It is an automatic tilt-table style etching tank that will keep the ferric chloride (or similar) moving across the PCB, thus minimizing the etching time.

Everything is included in the package, schematics, PCB layout and full source code.

Uploaded RAR version.

This project uses a hobby servo to pivot a plastic tray up and down, swashing the ferric chloride back and forth to decrease home-made PCB etching time.

  • PIC16F88 with 8MHz internal oscillator.
  • Two timers are used, one to keep track of time, and the other to pulse out the servo signal.
  • PORTB change-on-interrupt
  • Count up and Countdown mode
  • A 16x2 LCD is used for menu display.
  • A rotary encoder is used for menu navigation.
  • A LED and a Buzzer is used for feedback
  • Settings are saved in EEPROM
  • ICSP
  • 9V - 18V AC or DC @ approx 500mA
