Tired of all those small parts? Can't figure out how to route traces to all 1,900 balls on that hot new FPGA? If 0201 passives have you running scared and the possibility of 01005 parts coming soon has you on the floor, Screaming Circuits has the answer.
Do you need PCB Assembly Services, or do you not? That is the question. Well, it's A question. Just one of many, I suppose.
One of many, but it is a question just about every electronics developer needs to answer at some point. The answer isn't always yes, nor is it always no. The answer is quite often "It depends." I work here and I don't always have a clear answer to the question. I've sent some board through our plant, and have hand built a few.
For me, it comes down to a few options:
Use Screaming Circuits PCB Assembly Services:
- Does it need to be done right?
- Is time a consideration?
- Are there too may placements for me to deal with?
- Are there more than one or two boards?
- Are the parts too small?
- Are there any BGA packaged chips?
- Will it be monotonous?
Build it myself if:
- It's a no-hurry project.
- The parts big enough.
- It be fun.
- It will be a valuable learning experience.
I can enjoy building up a board myself in the same way that someone working for a car manufacturer might rebuild cars at home as a hobby. 0805 passives aren't a problem for me to hand solder. I don't mind a small number of 0603's. I'll hand solder 0402's in a pinch. I've tried a few 0201's with poor results.
Forchips, I don't have a problem with SOIC's. I'm not bad with a TSSOP. QFN parts are a challenge, but some types have enough exposed metal on the side to solder. I really can't place BGA's, but I'm experimenting to see if I can find a way to solder small ones in my toaster oven.
With the impending advent of desktop pick and place machines, there will be a few more options, but the basic question will remain the same as it is with "build vs. buy" in any industry: "Which do I have more of, time or money?"
Let's get small!
I'm not sure who first used the term "drone", but "Robot" was first publicly used by Karel Čapek in his 1921 play "R.U.R.", or "Rossum's Universal Robots." January is not only the month the play premiered, but Karel Čapek was born on January 9, 1890. With that, Screaming Circuits is declaring January, 2015 to be Rossum's Universal Robots month!
In celebration of this momentous occasion, we've produced an exclusive "Rossum's Universal Robots month" T-Shirt. When the singularity comes, wearing this shirt will inform our new robot overlords of your support for their cause. Not that it will protect you or anything, but perhaps they will assimilate you with a bit more care.
Every customer who places an order before January 9, 2015, 5:00 PM, PST, will have the opportunity to get a Free "Rossum's Universal Robots month" T-Shirt, designed by local graphic artist, Kyle DeVore.
Look for instructions via email on how to get a free T-shirt after your next order (provided the order is placed between today and on or before January 9, 2015). If you place an order between now and then, and promptly respond to the email, you can get one for free.
But, what if you don't have anything to order? Well, you can still celebrate our impending doom at the hands of our own creations by buying the T-shirt from our page on teespring.com [Click here to buy on Teespring]. We don't want grease money, so we're selling them on teespring at our cost.
Poor Alquist ceded care of the world to Primus and Helena.
He set off on a hopeless search to find any last human survivors.
To no avail, he searched the seven continents and the seven seas.
Until at last, he saw beings, not robots, on a small island near Sumatra.
Poor Alquist, being not a newt, was never again seen on land or at sea.

The upside of a visible identity is that people see you can might possibly care and understand. The downside, is that people can find you. Today, I'm sort of treading the line between the two.
I'm testing out some Twitter ads right at the moment. As someone that has a service to present, I have to do things like that. Ideally, it won't be intrusive and will just give information, but that's not the point.
One of the steps in putting together a Twitter ad is to select categories of Twitter users that might be interested in what I do. The process of picking those categories reminded me of something that's almost always annoyed me when I have to pick my categories for anything. Namely, my categories aren't there.
This particular ad, is sending people to eBay to buy (hopefully) a coffee mug with the Sputnik 1 transmitter schematic on it. We're doing it to help out our local FREE GEEK place. (Yikes! Three links in a row) Again, that's not the point here.
I'm thinking that electrical engineers would be interested, as would space fans. Well, those categories don't really exist. The have a major category: "Business." The closest sub category in Business is "Technology." That's somewhat close, but do engineers really want to be classified as in the business world?
"Careers"; nothing close in the sub categories. "Education"; nothing close. "Events" has "Tech Tradeshows" as a sub-category, but as with business, it's not really where I'd look.
"Hobbies and Interests"? Nope. They have "Astrology", but no hobby electronics.
There's the category "Science", but its subs look like chapter headings in a sixth-grade science book.
Wait! There's "Technology and Computing"! That looks promising... But... No. It's pretty much software and IT.
And, that's it. I see this sort of thing all over the place. Software, IT and businessy stuff get categories, but electronics design, embedded computing, robotics... Other than in the direct EE press, these types of categories just don't seem to exist.
What time it is?
