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.

Right 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

Do not 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.

Hello,
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

Specs looks very good. Demo software loads all my projects perfectly.
The 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?

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
