Problems solved by technology

[0009] The existing problem of the wireless local area network card in the past is that since the non-volatile memory 56 is encapsulated by the covering resin 58, the production efficiency is low and the cost is high.
[0010] Moreover, since the transceiver circuit 54 and the baseband circuit 57 are respectively formed on both sides of the circuit board 51, there is a problem that although miniaturization can be realized, its negative effect is that various electrical components have to be installed on both sides. Low assembly efficiency and high cost

Embodiment Construction

[0022] Embodiment of the invention

[0023] The wireless local area network card of the present invention is described below, figure 1 It is a perspective view showing the outline of the wireless LAN card of the present invention, and now according to figure 1 , to describe the structure of the wireless LAN card of the present invention, the circuit board 1 made of laminated boards, etc. has a wiring pattern 2 formed on one surface 1a thereof, and a plurality of terminals for connectors are arranged side by side on both surfaces of one end. 3.

[0024] One face 1a of this circuit board 1 has the first area R1 and the second area R2 that the circuit board 1 is cut laterally and divided into two by a line S divided into two, and various electrical components ( Not shown), form the transceiver circuit 4 including the RF circuit, and install the nonvolatile memory 5 and various electrical parts (not shown) in the 2nd region R2, form the communication from the transceiver circu...

Abstract

To provide a cheap wireless LAN card having a good productivity and assembling performance. The wireless LAN card has a circuit board 1 having a plurality of formed terminals 3 for a connector, transmitting and receiving circuits 4 and a base-band circuit 6 which are formed on a surface side 1a of the circuit board 1, a non-volatile memory 5 mounted on the surface side 1a of the circuit board 1, and a box-type cover 8 for covering therewith the transmitting and receiving circuits 4. Since the non-volatile memory 5 is so provided near the transmitting and receiving circuits 4 as to cover the memory 5 and the circuits 4 with the single cover 8, the formation of a resin cover wherewith the wireless LAN card has been covered conventionally is so made unnecessary as to be able to provide the cheap wireless LAN card having a good workability.

Description

technical field [0001] The present invention relates to a wireless local area network card used when sending and receiving data in a wireless manner between electronic devices such as personal computers (PCs). Background technique [0002] Drawings of conventional wireless LAN cards will now be described. figure 2 It is a perspective view showing an outline of a conventional wireless LAN card, image 3 It is a perspective view showing a conventional wireless LAN card seen from the back. [0003] based on the following figure 2 , image 3 , indicating past wireless LAN cards. A circuit board 51 made of a laminate or the like has a wiring pattern 52 formed on both sides thereof, and a plurality of connector terminals 53 arranged side by side on both sides at one end thereof. [0004] On one surface side 51a of this circuit board 51, various electrical components (not shown) are mounted, and a transceiver circuit 54 including an RF circuit is formed. [0005] A box-shaped...
