Guest post #8: School trip to Sony UK Tec by Lucy Bunce

Since summer 2012 the Raspberry Pi has been produced in the UK, specifically in the Sony factory in Pencoed, South Wales.  As the school I teach in (Y Pant Comprehensive) is about 4 miles away I decided to arrange a trip for the GCSE Computing class.  Richard Wilkins, Senior Manager thankfully thought this was a great idea so on 13th November we went for a tour of the facility, including the Raspberry Pi production line.

For most students this was their first visit to a high tech manufacturing facility.  Donning anti-static jackets and shoes, we had the full tour. The main Sony product manufactured in Pencoed is their range of broadcast cameras.  They have a clean room where dust particles are measured in order to produce high quality optical blocks. Sony also have a repair centre onsite and students were surprised to learn that the PSP one of them had sent back for repair would have been fixed here.

We had to wear anti-static jackets before entering the factory

Utilising the expertise, equipment and space in Pencoed, Sony also offer Contract Electronic Manufacturing – such as the Raspberry Pi.  They are now producing around 16,000 Raspberry Pis a week and employing 30 people on the production line.We followed a batch of 6 Raspberry Pis up the production line and saw how the basic boards arrive in the factory 6 to a board.

Raspberry Pi circuit boards at two different stages of production

Students saw the solder paste squeegeed onto the boards through a mask, then the high speed robotic arms attaching the smaller components from tape reels. The larger components are then fitted in a separate machine which moves at a slower pace to avoid knocking them out of position.

The first stage of the construction process – applying the solder paste to the boards using a mask

The small components are bought in on reels and stuck to the solder by a robotic arm

At this point the boards are checked to ensure they have all the correct components before being put into the oven.  This carefully controlled environment fixes the solder.  The boards are run through a second production line to repeat the process for the underside (SD card mount etc.).  As you’d expect, Raspberry Pis are tested for quality control and functionality within the factory and students were interested to see that software has been written to do some of this.  Computing is used in the manufacture of computing, something that hadn’t occurred to many of the students.

Checking the finished product – here we can see the stacked RAM and CPU chips

As well as seeing the Raspberry Pi production we also saw some of the other products built there such as LED streetlighting.  For fun Sony showed us how some of their broadcast filming and editing kit can be used – with a green-screen allowing them to try out Harry Potter’s invisibility cloak!  We also saw some short film clips using the 4K projector which are maintained in Pencoed.

Free office space at Sony has been turned into a Business Incubation Centre hosting many smaller companies and tech startups.  One of these, Wales Interactive, gave us a great talk.  Their 15 or so employees (in roles as programmers, animators, artists and musicians) have created a number of games and apps for iOS, Android and consoles entirely in house.  Many of the staff are graduates of the University of Glamorgan’s BSc in Computer Games Development .  For my students, seeing just some of the study and employment options open to them within a few miles of home if they choose to follow a career in Computing was a real eye opener.

Sony are producing 16,000 Raspberry Pis a week

We don’t currently have Raspberry Pis in school (I’ve been making sure one of the IT suites is kitted out with USB keyboards and mice, and screens with DVI inputs first – we’re pretty much there).  One of the students has a Raspberry Pi at home and all are now looking forward to getting their hands on some at school.

Quote from a student, Gareth:

“I thought it was really nice to find out finally where my Raspberry Pi was made, and to see all the technology and effort it takes to make one.

I use my Raspberry Pi for many things including watching videos on YouTube and basic web browsing and some small bits of coding. I also like the program scratch which allows me to build fun but basic games in my free time which comes free with the Raspberry Pi. If the school were to get some Raspberry Pi’s I think it would be fun to learn to code, on and to experience a different OS than the standard windows that we are used to.”

Clive – you don’t need extra screens and keyboards to use a R-Pi – just hook them up to your school network, and use a ssh client (PUTTY is the best known, and is free to download) to access them from any PC on the network – all you need to know is the IP address to which each R-Pi has been assigned. Another useful tool is WinSCP, which allows seamless file transfer between the R-Pi and PC.
This approach also has the advantage of leaving the USB ports on the R-Pi free for other purposes.

A quick note – it’s not Clive, but Lucy who wrote this post. Clive’s just the messenger!

You could also (theoretically) use xming on the Windows pc and enable X forwarding in the putty client to get the X apps displayed graphically. I’ve never quite worked put how to do a full login screen X session through xming and have been happy enough with that technique and liberal use of & to background the task.

Personally, I recommend Cygwin/X ( instead of XMing / Putty, for a variety of reasons. Yes, I’ve used PuTTY and XMing myself before. Cygwin/X is easier to set up IMHO, and gives me a more solid user experience.

Thanks Lucy – really interesting post. Good to see some photos too of the production environment as it’s something new to me.

please please please can we get an option to buy a RaspberryPi SiXpack – still connected ….

liz avatar

Problem with that is that the Pis can’t be tested when they’re still in a block of six; they have to be broken down into individuals before testing. And we can’t sell untested boards. :(

Gavin Lee avatar

You could sell it as Art to hang on the wall though! :-)

I second this.
Ask Sony to give you a cople of deffective “6pack” boards (if they have any), have all the foundation members sign them, aply a spray of protective laquer so the signatures don’t fade away then frame and eBay them.
“Made in UK” art.

Kevin avatar

+1 for this request.

I would happily decorate my wall with these six packs.

great uplifting article .. I have a 512 “uk” raspberry pi .. nice to see how it was made!

Would love to run a trip like this for our traineeship and apprenticeship learners. Are you able to share the contact of the appropriate person to talk to at the plant?

liz avatar

Can you email me, Leia? The address is on the contacts page.

Sounds better than my school trip to beamish…

Shame there was only a comment from a student, rather than a pupil from the school.

Gareth is a student at Y Pant School.

Fantastic story of an amazing journey for both the teacher and students! The student, Gareth, says it all.
The technology is here, the students are ready and willing to use it, now let’s get it into our schools!

bodgy avatar

Well we now know what the students think, what about the * pupils * who go to the school?

clive avatar

“Student” is in common use in UK to mean a learner at a secondary school. It’s a synonym of “pupil” in that sense. It hasn’t just meant a learner in tertiary education for many years. You will be relieved to know that the student (‘pupil’) in question does in fact go to the school and we would like to apologise for any semantic befuddlement.

[N.B. You may get better responses if you stay in the same thread and don’t use different names each time you post about this.]

I wonder, how much Raspis are sold till now, after I’ve read they produce 16k per week.
This sounds extremly, but is a very nice way the Raspi goes.

Nic avatar

Uh uh, Lucy, I think you’re going to need HDMI screens for your RPi lab. I hope your DVI screen collection isn’t too big yet!

clive avatar

HDMI –> DVI cables are a couple of quid and work perfectly. DVI-only monitors tend to be cheaper than those that have HDMI, so a school can buy more of them on their budget.
