Laminate And Prepreg

370hr laminate and prepreg products are manufactured with a unique high performance multifunctional.

Laminate and prepreg. Fr4 materials high tg and high speed epoxy laminate and prepreg advanced circuit materials such as bt polyimide and cyanate ester materials for a 5g connected world. As a result the prepreg is ready to lay into the mold without the addition of any more resin. Many people only know prepreg is used to bond the copper layers of copper clad laminate ccl together with copper foils in multilayer rigid printed circuit boards pcbs but don t know prepreg is also commonly used in manufacturing flexible circuits and rigid flex board. In addition the company maintains laminate and prepreg manufacturing operations in suzhou shannxi and changshu.

P prepreg consistency resin content control on line cure monitoring redundancy with ftir melt viscosity and gelation p surface quality lay up technology. Most manufacturers describe the prepreg as the glue that holds core materials together. Prepreg is a type of base material fiberglass or fabric that has been pre impregnated or reinforced with resin typically epoxy or polyimide that is partially cured. Shengyi maintains a state of the art manufacturing facility in dongguan where it manufactures fr4 cem1 cem3 and prepreg.

High tg fr 4 laminates and prepregs 170ºc performance and processing advantages high interlayer bonding strength with optimum resin flow superior dielectric thickness control wide processing window for maximum lamination performance enhanced thermal and chemical resistance compatible with automatic optical inspection process. 370hr laminate and prepreg 370hr is a high performance 180 c glass transition temperature tg fr 4 system for multilayer printed wiring board pwb applications where maximum thermal performance and reliability are required. The prepreg material is impregnated with a resin where the resin is hardened but left uncured. For example copper clad laminate ccl which is a common pcb material and copper on one of both sides.

What is the prepreg application in pcb manufacturing. This resin system typically epoxy already includes the proper curing agent. But we also make a family of low flow materials a line of thermally conductive materials have entered the arena of lead free and green products to mention a. Pcb laminate may contain an inner prepreg.

In order for the laminate to cure it is necessary to use a combination of pressure and heat. When two cores are stacked on each side of a prepreg laminate exposing the stack to heat causes the resin to begin bonding to the adjacent layers. Laminate prepreg manufacturing.
