PCB Shaking Machine for Printed Circuit Acid Pool
Copper plaque on the printed circuit board after extraction of copper to melt 3 chloride or Perhydrolysis Hydrogen peroxide mixture we use the chloride long copper melts perhidroll acid is a very harmful gas radiates to breathe is dangerous but very fast melting makes
The shaking machine with a simple mechanism in both systems a practical solution for a long time to shake the container we put a plaque or quite useful to inhale harmful gases. Circuit swordfish prepared by the PIC controller used PIC18F2620 Software
