18 DESIGN007 MAGAZINE I OCTOBER 2023 are manufactured; Table 1 presents some key differences. New IPC Standards Development e IPC TAEC recently approved the request for the formation of a new subcommit- tee (D-67) and three new task groups to cre- ate three initial standards. As their basis, these standards are derived from the existing IPC- 6012, IPC-6013, IPC-A-600, and IPC-2221 standards. IPC-6905 Qualification and Performance Specification for AME Many users of AME boards consider them to be a traditional PCB or as a component to potentially mount onto a PCB. IPC-6905 requirements are derived from the existing PCB IPC-6012 and IPC-6013 rigid, flexible, and rigid-flexible qualification and performance specifications. Requirements are removed that are not applicable for AME boards (Table 1). Requirements for potential AM-specific failure mechanisms are added, such as slice-to-slice voids and delamination. Embedded formed, packaged, and unpack- aged components, along with surface compo- nents, are typically fabricated in these struc- tures. e goal will be to reference the IPC- 6017 Embedded Standard requirements and test methods as much as possible. IPC-6911 Acceptability of AME is is an important document as it will pro- vide visual surface and cross-sectional accep- tance and rejection requirements. Its struc- ture is derived from the IPC-A-600 Accept- ability standard. e task group may poten- tially acknowledge AI inspection and real time process adjustments. As with IPC-6905, views have been removed from the IPC-A-600 standard that are not applicable for additively manufactured boards. Additional views will be included to match the new IPC-6905 require- ments. IPC-B-XX AME Coupons IPC has been using 2D Gerber file-based coupons for decades. ese are documented in IPC-2221 along with associated data files. ese coupons are based on manufactur- ing processes for horizontally routed con- ductors and vertically drilled/ablated plated holes. AME does not remove material and has Table 1: Key differences between how AME and traditional PCBs are manufactured
