Budget bubble etch tank - model ET20 ?

Budget bubble etch tank - model ET20 ?

2005-10-26 by Richard

www.maplin.co.uk have one : order code N53BY for GBP �39-99

So do www.circuitspecialists.com for the same amount in $ USD  !

This is exactly same model, except for the supply voltage.

The price difference is unbelievable.. 

Has anyone purchased an ET20 from another supplier in the UK ?


Thanks - Richard

US$ = UK\ufffd is not too bad. Allow 10US$ for shipping (low estimate 
considering the size/weight)...

39.95 + 10 = US$49.95 = \ufffd29.38 (1.7 exch rate) + VAT = \ufffd34.52

So, you are going to save around \ufffd5 by purchasing from the US  (even 
less if they catch you for import duty) -  not worth it.

Every US price in USD is 'converted' in UK to the same figure in GBP.
You have to know that.

Thanks Andy & Cristan - 

Yes, agreed, stung by £10+ import duty does sort of make the UK 
purchase option the best buy all round :)

No, I didn't realise about the $1=£1 'conversion' - unfair, I'm sure 
you agree.... so much for foreign exchange rates.

Hi,

It isn't the exchange rates that are a problem it is customs duty and VAT @
17.5% then add in the postage. I have bought a lot from the States and if it
is under about $50 and sent from a friend they usually let it through.

Regards,

Terry

The problem with this tank is not just the price... :-(

I bought one a few weeks ago and was very disappointed..

I ordered online and first off the heater was broken..  
the packaging was whlly inadequate.

I returned it and was still disappointed when the replacement came.

The tank itself is fine, the air pump is fine, but the heater was 
obviously substituted with a unit designed for aquariums ...  
although it is adjustable, it will not adjust to the 40 degrees 
celsius needed for efficient etching. In fact 33 was the maximum!

Anyone who has etched boards in quantity will tell you that it will 
be considerably slower.

The manufacturer of the tank is Velleman and I checked their site 
for this product and the original heater IS supposed to be a 40 
degree type.

In the end I rooked around in my shed and came up with a heater for 
beer that can be adjusted to 40.

I phoned Maplin and spoke to customer servives and their reply was 
to the effect that nowhere on the advertisement does it state that 
the tank heats the fluid to 40 degrees.

I tried to enter a review of the item on their website but for sme 
reason, it seems to have been censored out !

I wonder why !

Dont get me wrong, I generally applaud Maplin for their service and 
range, they are a useful supplier when the normal suppliers haven't 
got stock etc.   but in this case, they are just plain wrong.

If you want to etch boards in any sensible time, you will have to 
buy a different heater...

Hi Chris

Thanks for useful info, especially interesting to know that the 
manufacturer of these units is Velleman.

I've read about these arriving with broken heaters elswehere, one 
individual having to return it 4 times, until he got one that wasn't 
smashed...

As for the temperature, the website here : 
http://computronics.com.au/kinsten/et/ (Australian), claims a heater 
temperature for both the ET10 & ET20 models of 60C - way higher than 
your measured 33C !  - might be worth checking out what Velleman 
themselves have to say about this - spec sheet etc...

Maplin : yeah, they are pretty good, but still pack everything 
possible into 'jiffy' bags, (if they can find one big enough).. 
Packing is certainly NOT their strong point, forgive the pun ;)
As for refusing to post your comments, I'm not at all suprised.

Richard

Re: Budget bubble etch tank - model ET20 ?

2005-10-27 by lcdpublishing

So far, my cheapo homemade bubbler tank is working pretty good. 
Don't know the total cost of everything but this is what it is...

A tupperware container I got from Walmart - about $2.00, Holds about 
an 8" square board.

An aquaium pump, hose, and a bubbler stone (?) - about $7.00 at 
Meijer (something like a walmart).

What I like - it's cheap.

What I don't like, the bubbler stones.  I can't seem to get them to 
stay on the bottom where I want them.  I am going to, when I have 
time, empty the tank of Ferric Chloride, and silicone the stones to 
the bottom of the tank and see if that holds them where I want them.

I don't use a heater as I am 96.37% sure someone told me not too, so 
I don't.  I have not etched a lot of boards, about 15 or so, so 
please take my comments for what they are worth :-)

The heater got me really hot under the collar !  (lol)

I now have to eat at least a little humble pie  (I'm used to it.. 25 
years of marriage !)

This relates to the original hater supplied with the kit 
marked "BOYU aquarium heater"

I was so annoyed with the heater, I just took the original to bits 
and It CAN be altered to get the temperature range..  so the problem 
may not be as bad as I thought..

If anyone else buys one..  here is what to do !

gently prize the plastic top off along the centre line of the 
heater, it is a push fit.

turn the temperature adjustment up to full  eg with the legend "32" 
visible.

remove the screw that holds the thumbwheel onto the shaft

cut off the stop on the back of the thumbwheel with a knife !

refit the thumbwheel onto the shaft in the same position as it came 
off !

press the cover back into position !

You now have a heater that will go up to 40 degrees or more.. just 
have to guess the position f the wheel..

I used a pyrometer to check the temperature and the scale seems 
pretty linear..

Re: Budget bubble etch tank - model ET20 ?

2005-10-27 by Chris Horne

A heater really is worth it..
40 degrees Celcius  or about 107 degrees Fahrenheit.

In the ET20 I can put two single sided boards back to back and they 
will etch in less than 5 minutes..   and the time is consistent so 
that I don't have to watch the board closely each time.. 
(I tend to do 10 or 20 boards each session)

It is particularly valuable when the solution gets a bit tired...  
it seems to be usable for longer..

I actually run my tank sitting in the kitchen sink, and I use press-
n-peel etch resist ironed on..  The tank etches them faster than I 
can prepare and iron on the film..

previously I was waiting for the board to etch for up to 10 minutes 
after I had prepared the next pair of boards..

I actually prefer the ET20 to the old three tank system I used to 
use...  since i no longer use a developer, i only need one tank and 
a tap to rinse...  it is easier cleaner and takes up less space.

re holding down the bubble block...

you could try hot glueing a strip of stainless steel to the bottom
I haven't tried it but would be interested in the result

(I checked a bit of SS in my etch solution and it looked unaffected)

Another example of "rip-off" Britain I'm afraid
