METHOD FOR MANUFACTURING LAYERED BUS BAR UNIT

Document Type and Number:

WIPO Patent Application WO/2016/185706

Kind Code:

A1

Abstract:

Provided is a layered bus bar unit facilitating the making of products catering to requirements of different specifications, reducing manufacturing cost including setup costs such as the tooling cost, and ensuring long-term reliability. Coating films 11, 21, are deposited on a first bus bar 10 and a second bus bar 20 individually comprising a flat metal plate by an electrodeposition coating process in which a polyamide-imide electrodeposition coating is used. The coating film 11 on the first bus bar 10 is subjected to a heat treatment to obtain a completely cured resin coating layer 12, and the coating film 21 on the second bus bar 20 is subjected to a heat treatment to obtain a semi-cured resin coating layer 22. The first bus bar 10 and the second bus bar 20 are laid over one another and subjected to a pressurization heating treatment, and the semi-cured resin coating layer 22 is completely cured, thereby forming a layered bus bar unit 1 having a two-layer structure in which the first bus bar 10 and the second bus bar 20 are bonded by the resin coating layers 12, 22.
