It is recommended that the locations of the mounting holes and pilot holes on the PCB be labelled as “Mįor the PCBs that are required to be fed into equipment, such as wave soldering equipment, in a specific Include the component outline on the corresponding position. For components installed horizontally (such as lying electrolytic capacitors), the silkscreen should.Silkscreen characters, polarity and direction labels must not be covered by components.Component labels, mounting holes and positioning holes must be indicated on the silkscreen clearlyĪnd should be located by the relevant features.Position on non-standard boards can use this for reference.įigure 52: Barcode recommended positioning. The recommended position of the bar code on a typical board is shown in the figure below the The barcode should be orientated horizontally or vertically on the PCB, refrain from orientating the The top and bottom sides of the PCB should also be marked with ‘T’ and ‘B’ (or similar). The font should be chosen such that it can be easily read. Indicator, anti-static label, heatsink label, etc.īoard name and version should be placed on the top side of the PCB.
#SILKSCREEN EQUIPMENT SERIAL#
The contents of the silkscreen can include PCB name, version, component serial number, polarity andĭirection label, barcode box, mounting hole location code, component footprint, board direction of travel Any silkscreen text should follow the convention of left to right, top to bottom. For high-density PCB design, the contents of the silkscreen can be chosen according to specific.Special requirements should be specified in the White should be the default silkscreen ink color.The silkscreen must not overlap with solder pads or Fiducials.Recommended spacing between silkscreen objects is h 8mil.
Designers must ensure that the silkscreenĬharacter’s height is large enough to be read by the naked eye (recommended h 50mil).
The width of the silkscreen line should be greater than 5mil.
