In the spiral which you have created, the trace width is 5mils and the gap between the spirals is 12 mils, am I right ? Can you please tell me how I can specify the gap between the spirals in inkspace?<br /><br />With Regards,<br />AvinashKoopa Mandukahttps://www.blogger.com/profile/00770573817560497151noreply@blogger.comtag:blogger.com,1999:blog-7396057548824140336.post-88060708166311417782014-06-03T03:56:19.647-07:002014-06-03T03:56:19.647-07:00Hello Mr.Brown,

I wanted to design an inductor similar to the one shown in the figure of the EVM module. So the trace width is extremely small(4mil) similar to your coil. Once I design it, how can I etch it on a copper board i.e., did you do the etching yourself ?<br /><br />With Regards,<br />AvinashKoopa Mandukahttps://www.blogger.com/profile/00770573817560497151noreply@blogger.comtag:blogger.com,1999:blog-7396057548824140336.post-9100676735802262422014-06-02T08:36:01.542-07:002014-06-02T08:36:01.542-07:00I used Inkscape to design the spiral inductor, Ink...I used Inkscape to design the spiral inductor, Inkscape has a nice utility to design spirals and other odd shapes.
