Soldering Ic Socket; Inserting Cable Head; Fastening Cable Head - Renesas H8/325 Series User Manual

2.2.2

Soldering IC Socket

After fastening, solder the IC socket for an FP-64A package to the user system. Be sure to
completely solder the leads so that the solder slops gently over the leads and forms solder fillets.
(Use slightly more solder than the MCU.)
2.2.3

Inserting Cable Head

Check the location of pin 1 before inserting.
Align pin 1 on the IC socket for an FP-64A package on the user system with pin 1 on the user
system interface cable head, and insert the user system interface cable head into the IC socket on
the user system, as shown in figure 3.
2.2.4

Fastening Cable Head

1. Use a Phillips-type screwdriver whose head matches
the screw head.
2. The tightening torque must be 0.0784 N•m or less.
If the applied torque cannot be accurately measured,
stop tightening when the force required to turn the screw
becomes significantly greater than that needed when first
tightening. If a screw is tightened too much, the screw
head may break or an IC socket contact error may be
caused by a crack in the IC socket solder.
3. If the emulator does not operate correctly, cracks might
have occurred in the solder. Check conduction with
a tester and re-solder the IC socket if necessary.
Fasten the user system interface cable head to the IC socket for an FP-64A package on the user
system with the four screws (M2.0
a time, alternating between screws on opposing corners. Take special care, such as manually
securing the IC socket soldered area, to prevent the soldered IC socket from being damaged by
overtightening the screws or twisting the components.
