Why Should You Choose FR4 PCB for Your Electronic Applications?

Printed circuit boards (PCBs) have been the vital element of numerous electric circuits for a long time. Thus, many electrical engineers engaged in the manufacturing of these circuit boards know the various materials that form them. FR4 is one of the most utilized materials when producing printed circuit boards. Why is it that the material in question remains popular? The post answers this and various other aspects you may wish to know about these FR4 materials used in FR4 PCB.

A Review of FR4 Material

FR in context to FR4 stands for flame retardant and the number 4 mostly indicates the difference in the material of this class from the others. FR4 is a fiberglass epoxy laminated sheet, which appears as a very thin cloth-like sheet. FR4 also stands for the grade that is used to produce such laminated sheets. Fiberglass construction contributes to the structural characteristics of the material. The exterior fiberglass material is then coated with epoxy resin that is fire retardant. This imparts a high degree of strength and good mechanical characteristics to the material.

How is FR4 positioned in a general FR4 PCB?

FR4 is considered to be the reference base of any printed circuit board, PCB. The material is subjected to the incorporation of copper foil layers. This lamination is carried out by the use of heat as well as through the use of adhesives. The copper foil is applied to laminate the material either on one side or on both sides.

Guidelines for Choosing Appropriate FR4 Material for Your FR4 Printed Circuit Board

In FR4 technology PCB, it is crucial to apply the material in a suitable thinning to construct it. The thickness is quantized in inch-based units like thousands, inches, millimeters, and so on. When selecting material for FR4 to use in the making of your PCB, there are various factors to contemplate.

When constructing the boards when space is of primary concern, it is advisable to select a thin material that is FR4. The thin material can withstand the fine structures that are necessary for the construction of gadgets, for instance, Bluetooth products, USB connects, etc. They also apply to big projects, especially when engineers wish to create pieces that occupy less space. It is recommended not to select slightly thicker ones for PCB designs to have grooves as it is easier to cut the board or fracture the board.

The thickness of a material may be reflected in the weight of printed circuit boards, and these could also change the compatibility of the components. By this, you understand that, a thin FR4 PCB material will logically lead to lightweight boards which in any case will translate to the manufacturing of lightweight electronic products. These products are light weight and very appealing and this makes shipment possible.
