Quality Assurance

VISUAL INSPECTION

The substrate material is visually inspected twice before shipping to the customer. The first inspection is for surface imperfections of the raw material at goods inward. Full details can be found in our brochure.

All allowable surface imperfections are to AQL 2.5 (Level II)

The second inspection is done after the final dimensional inspection and prior to shipping. At this stage we check for

• substrate marks
  
• edge quality
  
• blocked holes
  
• dark scribing - must be 97% clean without 2 blocked pulses being together
• cracks
• missing scribe pulses

Allowable defects, unless specified or requested under concession are zero.

INSPECTION METHODS

All substrates go through a rigorous inspection procedure starting at machine set up with a first-off inspection and a verification by a third party.
Further inspections are then carried out in-process every 2 hours followed by a final dimensional inspection prior to visual inspection and despatch.
The equipment used for inspection includes calibrated non-contact optical CMM, light boxes and microscopes.
