Etching tank made of plexiglass

This etching tank (both housing and aquarium) is made of plexiglass, because glass aquarium can easily be broken. Another advantage of that material is that it reduces weight of the device. Aeration is carried out by cables and hoses not going outside the aquarium, but through a side wall below the liquid level. Presented idea is based on making three different walls cut of plaxiglass using laser. Stuck together, they act as an inverted siphon.

The whole heats to 40 degrees Celsius within about 10 minutes. The process of etching lasts approximately 10-14 minutes.

Additionally, there is a holder for etched boards and a cover that prevents from evaporation and splattering the solution during the aeration.

Co jest microprocessor digesting?
What is microprocessor digesting?

Re: Microprocessor digesting machine for PCB

Vermes is mostly using on-line translating utilities, unfortunately, without correcting any, even obvious, errors in translation.

Digesting machine => Etching machine.

Under this topic, there are many Digesting machines. :sad:

Food is digested, PCBs are etched

Re: Microprocessor digesting machine for PCB

Ahhh, i thought so...
So much for translating, but creds for making it.
