FS desktop pcb etching system
I'm selling my unused desktop pcb fabrication equipment made by DynaArt Designs circa 1995.
It includes the Wavemaster, Superfuser, plated thru hole kit and the storage tank. I have 50 sheets of toner transfer paper but can't vouch for its shelf life.
This unique horizontal etching tank has an acrylic shell that holds two fluid pumps, two heaters and a temperature sensor all submerged in the etchant beneath the "wash plate" where the circuit board lays. A GFCI circuit in the external switch box ensures total electical safety.
One gallon of the much preferred Ammonium Persulfate as an etchant is stabilized at 115degrees F by two 50 watt heaters. The built-in 4 digit LCD thermometer electricaly reads out either ethhant or room temperature. Two magnetic-drive centrifugal pumps move 2,000 liters per hour of etchant across the bottom of the tank, forced up a ramp at one end of the tank to form a 1" high waterfall. The falling etchant is then directed across the top of the "wash plate", where the circuit board is placed for etching, before falling back down into the reservoir at the other end of the tank to be recycled again. When power is removed, the etchant falls below the "wash plate" making it dry for circuit board removal. The etchant remains in the tank in-between etchings and when it is fully exhausted, a 1 gallon container, (included), is used for proper chemical disposal.
The Superfuser accepts PCB thichkness to .065", but doesn't specify a minimum thichkness. The boards must be at least 3.75" long because of the roller spacing. The input width is 12 1/3". The transport speed is 40 seconds/inch. The temperature range is 160-360 degrees F
Plated Thru Hole Kit
2@ .026", 2@ .031" and 2@ .040" drills
4 large and 4 small insertion pins
eyelet forming tool (to be used in a drill press)
a few reference sites
http://www.mgchemicals.com/products/416e.html (uses ferric chloride - stains very badly, don't splash on anything)
The literature I have lists the Wavemaster at $300, the Superfuser at $300, the thru hole kit at $70 and the 50 sheet pack at $120. DynaArt is now Pulsar but I couldn't find a price on their latest etcher. I found a different reference fuser for $99 but I don't recall its dimensions or other specs.
The Wavemaster holds a board up to 10" x 8".
This is a good way to go if you are in a hurry, once you are over the learning curve. What's it worth to you?

did you get any nibbles on the etching system?
