PCB material classification

What is PCB?A printed circuit board (PCB)mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components are generally soldered on the PCB.-Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes. The base pcb material (CCL-Copper Clad Laminate) is a composite materi...

PCB Materials Application Continue To Make Breakthroughs

To find the ideal balance between circuit board cost and performance for a given application. Let’s start at the beginning. The most common PCB fabrication material is FR-4. It is cost-effective, highly flexible, and mechanically strong with bond strengths at temperatures up to 130ºC. However, FR-4 does not work well for high-speed or high-frequency (greater than 1 GHz) applications circuit board where signal precision is critical and any signal loss has a significant impact on performance....

UV-YAG laser drilling of glass-reinforced PCB material

Background of ResearchThe miniaturization of electronic products for information and communication has led to the increase of circuit density of PCBs. This means that the holes which connect the isolated circuit layers in multilayer PCB are downsizing. CO2 and Nd:YAG laser operated at infrared wavelength of 10.6 mm and 1.06 mm are used extensively to fabricate microvias in PCB fabrication. However, the major drawback of laser drilling GFRP materials is the existence of heat-affected zone (HAZ) w...

PCB Material Types

PCBs, or Polychlorinated Biphenyls, are man-made chemicals. Their use is strictly controlled or banned in many countries because they pose a threat to both human health and the environment. Polution from various types of PCB materials is a major problem around the world because the chemicals are persistent organic pollutants, meaning that although PCB manufacture is mostly banned across the world, their previous use is still having an environmental impact today. What Are PCBs?There are more th...

Prototyping techniques: things to know before pulling the trigger

label: prototype a PCB,printed circuit board,PCB material Prototyping has become far more difficult than it was in the old days. For one thing, electronic components have gotten smaller; an IC can now be the size of a peppercorn or a grain of sand. As a result, you must take measures to illuminate, observe, and handle these tiny parts. Making things even more difficult is the fact that many modern circuits operate at high frequencies, so you can no longer just solder wires between components; y...

Selecting PCB materials for high-frequency applications

label: PCB Material,printed circuit board,PCB fabrication Choosing a circuit material for a high-frequency printed-circuit board (PCB) is generally a tradeoff, often between price and performance. But PCB materials are also selected by two key factors: how well they meet the needs of an end-use application and what kind of effort is required to fabricate a desired circuit with a particular material. These two factors may not mesh: one material may be well suited for a particular application bu...
