A Few Details of Note about Solder Mask

A Few Details of Note about Solder Mask
I'm going to oversimplify this, so my apologies to our colleagues over at Sunstone Circuits, but a PC board basically has four parts: metal, substrate, solder mask and silk screen. I might simplify it even more to say that it... Read more

Good kit - bad kit for kitted assembly jobs

Well over half of the projects we build here come in as turn-key orders, meaning we buy some or all of the parts and PC boards for the job. However, plenty of folks still do kit up their parts and... Read more

Law of Conservation of Parts

Law of Conservation of Parts
Reels of parts are the way to go when you need a lot of boards built. It's just not practical to deal with a bunch of cut strips when building hundreds or thousands of boards. It's even easier to use... Read more

Single Node Nets

Single Node Nets
I've read various opinions on schematic technique regarding the illustration of nets and nodes. Some folks want to route as much as is possible with net lines and some folks think it's clearer to use a lot of node symbols... Read more

30-second Philosophy - Wait or Rev Part 2
When you sell a house, the offer they make sounds great until you realize that the big number gets a lot smaller after accounting for replacing the roof, digging out the 60-year-old heating oil tank and fixing the 80-year-old plumbing.... Read more

Tip of the Day: Again with the Standard Not Standard

Tip of the Day: Again with the Standard Not Standard
Sometimes the standards-steering-you-wrong aren't just in house, but come from Industry. Case in point the three-terminal linear regulator. Back when TO-220 packaged semiconductors were first hand chipped out of boiling lava, the LM7805 three-terminal voltage regulator established an informal standard... Read more

Tip of the Day: Keep your labels standard

Tip of the Day: Keep your labels standard
(https://xkcd.com/927) Some schematics get a single designer, start to finish, some get put together by a team working simultaneously, and some get handed from one designer to another mid-stream. Consistency and discipline are always important in the design process, but... Read more

And now, Back to Our Regularly Scheduled "Fun with LEDs" Programming

And now, Back to Our Regularly Scheduled
Fun with LEDs, from the Screaming Makers LEDs are one of our favorite subjects here in the Screaming Circuits blog. Between inconsistent marking and... Well, it's mostly about inconsistent marking. In fact (or maybe in opinion), LEDs are one of... Read more
