Many workers in assembling sites typically wear gloves making it difficult to open a Flex circuit connector actuator with fingernails. Also, there were some cases where there is no space for fingers to enter because of high density mounting or because there are parts near the connector.
The Yokowo actuator opener is a tool that makes the Flex circuit connector actuator open quickly without using fingernails.
It can also be effectively used in narrow places where there are mounting parts beside the connector.
