A fabrication class should come from the product requirement and an agreed specification, not from the assumption that a higher class automatically fixes every reliability concern.
What to examine in the layout brief
Identify the applicable document edition, acceptance requirements and supplier capabilities. Discuss how those requirements affect holes, pads, inspection and the fabrication record. Keep assembly acceptance and bare-board requirements distinct.
What belongs in the release record
Record the selected class and any additional project requirements in the purchase and fabrication documents. This note summarizes a review approach and does not reproduce standard tables or substitute for the licensed standard.
Discuss this with Circuit Edge
Send the current schematic and board revision, mechanical constraints, intended construction and the question you need resolved. Circuit Edge Technologies provides PCB layout, hardware-design support, manufacturing review and practical training from Sector 70, IMT Faridabad. A useful enquiry separates the supplied inputs from decisions that still need agreement, so the scope of the review stays clear.

Numerical limits and acceptance criteria must come from the actual component documentation, supplier agreement and applicable standards. No proprietary standard tables are reproduced.
