Dynamix Technology has released enhanced versions of two of the most popular IPC documents: IPC-A-600G 'Acceptability of printed boards', and IPC-6012B 'Qualification and Performance specification for rigid printed boards'.
These documents represent the culmination of four years of revision activity and the contribution of dozens of industry volunteers.
Together, the two documents represent the core IPC documents for describing the acceptable and nonconforming conditions that are either externally or internally visible on finished Printed circuit boards (PCBs) and the frequency of end-product inspections.
According to Don Dupriest, Lockheed Martin Missiles and Fire Controls and Chair of the IPC D-30 Rigid Printed Board Committee: 'The release of IPC-6012B, together with IPC-A600G, represents an aggressive industry attempt to stay current with performance requirements of present technology'.
Revision G of IPC-A-600 incorporates more than 80 new or revised graphics and photographs.
Existing sections such as those for measles, dewetting, conductor width, etchback, foil cracks and flexible circuits have been updated.
New sections have also been created to address surface plating requirements, smear removal, wire bond pads and lifted lands prior to thermal stress.
IPC-6012 has changed significantly as well.
Advances in surface finishes and hole densities and issues involving BGA, wire bond pads and internal annular ring requirements have all been addressed.
A major addition to the document includes a performance specification 'slash' sheet for the aerospace and military avionics segment of the industry which provides common exceptions to existing IPC-6012 Class 3 performance attributes.
The documents were revised simultaneously, underscoring their close relationship.
IPC-A-600 relies on IPC-6012 for the minimum acceptability requirements for PCBs and the acceptance testing frequencies required for PCB manufacture and procurement.
IPC-6012 relies on IPC-A-600 for visual support and interpretation of those requirements.
Both documents are available in hard copy or electronic format.
