Information Required for PCB Layout Checklist

Constraint DrawingBoard outline illustrating the location of all fixed component coordinates. IE: Mounting Holes, Connectors, Switches, Potentiometers, etc.Note: The CAD origin, (X=0, Y=0) should be in the lower left corner of the board.

NetlistPADS format netlist including a decal list of all the library landpatterns. The header at the top of the netlist should be: !PADS-POWERPCB-V4.0-MILS!

Data SheetsPhysical description data sheets, from the component manufacturer, of all the component decals that are not in your Libraries. Only mechanical data is required, IE: pin spacing, lead size or drill size, pin numbers & silkscreen shape dimensions.

Connector Pin AssignmentsIdentify where is pin 1, pin 2, pin 3 the last Pin etc.?

SchematicNeed schematic to debug the netlist if “one pin nets” occur or if only one pin of a two pin part is in the netlist. Schematic is also used to place components.

Part PlacementPencil sketch of suggested component placement layout of major components.

Trace Routing RulesClock, ECL or High Speed trace instructions including net names and trace widths. What needs to be hand routed and what can be autorouted.

Power PlanesPower and Ground Plane instructions including bypass capacitor fanout, BGA & QFP fanout. If there are multiple nets on the same layer, need split plane information.

Silkscreen LegendSilkscreen text identification requirements including copyright, board name, part number, revision level, connector ID’s, reference designator rotations and polarity markings.

Manufacturing InformationSpecial fabrication notes, layer construction and panel information. Special assembly notes and drawings that illustrate special assembly information.

PADS SOFTWARE DECAL LIST DEFAULTS

NOTE: To prevent a designer from editing engineering decal lists, obey the following:

1. Reference Designator Names have a 15 character limit.

2. Decal Names have a 40 character limit.

3. Illegal characters for decal names are * < > ? : . , Avoid \ / because Unix systems do not accept these characters.

4. Lower case characters are allowed but pads will convert them to upper case.

5. Decal list must be in PADS format. TANGO format Decal List is not acceptable.

6. Decal list header should be: !PADS-POWERPCB-V4.0-MILS!*PART*

7. Netlist footer should be: *END*

8. SAMPLE DECAL LIST: !PADS-POWERPCB-V4.0-MILS!*PART*U1 SO14U2 PLCC-52U4 DIP16C1 CC1206Y1 XTAL14*END*

9. File name suffix default is .ASC in PowerPCB, but .net is acceptable.

10. If a decal is not in the library put “SEE DATA SHEET” in place of the decal name. Be sure to put the reference designator on the component data sheet, especially if there is more than one Library part to build.

11. If a new decal has alphabetical pin numbers, be sure that the data sheet clearly defines the pin numbering assignments. Example: Transistors with Base, Emitter and Collector.

12. If the Decal List & the Netlist are in the same ASCII file, break them into 2 files. Always ASCII IN the Decal List first, and trouble shoot and fix the errors. Then ASCII IN the Netlist.

13. BGA row and column count limit was 45 x 45 pins in Version 3.0.



PADS SOFTWARE NETLIST DEFAULTS

NOTE: To prevent a designer from editing engineering netlists, please obey the following rules:

1. Reference Designator Names have a 15 character limit.2. Pin Names have a 7 character limit.3. Netnames have a 57 character limit. 4. Illegal characters are * < > ? : . , Lower case characters are not allowed. Avoid \ /

because Unix systems do not accept these characters.5. Please use the abbreviation rather than the full name IE: use K, not CATHODE. Use A, not

ANODE. All new library decals with special alpha pin numbers (IE: NO & NC for switches) must be clearly noted on the data sheet that will be used to create the library decal.2 & 3 pin devices with alphabetical Pin Names are as follows:

DIODES CATHODE = CANODE = A

TRANSISTORS BASE = BEMITTER = ECOLLECTOR = C

POWER FETS SOURCE = SGATE = GDRAIN = D

POTENTIOMETERS CW = 1WIPER = 2CCW = 3

CAPACITORS & POSITIVE = 1BATTERIES NEGATIVE = 2

6. PADS format netlist is preferred.7. Netlist header should be: !PADS-POWERPCB- V4.0-MILS!

*NET*8. Netlist footer should be: *END*9. SAMPLE NETLIST: !PADS-POWERPCB- V4.0-MILS!

*NET**SIG N00001U1.1 C1.1 R1.1*SIG N00002U1.2 R1.2*SIG GNDU1.7 C1.2 U2.7 C2.2*SIG VCCU1.14 U2.14 C2.1*END*

10. File name suffix must be .ASC if you are using PowerPCB.



PADS SOFTWARE REF DES RENAME LIST

1. Engineer should specify at the beginning of the design, if the reference designators are to be renamed.

2. Engineer should specify the direction of the rename.Examples: Top to Bottom, Right to Left

Left to Right, Top to Bottom

3. Engineer should specify any Reference Designators that are not to be renamed.

4. If the engineer is extremely concerned about the flow of the renaming process, a WAS/IS List should be manually generated by the creation of an ASCII text file.

EXAMPLE:

*PADS-ECO**RENPART*U12 U1U5 U2U1 U3C9 C1C6 C2*END*

NOTE: *PADS-ECO* should be located in the 1st line of the ASCII text file.

*RENPART* should be located on the 2nd line.

*END* should be at the end of the file.

installing PowerPCB. The executable Program name for WordPad is write.exe, this is the name it had in Windows 3.11. The main reason to change from Notepad to Wordpad is because Notepad does not have a replace feature. The second and probably easiest way to change this editor from Notepad to WordPad is to follow the next few steps.
