IPC A-600K-2016 PDF

Full title and description

IPC A-600K — Acceptability of Printed Boards. Revision K is the illustrated handbook that defines target, acceptable and nonconforming conditions for bare printed boards (rigid, flexible and rigid‑flex). It is a four‑color, photo‑illustrated acceptance guide intended for board designers, fabricators, assemblers, inspectors and quality organizations; Revision K supersedes Revision J (May 1, 2016).

Abstract

IPC A-600 (Revision K) describes visual and measurable acceptability criteria for printed circuit boards, with photographic examples and guidance on plating, hole and via quality, dielectric removal, delamination, markings, surface finishes, microvia and via‑fill conditions, and flexible circuit issues. The document is synchronized with the acceptability/qualification requirements in related IPC performance standards (for example IPC‑6012 and IPC‑6013). Revision K expanded and updated many illustrations and added coverage of microvia contact dimensions, plating/voiding/fill behavior, and edge connector plating.

Scope

Defines acceptability criteria (visual, dimensional and observable condition examples) for bare printed boards used in electronic assemblies. The scope covers rigid, flexible and rigid‑flex printed boards and provides photographic/illustrated examples of target, acceptable and nonconforming conditions for features such as conductor pattern integrity, plating quality, hole and via condition (including microvias and via‑fills), dielectric removal (etchback, smear, wicking), delamination, marking, surface finishes (including plating for edge connectors), and features specific to flexible circuits. It serves as the industry consensus reference for inspection and acceptance of unpopulated boards and aligns to related IPC qualification/performance specifications.

Key topics and requirements

• Visual and photographic examples of target / acceptable / nonconforming board conditions (four‑color illustrations).
• Plating and surface finish acceptability, including cap plating and surface plating for edge connectors.
• Hole quality: annular ring, hole wall/barrel condition, plating folds, barrel cracks and cleanliness.
• Microvia dimensions, microvia contact criteria and related acceptability limits.
• Via fill, voiding, and filled‑via acceptability (including filled and capped holes).
• Dielectric removal issues: etchback, smear, wicking and acceptable limits.
• Delamination, laminate voids/cracks, haloing and measling — detection and acceptance guidance.
• SMT/BGA pad condition, land integrity, and features important for automated inspection and assembly.
• Flexible circuit specific conditions and acceptance criteria for flex/rigid‑flex boards.
• Classified product end‑use levels (Class 1/2/3) referenced in applying acceptability criteria where applicable.

Typical use and users

Used by PCB fabricators, quality/inspection personnel, contract manufacturers, OEM engineering and procurement teams, design engineers (for design‑for‑manufacturability checks), and training organizations. It is a day‑to‑day reference for visual inspection, incoming board acceptance, process control, nonconformance disposition and inspector/operator training. When specifying purchase requirements, users should state the IPC A‑600 revision required (for example "IPC A‑600K, Revision K, July 2020" or an earlier revision if specifically called out).

Related standards

Commonly used with or referenced by: IPC‑6012 (Qualification and Performance Specification for Rigid Printed Boards), IPC‑6013 (Qualification and Performance Specification for Flexible/Rigid‑Flexible Printed Boards), IPC‑A‑610 (Acceptability of Electronic Assemblies), IPC‑2221 / IPC‑2222 (Design standards), and other IPC manufacturing and testing documents. These documents together define design, performance and acceptability workflows for printed boards and assemblies.

FAQ

Q: What is this standard?

A: IPC A‑600 is the industry illustrated guide that defines acceptability criteria for bare printed boards (rigid, flex and rigid‑flex). Revision K is the current revision (published July 2020) and supersedes Revision J (published May 1, 2016).

Q: What does it cover?

A: It covers photographic/illustrated target, acceptable and nonconforming conditions for board features — conductor patterns, holes and vias, plating and surface finishes, dielectric removal, delamination, marking, SMT/BGA pad condition, microvias and via‑fill, and flex circuit conditions — plus guidance on applying acceptability by product class.

Q: Who typically uses it?

A: PCB fabricators, inspectors and quality personnel, contract manufacturers, OEMs (engineering and procurement), design teams for DFM checks, and training organizations use IPC A‑600 as the acceptance reference for unpopulated boards.

Q: Is it current or superseded?

A: Revision K (published July 2020) is the current revision and supersedes Revision J (May 1, 2016). If you were given a reference to "A‑600‑2016" that most likely refers to Revision J (2016) — confirm the exact revision letter/date required for procurement or compliance.

Q: Is it part of a series?

A: Yes. IPC A‑600 is part of the IPC family of board and assembly standards and is commonly used alongside IPC‑601x qualification/performance specifications and IPC‑A‑610 acceptability criteria for assembled boards. The A‑600 document is the acceptance guide specifically for bare boards within that family.

Q: What are the key keywords?

A: Acceptability, printed boards, PCB inspection, plating, vias, microvia, via fill, etchback, delamination, surface finish, flexible circuits, IPC A‑600 K/J.