For those of you who don't know Nikola Tesla... Never mind. If you don't know who he is, you're probably not an actual engineer. If you are an engineer, but still don't know, I challenge you to use your powers of self-education, and spend a little time learning about the person who pretty much made the modern world possible.
Part of our homage comes in the form of a free T-shirt. Every customer who places an order before August 10, 2014, 5:00 PM, PST, will have the opportunity to get a Free "National High Voltage AC Month" T-Shirt, designed by local graphic artist, Kyle DeVore.
Look for instructions via email on how to get a free T-shirt after your next order (provided the order is placed between today and on or before August 10). If you place an order between now and then, and promptly respond to the email, you can get one for free.
But, what if you don't have anything to order? Well, you can still celebrate life threatening high voltage induction by buying a T-shirt from our page on teespring.com. (link here).
Any profits from the sale of the shirts will be donated to the Tesla Museum at Wardenclyffe.
How Teespring works: Orders can go in during a 21 day window. If you buying one, you don't get charged until the closing date. After that, they send you the shirt about a week or so after. They send any profits we made on the shirt directly to Tesla Science Center at Wardenclyffe; a 501(c)3 not-for-profit organization registered with the State of New York.
If you're a recipient of one of the free shirts, you won't pay anything. Your shirt will be mailed at about the same times as the paid shirts.
There are a lot of places suitable for running an electronics manufacturing plant. Ours is in Oregon, USA – the Silicon Rain forest, if you will. The slower pace of life here, the proximity to recreation and wilderness, the rain soaked green hills; all help to create a healthy and invigorating environment. That’s a healthy environment for those of us that work here and that helps us to deliver dedicated service and quality product on time.
Deep in the woods of Oregon - up at an elevation of about 3000 feet, tucked behind soaring trees in a remote corner of the West-central Cascade foothills lays an alluring, mystifying volcanic remnant, known as Clear Lake.
Snow melt from nearby Mt. Washington and many of its Western hillsides, plus a series of complex underground springs, fill it with extremely cold, ultra-pure water. This creates an average temperature in the lake that is so low that comparatively little algae growth, or other biological activity that would otherwise obscure entering sunlight is able to thrive. Scuba divers are drawn to the exceptionally clear waters to see, with their own eyes, the remains of the ancient forest dispersed along its bed, still preserved in frigid stasis from the time the lake was formed.
Just to stand on the shoreline and gaze into the slowly rippling turquoise-blue waters, which allow for visibility of up to of 100 feet below the surface, can create a dreamlike feeling of wonder in the observer. Don’t get too comfortable, however… because a miles-long sleeping giant who carries the secret of how the lake originally formed rests motionless, just a few miles to the East.
The Sand Mountain Volcanic Field towers another 2000 further vertical feet above Clear Lake’s shoreline, yet is just a few miles away. It is a massive alignment of 23 cinder cones, sitting dormant, interspersed with 42 distinct vents.
Around 3000 years ago, lava eruptions from vents within this volcanic field flowed downhill and blocked a river, drowning its valley. This immense flow of lava formed Clear Lake and created the relic of standing trees still visible in its depths today.
Porous volcanic rock and soils within these hillsides capture snow melt and other moisture for a gigantic naturally occurring filter. It will be an estimated 2-10 years before it reemerges at Great Spring, on the North East end of Clear Lake.
When the lake water exits over the centuries-old lava flow, the cascading deluge becomes the headwaters of the McKenzie River - and the highest permanent source of its clean, fresh water. The river then flows downhill towards the cities of Springfield and Eugene nearly 75 miles away, providing over 200,000 with their sole source of drinking water.
For 8,000 years – until the early 1800’s – peoples of the Molalla, Sahaptain, Chinook and Kalapuya tribes traveled, hunted, and lived along the McKenzie River. Very little has survived from their culture, but it’s interesting to wonder about what they contemplated when standing on the beautiful shores of Clear Lake, and as they witnessed firsthand the extraordinary events which created it.
You can find this gem for yourself, on Oregon state highway 126 (The McKenzie highway) - just two hours and 20 minutes from your pc boards being assembled at Screaming Circuits.
So, here in Oregon, USA, it's Friday the 13th - and, we have a full moon, to boot. In many societies, both of those would portend of doom. Baseball players tend to be a suspicious lot, so if you're a baseball player, you should stop reading now. Everyone else, keep going and I'll explain why there's nothing to worry about.
Well, the first reason that there's nothing to worry about, is that superstitions are really a bunch of hooey.
Beyond that, it's important to note that we speak hexadecimal here. That means it's really not Friday the 13th. It's actually Friday, the 0x0D. It won't be the true 13th until next Thursday, and there's no superstitions that I know of about Thursday, the 13th.
As far as the full moon goes... There does seem to be a certain amount of anecdotal evidence suggesting that there's more looniness when the moon is full. However, looniness isn't necessarily a bad thing. If you're an officer of the law and your job is to protect the world from 2:00 am two-beer-heroes, then most certainly, extra care must be taken.
