What is laminate material in pcb.

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

The following list is comprised of the different types of pcb laminates and the pcb materials needed starting with the most common ones. Here you will find a number of different laminate materials used to fabricate printed circuit boards for advanced electronic applications. 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.

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. Also common are pre preg materials fr 2 thru fr 6 cem 1 thru cem 5 and g 10. Fr 4 or fr4 is a nema grade designation for glass reinforced epoxy laminate material. 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. 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. Pcb laminate may contain an inner prepreg. The laminate may be the pcbs core.

Among these are materials with a range of dielectric constants low dissipation factor and controlled mechanical properties. Pcb laminate material information. Several laminate options are available to support the assembly of printed circuit boards. Advanced printed circuit board laminate materials.

The designation of a laminate comes from the resin used.
