Simple Mechanism Gives Support for SMT Assembly
To fight the shakes, you can do one of two things: remove the human, or improve the human. Unable to justify a pick and place robot for the former, [Tom] opted to build a quick hand support for surface-mount work, and the results are impressive considering it’s built entirely of scrap.
It’s just a three-piece arm with standard butt hinges for joints; mounted so the hinge pins are perpendicular to the work surface and fitted with a horizontal hand rest, it constrains movement to a plane above the PCB. A hole in the hand rest for a small vacuum tip allows [Tom] to pick up a part and place it on the board — he reports that the tackiness of the solder paste is enough to remove the SMD from the tip.
Dan Maloney writes on Hackaday about Timothy Woo’s Reflowduino:
Face it — you want a reflow oven. Even the steadiest hands and best eyes only yield “meh” results with a manual iron on SMD boards, and forget about being able to scale up to production. But what controller should you use when you build your oven, and what features should it support? Don’t worry…
Dubbed the Reflowduino for obvious reasons, Timothy Woo’s Hackaday Prize entry has everything you need in a reflow oven controller, and a few things you never knew you needed.
The Apertus° open source cinema team will be running a Surface Mount Technology (SMT) workshop at Maker Faire Berlin this weekend in their AXIOM booth #121:
In the course of attending a lot of fairs and exhibitions, we’ve noticed that our cameras and components attract the attention of people from all walks of life. We’ve found that despite our reassurances, people discovering the world of Open Hardware tend to doubt their capabilities where soldering tiny components by hand is concerned.
This is why we hold Surface Mount Technology workshops – so that with a little confidence, the right tools and some initial guidance from members of our team, anyone can have great fun learning to make their own PCBs. The workshops are very popular and we have visitors designing pendants and earrings with colour LEDs and blinking patterns – which always creates a buzzing atmosphere.
apertus has shared the boards on OSH Park:
We are always surprised how much useful hacking gear is in the typical craft store. You just have to think outside the box. Need a hot air gun? Think embossing tool. A soldering iron? Check the stained glass section. Magnification gear? Sewing department. We’ve figured out that people who deal with beads use lots of fine…

FacelessTech designed this small board to act as a surface-mount edge connector:
So you want to joint two boards together, You decide to use through hole female and male 2.54 pitch headers. Normally you would use through hole than ether have a 90 degree headers or just bend them over. For years this is how I did it, I would have to make sure I made sure the holes were just the right distance from the edge of the board.
