Operation

Figure 2: Flare the eyelet barrel.

If needed, drill out the plated hole removing all the plating. The drilled hole should be .001" - .005" (.025 - .125 mm) larger than the eyelet outside diameter. Use caution when working on a circuit board with inner layers.
Insert the proper Setting Tool into the Tool Holder installed in the base of the Eyelet Press. The small tip of the lower Setting Tool points up. The large tip of the upper setting tool points down. (See Figure 1)
Insert the proper Setting Tool into the ram of the Eyelet Press. The larger cone end of the Setting Tool should be facing down. No tightening should be needed; springs inside the ram should hold the Setting Tool in position. (See Figure 1)
Figure 3: Flatten the eyelet barrel.

Insert the Eyelet into the hole in the circuit board. The flat flange of the Eyelet should be on the underside. This is needed to ensure you can observe the flaring process. If needed, place a small piece of tape over the flange of the Eyelet to prevent it from falling out of the circuit board. Pierce a small hole in the tape to help center the tip of the lower Setting Tool.
Lower the ram of the Eyelet Press and flare the barrel of the Eyelet by applying moderate force using the Eyelet Press. (See Figure 2)
Change the upper Setting Tool so the small cone tip end of the Setting Tool is facing down. Apply firm, even pressure to flatten the eyelet barrel. (See Figure 3)
