Abstract:
PROBLEM TO BE SOLVED: To provide a heat-dissipating resin composition having excellent heat-dissipating characteristic, which is most suitably used as a composition for a solder resist in particular. SOLUTION: The heat-dissipating resin composition contains matrix resin and a filler. The filler includes nanofiber-type aluminum nitride. For this reason, the heat-dissipating resin composition is given a high-level thermal conductivity by the nanofiber-type aluminum nitride, thereby exerting excellent heat-dissipating characteristic.

Abstract:
PROBLEM TO BE SOLVED: To provide a process for producing a wiring board in which high precision machining can be carried out without causing misregistration or deformation by performing such machining as formation of conductor wiring or mounting of a component on a wiring board substrate while holding the wiring board substrate stably on a wiring board substrate holder, and occurrence of deformation due to undue tensile stress can be suppressed when the wiring board substrate is stripped from the wiring board substrate holder. SOLUTION: A wiring board substrate is machined under a state where it is bonded to the organic layer of a wiring board substrate holder where the organic layer for holding the wiring board substrate is bonded to a holder body. Subsequently, the wiring board substrate is stripped from the organic layer under a state where stripping strength at the interface of the organic layer and the wiring board substrate is reduced by infiltrating the interface with liquid exhibiting affinity to the organic layer.
