What is HDI PCB
HDI PCB (High Density Interconnect PCBA) is a compact board designed for special users. The most significant feature of HDI is the high wiring density compared to regular pcb. HDI’s increased interconnect density allows for enhanced signal strength and increased reliability. In addition, HDI boards have better improvements for RFI, EMI, static discharge, thermal conductivity, etc.
The characteristics of HDI PCB boards:
● Micro-guided holes. Hole-forming technology for microvias with hole diameter less than 150um as well as cost, production efficiency and hole accuracy control.
● Refinement of line width and line spacing. General line width and line spacing of no more than 76.2um.
● High density of pads. The density of welded joints is greater than 50 per square centimeter.
●Thin media. Interlayer media thickness to the trend of 80um and below, and increasingly stringent requirements for thickness uniformity.
