Chapter 1 - GeneralAbout this Tutorial

Q. Why bother creating an AutoCAD drawing and when it would seem all the documentation could be accomplished entirely within the PADS database?

A. The purpose of the PCB database is to produce a PCB (printed circuit board). This is often at odds with the purpose of a drawing database, which is to produce a graphic document (drawing) that conveys process information. This process information is often irrelevant to, and sometimes unattainable solely within, the PCB database. AutoCAD provides the most universally accepted and versatile platform for creating composite drawings. Templates, title blocks, notes and details can be easily added and manipulated into a single, readable, print or plottable, use-specific document.

All Drawings will consist of at least a template plus some combination of artwork, notes, charts, details, and any number of other elements required to document whatever process the drawing is being created to illustrate.

The purpose of this tutorial is to demonstrate the process of generating the fabrication and assembly documentation drawings and suggest methods to help you along the way.

DefinitionsFor this tutorial, “Demoa.***” will be used as an example for the design output file names. Job

names are defined by combining the job number (for example 1234), the revision level (for example A), an additional 1 or 2 character descriptors (for example TA as in Top Assembly), and a file extention (for example .DWG as in AutoCAD drawing) – 1234ATA.DWG.

A Template is the boarder that surrounds the drawing. It also contains certain default settings for things like drawing limits, text style, etc. An integral part of the template is the Title Block which, as the name implies, provides a place for the drawing title plus other fields for documentation text. Templates come in five sizes A (8 ½ X 11), B (11 X 17), C (17 X 22) D (22 X 34), and the seldom used E (34 X 44).

Artwork is the graphic part of the drawing.

HPGL refers to Hewlett Packard Graphic Language - a standard format for communicating with printers and plotters.

DXF refers to Data Transfer File: a standard file format for exchanging computer files between different programs.

An Element is any individual line, shape or text string.

A Block is a combined group of elements that can only be modified as a whole.

Tag means to select a block, group or element for the purpose of applying a modifying command.

Attributes are definitions that can be assigned to the text elements of a block. Attributes are edited using a special “edit attribute” command instead of the “edit text” or “edit properties” commands.

PADS to AutoCAD

Fabrication Drawings usually consist of a set of 2 drawings – 1 for the instructions and another for the drill drawing. Some applications may require that these two pages be combined into a single drawing.

Sheet 1 may be considered the instruction page and usually consists of 3 drawing parts (exclusive of the template): notes, layup details and the drill chart. It may also include artwork illustrating any panelization instructions.

The Notes are a list of instructions to the fabricator explaining, among other things: materials to be used, standards or exceptions to be observed, special processes required, and a general or specific description of the PCB to be manufactured.

The Layup Detail shows, graphically, a cross section of PCB.The Drill Chart lists all drill sizes required, their quantity, tolerance, and plating options. The

drill chart refers specifically to the drill drawing by the use of graphic symbols, which appear in both the drill chart and drill drawing.

Sheet 2 may be considered the Drill Drawing. It consists of a graphic top view of the PCB with symbols for the various drill sizes placed in their respective locations plus key locating dimensions referenced to both a vertical and horizontal PCB edge.

Assembly Drawings usually consists of 1 or 2 pages, depending on whether there are components installed on 1 or 2 sides of the PCB, but may have both top and bottom views on the same page if space permits. The purpose of the assembly drawing is to show the location and orientation of all components, installed or not, and provide instruction notes pertinent to the assembly process. These notes may include (but aren’t limited to) instructions for installing mounting hardware, cleaning, standards to be applied, or to call attention to unusual or special assembly processes.

AutoCAD hintsWhen selecting a template size for your drawing remember that your goal should be to have all

your artwork fitting comfortably and readably within the drawing area of the template. Sometimes there will be a policy in place for determining templates to use (for instance all fabrication drawings may be required to be on a size D template). If this is the case all the various elements of the drawing must be scaled (or not) to fit within the template. When it is strictly a matter of choice - use the following rule of thumb to determine a suitable template size (until experience shows you a better way):

If you have to scale any element up more than 3 times to fit in the drawing area go to a smaller template size if you can. If you have to scale any element down more than 3 times go to a bigger template size if you can. Remember, you can always scale the final print to fit any page size.Caution: When working with 1:1 scale drawings that contain objects, which have been dimensioned using AutoCAD, the template and other non-scale-critical elements should be scaled to fit the dimensioned objects. Doing otherwise risks scaling the dimensions along with the object. All this scaling is ultimately reconciled in the print/plot process by “fitting” the print to the media. For this reason, the “scale” field of most templates should be “none”

When using the cursor to form a box enclosing, or tagging a group of drawing elements (as you might do for a group move, mirror, copy, etc.) if you drag the cursor from right to left the group will include any elements enclosed or touched by the box. If you drag the cursor from left to right the group will include only those elements enclosed within the box.

