Section 2 Connection Procedures
2.1 Connecting User System Interface Board to User System
WARNING
Always switch OFF the user system and the emulator
product before the USER SYSTEM INTERFACE CABLE
is connected to or removed from any part. Before
connecting, make sure that pin 1 on both sides are correctly
aligned. Failure to do so will result in a FIRE HAZARD and
will damage the user system and the emulator product or
will result in PERSONAL INJURY. The USER PROGRAM will
be LOST.
To connect the cable head to the user system, follow the instructions below.
2.1.1 Installing IC Socket
Install the socket for BP-272 packaged ICs on the user system.
(1) Gently apply solder to the BGA pads of the user system. Be careful to keep the thickness of
the solder within 100 to 150 µm. Too much solder will cause short-circuiting of the pins.
(2) The IC socket is vacuum-packed to avoid oxidization of the surfaces of the solder balls. It
is thus recommended that the IC socket be installed on the user system immediately after
the package is opened. After the package’s seal has been broken, store the socket in a
desiccator. Do not touch the solder balls. If they are touched, solder may not adhere to the
solder surface.
The IC socket is covered by a protective cover. Socket and cover are fastened together by
four screws before the whole is vacuum packed to prevent bending of the IC socket’s pins.
To avoid the scattering (dispersal) of flux from other components to the IC socket, keep the
protective cover on the IC socket until solder reflow has been completed.
(3) Install the provided guide pins into the holes for the guide pins on the user system. Check
that the pads are correctly aligned with the IC socket.
