The resin system is what binds the structure layers together.

IPCC: Specification for Base Materials for Rigid and Multilayer Printed Boards

Flexural strength can be determined with laminates of 0. There are also exotic resin systems such as polyimide and polyphenylene. IPC is the industry guideline for base laminates of printed circuit boards. The remainder of the slash sheet will list laminate requirements for material characteristics that are tested per IPC-TM Test Methods.

The glass transition is the temperature range in which the molecules of the resin transition from rigid and brittle to flexible and pliable.

This includes the reinforcement type, resin system, flame retardant mechanism, fillers, and glass transition.

Whether it is developing e-commerce platforms to make it easier opc work with us, or creating a NPI new product introduction process that helps our iipc get to market faster, or the other 10 new projects we have in process, we must focus on building the new.

Volume and surface resistivity determines cross-sectional and surface electrical resistance of the dielectric material under humid conditions. Understanding its content and structure will lead designers to choose the laminate that best supports the final product requirements. This is the structure component of the laminate.

The flame retardant mechanism is usually bromine or RoHS compliant bromine, with phosphorous as a choice also. Written by Chris Perry Posted on January 31, at By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.

Fillers help to reduce resin shrinkage, thus minimizing crack formation in filled areas. A few of these characteristics are mentioned below. All slash sheets begin with the laminate specification. There are many other factors that should be considered now, besides Tg, when selecting laminates.
