3U / 6U & EUROCARD / VME PROTOBOARDS
Protoboard-3U w/con-
nectors
Pads are connected in groups of six,
bridging these groups with dual in-line compo-
nents can save a lot of assembly time. The
board has footprints for standard sized DB-9
and DB-25 connectors as well as BNC’s,
phone jacks and a coaxial power connector.
Pads are also provided to accommodate a
SPDT switch. Holes are, of course, spaced on
0.10” center and each is .037” in diameter.
The board material is etched FR-4 glass-
epoxy with one ounce copper on both sides,
tinned for easier soldering. The board size is
3.9” X 6.3 x 1/16” (100 x 160 x x 1.6mm).
Total holes are 38 rows by 62 columns.

SMT ProtoBoard 3u thin
Note that this SMT product is available in a standard
1/16” thickness as well as in the 1/32” thickness that is needed in some
applications. See below for part numbers.
Surface mount pads are spaced for 0805 and 1206 components. Three
SOIC-32 footprints can handle IC’s with up to 32 contacts. A solid ground
plane on the backside can be reached via drilled holes for connection to the
ground plane. The holes are not plated through, allowing the user to choose
to make a connection (“via”) with a jumper wire or not. A backplane makes
this an excellent board for R.F. circuits as well as digital and analog.
There are a dozen SOT23 footprints and the rectangular pads will accommo-
date SOT223 and as well as SOT23 components. As the rectangular pads
are spaced on 1/10” centers, leaded components such as DIP IC’s will fit
well. Mounting holes (4) are in the corners. The board material is etched FR-
4 glass-epoxy with one ounce copper on both sides, tinned for easier solder-
ing. The board size is 3.9” X 6.3 x 1/16” (100 x 160 x 1.6mm).

StripBoard-3U
The StripBoard layout is
very popular and found
in many different (often
cheap) materials. This
one is much superior as the
FR-4 material does not warp or suck
up moisture from the environment. It
can be recommended for R.F. circuits,
digital etc.
Copper thickness is a standard one
ounce single sided. Holes are on 0.10”
center and are .037” in diameter (for
IC’s etc.). The strips can be “broken”
with your model knife to create sepa-
rate areas, mount IC’s, connectors etc.
. The board is a standard 3U
Eurocard size at 3.9” X 6.3 x 1/16”
(100 x 160 x 1.6mm). Total holes are 38 strips, each with 62 holes.

SMTpads-3U thin
Good as a general purpose board for
Surface Mount Technology circuits, the
board has 42 mil copper squares on 50
mil centers. SMT components of various
sizes and pitch (contacts per inch) may
be mounted easily (see illustration).
SOIC components, which are a 50 mil
pitch and DIP components, which are a
100 mil pitch, can all be used on this
board.
A solid ground plane on the reverse side
of the board will provide low noise for
amplifiers, solid for RF circuits etc. Both
sides are one ounce copper. There are
.031” holes through to the backside
every four pads; holes are not plated
through so that the user has the option
of creating a via with a jumper wire, or
not.
A Flux coating keeps the board prepared for soldering and prevents cop-
per from oxidizing.
The board is a standard 3U Eurocard size at 3.9” X 6.3 x 1/32”
(100 x 160 x 1.6mm).

StripBoard-6U
Traces run the full
length of the board.
The board is single
sided, and copper is
tinned. Holes are on
0.10” center and are
.037” (.94mm) in diam-
eter (for IC’s etc.). The
strips can be “broken”
with your model knife
to create separate
areas, mount IC’s, con-
nectors etc. The copper thickness is a standard one ounce.
The board accepts two standard 64-pin or 96 pin DIN-41612 con-
nectors for backplane applications or expansion. The connector
footprint gives access to connector rows 1 and 3; row 2 pads are
unconnected.
The board is a standard, double-height 6U Eurocard size at 9.2 X
6.3 x 1/16” (233.4 x 160 x 1.6mm). Total holes are in 180 traces,
90 x 62 holes.
