What is Isola material?
Isola is a global material sciences company focused on designing and manufacturing copper-clad laminates and dielectric prepregs used in multilayer PCB fabrication.
What is FR-4 made of?
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).
What is dielectric material in PCB?
PCB dielectric materials are the base of any circuit board. They provide the non-conductive substrate layer between the conducting copper layers. These materials are the surface where components are soldered to form the circuit, with traces connecting each other.
What is 370HR material?
370HR laminate and prepreg products are manufactured with a unique high performance multifunctional epoxy resin, reinforced with electrical grade (E-glass) glass fabric. This system provides improved thermal performance and low expansion rates in comparison to traditional FR-4 while retaining FR-4 processability.
What is Isola company?
Isola Group, headquartered in Chandler, Arizona, is a global material sciences company focused on designing, developing, manufacturing, and marketing copper-clad laminates and dielectric prepregs used to fabricate advanced multilayer printed circuit boards.
What is CCL PCB?
Copper Clad Laminate, abbreviated to CCL, is a type of base material of PCBs. With glass fiber or wood pulp paper as reinforcing material, a copper clad board is a type of product through lamination with copper clad on either one side or both sides of reinforcing material after being soaked in resin.
What is the difference between FR4 and FR5?
FR4 has a Tg of 130° C (266° F) and a maximum operating temperature of 110° C (230° F). Thin inner laminates for multi-layer boards are also made of this material. Like FR4, but thermally more consistent. FR5 has a Tg of 160° C (320° F) and a maximum operating temperature of 140° C (284° F).
What does FR4 stand for?
flame retardant
FR4 is a standard defined by the NEMA (National Electrical Manufacturers Association) for a glass-reinforced epoxy resin laminate. FR stands for “flame retardant” and indicates that the material is compliant with the UL94V-0 standard on plastic material flammability.
