Set IC Dimensions

[Kenny_Lu]

Hi Everyone. I am a complete newbie to Fritzing. I have a problem regarding setting the dimensions for the customised IC I just created. So far I have set the number of pins for my part and have named them all. However, I don’t know where I can set the dimensions for it as there are no prompts in the parts editor at all. Would anyone please help me out with this problem ?

Thank you very much for your time. I appreciate it

If you want to make a totally new part you have to make all the drawings etc. You can make a custom part with Inspector or Edit.

Search the package designation, something might already be made.

One or the other of these may help you as well, although it sounds like a generic IC of the appropriate pin count and change the labels with parts editor may be all you need.

A new part creation HowTo (long! So long it is in 2 posts)

(Edit: November 2016: This is an updated (and corrected) version of the original parts creation howto. This version corrects some suggestions (mostly saving Inkscape files as optimized svg which turns out to cause other problems) with the first version and expands the section on parts testing. While there doesn’t appear to be a lot of interest in this subject I’ll make at least this update so the information is as correct as I can get it.) This is a description of how I made the Valor PM6078-00…

haha thanks so much for your responses guys. A few minutes after I had posted, I realised that length of an IC grows in proportion to the number of pins used (i.e An IC with 40 pins will be scaled longer relatively to that with only 8 pins). Therefore, generally length doesn’t have to be altered manually.

As for width, we can change it by specifying the spacing between the pins as prompted by one of the specifications (i.e 300, 600mil or so).

Thank you so much for your time guys! I have successfully customised my own IC in Fritzing.
