  4. add tape underneath the tag to protect holes for programming from the resin

  5. add EMI shield (temporarily attached in one corner)

Mechanics

  1. resin casting in the mould (Electrolube PU resin UR5528, cca. 60g/piece)

  2. engraving of serial numbers (laser parameters: power 30%, speed 150 mm/s)

  3. prepare screws (2x DIN7985 M3x4 rust-free /tracker)
