Quality Printed Circuit Board Materials That fix your requirements

1. For your perfect PCB, you will require some knowledge of the materials that make up a PCB. Armed with this knowledge you can decide, depending on your budget, which material would be best to suit your requirements. The circuit board foundation or the base is comprised of the substrate and the laminate. Usually the substrate is a non-conductive dielectric material that is chosen based on the dielectric constant. Laminates are used in with substrates to provide a surface material or copper foil. Laminates themselves, however, can be used as the core material in certain board constructions. For these purposes, using flex printed circuits are a good investment. There are plenty of Flex PCB Manufacturers that would be willing to get the job done on short notice. Flexible substrates are a new and upcoming material that is being used in most new printed board circuits. They are primarily made up of copper. A good Flex PCB Manufacturer will be able to provide everything mentioned below. This article will elaborate on flex a little later once you understand the basics of substrates and laminates and what they require.

2. Substrates These are the dielectric composite structures that are made up of paper or glass weave and epoxy resin. These can be supplemented by ceramics to further increase the dielectric constant. Substrates are created for meeting specific property requirements, like a higher melting point, and it also needs to be able to be customized accordingly. There are a large range of standard substrates, however, from which most of the PCB manufactured are created. Some examples of these substrates are CEM-1 through CEM-5, FR-1 through FR-6, G-10 and G11, Polytetrafluorothylene, Aluminum or insulated metal substrate, RF-35 Alumina, Polymide and the flexible substrates of Pyralux and Kapton. FR-4 is the most commonly used substrate. Laminates Laminates are those materials manufactured under pressure, and are made up of paper or cloth layers and thermoset resin. Similar to substrates, laminates are created to be customizable. Laminates preferable consist of properties like high tensile and shear strength, thermal expansion coefficient, Tg and CTE. Commonly used dielectrics are polytetrafluoroethyleneFR-1, FR-4, CEM-1 and CEM-3 and common pre-preg materials FR-2 through FR-6, CEM-1 through CEM-5 and G-10.

3. Used in conjunction, the substrate and laminate define basic electrical, thermal and mechanical circuit board properties that can be used for a specific board type, and help you make the best selection for your PCB material. Now that you know what kind of materials laminates and substrates require, you will understand why flex PCB is so useful. It provides for a higher circuit density, a higher temperature operating range, size and weight reduction, and improved impedance control and reliability! Flexible printed circuits are practically everything you could want to be able to meet your PCB requirements. It also ensures that there is less errors made during assembly, and drastically reduces time and costs for assembly. Consider using flex PCB for your new project, and uncover the benefits of efficiency and effectiveness!
