Abstract

Leak testing is rapidly becoming a standard pro- cess requirement for many electronic products, partic- ularly those that must survive certain environmental specifications such as water resistance. In many instances, the electronics are packaged in a ported housing to allow for pressure equalization venting. Additionally, some products are powered by zinc air batteries that must "breath" in order to operate cor- rectly. A series of angled cosmetic grooves conceal the port on the pager. In order to leak test the product, a vacuum nozzle is applied to this area.
