Copper & Epoxy Filled Vias in a PC Board
#pcboard
Printed circuit boards have holes made through drilling to electrically connect various PCB layers. Manufacturers have to fill vias with different materials which are conducive or non-conductive, including copper, epoxy, etc. Via filling helps reduce air or liquid trapping, thus enhancing a PCB’s function. If anything gets trapped in the hole, it would affect the PCB assembly at a high temperature which is essential for soldering without lead.
Via Filling Through Via-In-Pad
The via-in-pad is the latest technology to fill vias, however, it is more costly than the old methods, such as through-hole. HDI boards with micro-vias work better because of their low weight and compact form factor. Such vias reduce the distance between the components, eliminating trace resistance and enhancing conductivity. The via-in-pad technology also helps deal with the BGA issues.
