Title: Lead frame material
Inventor: KARASHIMA AKIRA
IPC: H01L23/50
Filed: 1986-12-12
Abstract: PURPOSE:To improve positioning accuracy and transfer performance, by fixing prescribed corner parts of a lead frame directly to a lead frame outer part and linking the other corner parts with the lead frame outer part through bent linkage parts so as to reduce distortion due to heat stress. CONSTITUTION:Prescribed corner parts of a lead frame 8 are fixed directly on a lead frame outer part 2, and the other corner parts are linked with the lead frame outer part 2 through bent linkage parts 22 to 24. Therefore, even if a temperature difference occurs between the lead frame outer part 2 and the lead frame part 8 in a heat process, distortion stress is absorbed effectively by elastic deformation of the linkage parts 22 to 24. Hence, dimensional positioning accuracy of the lead frame part 8 itself is improved, and since no distortion occurs in a lead frame material 21 itself, transfer performance is upgraded so as to realize smooth transfer.

Then the adhesive agent layer is formed of a composite adhesive agent layer of outside adhesive agent layers 3, which are on both the sides 3 and not containing bubbles, and an intermediate adhesive agent layer 5 within which fine bubbles are included. A copper foil plated laminated sheet prepared in this manner is treated by a hot press for 30-90min. under terms of a heating temperature range of 180-200 deg.C and pressure of 30-50kg/cm<2>. Since the outside adhesive agent layer 3 and intermediate adhesive agent layer 5 are identical with each other in a resin composition, an interface of both the adhesive agent layers is almost welded at the time when the same is made into a C stage (cured). Since foaming progresses based on the core of a foaming agent, the foaming progresses in only the intermediate adhesive agent layer 5 comprised of an adhesive agent B and it does not happen that the bubbles do not come into contact with adhesive interface with the insulation board 1 or the metallic foil 2.

Abstract: PURPOSE:To perform highly accurate measurement at a low cost by correcting time series pulses for measurement based on the loss characteristic of an optical fiber for reference and back scattered light distribution of Rayleigh scattered light. CONSTITUTION:While the optical pulse of an optical pulse generator 5 is made incident to an optical fiber 34 through a demultiplexer 9 and optical switch 15, part of the pulse is branched to another optical fiber 36.

In addition, the back scattered light component in the scattered light generated in the fiber 34 returns to the demultiplexer 8 and the photodetector 40 outputs the component to a signal processor 42 as Rayleigh scattered light signals, time series pulse signals for measurement, etc. The processor 42 corrects the time series pulses by using the loss distance characteristic of the fiber 34 found from the Rayleigh scattered light distribution and a reference level passing through an optical fiber 22 for reference. In addition, the processor 42 uses the attenuation factor along the fiber 34 found from the Rayleigh scattering light distribution and for the correction of the time series pulses.
