Ncab Group On Linkedin Pcb Printedcircuitboard Ncab Ncabgroup 25 micron nominal hole plating as per ipc class 3 this is about the ncab group standard for hole plating. learn about the benefits and the risk of not havi. Ncab’s pcb specification, require that the plating of the hole walls be 25 μm thick. this is because thicker copper produces a stronger via hole, which protects against hole wall breakage during assembly, and makes the end product better under load during operation, field errors and more. * valid only for the outer phase of a buried core which needs cap plating typically when a microvia is stacked on a buried hole. ** for design tighter than this, please consult your local ncab technical contact to review specific projects case by case. For fire industry products, two key points of the ncab group’s specification stand out as being ideal. first, there’s a minimum requirement of 25 um copper thickness in the barrel of the plated holes, which is ipc class 3 requirement.

Ncab group has a specific qualification and release process for every purchase order. this is to be sure of that through the release process, all of the spec. Download our technical specifications for different pcbs, recommendations for baking flex rigid flex pcbs and sustainability and quality documents. Recently i’ve been getting a lot of questions when we’re producing flex pcbs for customers. the questions revolve around materials and more specifically, when we have a plated through hole (pth), why we need to implement pcb button plating on these designs. so, what is it and why is it needed?. This can be categorized 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.
