HDI microvia pcb


our printed circuit PCB HDI Mivrovia


MicroviaPCB layout design designs printed circuit boards, wiring and pad density than conventional PCBs, with widths and smaller traces spaces.They require advanced PCB technologies such as blind vias, buried vias and microvias. HDI PCB Mivrovia are generally more expensive than conventional PCB because of the complex accumulation process involved in manufacturing.


Pourquoi opter pour la technique Microvia ?

The PCB HDI (High Density Interconnection) and microvia technology are inseparable. The microvia technology ensures, through the smallest holes made by laser, electrical connection between the layers of a multilayer board.

As part of the miniaturization of PCBs, microvias "via-in-pad" play a decisive role. "Via in Pad" means that microvia holes are positioned directly in the solder pads. Since microvias constitute no blind holes, there is no capillary effect. The solder deposit fills the minimum hollow.


Cette méthode offre de nombreux avantages :

  • Possibilité de layout avec BGA à faible entraxe
  • Miniaturisation grâce à la technique "Via in pad"
  • Obtention à faibles coûts d'un réseau de câblage très dense
  • Technique pérenne – car les composants futurs seront de plus en plus petits
  • Fiabilité optimale
  • Réduction d'effets parasites au niveau des inductances et de la capacité
