What Is Laminate Material In Pcb

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.

What is laminate material in pcb.

Pcb laminate material information. For example copper clad laminate ccl which is a common pcb material and copper on one of both sides. Also common are pre preg materials fr 2 thru fr 6 cem 1 thru cem 5 and g 10. 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.

In addition to supporting various components it can also achieve electrical connection or electrical insulation between them. This blog familiarizes you with the four commonly used pcb laminate materials read more. Several laminate options are available to support the assembly of printed circuit boards. Among these are materials with a range of dielectric constants low dissipation factor and controlled mechanical properties.

The laminate may be the pcbs core. The pcb lamination process begins with the selection of suitable materials. Fr 4 or fr4 is a nema grade designation for glass reinforced epoxy laminate material. Advanced printed circuit board laminate materials.

Fr 4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant self extinguishing. What makes fr 4 the most commonly used laminate is how it performs across all characteristics. Together the substrate and laminate define the basic electrical mechanical and thermal circuit board properties that when used in conjunction with an accurate board type enable you to make the best selection of pcb material for your design. 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.

Choosing the right laminate is crucial as it determines stability lower loss and optimum performance of the final assembly. Pcb copper clad laminate is a substrate material for making printed circuit boards. Here you will find a number of different laminate materials used to fabricate printed circuit boards for advanced electronic applications. As shown above the common terminology used to describe the composition of the pcb stackup can be confusing.

Pcb laminate may contain an inner prepreg.
