Chip-card blank
What the present invention relates to is chip-card blank according to the preamble of claim 1, that is to say that chip-card blank has one and pre-determines the groove that is used to admit chip module.
In Fig. 5 a, point out the cross-sectional view strength of such chip-card blank, in Fig. 5 b, pointed out the planimetric map of such chip card.
In figure, this chip-card blank has been described with mark mark 1.Have a groove 10 thereon on the surface, on this groove, also have a deep trouth 20.
In the groove 10 that so forms, can insert a chip module shown in Fig. 6.
Chip module 30 has a holder part 31, and a chip 32 and the stiffening frame 33 around chip are installed in the above.
The groove 10 of chip-card blank 1 and chip module 30 are controlled dimensionally mutually so to be fit to, whole chip module 30 is so to determine the position in groove, be that it mainly flushes making with the external upper of chip-card blank 1 at the chip 32 of the upper surface of the holder part 31 of chip module 30 and stiffening frame 33, chip 32 and stiffening frame 33 are crouched in the deep trouth of groove 10.
Bonding by chip-card blank and chip module, the assigned address that is fit in chip-card blank 1 inside carries out the fixing of chip module 30.
Studies show that under the bend loading situation according to ISO/IEC 7816-1, so the chip card major part that produces is harder, has less bending strength in addition, therefore perhaps may produce the usability of chip card and/or the problem of endurance quality.
Particularly when the chip card that should continue to use, this may not be a unessential shortcoming.
Therefore task of the present invention is, so improves the chip-card blank according to the preamble of claim 1, by simple method and can accurately produce one and have than soft with than the chip card of high-flexural strength.
Solved this task according to the present invention by feature at the characteristic of claim 1.
Therefore, pre-determine an extra large nurse device (Hemmanordnung) that centers on the inside grooves zone wholly or in part, in this interior zone, hinders the alite paste diffusion in the inside of groove.
Can keep the little Pasting surface of having indicated in addition on the Pasting surface of groove perimeter limited chip card body and chip module by pre-determining this mark.Got rid of the stickup of the stiffening frame and the chip-card blank of chip and/or chip module especially.

The viewgraph of cross-section of Fig. 5 a traditional die module,
The planimetric map of Fig. 5 b traditional die module and
Fig. 6 can insert the viewgraph of cross-section of the chip module of chip-card blank.
The same with the chip-card blank of introducing among Fig. 5, below with reference to Fig. 1 to 4 the suitable embodiments of the invention of chip-card blank 1 of explanation are had a groove 10 in the surface thereon, this groove itself also has a deep trouth 20.
With the same on traditional chip-card blank, be fit on the chip-card blank of the present invention, the groove 10 of chip-card blank 1 and chip module 30 are controlled dimensionally so suitable, whole chip module is so to determine the position in groove 10, be that it mainly flushes making with the upper surface of chip-card blank at the chip 32 of the upper surface of the holder part 31 of chip module and stiffening frame 33, chip 32 and stiffening frame 33 are crouched in the deep trouth of groove 10.
Different with traditional chip-card blank, be fit to chip-card blank of the present invention and have an extra large nurse device that groove 10 interior zones are separated with groove 10 perimeters in the inside of groove 10, it hinders alite paste and is diffused into its internal range from the groove perimeter.
In all version, deep trouth 20 is completely contained in the inside grooves zone of having mentioned, that is to say extra large nurse device around deep trouth 20, to this, chooses at random the spacing between deep trouth and the extra large nurse device that centers on, and perhaps may change the position.
At first extra large nurse device fully and consistently, that is to say the interior zone of the groove that interruptedly is not looped around the agent blocking-up that is stuck.
Yet, according to situation separately, if extra large nurse device only along around the be stuck interior zone of groove of agent blocking-up of a part and/or interruptedly be centered around perhaps be enough.
Can prevent that to the blocking-up in inside grooves zone the deep trouth of chip and/or reinforced liner and groove is bonding by alite paste.Therefore under the situation of the structure of the corresponding large-size of deep trouth of groove, this unit can make chip unhinderedly move mutually with relative unit when bending.
