Screaming Circuits: Our website and Process

PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

Counting once, counting twice...

Let's say you have two options: First, you could send in your PC boards for assembly as individuals. Second, you could send them in a panel. That's all fine and dandy. For a few, send individuals. For a bunch, panels... Read more

Is your BOM a Smart BOM?

Please be aware that there is no "B" at the end of these BOMs. Still, without the "B", you can have a smart BOM or a dumb BOM. It is important to note, however, that a dumb BOM may not... Read more

Zzzzzzzap!!! Static be Bad

Engineers these days have so many issues to worry about just in component handling alone: Do my parts need baking to get the moisture out before reflow soldering? Are my parts in stock? Are my parts real or are they... Read more

Thru-Hole Parts

Screaming Circuits uses machines to place surface mount parts; even if it's just one board. Thru-hole are a different story though. Way back in the cobweby section of the building, we do have a thru-hole part sequencing and insertion machine.... Read more

Major Major and Standard Standard

We ask for your bill of materials, Gerber and centroid files to assemble your pcbs. All of those pieces of information are necessary to properly program our machines to place your parts. That's pretty standard stuff, but did you know... Read more

Day two. Custom parts

Moving on from where I left off a few days ago... I was planning on using the PIC18F2320, but in poking around, I found that the PIC18F2321 is about $3.00 less expensive in small quantities. I'm not entirely sure why.... Read more

Rain, Rain, Go Away

It's almost June her in the Pacific Northwest. At least, that's what the calendar says. I'm not sure I beleive it at the moment. The weather is acting more like October. It's a bit warmer than January, but every bit... Read more

Done and Done.

And... Drum roll, please... It works. I put in a couple of batteries, programmed the MCU and turned it on. It works. I'm always surprised when something I design works on the first try. This being such a simple design,... Read more

My Mistake - Naturally

I received my PCBs for this project from Sunstone yesterday at about 10:10. I quickly dropped them into my box of parts and delivered it to the receiving pile-of-boxes in our shipping.receiving department. At 11:40am yesterday, I received an email... Read more

Short Cuts Don't Always Make Long Delays

The saga continues. I have my parts kit. The PCBs should be here from Sunstone tomorrow. When I placed the order on our website, I estimated that I'd have the parts and PCBs today, but I wasn't really sure. I... Read more
