Abstract

PURPOSE:To obtain sealed electronic parts highly stable under high pressure vapor, by using a polyphenylene sulfide resin with a water soluble electrolyte content of 100ppm or less in sealing the electronic parts. CONSTITUTION:It is common that a thermoplastic resin consists of polyphenylene sulfide contains considerable electrolytes. Therefore, the content of the electrolytes. Therefore, the content of the electrolytes is reduced to 100ppm or less after washing by demineralized water, as the thermoplastic resin cannot be used in an original condition. The warm of demineralized water effects the reduction of an electrolyte content. Therefore, boiling water or pressure hot water is used. If polyphenylene sulfide is left in a powder condition of 100 mesh or less, a contact area to the demineralized water will be increased and the effect of eliminating electrolytes will further be increased. This method reduces the content of electrolytes and the coating and sealing is applied to electronic parts by using such a resin.
