There are several types of HDI board constructions that offer different advantages: 1. Build-Up HDI This uses a conventional PCB core (typically FR-4) with additional build-up dielectric and copper layers laminated on top to form the HDI structure. The I/O pads connect through the core layers to the build-up layers. 2. Coreless HDI As the name implies, corel...
The dielectric materials used in HDI fabrication are specialized laminates engineered to enable the fine features, withstand the demanding processing conditions required, and deliver stable electrical performance. Typical materials for HDI include: Polyimides Polyimides like HD-4000 from Hitachi or Durimide from Rogers offer thermoset polymers with excellent...
HDI PCB manufacturing methods vary depending on the HDI builds, and the common manufacturing is sequential laminating. The simplest 1+N+1 HDI PCB manufacturing is similar to multilayer PCB manufacturing. For example, a four-layer HDI PCB with a 1+2+1 structure is manufactured in this way: 1. The two inner PCB layers are manufactured and laminated, and the tw...

Below are some key design considerations for heavy copper PCBs: Layer Stacking Position thick copper layers close to the board center to minimize warpage. Do not place outer layers next to each other as it exacerbates registration issues. Rotate fiber weave direction 90° between adjacent dielectric layers for stability. Component Placement Ensure sufficient ...
