摘要:
An adhesive composition including: a main component comprising a resin material, a solvent for dissolving said main component, and a filler added to said main component, wherein said filler has a particle size so as to make a concavo-convex depth of a surface of said adhesive composition equal to or less than 15 .mu.m after said adhesive composition is applied to an adherend and dried in order to evaporate said solvent before a thermocompression process. The present invention also discloses a semiconductor device using the adhesive composition, an adhering method using the adhesive composition and a method for producing a semiconductor device using the adhesive composition.
摘要:
An epoxy resin composition contains an epoxy resin as a substratal resin and incorporates therein a polyallylphenol curing agent. The composition may also contain a polyphenol compound. The epoxy resin may have a naphthalene skeleton. The epoxy resin composition may also include a blend of two or more epoxy resins.
摘要:
An epoxy resin composition for encapsulating semiconductors containing 5 to 50 parts by weight of a silicone-based flexibility imparting agent, 100 parts by weight of an epoxy resin containing at least two epoxy groups in one molecule thereof, 50 to 150 parts by weight of a curing resin including a phenolic resin, and 200 to 1,000 parts by weight of an inorganic filler.
摘要:
An apparatus for measuring the floating amount of the magnetic head comprising a single color light source such as laser, a rotating glass disk, a light scanner section, a photoelectric converter element, and an interference light strength computing section (or waveform memory section and computer section). Therefore, static behaviors such as pitch angle and balance of the magnetic head can be measured along with dynamic behaviors such as floating and frequency fluctuations thereof. Even when the floating amount of the magnetic head is extremely low, the measurement can be made accurately in a shorter time period with a high S/N ratio.
