Help Information: Box Pin Specify and position rectangular Pins for the Library Part. Pins may be defined for the abel, omponent, and older layers. PLCCs would be defined with this function, for instance. BOXPINS CANNOT EXIST ON THE

AD MASTER LAYER. The

ad Master layer exists on every layer of the PCB. SMD Placement: Note that BoxPins are defined on specific layers, unlike PadPins which will be present on every layer. You must define your SMT devices for the layers on which they will be used. If you plan a PCB with SMD devices on both the omponent and older layers, for instance, an SMD bypass capacitor in 1210 sizing would have to be defined twice and saved with two distinctive names (say, 1210C and 1210S). Size allows specifying the dimensions of the Pins and their separation. `W' is the Width of the Pin. It is the dimension which aligns with the direction arrows (right, left, down, and up). `L' is the Pin's length and `d' is the separation distance used by Repeat and Comm. There is no restriction on the values for `W', `L' and `d'; the Pins they specify may even overlap when Repeated. After the mouse is used to set an initial Pin location, invoking Repeat will lay down more Pins according to the separation `d' specified in Size and direction specified by the arrows (right, left, down, and up). Comm allows keyboard entry of an initial Pin position and the number of Pins to create in prompts on the Entry Bar. The arrows (right, left, down, and up) determine the orientation and direction in which the Pins will be laid down. If your Parts cannot be defined on the defined grid (Standard or Fine Line), the Comm function must be used. Comm has a resolution of 0.001" (0.02 mm). Help Information: Pad Pin PadPins are Device Pins which exist on all layers, unlike BoxPins which only exist on the omponent or older layers. Specify and position Pins for the Library Part. PadPins may only be defined for the

ad Master layer. PGA (Pin Grid Array) ICs would be defined with this function, for instance. Size allows specifying the Pin size and separation. `D' is the diameter of each Pin and `d' is the separation distance used by Repeat and Comm. There is no restriction on the values for `D' and `d'; the Pins they specify may even overlap when Repeated. After the mouse is used to set an initial Pin location, invoking Repeat will lay down more Pins according to the separation `d' specified in Size and the direction specified by the arrows (right, left, down, and up). Comm allows keyboard entry of an initial Pin position and the number of Pins to create in prompts on the Entry Bar. The arrows (right, left, down, and up) determine the orientation and direction in which the Pins will be laid down. If your Parts cannot be defined on the defined grid (Standard or Fine Line), the Comm function must be used. Comm has a resolution of 0.001" (0.02 mm). Help Information: Pin Number Assign Pin numbers to BoxPins and PadPins. You must be on the proper Work layer before Clicking on the Pin. A prompt will appear on the Entry Bar for PinNum (the starting pin number) and Inc (the increment between Pins), if applicable. Pins which were created with the Repeat or Comm functions will be grouped together for numbering. Clicking on any Pin in the group will highlight all the Pins. The number you specify for PinNum will be assigned to the first Pin in the group, not the Pin on which you Clicked. The increment will assign numbers to the rest of the Pins in the group but only the first and last Pins will display numbers, and only while in PinNum. You may enter a negative value for Inc, but 0 is the lowest allowed Pin Number and two Pins may not have the same number. Help Information: Bound Specify a rectangular boundary for the Library Part that will enclose the physical footprint of the Device. As the Bound is rectangular, circular or oddly shaped parts will have some extra area included. The Bound is used during Placement to check if any Devices overlap. The term `overlap' is used to mean that the Bounds of two Devices envelop the same area on the screen, but does not require that the Devices be on the same layer. Pro-Board allows Settling SMD capacitors inside the Bound of a DIP or SMD IC, for instance. The Bound does not have to surround the entire Library Part, especially any Drawing. Its purpose is to trigger the Placement prompt if two parts overlap. For example, a PCB-mount BNC jack could have a circular outline with a Bound which surrounds the pins and that section of the housing which contacts the PCB, with a Drawing of the right angle projection extending outside the bound to indicate orientation. Help Information: Line There are two modes to Lines, depending on the Work layer. On the abel layer, connected Line segments will be drawn until you either invoke Next or Exit. On the

ad Master, omponent, and older layers, a filled polygon will be constructed from the vertices you have specified when you invoke Next or Exit. You must specify at least three points for this to occur. For filled polygons, the R0-R3 options determine the sharpness of the corners formed at a vertex if the included angle is less than 90 degrees. Obtuse angles will have sharp corners. Help Information: Text Add Text strings to your PCB. Text may be placed on the

ad Master, abel, omponent, and older layers, in two sizes (Small and Medium), and in two orientations (Across and Down). As this Help Text is written, the Text functions require the Diamond 12 and 20 point fonts (standard with AmigaDOS) in the Fonts: directory. Help Information: Circle Draw unfilled Circles on the abel layer and filled Circles on the

ad Master, omponent and older layers. You may Click with the mouse or use the Comm function to specify the center and radius. Help Information: Box Draw unfilled Boxes on the abel layer, or filled Boxes on the

ad Master, omponent, or older layers. You may Click with the mouse or use the Comm function to specify the loactions of the Box's diagonals. The mouse can resolve only 25 mils or 0.63 mm (Standard mode) or 20 mils or 0.50 mm (Fine Line mode). The Comm function has a resolution of 1 mil or 0.02 mm. Help Information: Set Reference Point Specify a local origin other than the lower left corner. A useful tool for simpler measurements. The values used do not affect the final design or placement of the Library Part when it is called up in Pro-Board (that is determined by Bound). Help Information: Check Check will provide information on BoxPins and PadPins. They do not have to be numbered, yet, nor do you have to specify the Work layer before clicking on the Pin if it is a PadPin. The information provided for a PadPin will be its location (relative to the SetRef position) and diameter. If the PadPin is part of a Repeated sequence, the separation distance will be shown and the location will be that of the first Pin in the sequence. The information provided for a BoxPin will be its location (relative to the SetRef position), Width, and Length. If the BoxPin is part of a Repeated sequence, the separation distance will be shown and the location will be that of the first Pin in the sequence. Help Information: Draw Draw Boxes, Lines, Circles, and Text on the

ad Master, abel, omponent, and older side layers. The functionality of each mode can depend on the WORK layer. Help Information: Define Lib Parts Pro-Lib is the utility to create Library Parts, which are those Devices which cannot be described as a DIP (such as a Through-hole IC), SIP (such as a resistor pack), or 2-Pin (such as most capacitors and resistors). Examples of Library Parts to create would be transistors, headers, ZIP (Zigzap In-line Package used for some memory chips), PLCC (Plastic Leaded Chip Carrier), PGA (Pin Grid Array), and Surface Mount Technology capacitors and resistors. Library Parts can be defined on two grids, Standard (25 mils or 0.63 mm) and Fine Line (20 mils or 0.50 mm). Library Parts defined in either mode can be loaded on PCBs in either mode, but Library Parts defined in Fine Line will display larger than those defined under Standard mode and could cause problems. You would be advised to not intermix modes for Library Parts and PCBs. While Pro-Lib is a separate program from Pro-Board, many of its IFKs perform similar or identical functions. Those IFKs will not receive long descriptions in this Help Text.
