Silver Paste Through Hole Printed Wiring Board

Kyosha accomplishes this highly reliable wiring board by employing low migration conductive paste coupled with our excellent manufacturing capabilities. The silver paste through hole printed wiring board is a double sided printed wiring board in which the front and back side of the wiring are connected by through holes filled with silver paste.

Characteristics

It has a great cost performance and is usually used when double sided copper plated wiring boards are too expensive and single sided wiring boards are too difficult to integrate all the wirings into.
(Example: televisions, faxes, telephones, audio devices, printers,)
