Hi Clockmanfr, I think it would be fine when you can clean those perimeter lines up and just use one line and fill. It's correct, you can manipulate any line in Target (width, layer). You can add or move edges or you can copy and paste any pads or lines... (I marked your border and moved it to the appropriate layer - you see the yellow line in my uploaded picture) It could be possible to import a separate DXF file for holes - you have complete control over your layout... You can add holes to your design. You can add planes with copper (but editing a generated polygon plane is a pain!!! It's simpler to draw it new!). I work with Target since about six or seven years - it's a usable tool! Your scaling should be right if you chose the correct factor for import. You can choose the desired line size on the import menu. I use the German version of Target but I think I can help you if you have problems... Frank |

Thanks Frank. I now await the target Software. In the interval I will start putting together the OzControl card,.... http://www.anotherpower.com/board/index.php/topic,1116.msg11607.html?PHPSESSID=h7jd5l4edljl6k4ls18pgfj4i1#msg11607 Everything is possible, just give me time. 3 HughP's 3.7m Wind T's (14 years). 5kW PV on 3 Trackers, (10 yrs). 21kW PV AC coupled SH GTI's.

I got this so far: 
I do have the feeling though that it is working backwards as a better approach is to start from a schematic. Then when changes are made it is a lot easier to also make those changes to a PCB. If you can make this with CAD then using a dedicated schematic/PCB program should be no problem as much of the detail work is done for you. And most important, working from a schematic prevents making little mistakes that are very costly when making PCB's. With a schematic making a PCB with this amount of parts (placement is already done) will be done in about an hour. Creating the Gerber files is just a click of a button and top ,bottom, silks, drill files are generated. So if a schematic is available in any form, i think that would be so much easier. My program of choice is Diptrace which for this size is free and can be downloaded from diptrace.com. I already made the parts you used on the board so if you need some help with that then it is available. Currently i am a bit slow with responding as i don't have a internet connection at my new address. Should already be installed, so in the meantime i use my smartphone as a backup. Microblocks.

Hi Clockmanfr, A question out of left field... Why not buy the fully assembled modules from EBAY? At $175 including the controller board it doesn't sound all that bad and probably not much dearer than if you build them up by the time you got boards made etc.. Also there is a warning, that worries me a it... The modules may die after several years.... Hmm is that show some inherent weakness in the design? You will also need a hefty (read Birko) soldering iron to solder some of those joints there too.. Regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

Thanks Microblocks, Yes that board is looking good. However if Frank is correct, I only tested on the Free version and got the result, then Target software looks like I can convert my DXF files to gerber files. But I will have to change my DXF to single entity Polygram's, and play with the track sizes. Many thanks for what you have done so far, but just hold for awhile and see if I can gerber file with that Target Software, that's when it turns up.

Hi Mick PJ, PowerJack recently withdrew from sale the 48vdc 230vac 15kW power board and the matching control board, that's the ones we suggest, about $280 including dely, And we are not having that situation again. In the book I point folk at their site to buy the ready made up boards, yes its cheaper. Infact, there very hardy, but QC is questionable, and I do explain about the mods that are necessary. PJ use vastly underrated toroid's that just get mighty hot, short out and that's the end of the boards. There 8kw inverter in reality can probably take 5kW surge, but will have its inadequate fans constantly on at 2kW. Its the heat that kills everything. We use are own wind multiple toroid cores, and ensure that they can take serious amount's of power without getting hot, hence our force cooling system, and layout of the boards. Its all in the book, including the necessary 300 watt soldering iron etc. The Ozinverter is now independent of any major parts from one particular manufacture. But the Power board re-design and new components are now required to match the new 8010...36 OzControl board.

Hi Frank, Help please.......... The Target 3001 PCB Software arrived 2 days ago. I only had to tweek my CAD files before DXF conversion. Target excepted all DXF format including the silk screen.... Once in Target i examined aligned and checked, then I enlarged the single line tracks to 1.5mm wide. All single line tracks must be 1.5mm wide, but not all lines on the drawings. Question.... I could not view the GERBER file even with GC-prevue to see if my track lines are 1.5mm wide. In fact that Gerber prevue software is another whole ball game......... 
Question.... For the Gerber file does the polygons need to be filled.? There are, from bottom up..... 1. Bottom Solder pad mask...... 2. Bottom copper. ....... 3. Top Copper...... 4. Top Solder pad mask...... 5. PCB board border. ..... 6. Drill hole mask. ..... 7. Silk screen Print for the top. The silk screen is layer No 99 However Target has come up with more Gerber files than the originals. I tried using the Gerber vue you recommended, but the silk screen file.? I need to get the Gerber files into the Order and type of file the PCB manufacturer wants, could you please advise. The Gerber File Zip File that Target created is 575kb. Just to big to post here.. 
http://www.shenzhen2u.com/PCB Total cost for 20 boards is $366, so i must get this right...! I am now using Target on the OzControl Board, its clunky but okay and does the job.

Hi, you have a PM! Outline is the file with suffix .Outline: - Rename it to .GML Solder Paste Top is the file with suffix .PasteTop: - Rename it to .GTP Solder Paste Bottom is the file with suffix .PasteBot: - Rename it to .GBP Solder Mask Top is the file with suffix .StopTop: - Rename it to .GTS Solder Mask Bottom is the file with suffix .StopBot: - Rename it to .GBS Silk Screen Top is the file with suffix .99: - Rename it to .GTO Silk Screen Bottom didn't you have... Drill & Holes ist the file with suffix .Drill: - Rename it to .TXT Top Layer is the file with suffix .Top: - Rename it to .GTL Bottom Layer is is the file with suffix .Bot: - Rename it to .GBL Your layout have only top and bottom? - than you didn't have Layer2-5 The files with suffixes Apr, Info, Tool and WHL are not necessary! (I hope I didn't have a mistake in my list...) Frank |
