CNC Vacuum table for PCB
thingiverse
This is a cheap vacuum table for holding PCB 100x70 mm (up to 120x100) it's very powerful , impossible to remove the pcb by hand it's powered by a vacuum generator / ejector CV15 plugged into my compressor (50L , 160 L/mn) it need at least 3.5 bar (50psi) to operate and my compressor can hold the charge continuously until 4 bar (58psi) so if your compressor is less than 160 liter/mn (42 gal/mn)then you should use a CV10 instead if you have some difficulty with poor pcb you can add a square of plastic from a plastic bag to add some tightness ( see last picture) BOM (total price around 10€) : 1 vacuum generator (also named ejector) https://www.aliexpress.com/item/1000006280102.html 1 adaptor BSP G1/4 - to your compressor https://www.aliexpress.com/item/33025655573.html 2 pneumatic quick coupling (type PC8-02) G1/4 - 8mm https://www.aliexpress.com/item/32995785954.html 1 tube PU 8mm https://www.aliexpress.com/item/1000006481844.html
