Hirose BM10 Series Manual

0.4mm Contact Pitch,Stacking Height 0.8mm Board-to-Board /Board-to-FPC Connectors
BM10 Series
■Features
1. Higher density of the board-mounted
components
Extremely small board mounting pattern and low above the-
board profile makes the connectors ideally suited for small
device applications.
Globally unrivalled compact depth : when mated 2.98mm
Length - world's smallest class : 10.4mm
2. Reliable electrical and mechanical connection
Despite its small mated height, unique contact configuration,
with a 2-point contacts and effective mating length of
0.2mm(height 0.8mm), assures highly reliable connection while
confirming a complete mating with a definite tactile feel.
3. Large self-alignment distance
The connectors will self-align within 0.3 mm.
4. Built-in shock absorbing feature
The protrusions and indents in the insulator bodies protect the
connectors from failures when exposed to sudden impact.
5. Solder wicking prevention
Nickel barriers prevent un-intentional solder wicking.
6. Contamination protection
Insulator walls protect the contact areas against flux splatter or
other physical particles contamination.
7. Conducive traces on the PCB can run under
the connector
No exposed contacts on the bottom of the connector.
