DE 104i
Thin laminates and prepregs have an operative influence on the effectiveness of multilayers. Due to permanent optimization of the material components and the accordingly production technology, the DE 104i ML became a versatilely applicable base material with a glass transition temperature of 140 C. The special resin formulation shows a high thermal resistance (time to delamination @ 260 C > 60 min.) and is chemical resistant which reduces the risks of resin recession to a minimum. An excessive etch back in the drill holes is prevented, whereby a high reliability of the trough-hole plating also under cyclic stress is implied. All thin laminates
DE 104i ML corresponds to NEMA-Grade FR-4 and meets the requirements of the norm IPC-4104C, corresponding to data sheet /21, /121.
