The interposer module is a reel-to-reel feeding module using a left and right sub-module which makes it independent of the Hot Bar length. The module holds a full spool of interposer on the left side and the feeder part on the right side collects the used Interposer material. An intelligent spring mechanism in the module prevents the interposer material from sticking to the Hot Bar after bonding. The tension on the interposer material is automatically controlled through a spring-operated level. The Interposer Module is available in manual and fully-automatic configurations which can be applied to all of AMADA WELD TECH’s Hot Bar systems.
