  • Process for varnishing a card equipped with connecting pins and card obtained in this way
    Patent number: 4360559
    Abstract: The process makes it possible to increase the electrical insulation and corrosion protection permitting the deposition of a varnish over the entire card, including the weld areas of pins. Prior to varnishing the process consists of placing protective sheets perforated at the location of the pins and of protecting the external parts of the pins by means of a deposit of a soap-based solution. The varnish further deposited on the faces of card does not adhere to the parts of the pins protected in this way. After drying the varnish it is merely necessary to clean the pins with hot water and by brushing to remove the protective deposit.
