Abstract

Abstract A PCMCIA card manufacturing process is disclosed, including the steps of (1) providing a top cover and a bottom cover made of a metal, preferably stainless steel, each of the top cover and bottom cover being provided with a plurality of hooks along two opposite lateral edges, (2) placing the top cover and bottom cover respectively into a first mold and a second mode for injection molding a first frame member on the top cover with the hooks of the top cover embedded in the first frame member and a second frame member on the bottom cover with the hooks of the bottom cover embedded in the second frame member, each of the first and second frame member being provided with at least one notch that match each other to define at least a connector slot, (3) disposing a circuit board between the first and second frame members with the connector thereof received within the connector slot, and (4) jointing the first and second members together, preferably by ultra sonic welding.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 290 words
A PCMCIA card manufacturing process comprising the following steps: (1) providing a first cover member and a second cover member which are identical members made of metal plates, each of the cover members being in the form of a rectangle having two lateral edges on each of which an edge flange is formed with a, plurality of inward facing hooks mounted thereto; (2) Placing the first and second cover members respectively into a first mold and a second mold to injection mold a first frame member and a second frame member onto the first and second cover members, each of the frame members having a U-shape with two legs separated a distance suitable to be accommodated between the two edge flanges of the associated cover member so as to have the hooks of the associated cover member embedded within the legs during the injection molding process to respectively define a first frame/cover sub-assembly and a second frame/cover sub-assembly, each of the U-shaped frame members comprising a bottom portion connecting between the two legs to form the U-shape and each of the bottom portions having at least a notch formed thereon, corresponding to each other; (3) Disposing a circuit board and associated electronic elements between the two sub-assemblies with at least a connector which is electrically connected to the circuit board received within the at least one notch formed on one of the sub-assemblies; and (4) Mating the first and second sub-assemblies to have the at least one notch that is formed on each of the bottom portions of the U-shaped frame members match each other to define at least a connector slot for receiving and retaining the connector therein and securing the two sub-assemblies together to form the PCMCIA card.
Claim 2
Dependent Claim 290 words
A PCMCIA card manufacturing process comprising the following steps: (1) providing a first cover member and a second cover member which are identical members made of metal plates, each of the cover members being in the form of a rectangle having two lateral edges on each of which an edge flange is formed with a, plurality of inward facing hooks mounted thereto; (2) Placing the first and second cover members respectively into a first mold and a second mold to injection mold a first frame member and a second frame member onto the first and second cover members, each of the frame members having a U-shape with two legs separated a distance suitable to be accommodated between the two edge flanges of the associated cover member so as to have the hooks of the associated cover member embedded within the legs during the injection molding process to respectively define a first frame/cover sub-assembly and a second frame/cover sub-assembly, each of the U-shaped frame members comprising a bottom portion connecting between the two legs to form the U-shape and each of the bottom portions having at least a notch formed thereon, corresponding to each other; (3) Disposing a circuit board and associated electronic elements between the two sub-assemblies with at least a connector which is electrically connected to the circuit board received within the at least one notch formed on one of the sub-assemblies; and (4) Mating the first and second sub-assemblies to have the at least one notch that is formed on each of the bottom portions of the U-shaped frame members match each other to define at least a connector slot for receiving and retaining the connector therein and securing the two sub-assemblies together to form the PCMCIA card.
Claim 3
Dependent Claim 31 words
The PCMCIA card manufacturing process as claimed in claim 1, wherein the securing of two sub-assemblies comprises the step of using ultra sonic welding process to joint the two sub-assemblies together.
Claim 4
Dependent Claim 18 words
The PCMCIA card manufacturing process as claimed in claim 1, wherein the metal plates comprise stainless steel plates.
Claim 5
Dependent Claim 58 words
The PCMCIA card manufacturing process as claimed in claim 1, wherein each of the cover members is provided with a recessed portion extending a substantial distance from a front end of the rectangle to a rear end along the lateral edges, the recessed portion being separated from the rear end and the two lateral edges of the rectangle.
Claim 6
Dependent Claim 58 words
The PCMCIA card manufacturing process as claimed in claim 4, wherein one of the first and the second frame members is provided with dowel pins and the other one of the first and second frame members is provided with engageable notches, the step of mating and securing the two sub-assemblies comprising engaging the dowel pins within the notches.
