Every circuit board that is supplied by Pure PCB is subject to a rigorous acceptance criteria based on the key criteria as laid down in IPC within IPC-A-600 Acceptability of Printed Circuit Boards.


In some cases Pure PCB has adopted controls and checks that are inside of those stated by IPC utilising Pure's experience on the key criteria that can make a real world difference to the performance and functionality of your circuit board.  Through close control of our manufacturing capability Pure PCB flow these requirements down through all aspects of the production process to ensure full compliance through to a delivered product.
Pure PCB adopt 7 key PCB acceptance criter s

No Track or Open Circuit Repairs.

Allowing repair of track defects or allowing for the repair of open circuits introduces uncontrollable risk into the production process and can have a detrimental effect on the long term reliabilirty and performance of the product leading to to in field failures; as such Pure PCB mandates that no track or open circuit repairs will be accepted at Final Quality Inspection.

The correct specification of hole plating thickness is a fundamental aspect of ensuring the correct level or reliability commensurate with your product application. Pure PCB adopts the requirement of IPC Class 3 which predominantly covers military, aerospace and medical applications as its de facto requirement across all of its products. IPC Class 3 specifies between 20-25um of Copper. The adoption of Class 3 as our de facto standard provides a more robust PCB enabling the circuit to witshtand greater thermal cycling, reducing the prospect of barrell cracking in the Via, improving reliability.
