PCB etching tank heating

[Fusion916]

Any suggestions on a fully submersible heating apparatus I can use in a pcb etching tank that will go up to 50C?

I have been using aquarium heaters and they "work" but they only go up to 35C, which leads to long etching times.

Here, I bought couple of these heaters especially designed for bubble etching tanks. They can reach 55-60ºC -> 1x Kinsten Etching Plating Heater Eph 20 300W 110V Taiwan | eBay

Yes, that will do if you're lucky enough. Pulling the rubber seal without breaking the glass is pain in da butt. Been there, done that.

Wow nice exactly what I was looking for, thanks.

Do you know of any good PCB holders and water tank agitators?

Well you can use plastic clips, a common aquarium air pump and an aquarium bubble wand. No special recommendation since there are bunch of quality pumps out there. I made my own PCB processing tanks with acrylic glass. There are 3 processing tanks, etching compartment, washing compartment and developing/stripping compartment. The heaters are controlled with the microprocessor temperature controller. I stole the idea from Mega Electronics UK, PA310 Tri-Tank Unit -> Mega-UK - PCB Processing Tanks Will soon post some of my pics soon.
