| Popis: |
Rechargeable shapeable Lithium batteries have been in research and development by Philips in the last years resulting in an option to optimize the size of a System-in-Package. In a previous work, it was shown that gluing can replace ultrasonic welding in low power applications, nevertheless, the glued contacts require of a material to protect them from humidity in order to avoid corrosion. In this work, the reliability of the glued and welded contacts is studied, when protected by a glob top material. The contact resistance of the bonds is measured before and after a high humidity and temperature aging process. If the contacts present a change of resistance of less than 20% after the reliability test, the test is considered a pass. The welded contacts presented a change in resistance of less that 20% and the glued contacts of at least 50%. The welded contacts protected with a high purity UV curable material are the most reliable. |
