LumaSHIELD Installation Guide: Spacer Disk
Instructions
1. As shown in Figure 1, use polyimide tape to hold the
probe tip on a hot plate and put the spacer disk in
position. The location of the spacer disk depends on
the paper board structure (Refer to Figure 2).
2. Turn on power of the hot plate and warm the tem-
perature to around 93 °C.
3. Mix the two-part epoxy Aremco 631 with weight
ratio 1:1.
4. Use a piece of optical fiber or a toothpick to apply
the epoxy to the gap between the fiber and the
spacer disk as shown in Figure 1.
In case of epoxy flowing onto the hot plate, the
epoxy should be applied several times. For example,
apply once and cure it for 10 minutes and apply it
again until the epoxy filled the gap. After two hours
curing, the epoxy should be flush to the spacer disk
surface.
