Maintain Electrical Connection

Connect without Masking

We conducted a test at the University of Auburn to measure the impact of Repellix on the contact resistance of a typical flex connector. Three connectors were pre-measured, then sent to IST for coating with Repellix, and returned to Auburn for re-measurement.

IST used three different versions of Repellix for this test: from the least durable to the most durability.

The results for all samples showed no significant difference in the pre and post measurements. We conclude that Repellix can be connected through with flex circuit connectors. Measurements are in mOhms.

The reason Repellix can allow good electrical connection without masking is the controlled durability of its supermolecular structure. Although ceramic-based, we engineered the interlinking bonds loosely enough that the metallic prongs of the connectors can pierce through to contact with their partner terminals. An example is depicted on the left. The photo of one of the three prongs of a cellphone battery terminal shows that the Repellix coating was scraped away by the metal-to-metal contactors when the phone was reassembled.

Looking into the female end of a Hirosi style connector, we see raised barbs that are intended to penetrate the male blade and make excellent electrical contact.

The photo of the male section shows where the barbs have scratched the metal on the way into the connector, with somewhat deeper impression at the final point due to the extra pressure from the compressive securing flange.
