Real-Life Functional Tests of Conductive Joints of SMD Components on E-Textiles

This article addresses the real-life functional research of electrically conductive joints of SMD components onto the electrically conductive textile stretchable ribbons. The four different connection techniques were used in the research: soldering, electrically conductive adhesive bonding, thermocompression, and non-conductive adhesive bonding. The 20 weeks of testing, including periodical weight training and washing, were realized. It can be concluded that soldering and both adhesive bonding technique are usable. The results showed that the electrical resistance of soldered samples was stable for the whole testing time and can be recommended. The results also showed that the electrical resistance of both adhesive bonded samples was growing at the first few testing cycles and stabilized for the rest many weeks of testing. It follows that also these adhesive bonding techniques can be recommended for some applications where the higher (but stable) joints resistance is acceptable.
