There will come a time when the pin numbering on one of your library components just isn’t right. Gates could be swapped during the design process; you’re copying a high pin count component to make a ... (See More)
Dealing with PCBs day in and day out gives us a lot of exposure to good and bad engineering drawings. It is rare that we come across engineering drawings that are complete enough to create a comprehen... (See More)
Recently, I designed a circuit board for a quadcopter.
When I design a new printed circuit board (PCB), I always ask myself a few questions before I start.
The more decisions you can make be... (See More)
Despite what you may have heard, those 40 Watt laser cutters actuallycancut out traces on your next PCB.
Since he got his laser cutter a year and a half ago, [Rich] over at Nothing Labs has been... (See More)
From what we’ve seen we’d say [Jianyi Liu] is really good at etching PCBs at home. Now you can learn from his experience. He just published a mammoth guide to fabricating your own PCBs at home. That l... (See More)
If you’ve ever made double-sided PCBs without professional equipment, you had to deal with connecting one side of the board to the other. You have a few obvious choices: 1) Rely on component leads to ... (See More)
sent in his first attempt at using a HD-DVD laser diode to expose photosensitive resist to create PC boards. We’ve been meaning to give this a shot with the ol’ Epilog laser cutter. For the test, he c... (See More)
Rhys Goodwin has been working on a system to print resist onto copper clad using an inkjet printer. This is a toner transfer alternative as it still uses toner, just not quite as you’d expect. The fir... (See More)
We think that anyone who’s done at-home PCB fabrication will appreciate the tidiness that Fran maintains throughout her etching process. She recently posted a three-part video tutorial which showcases... (See More)
