DC Output is typically 1V with kiloamperes. Those supplies are switching supplies paralleled with syncronized phase shifted circuits. The reason is, that puls plating power supplies for galvanizing are extremly expensive. Many manufacturers not only dislike and reject those customers, they are simple not able to etch custom multi panels. Doing so, requries close agreements with the pcb etchers representative who has to inform you about the used raw material sizes and approve used panel dimensions. Here is typical multi panel with average sizes of 0,4x0,6m what makes sense if you order your boards quantities in square meters. We frequently deal with situations like this. ![]() One of my professors had a saying: “Experience is realizing earlier that you started too late”Įven pooling service calculate setup price per design file and can use the film only once why they have average high initial prices for each board. At least a dry run should be ready long before the deadline especially if you never did such a task before.) (No matter what happens such an important task as preparing an order should never be left for the last day. To your friends, your coworkers, your professor, your sponsor, … Who ever is impacted by you starting too late. In any case the main price to pay will be to own up to the mistake(s) made. (It would be highly unethical if your educator really would let this slide by you doing him a personal favor of any kind) If it is indeed a project that is part of education then the price might be a slightly reduced number of “points” or the need to do some extra additional work. I read it as “be prepared to offer something in return for an extension / increased price tag”. I would assume that he did not want to imply that your constraints are insignificant. The answer by is consistent with his particular sense of humor. I got defensive because the content of his comment implied that my time constraints were insignificant. GerbV Portable is a viewer for Gerber RS-274X files, Excellon drill files, and CSV pick-and-place files packed as a portable app so you can do. A Free/Open Source Gerber (RS-274X) Viewer in format. It seems to also manage DCODE issues, but you should carefully check that, by Import files, Export merged, and then load merged-single file again and query a few line widths on each design.Įg I query one item by select, right mouse Display Properties to get this Object type: Lineĭo a quick test pass, of one layer, and if that look ok, take more care on the XY allocates, and do all layers.Īddit1: You will also need to import/export(merge) excellon Drill files, of courseĪddit2: I also find a download link for Windows build, GerbV 2.7.0 (Jan2019), & DXF version hereĭownload GerbV Portable for free. There is no XY import offset, so as mentioned above, you need to generate each PCB where it will finally merge to.į-274X Merge(Gerber) that saysĮxport (merge visible gerber layers) to a RS-274X (Gerber) file.Īnd that does take two+ loaded files, on 2+ layers, and create a single gerber. ![]() ( I tested using gerbv version 2.6A Compiled on at 20:44:13 Windows build I fired up GerbV and tried quick import of differing gerbers… I’m not sure you can all agree on DCODES, as those usually assign automatically/invisibly. Ie you can work around a XY offset merge, which leaves DCODES to map. If you cannot import to a specific XY, your varsity friends will have to all agree on an absolute origin for each design, and they need to export/plot in origin relative mode. ![]() You have to manage X,Y,DCODE info, and avoid any conflicts in all 3 of those. ![]() Open any Gerber file, and you may start to grasp what those could be. Merge of Gerber files has some fish-hooks. You need to pause and take some deep breaths… This doesn’t mean that I’m not listening, I’m simply trying to find a solution quickly. And yes I am panicking - I have a very serious deadline.
