PROCESS FOR PRODUCING MODULAR SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a process for producing a modular substrate capable of obtaining a highly reliable modular substrate at a low cost.

SOLUTION: On a ceramic substrate 1 provided with splitting grooves 2 for partitioning a plurality of modules each mounting a component 3, a resin layer 4 of curing resin is formed on the substantially entire surface. After the resin layer 4 is cured temporarily, incising grooves 5 are formed from the surface of a resin layer 4a to the splitting groove 2 in correspondence with the splitting groove 2 and then the resin layer 4a is cured actually. Thereafter, the ceramic substrate 1 is divided into individual modules by the splitting groove 2 and the incising groove 5.
