This document introduces recommendations to manually mount EnFilmTM micro battery EFL700A39 on printed circuit board (PCB) for prototyping purposes
This document provides recommendations for manually mounting the EnFilm™ micro battery EFL700A39 on a printed circuit board (PCB) for prototyping purposes. It covers PCB design guidelines, such as pad size and finishing, and details the use of Circuit Works® Conductive epoxy CW 2400 for assembly.
The guide outlines a specific mounting procedure involving surface cleaning, mixing and applying conductive glue dots, and placing the battery with a weight for curing at room temperature. It also notes that underfilling is not required and that the conductive glue does not allow for rework.
