Data.
As it has been described above, detector 5 is made up of multiple detector module 60 with said structure, then,
The manufacture method of detector module 60 is described with reference to Fig. 7～Fig. 9.
Fig. 7 shows that the first facial 81 to ceramic substrate 80 is assembled optical detection part 70 and applies bottom
Packing material 114, in drying machine 159, then carry out the optical detection part fixed work order hardened.
Fig. 8 shows that the second face 92 various electronic units of assembling at printed base plate 90 such as connect
Device 160 grade and multiple transacter 95 and after utilizing refluxing unit 179 to harden, coating
Underfill 170, the transacter then carrying out hardening in drying machine 189 configure work
Sequence.
Fig. 9 shows the unit group to the ceramic substrate 80 being assembled in the figure 7 with optical detection part 70
Fill flasher 61 unit and the printed base plate 90 utilizing connector for substrate 85 to be assembled in fig. 8
The assembling procedure electrically and being mechanically connected with ceramic substrate 80.
First, as it is shown in fig. 7, in the first facial 81 as the ceramic substrate 80 of first substrate
Print the conductive paste as conductive adhesive, first facial 81 is assembled optical detection part 70.And,
After first facial 81 and optical detection part 70 apply underfill 114, will be by ceramic base
The unit that plate 80 and optical detection part 70 are constituted puts into drying machine 159, such as with 150 DEG C of heating 4
Individual hour, conductive paste and underfill 114 is made to harden.After curing, will be by ceramic substrate 80
The unit constituted with optical detection part 70 is delivered to check that operation carries out the inspection specified.
On the other hand, as shown in Figure 8, print solder on the second face 92 of printed base plate 90,
Assemble such as adapter 160 or laser diode 161 and multiple transacter 95.And,
It is assembled with the printed base plate 90 of multiple transacter 95 grade in refluxing unit 179 such as with 250
DEG C heating 10 minutes, make solder reflow hardening and weld.Hereafter, to each transacter 95
Coating underfill 170, is then placed in drying machine 189, such as, add 30 points with 100 DEG C
Clock, thus makes underfill 170 harden.After curing, it is delivered to printed base plate 90 check
Operation carries out the inspection specified.
Finally, as it is shown in figure 9, scintillator cells 61 is carried out lift-launch group relative to optical detection part 70
Dress.And, utilize the connector for substrate 85 will be by ceramic substrate 80, scintillator cells 61 and optical detection part
70 unit 220 constituted electrically and are mechanically connected with printed base plate 90, complete detector 5
Detector module 60.
As it is shown on figure 3, the detector module 60 so manufactured is formed as with Z-direction along the X direction
Two-dimensional array, thus constitute the detector 5 of plane formula.And, by by this detector 5 and collimator
4 stackings, complete radiation detecting apparatus 50.
In relevant X ray CT device, believe from detector module to the simulation of transacter
Number transmission be to transmit via flexible wired components such as the transmission flexible base board of distance or flexible cables
's.Therefore, the length of arrangement wire of flexible wired component is longer, on the length of arrangement wire of flexible wired component
Electric capacity becomes big, is affected by from the microvibration of other parts or the electromagnetic field of power-supply system,
When analog-signal transitions is digital signal by transacter, can be by effect of noise.As
The countermeasure of this noise, example is configured with the shielding construction of ground wire pattern as used in the levels of signal routing,
But, even with this shielding construction, owing to the length of arrangement wire of flexible wired component is long, so still
So exist and wiring capability is become the problems such as big or magnetic field effect is little.
In contrast, in the present embodiment, as shown in Figure 4, there is multiple photodiode 71
Optical detection part 70 utilizes the first electric connection structure portion 110 to be installed on the first facial 81 of ceramic substrate 80.
Multiple transacters 95 are installed on the second face 92 of printed base plate 90.And, ceramic substrate
Second face 82 of 80 is via the connector for substrate 85 in the second electric connection structure portion 130 and printed base plate 90
First facial 91 electrically and mechanically connect.Therefore, each photodiode 71 is received with data
Physical distance between acquisition means is the least, is extremely difficult to the harmful effect by causing because of noise,
Transacter 95 can carry out converting analog signals at the signal of digital signal well
Reason.Accordingly, it is capable to access the image of high-quality.
