However, our thermoelectric cooler (module) uses no solder but flexible resin glue between cooling ceramic and copper electrodes. This decreased thermal stress and dramatically increased life. We call this structure as GL (Glue=Adhesive) structure.<\/p>\n<h3 class=\"line_left\">Solution by moisture proof sealing for &#8220;rust&#8221;, &#8220;breaking&#8221;, &#8220;short&#8221;<\/h3>\n<p>Our thermoelectric cooler (module) has passed various temperatures switching tests, on\/off tests, and so on with very good results.