On the other hand, in fields requiring creativity, a little looniness can actually help the cause. Tesla clearly had his looniness, and look what he did: pretty much invent the modern world. Einstein? Yeah; a good kind of loony too.
So there you go. Revel in the potential for extra creativity. Don't worry about Friday, the 13th, because it's not the 13th. And, don't worry about the full moon either, because, why worry?
I'm certainly happy I live in a split-level head
Here at Screaming CIrcuits, we're all busy making sure to get everyone's assembly orders shipped off on time so here's a picture of one of our corporate kitty cats.
We have a pair that live on campus here. They seem to be quite content to buzz about the parking lot and surrounding hedges all day while we build things. That's for the best because we do keep them off our production floor. Cats can cause static electricity and that would be bad.
Make sure the dip with your chips is lead free before eating it
This isn't a Thanksgiving blog. It is Thanksgiving day, and if it were a Thanksgiving blog, I would have to be working today, but we're shut down for the holiday, so I'm not working. I just woke up pondering what it would be like to do business with us (or anyone like us) and decided that I wanted to hear myself speak (metaphorically) for a bit. A word of warning though; I'm in a long-winded rambling mood today.
Take an example; the Beagleboard. I use that because it's a complex board that's open source, so I can freely talk about it. It was originally put together by Gerald Coley and Jason Kridner. I don't know how long they spent designing it, but according to a UBM study, a typical product design cycle is about a year.
So, what we're really talking about is a year of a couple of engineer's lives. It can be a lot of cash money too. When ordered in large quantities, the Beagleboard and it's progeny are inexpensive enough to be sold for quite a decent price. However, when purchased in small quantities - say five - it can cost several thousand dollars.
When the Beagleboard was new, we built a few just to kind of show off. We took the open source files and ordered all of the parts. We tried to get some PCBs fabbed, but in that quantity, they would have cost us $1,200. Instead, I posted a request on the Beagleboard.org forum and found someone with some bare Beagleboard fabs.
I got those boards and the parts and ran them through our system. Had a customer quoted the build, it would have cost somewhere (if my memory serves correctly) around $800 per board for assembly. That would be $10,000 for a set of prototypes. That may seem like a lot for a board that retails for $150.00, but that's the difference between ordering hundreds of thousands and ordering five.
That cost comparison isn't the point. If you're in this business you know that getting small quantities of complex stuff in short notice is expensive in direct dollars, but more than worth it in time and effort saved. The point is that, while we build a lot of sub-$1,000 orders, we are frequently given orders that are valued at $10,000 or more. Sometimes CONSIDERABLY more. We've seen projects where parts alone are tens of thousands of dollars. I've seen a single FPGA cost several thousand dollars alone. Yikes!
You've spent a year of hard labor on a design. You hit "Save" for the last time. If you're like me, you want nothing more than to get a working board into your hands. The gap between that save and a fully built board is painful for me. But the prospect of shelling out $20,000 to some unknown company for the purpose of turning that year of my life into a physical product is positively terrifying.
Well, if you don't already do business with us, we are that "some unknown company." That makes me wonder how this all happens. I design boards myself - not the big ones, but I do design a fair number of them. Right now, I have four boards I'm actively working on and about that many that I've shelved for a few months. I understand a bit of the fear of handing a design off. Of course, I have an unfair advantage. I can just send some boards through our shop and get them done just about any time.
It's easy for me to trust us. I got a job here and I know that I take the stewardship of that big check and year of your life very seriously. I treat it like it were my own. I also know that I don't work for companies that don't share that philosophy. I've tried, out of necessity, twice in my career, working for companies that didn't treat customers they way I would and I ended up pushing my agenda so hard that I got fired. It wasn't pretty.
I've established that I (as in me) trust us. How do you get to the point that you can give us (or anyone else) the same trust? The Beagleboard guys didn't know us enough to do so. We built some of their boards on our own. Plenty of people do know us well or are somehow willing to make that leap. We quite literally* have built things that have gone up into space, down into the ocean and everywhere in between. It's pretty fun to look through our customer list and see so many names of companies doing really cool stuff.
All of the marketing mumbo-jumbo I spit out is designed to somehow convince you to let us take care of your design. But those are just words. Words are meaningless without the deeds. It's what all of the other people in my company do that really counts. I spill out glurge. They do their best to treat your project with the same respect and care that you do. I'm thankful for that, because if they didn't do that, I wouldn't want to work here. If they didn't do that, my job would be meaningless and stupid. Hey - this did turn out to be a Thanksgiving post!
* The word "literally" is terribly misused these days, but I'm actually using it by the correct definition. Well, okay, the "everything in between" isn't quite literal, but "space" and "under water" are. And it's comprehensive a representative sample that I'm in the spirit of "literal."
