PRG-MODEM Modular communication device

PCB is short for Printed Circuit Board (namely Printed Circuit Board). Also known as printed circuit board, printed circuit board, because it is produced by electronic printing technology, it is called “printed” circuit board. A printed circuit board is a substrate for assembling electronic parts. It is a printed board that forms point-to-point connections and printed components according to a predetermined design on a general substrate. The main function of the product is to make a variety of electronic components form a predetermined circuit connection, play the role of relay transmission, is the key electronic interconnection of electronic products, known as the “mother of electronic products”. PCBS are used as the substrate and key interconnect for electronic parts, and are required for any electronic equipment or product.

Two, PCB manufacturing principle

We open the keyboard of a general-purpose computer and see a soft film (flexible insulating material) printed with a silver-white (silver paste) conductive pattern and a health pattern. Because of the general screen leakage method to get this pattern, so we call this printed circuit board flexible silver printed circuit board. And we go to the computer city to see a variety of computer host boards, graphics cards, network cards, modems, sound cards and household appliances on the printed circuit board is different. The substrate used is made of paper base (usually used for single side) or glass cloth base (usually used for double side and multilayer), prepreg phenolic or epoxy resin, one or both surface layers glued to a copper sheet and then laminate and cure. This kind of circuit board covered with copper sheet plate, we call it rigid plate. To make printed circuit board, we call it rigid printed circuit board. Single-side printed circuit board we call single-side printed circuit board, double-side printed circuit board, and then through the metallization of the hole for double-side interconnection, we call it a double panel. If a double-sided for the inner layer, two single-sided for the outer layer or two double-sided for the inner layer, two single-sided for the outer layer of the printed circuit board, through the positioning system and insulating binder material alternating together and conductive graphics in accordance with the design requirements of the interconnected printed circuit board will become a four-layer, six-layer printed circuit board, also known as the multi-layer printed circuit board. There are now over 100 layers of functional printed circuit boards.
