Eyelet Selection Criteria
ID - Inside Diameter.003" - .020" greater than the component lead diameter.
OD - Outside DiameterThe clearance hole in the circuit board should be .001" - .005" greater than the outside diameter.
LUF - Length Under FlangeThe length of the flange should be .020" - .035" greater than the thickness of the circuit board.
FD - Flange DiameterThe flange diameter should be small enough to prevent interference with adjacent pads or circuits.

Eyelet Press Setup
  1. Be sure the Form Tool and Anvil Tool are perfectly aligned. The tips should touch when the press is lowered. If the tips are not aligned, loosen the four mounting bolts and adjust as needed.
  2. Mount the Setting Tool, with the stationary tip, in the upper Tool Support.
  3. Mount the Anvil Tool, with the spring tip, in the lower Tool Holder.
  4. 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.
  5. CAUTION: Use caution when working on circuit board with inner layers.
  6. Insert the Eyelet into the circuit board and flare, or flat, set the eyelet flange by applying moderate force using the Eyelet Press.
