In a method for mounting an electronic part on a mounting substrate in that projection electrodes provided on the electronic part are welded by fusion to join connection terminals provided on the mounting substrate, the flux paste includes a base flux and metal grains having diameters smaller than the diameters of projection electrodes and having a thickness so as to form a space between the flux paste and the electronic part when the electronic part is mounted on the mounting substrate and the flux paste is arranged on the mounting substrate. A resin is sealed in the space formed between the electronic part and the mounting substrate after the projection electrodes are joined to the connection terminals.

A manufacturing method of a semiconductor device incorporating a passive element includes the steps as follows: a redistribution board forming step forms a redistribution board incorporating the passive element on a base board; a semiconductor element mounting step mounts at least one semiconductor element formed on an opposite side surface of the redistribution board with regard to the base board; a base board separating step separates the base board from the redistribution board and exposes the other surface of the redistribution board; a redistribution board mounting step mounts the redistribution board on a package board via electrode pads exposed from the other surface of the redistribution board.

A semiconductor device including a semiconductor chip sealed with an encapsulating resin. Columnar electrodes are connected to electrode pads of the semiconductor chip, and extend through the encapsulating resin. The columnar electrodes are made from bonding wires and include enlarged outer ends. Solder balls are arranged on the surface of the encapsulating resin and connected to the outer ends of the columnar electrodes. In another example, pin wires are formed by half-cutting bonding wires, bonding one end of each of the bonding wires, and cutting the bonding wires at the half-cut portions.

Graininess is suppressed while at the same time minimizing grayscale variations caused by inter-plane deviations. For this purpose, when a pixel is printed by M relative scans of a print head over a print medium or by a relative scans of M print heads over the print medium, M pieces of multivalued image data is created according to a division number or distribution ratio determined by a grayscale value of that pixel. The M pieces of multivalued image data are individually quantized and then the printing is performed according to the quantized pixel data. This process prevents dot generation delays and graininess from deteriorating in highlighted areas, thus realizing printed images highly robust against density variations.

When executing the gradation lowering processing to a data area in the lower side in multi-valued print data 403, an error generated by executing the gradation lowering processing to the data area in the lower side is stored in an information storage area 901B. On the other hand, the error thus distributed and stored is used for executing the gradation lowering processing to the data area “J” (Jth line) in multi-valued print data 404 relating to the next scan. In this way the error generated when executing the gradation lowering processing to the multi-valued print data is stored, which is used at the time of executing the gradation lowering processing to the multi-valued print data relating to the next scan. Therefore, the density is stored by receiving and delivering the error between the multi-valued print data in a scan unit.

Multi-valued image data stored in an input image buffer are read out for each time of scans, and the color space conversion and image distribution are performed to read multi-valued image data. The binarized result is sent to the print buffer and at the same time, is accumulated as the print information to execute processing of reflecting it to the image distribution processing of the next pass. It is possible to appropriately restrict the density fluctuation due to the print position shift between planes without providing pixels where dots are overlapped and printed more than necessary. With this, by accumulating the multi-valued image data at the stage of RGB in the input image buffer to read out data stored in input image buffer for executing processing, a capacity required for input image buffer does not change even if the number of the ink colors provided on the printing apparatus increases.
摘要:
The quantity processing is executed to data distributed for each color. Binary data obtained by this quantization processing are selected only in regard to a color generating print quantity information. Filtering processing is executed to the binary data of the selected color to generate the print quantity information. In the quantization processing for a second plane, data found by converting the print quantity information generated in the first plane processing into a minus value are added to the multi-valued data. In the quantization processing in the second plane added, the value of the multi-valued data is made small and in the quantity, probability that the multi-valued data become binary data printing the dots is made small. That is, a ratio where dots in the first plane and dots in the second plane overlap and are formed can be made small.

A spliced ink-jet head including head chips, each of which is capable of discharging inks of two or more colors, and which are spliced in a staggered manner which restrains the occurrence of splice streaks, white streaks caused by deflection at ends or uneven colors attributable to different landing orders of ink droplets in spliced portions of different colors when one-pass recording is carried out. The head chips is arranged such that, in a relationship between two adjoining head chips, at least one discharge port of one head chip and one discharge port of the other head chip for the same color tone ink in end portions overlap on a line in a recording material feeding direction, while discharge ports for different color tone inks do not overlap.
