In addition to building to IPC Class 2 AND Class 3 standards, Pioneer maintains Mil (DSCC) certifications to the Mil-P-50884 and Mil-PRF-55110 specifications.

Mil-P-50884

This specification establishes the requirements for flexible printed-wiring (with or without shield (s) or stiffeners) and rigid and flexible printed-wiring combinations. The rigid and flexible printed-wiring combination is called a rigid-flex printed wiring board. In the rigid-flex application, the conductor layers that are in the flexible portion are also a layer in the rigid multilayer board.

The flexible and rigid-flex printed-wiring covered by this specification are organized in the following types and classes.

Types:

• Type 1 - Singled-sided flexible material with or without shield (s) or stiffener (one conductor layer).
  
  
• Type 2 - Double-sided flexible material with or without shield (s) or stiffener (two conductor layers) with plated-through holes.
  
  
• Type 3 - Multilayer flexible material with or without shield (s) or stiffener (more than two conductor layers) with plated-through holes.
  
  
• Type 4 - Multilayer rigid and flexible material combinations (more than two conductor layers), with plated-through holes.
  
  
• Type 5 - Bonded rigid and/or flexible material combinations (more than one conductive layer) without plated-through holes.

Classes:

• Class A - Capable of withstanding flexing during installation.
  
  
• Class B - Capable of withstanding continuous flexing for a number of cycles specified on the master drawing. (Generally not used for more than two conductor layers).
