Manual SMT Pick&Place Machine

Hi Everyone,

Recently I have designed a new manual SMD Pick&Place Machine to ease the assembly of my electronics projects. Since I do not want to make money or sell this product I decided to make it open source and share it with you.

The max PCB size is about 250 x 200 mm

The design is quiet simple, has an aluminum frame and some 3D printer parts (I used some leftover parts from my old 3D Printer.)

Basically it has a vacuum pump connected to a vacuum pick & place head. The XY movement of it is guided by linear LM8LUU and MGN12 rails.
Attached to the pick and place head it is a microscope, so the correct placement can be better guided.

The pick & Place head is attached to the machine via four 5x5x5mm magnets and it can be exchanged with an Arduino Motorized SMT Solder Paste Dispenser:

It has SMD strip dispenser for 8, 12, 16 and 24mm tapes.
One SMD components tray with eight compartments, curved side for small SMD components flip-over (0402-1206, SOT23, SOD23 etc.).

Picking a component is done by pressing the left button or pressing down the pedal, this will start the suction pump and close the air valve. The component release is done by releasing the left button or pedal, this will stop the suction pump and open the air valve to fill the vacuum.

The component dispensers assembly needs some gluing. I used fused them together using dichloromethane but any other plastic glue would do the job .

I will update the project files and description as I proceed with the further improvements I plan to do.

Open to-do list:

• solder dispenser not tested yet;
• finish & upload BOM;
• upload connection diagram;
• design a reel support - done!;
• Improved PCB holder - design finished testing open until I receive the frame parts;
• any further suggestions from your side are welcomed.
