Greetings Riston users,                          rcsradio.com.au

OK, for 30+ years I have NOT used this developer/stripper combination
mainly because of cost, as for us, in bulk manufacturing, a saving of 10 
dollars per hundred square foot, is something to be always considered.

Now this is page 2 of 2 sections, Developer and Stripper.

STRIPPER   (CCRS600M or CCRS5000)                   September 22 2001

Why should you use this Stripper, and not the more common industrial
circuit board strippers, (hot caustic soda) well, the simple reason is
you only have 1 set of EYES and whilst I use it with no employees present, 
I call it hazard chemical handling, dumb, stupid, yes, but real cheap. 

After you have etched the board in Ferric Chloride or Ammonium Persulphate
(that's another story), and the board appears to be fully etched where
you want it to be, the next item of business it to remove the Riston 
Track Protective coating by simply immersing the board into a tray
of this solution.  It does work in room temperatures but does favour
some 40ºc to 50ºc, again this solution brew was concocted by Doug Rees of 
Circuit Comps of Bexley, he has made this brew, (and now under his guidance, 
I do the same also). The object is to remove the RISTON, any way 'SAFE'

We batch/sell this in 600ml and 5litre plastic handy carry bottles, 
(why 600ml, well we purchased so called 500ml plastic bottles and when
filled with 500ml of solution, it was about 3/4" (20mm) from top neck
and rather than it look like you are being 'short changed' we make it 
600ml, (and charge you extra), as we will NOT add water, to build it up. 

Room lighting can be anything but by keeping it UV free, using yellow 
Cellophaned 20w fluro's or 25w incandescent lamps with dimmers set at 
1/2 way point you can always do a quick area etch prior to stripping.

The STRIPPER does NOT need to be 'warmed' up, as normal room temperature
is quite ok, maybe a bit slow, but up to 40ºc to 50ºc is quite normal. 

Then slosh/brush over surface until all areas of RISTON track have gone
bubbly and have been removed and the board is now showing shiny copper 
tracks where your pads and tracks for the final prototype.

Tip the solution back into a 'B' bottle, and re-use until stripper time 
has been extended far too long, and/or mildly warm up to a max of 50ºc.

Normal Stripper time, according to our in house testing conditions is 9mins

Rinse in water quickly, dry, and for the hobbiests, start drilling.

RISTONRS.txt       This page may expand as I get feed back of any drama's

P.S. RCS will be offering a rolled solder finishing service on saturdays 
soon, so as your board looks a tad professional. send email asking.

I have to add, after using some test trips in this stripper, I have fully
converted my auto stripping machine, over to 'Dougs Stripper' on Sep 20 2k1

Now, as I indicated earlier the stripper is far better than the ones I have
used over the past 30+ years, and I noticed that in using it, the riston
came off in 'lumpy plastic glugs', what I suggest now is that after tray
stripping, you pour the stripper solution back into the 'B' bottle via a 
'scotch brite' (and funnel) and separate the 'blue gluggy' mess, and reuse
the stripper, many many times, until complete exhaustion has been reached.
After pouring back into the 'B' bottle, wash/rinse the scotch brite, re-use.

Yes we will sell less stripper, but you will be 'hooked' on the life duration
So summary, separate the blue gluggy stuff = extended life of the product.

We recommend you purchase this solution from JAYCAR (in your local area) but
if you are stuck, yes we will sell it over the counter also
