Description

TECHNICAL FIELD

Embodiments of the present disclosure generally relate systems and methods for retention of a flexible substrate on a reusable carrier to manufacture electronic assemblies.

BACKGROUND

Wearable technology is a category of electronic assemblies that are worn by a consumer. Wearable technology often tracks information related to a consumer's health or fitness. Most wearable technology is worn on a consumer's wrist, but an increasing number may be clipped to the body, worn around a finger, hung around the neck, or sewn into various garments worn by consumers. Wearable technology is becoming widespread as the Internet of Things expands its reach.

Wearable technology often includes electronic assemblies built on flexible substrates. The flexible substrates may be temporarily restrained or fixed to a carrier to ensure that the substrates remain relatively rigid during the processes that place and permanently attach electronic components to manufacture the electronic assemblies. At the end of these processes, however, the flexible substrates with the permanently attached electronic components may be removed from the carrier for further processing or packaging. The flexible substrates may be temporarily fixed to a carrier using double stick tape but the tape may be used a limited number of times before requiring manual cumbersome and costly replacement.

In an embodiment, head 206A may contract horizontally by e.g., pinching or otherwise bringing together head 206A, to ease insertion of head 206A into substrate registration feature 203.

Once substrate 202 is secured to secondary carrier 204B by inserting head 206A into substrate registration feature 203, a vertical length of secondary carrier registration feature 207 receives primary carrier registration feature 205 to removably fix flexible substrate 202 to primary carrier 204A and secondary carrier 204B. In an embodiment, insertion of primary carrier registration feature 205 into a vertical length of secondary carrier registration feature 207 may expand head 206A or body 206B of fastener 206 substantially horizontally against substrate registration feature 203 of flexible substrate 202 to removably secure flexible substrate to primary carrier 204A and secondary carrier 204B.

To detach substrate 202 from primary carrier 204A and secondary carrier 204B, primary carrier 204A is first removed by sliding primary carrier registration feature 205 from secondary registration feature 207. Thereafter, fastener 206 may be pinched at head 206A or body 206B to release substrate 202. Use of fastener 206 on secondary carrier 204B allows reuse of primary carrier 204A and secondary carrier 204B to manufacture a subsequent electronic assembly on another flexible substrate 202.
