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.

The following list is comprised of the different types of pcb laminates and the pcb materials needed starting with the most common ones. Pcb laminate may contain an inner prepreg. The designation of a laminate comes from the resin used. A basic pcb consists of a flat sheet of insulating material and a layer of copper foil laminated to the substrate chemical etching divides the copper into separate conducting lines called tracks or circuit traces pads for connections vias to pass connections between layers of copper and features such as solid conductive areas for electromagnetic shielding or other purposes.

Also common are pre preg materials fr 2 thru fr 6 cem 1 thru cem 5 and g 10. 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. The pcb lamination process begins with the selection of suitable materials. 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.

Fr 4 or fr4 is a nema grade designation for glass reinforced epoxy laminate material. Several laminate options are available to support the assembly of printed circuit boards. Pcb copper clad laminate is a substrate material for making printed circuit boards. Advanced printed circuit board laminate materials.

Among these are materials with a range of dielectric constants low dissipation factor and controlled mechanical properties. The laminate may be the pcbs core. What makes fr 4 the most commonly used laminate is how it performs across all characteristics. 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.

Pcb laminate material information. 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. Here you will find a number of different laminate materials used to fabricate printed circuit boards for advanced electronic applications. Fr 4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant self extinguishing.

For example copper clad laminate ccl which is a common pcb material and copper on one of both sides.
