Greetings, Vassili!

<13:10> Vassili Klimov wrоte to All:

VK> Dimensions 25x40 cm. And the board has all the modifications:

It turns out 10dm^2...

VK> This stuff costs $20 in the form of a board.

This cost is obviously bare boards...

2$/dm is a very cheap price for wholesale production of boards...

In any case, for high-quality boards in St. Petersburg it is, but it’s normal
for 2.5-3$/dm.

By the way, to follow up...
PLM ACEX1K10 currently costs $12
The number of cases that can be squeezed into it is ~100 pieces average
degree of integration.

If you fill everything with K555TM2s, you will get 288 pcs;
All KP11 - 144 pcs; All TM9 - 98pcs. etc.


And so we calculate that the Zonov board is ~40 cases - ~3dm. 100 cases ~2.5
Zonovsky, compressing the whole hundred even by 5 dm with the "St. Petersburg" cost of manufacturing
the board turns out to be 12.5 $, the board itself turns out to be a PLM... Plus to it
100 microcircuits, plus a hemop in soldering/adjustment and it turns out that the PLM is 0.5 dm
cheaper and better quality than 100 cases on plywood... (at a cost of even
0.05$ per case, 100 m/s with a board will definitely cover the cost of PLM)


P.S. This is not an advertisement for PLM or Sprinter (in Sprinter PLM is 3 times larger in volume), it is a hint to board designers on how to reduce the cost, reduce and
improve...


The protoss have escaped. The zerg dug in. It's time for me tooзакругляться. Ivan.

Correct.
But this is in St. Petersburg, Moscow... There you can do it on PLM, but here it’s not like that. And not only
with us.

All the best.
Roman.