Below with reference to Fig. 1 to 4 the different possibilities of the planform of preferred extra large nurse device at present are described.
Extra large nurse device according to Fig. 1 comprises a protuberance 11 that is looped around the inside grooves zone from groove 10 bottom protrusion.
Insert at chip module 30 under the situation of chip-card blank 1, this protuberance 11 forms the partition that the inside grooves zone more or less seals with the perimeter with holder part 31 actings in conjunction of chip module.Therefore the alite paste that is coated with in the groove perimeter can neither move also not because the squeeze pressure that exists in the perimeter of groove enters into the interior zone of groove by normal flowing; Therefore chip-card blank and the chip module part that can be connected by alite paste not only dimensionally but also be limited to put perimeter at groove on the throne.
It is the cross section of semi-circular shape substantially that the shape of this protuberance is not constrained to shown in Figure 1; Opposite this cross section can constitute other shape arbitrarily, and is for example leg-of-mutton, rectangle, labyrinth shape or this class.
The ratio of each several part shown in Figure 1 also can change arbitrarily.
Shown in Fig. 4 a, this protuberance 11 along the periphery of groove 10 perimeters fully and not interruptedly around the interior zone of groove 10.The inside grooves zone around also realizing that its absolute dimension and division ratio can be determined as required pre-determining under the situation of interruption; For example, shown in Fig. 4 b, though this protuberance 11 fully around the interior zone of groove 10, only is that pointwise forms substantially.
Figure 2 shows that the variant of the version of extra large nurse device shown in Figure 1.
Though relate to a protuberance in the extra large nurse device shown in Fig. 2, different with protuberance shown in Figure 1, it is a coarse protuberance 12, for example produces by wearing and tearing or this class form.
Although one coarse surface like this-sensuously this is not that protuberance-obstruction alite paste spreads by him in tradition, and can guarantee equally that therefore the interior zone of groove and alite paste keep isolating.
Shown in Fig. 4 a, this coarse protuberance 12 can be along the periphery of groove 10 perimeters fully and not interruptedly around the interior zone of groove 10.The inside grooves zone around also realizing that its absolute dimension and division ratio can be determined as required pre-determining under the situation of interruption; For example, shown in Fig. 4 b, though this coarse protuberance 12 fully around the interior zone of groove 10, only is that pointwise forms substantially.
Also can predetermined other possibility, not only pre-determine rough surface, and can completely or partially expand in the groove perimeter at the interior zone of groove and the limit section between the groove perimeter.
Rough surface also can pre-determine method as a supplement on the protuberance 11 according to Fig. 1.
Another version of extra large nurse device has been described, and this form comprises one at the deep trouth 13 of groove 10 bottom part ring around the ditch shape of groove perimeter in Fig. 3.
Deep trouth 13 forms a settling region, is diffused into the alite paste in concave interior zone from recessed perimeter in this settling region inner accumulated.Therefore the alite paste that is coated with in the groove perimeter can neither move also not because the squeeze pressure that exists in the perimeter of groove enters into the interior zone of groove by normal flowing; Therefore chip-card blank and the chip module part that can be connected by alite paste not only dimensionally but also be limited to put perimeter at groove on the throne.
It is the cross section of semi-circular shape substantially that the shape of this deep trouth 13 is not constrained to shown in Figure 3; Opposite this cross section can form other shape arbitrarily, and is for example leg-of-mutton, rectangle, labyrinth shape or this class.
The ratio of each several part shown in Figure 3 also can change arbitrarily.
Shown in Fig. 4 a, this deep trouth 13 along the periphery of groove 10 perimeters fully and not interruptedly around the interior zone of groove 10.The inside grooves zone around also realizing that its absolute dimension and division ratio can be determined as required pre-determining under the situation of interruption; For example, shown in Fig. 4 b, though this deep trouth 13 fully around the interior zone of groove 10, only is that pointwise forms substantially.
In order to reach special effect, the version of the extra large nurse device suitable of the present invention that has illustrated about Fig. 1 to 3 is alternate combinations piecemeal also.
