12. Place a 3
rd
piece of tape at the end of the step in the groove as shown in
Figure 40. This tape will create a solder dam to prevent solder from flowing into
the l
arger IHS groove section during the melting process.
13.
Measure resistance from thermocouple end wires (hold both wires to a DMM
probe) to the IHS surface. This should be the same value as measured during the
thermocouple conditioning step D.5.1.step 3 (see Figure 41)
