You must be very patient and careful to place SMD at their location using a simple clamp. A magnifying glass is also essential for some (this is my case). During my browsing on the Internet, I found manual “Pick & place” for SMD. I list in appendix the main articles that inspired me.
I wanted to take advantage of my 3D printer and I wanted a montage taking less space than those proposed, all not too expensive.
- Take a minimum of space
- Use on a desk
The cart where the hand rests can move in X and Y axis. The hand can move up and down the “pen” and turn it on itself. The vacuum pump is activated with a foot switch. A camera can display the work area on a screen. The chosen camera has its own adjustable intensity lighting and has a wheel to adjust the sharpness.
After making the pictures, I thought about the 17% left-handed, I added on the piece of the cart (STL file) 4 other holes to mount the “pen” and the camera on the other side.
The feet are mounted on suction cups to save space and avoid piercing my desktop. I enclose the STL file of the screw feet that I had planned at the beginning.
The “pen” supplied with the pump has a hole on the side. In normal use, the user obstructs or not the hole to catch the SMD. In our case, as we control the pump with a foot switch, this hole should be plugged with a small piece of tape.
