HDI Green Double Sided PCB Board Fabrication Isola FR408  FR408HR

Specification:

Isola FR408 printed circuit board:

Double-sided pcb have one layer dielectric layer in the middle, both sides are traces layer. Multilayer PCB is a multilayer traces layer, a dielectric layer between each 2 layer, a dielectric layer may be made very thin layers . Multilayer circuit board having at least three conductive layers, wherein the outer surface 2layers, while the remaining one was synthesized in the insulating plate. Electrical connection between them is usually done by plated through holes in the circuit board on the implementation of the cross section

Isola FR408 is a high-performance FR-4 epoxy laminate and prepreg system designed for advanced circuitry applications.

Its low dielectric constant (Dk) and low dissipation factor (Df) make it an ideal candidate for broadband circuit designs requiring faster signal speeds or improved signal integrity. FR408 is compatible with most FR-4 processes. This feature allows the use of FR408 without adding complexity to current fabrication techniques

This is the standard laminate used in our sector of the industry. We carry stocks of all the main variants. The standard thickness used is 1.6mm, but we also stock 0.8mm, 1.0mm, 1.2mm, 2.0mm, 2.4mm, and 3.2mm. The most common copper thickness is 35 microns or 1oz square foot but 70 microns 2 oz square Ft is regularly used for higher current applications.

Its closely related to FR5 which is the old high temperature version, but has now been replaced by the more common BT Epoxy type.
