The use of square pad for anode vs cathode is even less standardized.
#Diptrace pads in circle software#
DipTrace is an EDA/CAD software application for creating schematic diagrams and printed circuit boards with a multi-lingual interface and tutorials (currently available in English and 21 other languages). But, every one uses some one else's DIP footprint, so it commonly never gets implemented. WikiZero zgr Ansiklopedi - Wikipedia Okumann En Kolay Yolu. Yes, on ICs, the square pad is very commonly pin 1 but not on EAGLE unless the person creating the part chooses to make it so. And example of drawing something that isn't a conductive path is: drawing a logo on the PCB. I don't think there is any consensus rule on this. Īnd, AperFunction,Conductor means, the thing will be " Copper whose function is to connect padsĪnd/or to provide shielding." So, basically, we're drawing something that will provide a conductive path between pads, or will be a conductive path that provides shielding. pretty much any shape is possible! And the AperFunctionbasically specifies why the heck we're drawing this thing.
There are two shapes available for drawing lines, but for flashing, the imagination is the limit-i.e. I got pretty tight with the whole Gerber file format, but a lot has faded, so this next explanation may not be complete:Īn Aperture is like a pen tip, for stroking, and is like a rubber stamp when flashing. Years ago I wrote a program to merge Gerber files. FileFunctionĪperFunction? Well, I have to admit I'm a bit rusty on this. But, it might make it easier for the PCB manufacturer to know what the heck is going on in your file.įileFunction is specified at: Sec 5.4.1.1. %TF.FileFunction,Copper,L2,Bot*% is saying that this file draws a Bottom layer, in Copper, and that it's Layer 2, of the PCB - but, it's still a comment, so it doesn't effect the CAM process. And, according to the gerber_file_specification, is reserved for future standardized comments. On my previous PCB, changing pad properties changes both top and bottom layers shape etc, but this project, it seems that the shaped is locked on the bottom layer. I also use DipTrace, and I took a look at one of the Gerber files, generated by DipTrace, and that command is present in my file. I have successfully created and had etched a similar PCB in DipTrace yesterday, and have followed the same rules today, but it just doesnt want to change. The Gerber Spec says that is a mandatory command. I don't see that in your code, so I'm not sure how that would be interpreted. %TF.GenerationSoftware,Novarm,DipTrace,3.2.0.1*% But what do L2 and Bot mean?īut I don't understand what this is telling me and the gerber specification that explains this section is just gibberish to me with no context. This is telling me the board type - single sided copper clad. But the best Ive been able to do so far is to hunt-and-peck, just randomly searching through all the DipTrace cap components looking. Thats cool Attachment(s): copper areas.jpg.
The other joining three common pads and going around three others. One joining two pads and filling a certain area, no pads close by. If I had other pads of different sizes then there would be additional entries in this section with different ID numbers. Back to my 4.7uF example in the OP, Im sure there are many components for a capacitor within DipTrace that have a pattern suitable for my cap with 0.5mm dia leads spaced at 5mm. So theres one thing I dont quite understand how it works in Diptrace, and I dont want to be confused or make mistakes because of that. I understand this bit because in Diptrace I made my pads circles with a diameter of 2.3mm. Move to and line to commands with x and/or y coordinates.īut what units are the coordinates in? Are they steps or are they mm or inches? Or some other measurement I am not familiar with?

I have been referring to this document but unfortunately it is not entirely helpful - too much engineering/programming gibberish and not enough basic explanation.
#Diptrace pads in circle windows#
I need to be able to process one of these files in a Windows app so I am trying to understand the format. There doesn't seem to be a more appropriate thread to park this post in so general electronics will have to do.
