However, it contained a majority of the exact wording from the military standard. Glass Transition Tg Finally, glass transition Tg is given. 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.
The resin system is what binds the structure layers together. It was released as the replacement standard for MIL-S A few of these characteristics are mentioned below.
Flexural strength can be determined with laminates of 0. There are also exotic resin systems such as polyimide and polyphenylene.
The flame retardant mechanism is usually bromine or RoHS compliant bromine, with phosphorous as a choice also. Tg was highlighted in the specification area due to the fact that many designers based their laminate choice for RoHS compliancy on the material Tg.
All resin systems 410c1 some moisture when exposed to high humidity environments. Today at Epec, the customer comes first, and everything 4101v do must be put through that filter.

Understanding its content and structure will lead designers to choose the laminate that best supports the final product requirements. This includes the reinforcement type, resin system, flame retardant mechanism, fillers, and glass transition.
IPC-4101C: Specification for Base Materials for Rigid and Multilayer Printed Boards
Thermal stress determines the thermal integrity of unclad or metallic clad laminates using short term solder exposure.
Next All posts Previous. Fillers help to reduce resin shrinkage, thus minimizing crack formation in filled areas. Quality SolutionsPrinted Circuit Boards. Moisture absorption determines 410c1 rate of absorption for the epoxy composite used in the laminate structure. A History of Innovation. Finally, glass transition Tg is given.
IPC – Base Materials, Laminates
The remainder of the slash sheet will list laminate requirements for material characteristics that are tested per IPC-TM Test Methods. The reinforcement type tends to be woven E-glass fiberglass but, it can also be cellulose paper and exotic fiberglass types such as unidirectional and aramid fiber.
There are many other factors that should be considered now, besides Tg, when selecting laminates. Summary IPC is the industry guideline for base laminates of printed circuit boards. Volume and surface resistivity determines cross-sectional and surface electrical resistance of the dielectric material under humid conditions. Resin systems tend to be a mix of epoxy types to meet the requirements of the laminate type.
With all the different slash sheets, understanding what they entail will be beneficial with selection of correct laminate properties for your specific PCB design. IPC is the industry guideline for base laminates of printed circuit boards. Join Our Mailing List. The primary epoxy will be listed, followed by the secondary, or 1401c a second secondary.

Using Exotic Resins Iipc are also exotic resin systems such as polyimide and polyphenylene. Loss tangent is a measure of how much of the electromagnetic field travelling through a dielectric is absorbed or lost in the dielectric.
Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI new product introduction process that helps our customers get to 410c1 faster, or the other 10 new projects we have in process, we must focus on building the new.
This is the structure component of the laminate. Fillers tend to be not applicable or Ioc, with a few laminate types using kaolin fillers. Written by Chris Perry Posted on January 31, at All slash sheets begin with the laminate specification. The glass transition is the temperature range in which the molecules of the resin transition from rigid and brittle to flexible and pliable.
