Mounting and Protecting the EBC-C413
The EBC-C413 must be mounted properly to avoid damage.
The
following standoff kits are available and recommended for use with the
EBC-C413:
• KIT-PCM-STANDOFF-4: Four-piece nylon hex PC104 standoff kit
• KIT-PCM-STANDOFF-B-4: Four-piece brass hex PC104 standoff kit
The following table lists the items contained in each kit.
Placing the EBC-C413 on Mounting Standoffs
—Be careful when placing
the EBC-C413 on the mounting standoffs. Sliding the board around until
the standoffs are visible from the top can cause component damage on
the bottom of the board.
Do Not Bend or Flex the EBC-C413
—Bending or flexing can cause
irreparable damage. Embedded computer modules are especially
sensitive to flexing or bending around Ball Grid Array (BGA) devices. BGA
devices are extremely rigid by design and flexing or bending the
embedded computer module can cause the BGA to tear away from the
printed circuit board.
Mounting Holes
—The mounting holes are plated on the top, bottom and
through the barrel of the hole and are connected to the embedded
computer module’s ground plane. Traces are often routed in the inner
layers right below, above or around the mounting holes.
• Never use a drill or any other tool in an attempt to make the holes
larger.
• Never use screws with oversized heads. The head could come in con-
tact with nearby components causing a short or physical damage.
• Never use self-tapping screws; they compromise the walls of the
mounting hole.
• Never use oversized screws that cut into the walls of the mounting
holes.
