MODULE CONTACT FINGER AND MODULE CONNECTOR BLOCI(
CONTACT IDENTIFICATION
DIGITAL plug-in (FLIP CHIP) modules have contact fingers either on one
side (single-sided modules) or on both sides (double-sided modules). Mod·
ules with contact fingers on only one side always have them on side 2 (the
solder side) (Figures 6, 7, and 8). DIGITAL module connector blocks have
module slots with contacts either on one or on both sides. Modules with
contact fingers on only one side can be plugged into connector blocks with
contacts on both sides of the module slots; then electrical contact between
the module and the connector block is only via module slot side 2 contacts.
The module contact fingers and connector block contacts are identified by
alphanumeric codes. These alphanumeric codes are used throughout this
handbook, the HARDWARE ACCESSORIES CATALOG, the PERIPHERALS
HANDBOOK, individual module data sheets, engineering drawings, and other
DIGITAL publications. This coded numbering scheme must be understood to
ensure proper system interconnections (Figures 6, 7, and 8). Letters G, I,
0, and Q are not used in this numbering scheme.
DIGITAL modules are SINGLE·HEIGHT, DOUBLE-HEIGHT, or QUAD·HEIGHT;
STANDARD LENGTH or EXTENDED LENGTH; and SINGLE·WIDTH or DOUBLE·
WIDTH (Figures 6, 7, and 8). Each DIGITAL module is a specific, fixed size;
the size of each module is stated in the module description in the previously
mentioned DIGITAL publications. DIGITAL SINGLE·HEIGHT and DOUBLE·
HEIGHT modules are STANDARD LENGTH or EXTENDED LENGTH. DIGITAL
QUAD·HEIGHT modules are always EXTENDED LENGTH. Any DIGITAL module
can be SINGLE·WIDTH or DOUBLE-WIDTH; most, however, are SINGLE·
WIDTH.
The height and length requirement is determined by the quantity and size of
discrete components and integrated circuits located on side 1 of the module,
and, to some extent, by the amount of etched printed circuitry on sides 1
and 2. The width requirement is determined by the distance the largest
component extends from its mounting surface on the module.
All DIGITAL module connector blocks accommodate any height (standard or
double) module. The length of the modules to be used in a logic system
must, however, be considered when connector block mounting drawers,
system unit mounting drawers, or cabinets are being selected; enough space
must be provided to accommodate the longest module. DIGITAL's STAN·
DARD-LENGTH modules are 5.40/5.60 in. (13.72/14.22 cm) long and EX·
TENDED·LENGTH modules are 8.84/9.04 ,in. (22.58/22.96 cm) long from
the bottom of the contact fingers to the top of the attached handle(s).
All DIGITAL module connector blocks accommodate any width (single or
double) module. The width of the module must be considered, however,
when any connector block module slot is occupied by a DOUBLE·WIDTH
module; this is because no module can be inserted into the module slot on •
the immediate right on the same connector block unless that connector
block provides sufficient space between module slots for the mounted components, i.e., an H808 Module Connector Block. DIGITAL's SINGLE-WIDTH
modules require 0.338/0.348 in. (0.859/0.884 cm) for conductive components and 0.370/0.380 in. (0.940/0.965 cm) for nonconductive components.
DOUBLE·WIDTH modules require 0.820/0.839 in. (2.106/2.131 cm) for conductive components and 0.870/0.880 in. (2.210/2.235 cm) for nonconduc·
tive components. These component space requirements are the distance from
the module's side 1 surface to the side 2 surface of the module mounted
on the immediate right. Normal module spacing is on half·inch centers.

Some DIGITAL module connector blocks accommodate only SINGLE-HEIGHT
modules and others accept either SINGLE-HEIGHT or DOUBLE-HEIGHT modules_ No single connector block can accommodate QUAD-HEIGHT modules;
QUAD-HEIGHT modules must be mounted in mounting frames, system units,
or module drawers comprising module connector blocks with slotted ends so
that four module slots are arranged end to end (Le., at least two H863 or
H8030 Module Connector Blocks mounted end to end). SINGLE-HEIGHT
modules are 2.417/2.452 in. (6.139/6.228 cm) high, DOUBL.:E-HEIGHT
modules are 5.167/5.202 in. (13.124/13.213 em) high, and QUAD-HEIGHT
modules are 10.437/10.472 in. (26.510/26.599 cm) high (Figure 9).
SINGLE-HEIGHT modules (standard length and extended length) may be
plugged into the upper (row A, C, or E) or lower (row B. 0, or F) module
slot of a connector block (Figure 9). Contact fingers Al through VI are on
side 1 (component side) of the module, and contact fingers A2 through
V2 are on side (solder side) of the module (Figure 6).
DOUBLE-HEIGHT modules (standard length and extended length) have two
plug-in sections of contact fingers and occupy two module slots (rows A and
B, C and 0, or E and F) of a connector block (Figure 9). The two plug-in
sections are identified by the designations A and B. Contact fingers Al
through VI and A2 through V2 of the A section are designated AAI through
AVI and AA2 through AV2, respectively; contact fingers Al through VI and
A2 through V2 of the B section are designated BAI through BVl and BA2
through BV2, respectively (Figure 7). Note that the positioning notch in the
module base must mate with the protrusion on the connector block for
correct positioning.
QUAD-HEIGHT modules (always extended length) have four plug-in sections
of contact fingers and occupy four module slots (rows A through 0 or C
through F) of two connector blocks (Figure 9). The four plug-in sections are
identified by the designations A, B, C, and D. The four sections of contact
fingers are deSignated AAl through AVl and AA2 through AV2; BAl through
BV1 and BA2 through BV2; CAl through CVl and CA2 through CV2; and
DA1 through DV1 and DA2 through DV2 (Figure 8).
