4.What is copper wrap?
Copper wrap is a continuous deposit of plated copper that is deposited within the barrel of the hole and extends onto the surface of the PCB (or the surface of the innerlayer core if part of a HDI structure) by a minimum of 25 um.

For class 2 demands the thickness of the surface deposit of the copper wrap is minimum 5um, but for class 3 demands this will vary dependant upon where this feature is situated within the build. Please consult our technicians for further information on class 3 demands.

5.What is a capped via hole?
A capped via is when plating is added over the via hole so that the surface is fully metalised with a minimum copper / cap plating thickness of 5um for class 2 demands, or 12um for class 3 demands.

This is reliant upon the via filling material being epoxy resin as opposed to soldermask, as the epoxy will minimise the risk of air bubbles or expansion of the fill during soldering operations.This can be categorised within IPC-4761 as type VII – filled and capped via holes. It is typically used for designs with via in pad or in BGA applications where high density features are required.
