Rounded edges, how to make normal?

Assuming that you mean the edges of the grey pcb, easy to fix. Click on the grey pcb to select it in pcb view, then in Inspector (the window on the bottom right of the screen) int the field marked “shape”, click on the pull down menu and change “Round Rect” to “Rectangle” and you will be back to square edges. It isn’t uncommon to change something unexpected in Inspector as the screen update is a bit sensitive and tends to select something you didn’t want sometimes when changing something you did want. One of Fritzing’s quirks :slight_smile: .

Replacing Copper FIll Layer graphic

I was hoping one of our more pcb knowledgeable folks would answer, but here are some suggestions. I don’t think you can replace the copper fill graphic directly but there have been a variety of posts on getting logos on to copper. If you search in the forum for “copper graphic” one of those posts should help. If not ask here again with what problem you are having (preferably with the sketch that doesn’t work uploaded) and we will try again :slight_smile:

If this is the case then it is likely that the custom PCB has some errors. When you use a custom PCB and then use copper/ground fill it follows the outline with a 2mm inset.

Can you upload a picture of your result or a copy of your custom PCB shape or both.

Also as Peter said you can use the Logo function to import an SVG and assign it to be a copper layer. But you would then need to account for all the trace locations manually during the SVG creation.

Peter, looks very nice now. I will export some Gerber files now and send them to fab. Thank you for your assistance.

Happy to help. The boards are the acid test for how well we did :slight_smile: they will tell us for sure if the mounting hole alignment is right when the headers are inserted in the board the mounting holes on the silk (or the real holes which ever you use) should match up (and we can move them if not).

Generic ICs with oblong/rectangular pads?

hello Peter
as you noticed in the esp32 thread, the sparkfun holes are not correct.
is there a chance to support me in generating the pcb files (28pins, 18pins, 8pins) with the correct diameter?

Sure, they are easy to do, I’m guessing you want 300 mil spacing for the 8 pin probably 400mil for 18 (which are usually wider than 300 mil and 300mil and 600 mil for the 28 (giving narrow and wide). One complication is pin numbering. Various parts use various pin/pad and starting numbers but changing them is a simple matter of editing the svg and changing the designation to match the part.

Please give me some minutes, I will google the datasheets.

edit:

atmega328

E = 7,62mm --> 300 mil

Add on:
Isn’t there a possibility to adopt the “generic” IC including all possibilities (pins and width) but with the nicer pads?

Yes, but that requires a code change and currently development is broken. I’m working on fixing that, but its unclear if we can do a release as Qt (the underlying framework) currently has a problem on 32 bit Windows. For now pads that can be imported are going to be the fastest solution. I was mistaking the 18 pin for some of the old 22 pin ICs that are 400 mils. I’ll make a set of svgs for the common sizes and post them in a bit.

Yes, you can use a graphic in the copper…

Use the ‘Silkscreen Image” part,
Set it to Bottom Layer (Top layer should be okay too but, I use single layers so, that’s the example).
Can use different formats but .svg is most reliable.

Example shows a board with traces for led/resistor, an un-modified “Silkscreen Part”, with a Shape and another with a stupid Face…

Shown in Fritzing
Shown in Cuprum (pcb visualizer)
Shown in exported svg from Fritzing
(the above are in a single graphic for uploading)
Shown in CopperCam (copper side of pcb, did it before I added the Face)

Hello! Im sorry if these kind of questions are irritating but I really need your help. Is there anywhere the “ublox neo 7m 000 gps module for arduino”? Ive searched everywhere on the web but I cant find it, and I really need it for a project at school. Thank you so much in advance!

A google search for “fritzing part ublox neo 7m 000 gps module” turns up:

which I fixed up. If this isn’t what you have, if you post a link to the layout of your board I can modify this one easily enough. There seem to be several of them some with 4 pins and some with 5.

Peter, I’m preparing a small php script. I could provide generated SVG files for lit. “any” pinnumber and pinwidth. Case-Drawing and viewBox need manual correction in inkscape, but at least the pads should be fine.
php

(it seems I can’t upload svgs?)

You can, but there are sometimes problems. The forum renders the svg (rather than shows it as a file) and sometimes does it wrong. We (as I will with my collection of footprints) usually upload svgs as .fzpz and then tell people it is really an svg so rename it. I’m just doing a 24 and 40 pin 600 mil footprint and will upload a really zipped .fzp file with 4, 6, 8 , 14, 16, 20, 24 and 28 300 mil and 24, 28 and 40 600 mil footprints.

OCR A font not accepted

When I try to use the font OCRA in SVG for breadboard view I get the error
“Fritzing unterstützt derzeit nur OCRA und Droid-Schriftarten–diese haben die Schriftarten in ‘D:/daten/fritzing teile/w5500_module_breadboard.svg’ ersetzt”

->Fritzing replaced the font with another font. I’m using Windows 7/64bit and the font is OCR A Std Regular.ttf

I enclose the SVG renamed as FZPZ to be able to upload it here:

Any idea, what happend here?

Printing PCBs with Fritzing

Hi all,

first post, yay! I have to say 'm a big fan of Fritzing, it’s one of my favorite applications ever.
Thanks to the community that supported the development!

I’m designing a little RPi HAT these days, but i have very little experience in circuit design and if the Fritzing print service is suited for this.

Below is an image and the .fzz of the latest version of my circuit. Can i print this (ugly) circuit with the Fritzing PCB service and expect it to work?

Thanks,

Jo

While hopefully one of those more expert in making boards than I will also comment, there are a few problems. First you should run the design rules check (pcb view routing->Design Rules Check (DRC)) which has a number of complaints about your layout. Here is a sketch that removes all the complaints as a starting point. As noted I’d wait for the opinion of someone that does more boards than I do. In general I like as many traces as possible on the bottom of the board. Runs should be as short as possible. Corners should be at 45 degrees (not right angle) for rf reasons although that probably doesn’t matter here. In any case here is an effort that passes the DRC check.
