnection layers. Microvias are staggered, or stacked on different layers. This PCB has thin board capabilities. The lower Dk\/Df material allows for better signal performance. Popular applications include Personal Digital Assistant (PDA), cellphones, portable game consoles, camcorders, and Differential Scanning Calorimeter (DSC).<\/li>\n<li><strong>ELIC (Every Layer Interconnection): <\/strong>These PCBs have all high-density interconnection layers, which allow conductors to be freely interconnected with copper filled stacked microvias. These PCBs exhibit excellent electrical characteristics. Popular applications include GPU chips, CPU, memory cards, etc.<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\"><strong>Advantages of HDI Boards<\/strong><\/p>\n<p align=\"justify\">HDI PCBs are considered perfect alternatives to sequentially laminated boards, or high layer expensive standard laminates. The following advantages account for their popularity.<\/p>\n<div align=\"justify\">\n<ul>\n<li>High speed<\/li>\n<li>High frequency<\/li>\n<li>Lightweight circuits<\/li>\n<li>Small size circuits<\/li>\n<li>No mechanical shocks<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\">HDI boards are currently used for consumer and handheld electronics. They are also being considered for large board designs, and their demand will grow in the future.