If you’ve tagged a group but want to deselect a subgroup or individual elements, type <r> <return> and then tag or group-select the elements to remove. To add more elements (after removing some) type <a> <return> and tag or group-select the elements to add.

To re-select the previous group, initiate the command (move, copy, etc.) then type <p> <return>. The previous selection will be highlighted. Note that you can still add or remove additional elements.

To create special characters for degrees, diameter, and +/- use the string %%d, %%c and %%p respectively in your line of type:

45 = 45%%d; .125 = %%c.125; .050 .003 = .050 %%p.003.

(Almost) never explode blocks containing attributes.

The function key F8 toggles the ability the move objects a.) at right angles either vertically or horizontally, or b.) at any angle.

The function key F9 toggles the ability to snap to a grid.

Appendix

Load the ISDC AutoCAD Tools from the ISDC CD-ROM or the ISDC 3½” Master Diskette. The following is an example of the directory structure for AutoCAD R14 after the ISDC AutoCAD Tools have been installed:C:\Program Files\AutoCAD R14\Drawings\Fab_Notes = Fabrication and Assembly notes.C:\Program Files\AutoCAD R14\Drawings\Drill_Charts = All the different Drill Charts.C:\Program Files\AutoCAD R14\Drawings\Layup_Details = All the different Lay-up DetailsC:\Program Files\AutoCAD R14\Drawings\Title_Blocks = B, C & D size Drawing FormatsC:\Program Files\AutoCAD R14\Drawings\Drafting_Details = Drafting details for edge connector

Note: When using ISDC’s automated START.PCB and START.CAM files, use assigned ISDC part number for all database names. The letter after the jobname is used to represent the revision level. After the revision level, alphanumeric characters represent the description of the plot. Example L1 = Layer 1, TM = Top Mask, TS = Top Silk. After those letters and a period, three more characters are used to represent the type of file. For example JobnameATA.PE1 would be the first revision (A) of the printed circuit board “Jobname”, TA would represent the plot description “Top Assembly”, the .PE1 extension would represent HPGL plot language. In the following examples Jobname will be used as the design filename.

Example: C:\PADSPWR\CAM\Jobname> JobnameTA.PE1 = Top Assembly for CPU Board

JobnameBA.PE1 = Bottom AssemblyJobnameDD.PE1 = Drill Drawing

HP2DXF*

This is a windows program used to convert a HPGL file into a .DXF file.To use the program, double-click the HP2DXF icon on desktop. Select file/open, then browse for file you wish to translate. Then select translate button. For example:This will produce a file called JobnameTA.DXF in the C:\PADSPWR\CAM\Jobname> directory.

AutoCAD Keyboard Command Usage for ACAD Versions 10-14:

DXFIN (command line only)This is used to bring the .DXF file created by the HP2DXF program into AutoCAD. For Drill Drawing File/Save-as DD.DWG, for Top Assembly, File/Save-as TA.DWG or BA.DWG for Bottom Assembly. These will be stored in the Jobname directory:

Example for AutoCAD R14: C:\Program Files\AutoCAD R14\Drawings\Jobname>


PADS to AutoCAD

ATTDIA (command line only)This is used prior to using the DDINSERT command to set whether the attribute questions will be asked at the command line or whether the questions will appear in an editable dialog box. Example:ATTDIA 1 = blocks entered with attributes will have a dialog box.ATTDIA 0 = blocks entered with attributes will have questions on the command line.

To allow the ATTDIA system variable to always be on:a. Open the AutoCAD PROTO drawing. IE: ACAD.DWG.b. Type the AutoCAD system variable ATTDIA 1 and press ENTER.c. Save the file ACAD.DWG.

LIMITSThis is used to set the working/plotting/printing window. The following is a list of some Standard Limits:11.00,8.50 = A Size, 17.00,11.00 = B Size, 22.00,17.00 = C Size, 34.00,22.00 = D size Example: LIMITS <CR> ON/OFF/<LOWER LEFT CORNER <0.0000,0.0000>: you enter a <CR> and the system will then prompt you with UPPER RIGHT CORNER: and you enter one of the above numbers, XX,XX <CR>.

DDATTE or EDIT ATTRIBUTE (Attribute)

This is used to edit the Title Block Text or any attributes belonging to a block.Example: Type DDATTE <CR> or use the DDATTE icon, then select any feature on the Title Block and a Chart will appear in the center of the screen with all the Text Contents of the Title Block. Revise any text column and select OK and the chart will disappear and all your changes will be made.

DDINSERT or INSERT BLOCK (External References)

This is used to insert ISDC drafting aids such as:6. B, C or D Size Drawing Format with Text Properties built into the Title Block.7. Layer quantity Lay-up Details.8. Drill Charts.9. Fabrication Notes10. Assembly and Drill drawing images, DD.DWG, TA.DWG or BA.DWG created in DXFIN.

