Arlon 44N is a high resin content multifunctional (175°C) epoxy prepreg system with a proprietary micordisperse ceramic filler system. 44N is engineered for the filling of clearance holes in thin Metal cores such as 0.006" Copperinvar- Copper or via holes in sequentially laminated MLB designs. Based on Arlon's 45N, the 44N system is compatible with conventional epoxy lamination and fabrication.

Arlon 45N is a tough, high Tg (175°C by DSC) multifunctional epoxy laminate and prepreg system designed for use in a variety of higher layer count MLB's. Processeable using conventional FR-4 conditions, 45N is supplied to meet the requirements of IPC-4101/24.

45NK is a woven Kevlar® aramid fiber reinforced multifunctional epoxy laminate and prepreg system engineered to provide in-plane CTE values as low as 6 ppm/°C for compatibility with leadless alumina ceramic chip carriers (LCCC's) and other low expansion SMT devices where control of laminate expansion is critical for solder joint reliability. 45NK exceeds the requirements of IPC 4101/50 (Type AFG).

47N is a low-flow epoxy prepreg engineered for binding multilayer epoxy rigid-flex or attaching heat sinks to multilayer PCBs. An optional low lamination temperature protects components already mounted on the PCB.

49N is a low-flow epoxy prepreg engineered for bonding multilayer epoxy rigid-flex or attaching heatsinks to multilayer epoxy PCBs. With a high Tg, the prepreg can be used in high-performance or hightemperature applications compared to a standard difunctional epoxy low-flow.

51N is a non-DICY multifunctional epoxy low-flow prepreg system designed to provide high reliability through lead-free solder operations. The high decomposition temperature and high thermal stability of this material is ideal for use in complex rigid-flex fabrication and assembly operations where minimum resin flow is required.

55LM is an epoxy laminate and prepreg system, reinforced with non-woven aramid fiber, with substantially lower moisture absorption compared with conventional epoxy/aramid products, even in high-humidity environments.

55NT is an epoxy laminate and prepreg system, reinforced with a non-woven aramid substrate. This system combines compatibility with lead-free processing, using a hightemperature epoxy resin, with the low in-plane (x,y) expansion and outstanding dimensional stability of non-woven aramid reinforcement.
