Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To easily and surely perform masking and removal of masking after process by coating a masking ink on a gold plated part for forming a setting protection film before performing a solder leveler process. SOLUTION: A copper plating 3 is performed on the front and rear surfaces of a copper plating laminated plate 1 and on an inside wall surface of an opened through hole 2. Then, a circuit 4 is formed at an outside layer with a solder resist 5 formed at the circuit 4. Further, after a part of the outside layer where gold plating 7 is not performed is masked with a dry film 6, the gold plating 7 is performed with the outside layer to remove the dry film 6. Then, a masking ink whose main component is a vinyl chloride derivative is coated on the gold plating part 7 by screen printing, to form a setting protection film 8. Here, a solder leveler process is performed with a molten solder to form a solder coat 9, and the setting protective film 8 is once peeled off to provide a printed wiring board, where the gold plating part 7 has been exposed.

Next, the data of y(h) and sampling periods of u(h), u'(h), u''(h),... are inputted and a parameter estimating device 11 estimates the coefficient of a multi-input one-output ARMA model according to an on-line method of least squares. By this method, because a vector A<-1>(Z)B0<-1>(Z) shows the pulse transfer function of a control object, this function is inputted to a transfer function converting operator 12. The operator 12 inputs this function and a sampling cycle to convert the same to the transfer function of a continuous time.

Abstract: PURPOSE:To attain to enhance the accuracy in the quantitative analysis of the element of a non-uniform specimen, by performing the quantification of an element at every uniform partial phase with respect to the nonuniform specimen and calculating the average of the whole. CONSTITUTION:For example, in the surface structure of a nonuniform specimen consistnig of elements A-D, a code alpha forms a uniform phase in a substrate part and codes beta, gamma, epsilonare different in the compositional ratio of elements from the substrate part alpha but each of said codes themselves has a uniform phase and the partial phase distributed in the alpha-phase of the substrate. The surface of this specimen is scanned along lines 1, 2 by electron beam and the detection intensity of characteristic X-rays of each of the elements A-D is taken in a memory. From the intensity data stored at every characteristic X-rays, a hystrogram showing the appearance frequency of each intensity is formed. Corresponding peak groups are detected between tthe hystograms and the intensities of characteristic X-rays of the elements A-D at every peak group are determined from the heights of the corresponding peak groups. Then, the correcting calculation in the quantification of elements is performed at every peak group from the ratio of the intensities and the correction result is multiplied by a wt. at every peak group and weighted mean is taken to calculate the average elemental composition of the whole of the specimen with good accuracy.
