What Is Laminate Material In Pcb

As shown above the common terminology used to describe the composition of the pcb stackup can be confusing.

What is laminate material in pcb.

Pcb copper clad laminate is a substrate material for making printed circuit boards. We work with top pcb laminate providers to bring you a wide range of material options such as enhanced epoxy laminates ultra low moisture materials high frequency ceramic filled laminates ul 94v 0 rated rohs compliant and more. The following list is comprised of the different types of pcb laminates and the pcb materials needed starting with the most common ones. This blog familiarizes you with the four commonly used pcb laminate materials read more.

Fr 4 or fr4 is a nema grade designation for glass reinforced epoxy laminate material. Pcb laminate material information. Several laminate options are available to support the assembly of printed circuit boards. The pcb lamination process begins with the selection of suitable materials.

For example copper clad laminate ccl which is a common pcb material and copper on one of both sides. Here you will find a number of different laminate materials used to fabricate printed circuit boards for advanced electronic applications. The designation of a laminate comes from the resin used. Advanced printed circuit board laminate materials.

In addition to supporting various components it can also achieve electrical connection or electrical insulation between them. The laminate may be the pcbs core. Fr stands for flame retardant and does not denote that the material complies with the standard ul94v 0 unless testing is performed to ul 94 vertical flame testing in. Also common are pre preg materials fr 2 thru fr 6 cem 1 thru cem 5 and g 10.

Among these are materials with a range of dielectric constants low dissipation factor and controlled mechanical properties. What makes fr 4 the most commonly used laminate is how it performs across all characteristics. Fr 4 is a composite material composed of woven fiberglass cloth with an epoxy based resin binder that is flame resistant self extinguishing this definition of fr 4 is so ubiquitous within the industry that many people involved in pcb product development have come to use fr 4 as a laminate designation in this manner. Fr 4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant self extinguishing.

Choosing the right laminate is crucial as it determines stability lower loss and optimum performance of the final assembly.
