	Printed circuit board - Patent 4661654
		Printed circuits such as described are well known in the fields of electricity and electronics, serving as basic elements in the realisation of electric and electronic circuits and devices for all uses.
		This patent describes a method for producing landless plated through holes in printed circuit boards, and the process is conducted in such a manner that the diameter of the holes in the mask used for protecting the copper layer from being etched, is the same as the diameter of the hole in the board.
		The printed circuit of the invention, of the kind as defined in the introduction, is a monolayer, double layer or multilayer printed circuit comprising conductor paths on at least one of its surfaces, and through holes traversing the substrate which forms the printed circuit together with the conductor paths.

	PRINTED CIRCUIT BOARD RECYCLING (Site not responding. Last check: 2007-08-09)
		Printed circuit boards are typically manufactured by laminating dry film on clean copper foil, which is supported on a fiberglass plate matrix.
		Printed circuit boards are potentially a difficult waste material to process since they generally have no usefulness once they are removed from the electrical component in which they were installed.
		The economics of printed circuit board recycling will be determined by many factors, including the characteristics of the boards to be recycled, market value of the reclaimed components/raw materials, volume of boards being recycled, and conditions of the hazardous waste/solid waste market.

	Printed circuit board - Wikipedia, the free encyclopedia
		Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army.
		Before printed circuits (and for a while after their invention), point-to-point construction was used.
		Line art and text may be printed onto the outer surfaces of a PCB by screen printing.

	Printed Circuit Boards
		Printed circuit board manufacturing (PCBM) is a complex industry requiring numerous processing steps to produce single or multi-layer printed circuit boards.
		Although printed circuit boards may be either single-layer or multilayer, most facilities in the Bay Area are capable of producing multilayer boards.
		In a negative photoresist process, the resist covering the desired circuit traces remains soft because it was not exposed to the UV light, while the resist covering the undesired copper areas is exposed to the UV light and polymerized.

	Glossary of Printed Circuit Design and Manufacturing
		artwork—Artwork for printed circuit design is photoplotted film (or merely the Gerber files used to drive the photoplotter), NC Drill file and documentation which are all used by a board house to manufacture a bare printed circuit board.
		An integrated circuit formed upon or within a semiconductor substrate with at least one of the circuit elements formed within the substrate.
		A numeric datum sent to the control circuit of the photoplotter is either a D code or an X and/or Y dimension in inches, to the nearest thousandth.

	Printed circuit transformers - Patent 4376274
		A printed circuit transformer comprises one primary track and two secondary tracks, the three tracks being located adjacent and substantially parallel to each other with one side of one of the secondary tracks and the other secondary track being connected to a common source of potential.
		The use of double sided circuit boards is expensive because of the difficulty in registering accurately the printed tracks on each side of the board, and the provision of plated through holes adds a further large element to their cost.
		The printed conductive area also extends parallel to at least a proportion of each of the secondary tracks such that an elongate gap is defined between the printed conductive area and at least part of the length of each secondary track.
