5. Connection Procedure (See Figure 3)
The procedure for connecting the RTE7701422CFK144T000R is shown below.
(1) Mount the TC on the target system.
(a)
Thinly apply a two-part curing-type epoxy-based adhesive (with curing
taking at least thirty minutes) to the tips of the four protrusions from the bottom
surface of the TC to be bonded to the target system (before using the adhesive,
use alcohol or another suitable solvent to clean the surface of the target system).
If you have difficulty aligning the positions of the leads of the TC with the pads
on the target system, adopt the method described in (b) below.
(b)
Use guide pins (NQ guide) to align positions attached to the TC by
inserting the pins into the sockets for this purpose on the top of the TC.
These are two or three non-through holes with a diameter of 1.0 mm.
Refer to the drawings of your TC for more information on the socket positions.
(c)
Solder the TC to the target system. If an MA is to be included, attach the
MA before soldering the TC. The MA is used to prevent scattered flux or solder
creating problems by becoming attached to the contact pins of the TC.
Conditions for soldering
Reflow: within 10 seconds at 260
°
C
Manual soldering: within 5 seconds at 350
°
C (per pin)
Cautionary note: Do not wash the flux away by immersion or
vapor treatment.
(d)
Remove the guide pins or MA if they were used.
(2) Attach the EC to the TC.
Attach the EC above the TC after confirming there are neither cracks nor bends
on the contact pins of the EC.
(3) Secure the four corners of the EC with the YQ guide screws that came
with the EC.
Screws supplied with the EC
Use the flathead screwdriver or torque driver supplied with the
EC to secure, in order, the screws at the four corners. The
tightening torque of a YQ guide should be no more than 0.054
Nm. Securing the screws too tightly will lead to faulty
connections.
(4) Attach the pod to the RTE7701422CFK144T000R.
(5) Attach the RTE7701422CFK144T000R to the EC.
Adjusting the height of the socket
The height of the socket is adjustable by inserting an SA between
the EC and the RTE7701422CFK144T000R.
