It is used to electrically connect semiconductor elements on other electronic components or other packages on a substrate.

There are various ways to connect this type of package to a printed wiring board, but a typical example is to solder the connection terminals of the package directly to the surface of a conductive circuit formed on the printed wiring board. There are two types: one in which the package is attached, and the other in which the connection terminal of the package is inserted into a through hole formed on the printed wiring board side and the half 1B is attached. As examples of the former, so-called chip carriers and flat banks are known, and as examples of the latter, there are dual in-line packages (hereinafter abbreviated as DIP) and pin grid array packages (hereinafter simply abbreviated as P).
(abbreviated as GA) is known.

However, in recent years, semiconductor devices have become highly integrated, and as a result, this type of semiconductor device has become #F? a

There is a chip carrier as shown in No. 7151 or a flat package as shown in FIG. Although these packages have more input/output terminals compared to the above-mentioned DIP type packages, the number of required input/output terminals has increased to more than 200. Then, print distribution! ! The packaging density for one board decreases. This is because these packages allow input/output terminals to be arranged only on the outer periphery of the base material on which the semiconductor element is mounted.

このような入出力端子の数が200以上のものとなった
場合には、第9図に示したようなPGAが適している。
When the number of such input/output terminals is 200 or more, a PGA as shown in FIG. 9 is suitable.

However, such a PGA requires that the printed wiring board on which it is mounted has a large number of through-holes into which a large number of conductor pins on the back cage side are to be inserted. Not only does it require a large amount of through-hole processing on the board side,
The mounting density on the printed wiring board side is reduced by the large number of through holes.

In response to such problems and the increase in the density of semiconductor devices themselves as described above, surface mounting methods in which electronic components are directly connected to conductor circuits formed on the surface of a printed wiring board are increasing. This surface mount method eliminates the need to provide holes (through holes) on the printed wiring board side for inserting connection terminals for electronic components, and can form fine patterns (conductor circuits) using current technology, making it more efficient. This allows for flexible wiring. Therefore, this surface mounting method is likely to be applied not only to electronic components but also to packages having a large number of input/output terminals.

Conventionally, a so-called bat grid array type package, in which pins are removed from the above-mentioned PGA, has been proposed as a surface mount package having such a large number of input/output terminals and mounted on the surface of a printed wiring board. Such bat grid array type packages include those that are connected to the printed wiring board via solder bumps on the ceramic substrate, and those that have spring-shaped pins and connect them to the printed wiring board. .

However, for such surface mount packages, it is necessary that the physical and electrical characteristics of the package material and the material of the printed wiring board on which it is mounted match. Direct mounting on a printed wiring board consisting of a base has problems in terms of reliability. That is, due to the difference in expansion coefficient between the ceramic package and the plastic substrate, cracks occur at the joints of the solder bumps and spring-like pins. Also,
In this case, the difference in dielectric constant between the ceramic material and the plastic material is the cause of the impediment to speeding up the arithmetic processing of the semiconductor element on the package. moreover,
The surface element attachment pattern formed on the printed wiring board and the solder bonding pattern provided on the package must be formed and matched with extremely high precision. In particular, since ceramics have a large shrinkage during firing, it has been extremely difficult to achieve matching between a package formed of ceramics and a printed wiring board.
