Particleboard with veneer. Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.

Chipboard may refer to: Particle board, a type of engineered wood known as chipboard in some countries; See also. White-lined chipboard, a grade of paperboard;
The Austrian engineer Paul Eisler invented the printed circuit as part of a radio set while working in the UK around 1936. In 1941 a multi-layer printed circuit was used in German magnetic influence naval mines. Around 1943 the United States began to use the technology on a large scale to make proximity fuzes for use in World War II. [6]
The electric power industry began in the 19th century, which led to the development of inventions such as gramaphones, radio transmitters and receivers, and television.The vacuum tube was used for early electronic devices, before later being largely supplanted by semiconductor components as the fundamental technology of the industry.
In 1958, Jack Kilby at Texas Instruments invented the hybrid integrated circuit (hybrid IC), [1] which had external wire connections, making it difficult to mass-produce. [2] In 1959, Robert Noyce at Fairchild Semiconductor invented the monolithic integrated circuit (IC) chip. [3] [2] It was made of silicon, whereas Kilby's chip was made of ...
A sample of MDF. Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [1] MDF is generally denser than plywood.
Oriented structural straw board is an engineered board made by splitting straw and formed by adding P-MDI adhesives and then hot compressing layers of straw in specific orientations. [7] Strand board can also be made from bagasse .
It revolutionized the electronics industry, [19] [20] becoming the most widely used electronic device in the world. [21] [22] The MOSFET is the basic element in most modern electronic equipment. [23] [24] As the complexity of circuits grew, problems arose. [25] One problem was the size of the circuit. A complex circuit like a computer was ...
