ABSTRACT:
the enclosure for fully receiving an electronic transponder circuit being of tough synthetic resin material which will not be damaged by being dropped and is intrinsically capable of absorbing shock to a substantial degree when so dropped. The circuit assembly is completely immersed in the circuit assembly in all directions, the cushioning medium providing absorption of impact energy. The silicone cushioning medium when within the closure has its fluid level extending above the seal and above an the enclosure by ultrasonic welding. The transponder repeatedly survives a 2-meter drop test without failure of the circuit assembly. Method for assembling the transponder involves introducing silicone fluid is introduced into the enclosure using a dispensing needle having a tip placed at a closed bottom of the enclosure in order to minimize the creation of air pockets in the silicone, and the predetermined volume of silicone fluid so dispensed is slightly greater than volume available for the silicone fluid after introduction of the circuit assembly.
