IPC 4101/21 - Unclad FR4

OVERVIEW
IPC 4101/21 - Unclad FR4 - See G-10/FR4 Page to Order Online.
IPC, in cooperation with DSCC, has developed an IPC specification for base materials for rigid and multilayer printed boards (IPC4101) that will effectively replace MIL-S-13949 and the IPC "L" series of specifications (L-108, L-109, L-112 and L-115). IPC4101 was released for publication in December 1997 as the replacement standard for both military and commercial purchases of laminate and prepreg. It contains much of the language used in MIL-S-13949, including the requirements in the familiar Group "A", "B", and "C" inspections.

FEATURES AND BENEFITS
Standard FR4 (IPC 4101/21) is the mainstay of the printed circuit industry. Available through a host of different manufacturers, FR4 laminate has literally become a commodity item.
