PURPOSE:To braze surely to a ceramic substrate by a method wherein a material of at least one kind to act as a brazing material is plated on the necessary position on a ceramic substrate, and lead pins are set on the plated brazing material to be brazed in a furnace. CONSTITUTION:The prescribed positions on ceramics 1 are metalized 2, silver 8a of 8mum thickness and copper 8b of 2mum thickness are plated on plating 3 of the ceramic substrate 4 performed with electroless nickel plating 3 on the metalized parts 2 according to wet plating to obtain the brazing material 8. Then the lead pins 7 consisting of iron-nickel 42wt% are set on the plated brazing material 8 using a carbon jig 9, and brazing is performed in the conveyer furnace in the 850 deg.C hydrogen gas current. |
