Flexible and Rigid Flex PCB

Flexible and Rigid Flex PCB circuitry provides a means to integrate multiple PCB assemblies without wires, cables or connectors, replacing them with thin, light composites that integrate wiring in ultra-thin, flexible ribbons between sections. In flex Rigid PCB packaging, a flexible circuit substrate provides a backbone of wiring with rigid multi-layer circuit sections built up as modules where needed. advantages for Flexible PCB & flex Rigid PCB includes Improved Resistance to vibrations and movement, Small package size, High tensile strength, High bendiness-up to 360 degrees and suitability for harsh environments.

HDI PCB

High Density Interconnect PCB Design use latest PCB manufacturing technologies available to increase the functionality of PCBs using the same or less amount of area.HDI PCBs are characterized by high-density attributes including laser microvias, fine lines and high-performance thin materials. This increased density enables more functions per unit area. Higher technology HDI PCBs have multiple layers of copper filled stacked microvias (Advanced HDI PCBs) which creates a structure that enables even more complex interconnections.

  • 1+N+1 - PCBs contain 1 "build-up" of high-density interconnection layers.
  • i+N+i (i≥2) - PCBs contain 2 or more "build-up" of high-density interconnection layers. Microvias on different layers can be staggered or stacked.
  • Any Layer HDI - All the layers of a PCB are high density interconnection layers which allows the conductors on any layer of the PCB to be interconnected freely with copper filled stacked microvia structures ("any layer via").
  • 2/2 mil line/space with 4/8 mil laser via capture pad size.
  • Material options:High temperature FR4, Halogen – Free and High Speed (low loss).

Microvias & Stacked MicroVias

A microvia maintains a laser drilled diameter of (typically 0.006" (150μm), 0.005" (125μm), or 0.004" (100μm),which are optically aligned and require a pad diameter (typically 0.012" (300μm), 0.010" (250μm), or 0.008"(200μm), allowing additional routing density. Microvias can be via-in-pad, offset, staggered or stacked, non conductive filled and copper plated over the top or solid copper filled or plated.

Microvias add value when routing out of fine pitch BGAs such as 0.8 mm pitch devices and below. Additionally, microvias add value when routing out of a 0.5 mm pitch device where staggered microvias can be used, however, routing micro-BGAs such as 0.4 mm, 0.3 mm, or 0.25 mm pitch device, requires the use of Stacked MicroVias using an inverted pyramid routing technique
