Help Information: Box Pin
Specify and position rectangular Pins for the Library Part.
Pins may be defined for the <L>abel, <C>omponent, and
<S>older layers. PLCCs would be defined with this function,
for instance. BOXPINS CANNOT EXIST ON THE <P>AD MASTER
LAYER. The <P>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
<C>omponent and <S>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 <C>omponent or <S>older
layers.
Specify and position Pins for the Library Part. PadPins may
only be defined for the <P>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 <L>abel layer, connected Line segments will be drawn
until you either invoke Next or Exit.
On the <P>ad Master, <C>omponent, and <S>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
<P>ad Master, <L>abel, <C>omponent, and <S>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 <L>abel layer and filled Circles
on the <P>ad Master, <C>omponent and <S>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 <L>abel layer, or filled Boxes on
the <P>ad Master, <C>omponent, or <S>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 <P>ad Master,
<L>abel, <C>omponent, and <S>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.
