New PCB Prototype Materials

PCB Prototype is a modern system used for cost effective manufacturing of PCB boards, primarily a main electronic component. Various PCB material can result in different PCB quality and prices while circuit manufacturing. There are usually two types of PCB material used to construct a multilayer board. Pre-preg material is thin layers of fiberglass pre-impregnated with an adhesive, and is in sheet form, usually about .002 inches thick. Core material is similar to a very thin double sided board in that it has a dielectric material, such as epoxy fiberglass, with a copper layer deposited on each side, usually .030 thickness dielectric material with 1 ounce copper layer on each side.

FR4 for PCB Prototype

FR4 is the most common substrate used in printed circuit boards. Epoxy resin is used to bond fiberglass to copper foil in the creation of FR4. FR4 is a glass fiber epoxy laminate. 1.60mm FR4 uses 8 layers of (7628) glassfiber material. The red UL / manufacturers logo is in the middle (layer 4).

Metal Core for PCB Prototype

Metal Core is popular in LED PCB industry because of its great heat elimination. A simple single layer MCPCB consists of a metal base(usually aluminum), (non-conducting) layer, copper circuit layer, IC components and solder mask.

Polyimide for PCB Prototype -- Bendable, Not Easy to Break

Polyimide / fiberglass, which can sustain higher temperatures and is much harder than FR4. Polyimide consisting of a polyimide film and silicone adhesive designed for high temperature masking applications, including the protection of gold edge fingers and edge connectors during wave soldering and reflow soldering processes within the PCB assembly industry. It is used in electrical insulation application meeting class H requirements.

Teflon for PCB Prototype -- High Frequency

With Telfon being relatively soft in comparison to FR4, special drilling parameter are required for each PTFE / woven glass base PBC material type. PTFE / woven glass base materials are not surrounded by the myth of something exotic anymore. A secured manufacturing and defined processing to PCB's are the guarantors for it. Rapid growth of applications operating at high frequencies demands a material availability with proven performance over many years. These facts are both given with PTFE / woven glass base materials.

Arlon for PCB Prototype -- Long Lifetimes at high temperatures

Arlon materials are developed for the PCB fabrication of high performance and frequency dependent printed circuits manufacturing. Typical applications are PCB's that are subjected to high temperatures during processing, such as lead-free soldering and applications with significant lifetimes at high temperatures, such as aircraft engine instrumentation, down hole drilling, under-hood automotive controls, burn-in boards, or industrial sensors.

Isola range for PCB Prototype

Isola range is a high-performance FR-4 epoxy laminate & prepreg systems designed for advanced circuitry applications. Its low dielectric constant and low dissipation factor make it an ideal candidate for broadband circuit designs requiring faster signal speeds or improved signal integrity.
