Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: T-tech vs LPKF Posted: Fri Sep 01, 2006 11:49

I am currently contemplating the purchase of a pcb prototyping
machine. The machine will be used to prototype some patch antennas,
microwave circuits, embedded systems, boards for various surface mount
chips evaluations, possibly milling PZT material, and possibly milling
aluminum/plastic for some small mechanical assemblies.
now I am considering machines from both LPKF and t tech. The LPKF system
is about $6K more than the comperable t-tech machine considering work
area and max spindle speed (for my application I think these are probably
the most important concerns). LPKF claims that their machines are more
durable and will last longer than the t-tech machines, but I am not
sure if I really care about a difference between lasting 10 years or
15 years. Anyways, I was wondering if anyone had any experience with
either/both machines and had any comments/complaints that they would
like to share. Thanks

have any experience with the T-Tech, but the group I am at has had an
LPKF for over 12 years and it still kicking. In its infancy it was heavily
used but now is not used as much. We normally have quick protos done
externally (if on FR-4 or similar) or use chemical etching (for Arlon
and Rogers material).

I worked for
1 year in a company that had an LPKF machine (As far as I remember it
was the C-60 model). LPKF is a good choice for what you are looking
for. I remember that it had a good quality and reliability. We used
it for prototyping of relatively big boards in quantities of up to 10
units. This was because we manufactured units for demonstration and
by that saved a lot of money for external PCB manufacturing.

I pull this old topic because we definitely need
a PCB prototyping machine.Applications planned, RF, embedded systems,
small number of antennas and plastic front panels.
I found a
lot of positive words for LPKF, but the price is what bothers me.
(new S62 $22-24K, S42 over $10K and specs below my needs)
T-tech doesn’t catch my eye due to some (not so positive) expressions
form an owner of 3 years old machine.
Really prefer new machine.
Lately I found this one http://www.accuratecnc.com
looks very good. Demo software loads all my projects perfectly.
quote from Accurate is approx 1/3 of LPKF.
I need advise for:
- any one that have more info about Accurate 360 ?
- Other brands
of PCB prototyping machines that are similar class?
