Production Board is a PCB board that meets design drawings, specifications, and procurement requirements in one batch. As Received products undergo mechanical testing without conditioning. Test Board determines batch quality, Test Pattern is used for testing, and Quality Conformance Test Circuit assesses printed board quality. Visual examination of appearance and size includes detecting issues like Blister, Bulge, or Cracking. Electrical and non-electrical properties, such as Contact Resistance or Bond Strength, are also assessed. Prepreg materials and adhesive films are evaluated for parameters like Resin Flow or Tack Time.
