Yes. If you want us to install it, it must go in the bill of materials. For the most part, we solder thru-hole and surface mount components on the PC boards. As pretty much everyone knows, all of those parts... Read more
I really need to get back to writing about techniques and technology, but today, it's parts again. Parts pricing, specifically. We have some tariffs coming up on parts imported from China, starting on July 6th. Specifically, a 25% tariff will... Read more
I recently participated in the Altium pod cast where I discussed the origins of Screaming Circuits, some DFM hints and a few other topics. I was discussing some of the challenges everyone is having these days in procuring components and... Read more
Have you purchased any electronics components lately? Have you tried and failed to do so lately? Allocation is the word of the day and substitutions are your friend. Many, many parts are in short supply, or unavailable with extraordinarily long... Read more
The QFN (quad flat pack, no leads) package can no longer be considered exotic. It was when I first wrote about it a decade ago, but not any more. In fact, with the wafer scale BGA, it's one of the... Read more
Our all-things-about-electronics manufacturing standards body, the IPC, specifies the proper numbering order for most components. That's a pretty nice thing that they do there, but it's not always enough to prevent layout mishaps. Case in point a line of small... Read more
There are a lot of components that require special handling. Some days, "special" requirements seem more the norm than the exception. But, every now and then, we see something that puts even those special components to shame. Not long ago,... Read more
There was a time when the Bison ran free on the plains and power components were easy to design with. Everything, with the exception of an exotic few, used either the TO-220 or TO-3 packages. Even when surface mount came... Read more
Surface mount components are carefully packaged up in strips, tubes, or trays, because they're machine assembled. The assembly robots need order and organization to properly do their job. Thu-hole parts, on the other hand, are almost always manually inserted by... Read more
Part numbers are incredibly important, but can also be incredibly annoying and confusing. Obviously, we all need them, but it would be nice if there were some semblance of a standard. Well, there are some standards, like capacitor grades and... Read more
