| Summary: | Today the rapid development of technology microcontroller , analog
equipment already began to be replaced with digital equipment . Matter of time
and productivity become an important staple in the electrical engineering lab
activities . many of tasks to create a series of PCB are often a waste of time ,
effort and patience in the process of dissolving. Consequently wasted a lot of
things , for it one of the ways is to make automation tool to dissolving the PCB.
Solvent PCB tool is designed with a 1 ampere transformer as power supply , the
main parts of the apparatus consists of dc motor gearbox , engine water pump ,
7segmen , atmega 8515 , push button , and buzzer.for pcb circuit using 3 separate
parts , circuit The first load the driver system , sismin , and relays . The second
series of a series of viewer and push button. third of circuit will be interconnected
with the first circuit with the connector. Alat works by stirring ( up - down )
suitable containers with a set time , if the time to limit equipment operation will
stop and followed by a buzzer sounds for 3 seconds and then the water pump is
active for 5 second. operation Maksimum tool 1 hour 30 minutes , with the
capacity of the container 240 ml - 1 litre with a maximum weight of 1 kg. for
dissolving time ideally 10-20 minutes depending on the area pcb and the many
solvent.
