Screaming Circuits: Parts Form-factors

PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

Surface mount power component footprints

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

Suspect Thru-hole Packaging

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

How Much of that part number is important?

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

The Common Parts Library

The two most common causes of delay in small volume manufacturing here at Screaming Circuits (and presumably, others like us) are component availability, and footprint mismatches. We don't substitute parts without your approval for a number of reasons. I've written... Read more

New Super Small BLE Chip

I tend to get quite excitable when new, smaller, components come along. The smaller, the better. While, I haven't yet seen it up close and personal, I've seen the announcement and datasheet for a new SoC (System on Chip), with... Read more

Continuous Strips of Parts

Not long ago (No Need To Waste Parts), I wrote about the use of tiny cut strips here at Screaming Circuits. That's good information, but only part of the story. (When has anything ever been the whole story???). There may... Read more

No need to waste parts

We love parts on reels. Who doesn't? But reels aren't always practical - and it's not just about cost. Cost is, of course, important, but there may be other factors to consider. Say, for example, you need 20 2.2K Ohm,... Read more

Packing Parts for Personal Manufacturing

Manufacturing, especially small volume one-time-only builds (like a prototype) is hard. It's not wise for most people to actively seek out chaos, but that's what we do, and we do it wisely. That's what we've been doing since 2003. We... Read more

VTP - Very Tiny Parts

A while back, I wrote about a new ARM Cortex M0+ chip from Freescale. It's not the first M0+, but I do believe that it's the smallest. I've been checking stock off and on and finally found the smallest package... Read more

BGAs and Package on Package

Take a look at the closeup of one of our Beagleboards here on the right. That's what package on package (POP) looks like up close. The bottom chip is a Texas Instruments OMAP processor, in BGA form with 0.4mm pitch... Read more
