PCB materials specification updated

30 September 2009 News

IPC has released revision C of IPC-4101, ‘Specification for base materials for rigid and multilayer printed boards’. Covering the requirements for base materials used primarily in rigid and multilayer printed boards for electrical and electronic circuits, the new revision adds 11 new specification sheets to reflect the expanded offerings for current commercially available laminates and prepregs.

The new specification sheets add laminate and prepreg materials with improved or additional properties for use in one or more of the following applications: low halogen, lead-free, high-thermal performance, and high-speed/high-frequency performance.

In total, 66 individual specification sheets are contained in IPC-4101C which can be searched using keywords. The keywords allow the document’s user to easily find groups of materials with common characteristics but with enough specific properties that allow them to fine-tune their laminate and/or prepreg search.
