       [0001]    The new type structure of an adapter card in the present invention is particular for the structural design and manufacturing process of a memory card in providing the storage and retrieval of the data and information. 
       BACKGROUND OF THE INVENTION 
       [0002]    Going with the increasing development and progress of the science and technology, the related electronic information product such as personal computer, MP3, digital camera, video recorder with camera and so forth of multimedia product become very popular, and the requirement or demand for the digital storage device in application of these said multimedia product from the consumers is also increased relatively. But, the specifications, size and apparatus of these said multimedia products are different either from product model to product model or form manufacturer to manufacturer. 
         [0003]    The digital storage devices of memory card and portable disk and so on already become the personal belongings of many computer users; Comparing with the diskette, the memory card and portable disk are not only small size, large storage capacity and quick storage/retrieval but also are hardly wetted and destroyed with quick read/write so that the memory card and portable disk become the indispensable accessory of the computer and the peripherals of the computer. 
         [0004]    For the portable disk, the equipped transmission interface of the universal serial bus (USB), which being generally used in the common existing computers and peripherals, possesses the plug-and-play (PnP) function without installation of additional drive program to most operating systems; Thereby, such design is not only easy in installation and running for the vendors but also a way of quick and simple operation and cheap price for the users. 
         [0005]    Contrarily, for the memory card, owing to each digital peripheral for every device model is only applied to limited specific specifications, they are always fabricated into variety of type and specification such as Smart Media Card, Secure Digital Card, Multi Media Card, Memory Stick Card, CF Card, XD Card and so forth to suit with digital devices such as digital camera, palm player, MP3, PDA and cellular phone and so forth in variety of model and brand; The possibility of exchange substitution is very low owing to neither is the same specifications and size nor is the same corresponding connector for each memory card; Hence, the consumer not only has to buy many different memory cards but also has often bought wrong memory card in useless condition with incompatible specification. 
         [0006]    Therefore, some businessmen simultaneously put up the universal serial bus (USB) and memory card interface with possible specifications of anyone in Secure Digital Card, Multi Media Card, CF Card and so on; although such structure can achieve the data and information transmission in dual interface manner, some existing drawbacks to be urgently improved are as below: 
         [0007]    For the fabricating process of memory card, a chip module including flash memory, control chip, passive component and so on together with a connected I/O contact connector at substrate front edge are mounted on the same substrate so as to construct the circuitry required, then the ultrasonic fusion or via mold-press, spot-glue-dispensing and so on are co-operated to closely stick which on the said substrate; If thermoplastic resin is used as manufacturing material, the production might be speeded up, but the produced memory card will become too hard in lack of suitable flexibility demanded and result in easy fracture under over pressure. Besides, because of the size and thickness of the memory card is different form that of the universal serial bus (USB), the memory card will be easily hooked by or withstand against the conducting terminal in the card connector during insertion into the card connector as height drop and unevenness in the shape and surface of the memory card; Hence, the deformation of the conducting terminal in the card connector will happen then seriously affect the precision and stability of the card insertion and conduction in between. 
         [0008]    Through long laborious study, research and experiment in addition to the relevant manufacturing experience background, the inventor of the present invention eventually develops and designs out the product structure and fabricating process of the present invention. 
       SUMMARY OF THE INVENTION 
       [0009]    Accordingly, the main object of the present invention is to provide a memory card fabricating process of not only quick production but also increasing the quality and yield. 
         [0010]    The further object of the present invention is to provide a memory card for storage and retrieval of the data and information with not only the specification and size in dual interface of both in conforming to the universal serial bus and memory card interface but also eliminating the risk in affecting the standard thickness and shape of the memory card. 
         [0011]    For achieving the objects aforesaid, the new type structure of an adapter card of the present invention combines both advantage of thermosetting and thermoplastic resin so as to let the dual interface adapter card of memory card and the USB have not only high production speed and yield but also easy assembly and better elasticity of flexibility without deformation or distortion and fracture; Additionally, by means of the contrivance in demountable separable block of temporal removal form or stacking on the universal serial bus (USB), the memory card can be made to have the shape and size of memory card or conform to the application specification of the USB.