Example: Type DDINSERT <CR> or use the DDINSERT icon and a dialog box will appear. Select FILE. Then go to the correct directory of the object that you wish to insert into your drawing. Select the name of the object using a double click. Then select the OK button.

SCALE (Modify)

This is used to increase or decrease the size of an object.Example: Type SCALE <CR> or use the SCALE icon select the object, if it is not exploded, or click a window around the object if it is exploded, then <CR> and the system will prompt you with SCALE FACTOR: and you enter the ratio. Examples: 2:1 = twice scale, 3:1 = 3 times original size, 3:2 = 1½ size.

DDEDIT or EDIT TEXT (Modify)

This is used to Edit Text of exploded objects.Example: DDEDIT <CR> then select any part of the Text String that you wish to edit and an editing dialog box will appear in the middle of your screen with the Text you selected inside. Edit the text to your requirements and select OK when completed. You can type up to 80 characters in a single string.

EXPLODE (Modify)

This is used to change a Block into individual pieces. Explode is typically used to edit drawing details that are brought in using the DDINSERT command. This would be used to delete unwanted pieces of a drawing detail or to edit the text.

Example: EXPLODE <CR> then select any part of the graphic image and <CR> to finish.

MOVE (Modify)

This is used to relocate objects inside your Drawing Format. Note: F8 is the Toggle for Ortho On/OffExample: Type MOVE <CR> or use MOVE icon and select the object or objects that you want to move. Select the object with a window or a click. After you are done selecting your objects <CR> and the system will prompt you with a POINT OF DISPLACEMENT, which means select a point in which you want to start the move process. The system will prompt you with SECOND POINT OF DISPLACEMENT: Then select a point where you wish to locate the object.

MIRROR (Modify)

This is used primarily for Bottom Side Assembly Drawings.Example: Type MIRROR <CR> or use MIRROR icon and select the object, if it is not exploded, or click a window around the object if it is exploded, then <CR>. The system will prompt you with FIRST POINT OF MIRROR LINE: select a point in the middle of the object. The system will prompt you SECOND POINT: then select a point directly below and in line with the first selected point. Then the system will prompt you DELETE OLD OBJECTS? <N>: Type Y to remove the original version.

COPY (Modify)

This command is used primarily to expand the drill chart when a revision adds new hole sizes.Note: F8 is the Toggle for Ortho On/Off (you want to have “Ortho On” to move new object)

Example: Type COPY <CR> or use COPY icon and click a window around a block in the Drill Chart that contains a drill symbol and text. Then select additional graphic items that you want, but the window did not highlight and <CR>. The system will prompt you BASE POINT OR DISPLACEMENT>/MULTIPLE: and you select anywhere inside the selected objects. The system prompts you with SECOND POINT OF DISPLACEMENT: and you move the cursor down and click to locate the copied lines and text.

TRIM (Modify)

This command is used primarily on Top Assembly Drawings to remove a section of a board outline where a connector hangs over it.Note: Use the ZOOM WINDOW command to blow up the connector that hangs over the board edge.Note: You must first EXPLODE the Assembly Picture that you are trimming.

Example: Type TRIM <CR> or use the TRIM icon. The system will prompt you with SELECT OBJECTS: You select each of the connector lines that hang over the board edge and <CR>. The system will prompt you SELECT THE OBJECT TO TRIM>/Project/Edge/Undo. You now select the board outline edge that is between the two connector edges and <CR> when finished.

ERASE (Modify)

This command is used to delete unwanted items – lines, text, blocks, etc. Items to be erased can be either individually tagged using the cursor, or by rectangular areas defined by dragging the cursor.

ZOOM WINDOW (Standard)

This is used for getting up close to your work and then moves back out to see the entire picture. Example of some Zooms: Z <CR> W <CR> = Zoom Window, Z <CR> A <CR> = Zoom AllSample: All/Center/Dynamic/Extents/Left/Previous/Vmax/Window/<scale(X/XP)>:<CR

PLOT or PRINT (Standard)

This command is used to generate a HPGL pen plot file or to print the sheet on your printer.Note: If you e-mail or modem your fabrication data to your manufacturer, it is recommended that you include a 1:1 Scale HPGL plot file of the Drill Drawing ( XXXXXDD.PLT file)

Example: Type PLOT <CR>, select File/Print, or use PRINT icon. The system will bring up a PLOT dialog box. If you would like to see exactly what will be plotted or printed, select the PREVIEW FULL button. If only part of the drawing image is visible or the drawing looks zoomed out, then you need to reset the LIMITS of your drawing. If the entire image is visible, then select END PREVIEW then select OK.Note: It is assumed that you have selected all of your available options before selecting OK.
