This standard replaces GB/T 5489-1985 "Printed board drawing", compared with GB/T 5489-1985, the main technical changes are as follows. --- Clearly the scope is only suitable for hand-drawing printed board drawings and printed board assembly assembly drawings, automatic CAD design can refer to this Standard (see Chapter 1); --- Added terms and definitions (see Chapter 3); --- Increased the requirements for graphics drawing, such as the figure number, graphics layer and origin requirements (see 4.2); --- Increased the color drawing method and diagram outside the two-line outline of the conductive pattern; increase the conductive pattern drawing to indicate the wire width, the most Dimensional data requirements for small pitch, lands, ring width, margins, etc.; increase the need to consider large area conductive when drawing conductive patterns Area, balanced wire, isolation area, and spacer disk size; added the contents of the inner isolation area and isolation disk for drawing multilayer printed boards (see 4.2.4); --- Added solder mask patterns such as resist pads, apertures and pad shapes (see 4.2.5); --- Increased hole pattern, deleted the contents of holes and hole resistance (see 4.2.6); --- Added structural element graphics (see 4.2.7); --- Change the original standard marker symbol and marker symbol map to character graphics (see 4.2.8, 2.5 of the 1985 edition); --- Added printed board graphics, including single-panel, double-panel, multi-layer board, imposition map, and surface mount component diagrams on printed boards (see 4.2.9); --- Added printed board assembly graphics, including printed board assembly drawings, component and structural drawing, conductive patterns and cross-overs, etc. (see 4.2.10).
