Right Click on the Part-Go to ‘Query/ Modify’-Click on Attributes Change ONLY the Following: Enter value and Tolerance in DESCRIPTION Ex. 100-OHM 1% 1/2W Enter Tolerance in PARAMTER1 Ex. 1% Enter Tolerance in PARAMTER2 Ex. 1/2W Enter value in VALUE Ex. 100 Do not change the CASE.Changing Attributes of a Generic CapacitorChanging Attributes of a Generic Capacitor For Axial THD Caps: CAPA* For Radial/ Electrolytic THD Caps: CAPR* & CAP\SAN* (CAPR\250\100  250=P, 100=D) For Tantalum SMD Caps: CAP\TAN* (EIA3216-A, EIA3528-B, EIA6032-C, EIA7343-D/E) For SMD type Caps CAP\CER\0402 CAP\CER\0603 CAP\CER\0805 CAP\CER\1206 CAP\CER\1210 CAP\CER\1812 CAP\CER\2211 CAP\CER\2220 CAP\CER\2225 Tip: To update all the parts exist in the schematic, select ‘All Parts This Type’.Right Click on the Part-Go to ‘Query/ Modify’-Click on Attributes Change ONLY the Following: Enter value and Tolerance in DESCRIPTION Ex. 0.1 uF 10% 25V Enter Tolerance in PARAMETER1 Ex. 10% Enter value in VALUE Ex. 0.1uF Do not change the CASE.Setup Instructions to Create a BOM in SchematicSetup Instructions to Create a BOM in Schematic Go to ‘File’ then ‘Report’ in PowerLogic Click ‘Setup’ near the Bill of Materials selection In the ‘Attributes’ Tab add the following: ITM, QTY, REF-DES, DESCRIPTION, VALUE, MFR, PARTNUBMER, CASE, PCB DECAL, OTHER (SOCKET) Under ‘Format’ do the following: -click Tab in the ‘Delimiter’ box -Put ‘Bill Of Materials for %j on %d’ in the Format Options box under ‘Report Title’ -Sort by ‘DESCRIPTION’ -File Format ‘Text File’Generation of BOMGeneration of BOMThe following file will be the output from Power Logic Select All, Copy All & Paste into a Microsoft Excel SheetBOM ReviewBOM ReviewGo Over the Description and Value Columns to make sure you Correctly Changed the Attributes in the Schematic to Reflect in the BOM Go Over the CASE and PCB DECAL Columns to make sure you DID NOT change the CASEDrafting Tool Tips & UseDrafting Tool Tips & UseClick on the Drafting Tools Shortcut A Tool Bar will appear and show various tool optionsSaves drafting items (i.e. diode 2-D drawings etc…) Adds drafting items to schematic (i.e. sheets, borders, etc…)Adds text (i.e. Test Points, Pins etc…)Combine/ Un-combine 2-D lines (i.e. 2-D lines in drawings) Modifies a 2-D line Add a 2-D lineGrid StandardsGrid StandardsThe standard grid is 100mil Most of the components made in the library are created with a 100mil grid Make sure your grid is set to 100mil by going into ‘Setup’ then ‘Preferences’ and clicking on the ‘Design’ Tab Make sure the ‘Snap to Grid’ feature is checked Note* You may also check at the bottom right corner of the schematic window to see what the grid is set at Short Key Command: Type ‘G100’ for 100 milCopy/ Paste TipsCopy/ Paste TipsClick the Group selector Command Select the Circuits you wish to Copy Under Edit Click ‘Copy to File’ Name the File ‘Paste from File’ into another design or sheetKey Points to Remember: 1. When Pasting make sure that the grids are similar (Refer to previous slide for instructions on figuring out the grid) 2. When pasting into a Sheet in the same Schematic the Reference Designators will Change 3. When copying a whole sheet to a new sheet, make sure the sheet sizes are the same (i.e. A, B, C, D)PCB Layout TipsPCB Layout TipsQuick Review on Copper Pour Commands Tips on Previewing the LayersHatching the CopperHatching the CopperFollowing these instructions to view the copper pour on the PCB: Go to ‘Tools’ then ‘Pour Manager’ Click on the ‘Hatch’ Tab Select ‘Hatch All’ Click ‘Start’Command for Copper PourCommand for Copper PourTo toggle between the Copper Views type in “PO”Tips for Previewing the PCBTips for Previewing the PCBColor PaletteOn/ Off SelectorsGo to ‘Setup’ then ‘Display Colors’ Click on a color from the color palette and assign it to traces on a layer, lines, text etc… To preview the layers individually simply turn which layers you want to view On/ Off For example, you may choose to suppress the Reference Designator & Assembly Drawing Information for your ease of reviewingnullAny Questions?
