Hi Minimos,
I made a revision for the PCB for factory or PnP/UV, so far the main board. Not
to much free time this week, it was snowing like hell here.
Some infos:
Pads - 0.086 (~2.2mm) Transistors are 0.076
Routes - 0.04 inch
Space between ground plane and routes 0.012 inches (~0.3mm) - a little close
but I believe will work for PnP.
Holes - 0.031 (0.8 mm) Trimmers 0.039 (1 mm)
Please check if ok. You can print the layout and see at 1:1 if ok. Pdf file is
A4 size paper.
The board is a liitle larger now (~5mm on each side) because I wanted to add
more gnd plane.
I added some extra holes at trim caps if you want to put small package trims
with 3 pins.

Dear friend,
Is the module Si570, for the Minima is
available in VU land ..?
If so where and what may be the
price.

If the adhesion is not good, copper detaches from the board on
heating, specially in smaller pads/thin tracks. I think G5V2 and G5V1
equivalent relays are available in local markets in VU land. These
are
commonly used in some EPABX's. Larger relays with similar foot print
are also available. If spacing is not adjustable, vertical mount
should be OK. Two terminal trimmers are now seen in local markets too
so these should be fine too.
