The transponder unit is attached to the substrate for storing mounting process data, such as, the component manufacturer identification code, the number of missing components, and the number of faulty substrate position, before, during or after the mounting process. The stored process data can then be transmitted to a control unit that controls the component mounting apparatus wherein the data is processed and utilized during the mounting operation to enhance process quality control. ## Claims ### Claim 1 A method for mounting a component onto a printed circuit board of an electrical assembly comprising the steps of: providing an automatic component mounting unit, said automatic component mounting unit including a component mounting head member, a mounting control member, a mounting communication member and a mounting readout member; providing a data storage unit that is disposed on said printed circuit board; transporting said component to a predetermined position of said printed circuit board by moving said component mounting head member wherein said mounting control member controls said component onto said predetermined position by moving said component mounting head member wherein said mounting control member controls said mounting of said component; transmitting an amount of mounting process data from said mounting control member to said data storage unit via said mounting communication member; storing said amount of mounting process data within said data storage unit; transmitting said amount of mounting process data from said data storage unit to said mounting readout member wherein said amount of mounting process data is utilized during said mounting of said component. ### Claim 2 (depends on 1) A method according to claim 1, further comprising the steps of providing said automatic component mounting unit with a mounting magazine for supplying said automatic component mounting unit with a mounting magazine for supplying said automatic component mounting unit with a data storage unit and mounting said data storage unit onto said printed circuit board by moving said component mounting head member. ### Claim 3 (depends on 1) A method according to claim 1, further comprising the steps of providing a plurality of automatic component mounting units that are successively arranged in an assembly line manner wherein each of said automatic component mounting units that are successively arranged in an assembly line manner wherein each of said automatic component mounting units comprises a respective component mounting head member, a mounting control member, a mounting communication member and a mounting readout member, generating an amount of mounting process data at each of said automatic component mounting units during said mounting of said component and transmitting said amount of mounting process data to said data storage unit from said mounting control member via said mounting communication member for storing said amount of mounting process data that was generated at each of said automatic component mounting units during said mounting of said component. ### Claim 4 (depends on 3) A method according to claim 3, further comprising the steps of transmitting an amount of mounting process data from said data storage unit to said mounting communication member prior to said mounting of said component wherein said amount of mounting process data is then transmitted to and utilized by said mounting control member during said mounting of said component. ### Claim 5 (depends on 1) A method according to claim 1 wherein said printed circuit board further comprises a plurality of regions that each include a respective data storage unit and wherein each of said data storage units contains an amount of mounting process data that is specific to said respective region. ### Claim 6 (depends on 1) A method according to claim 1 wherein said amount of mounting process data comprises component manufacturer identification codes. ### Claim 7 (depends on 1) A method according to claim 1 wherein said amount of mounting process data comprises missing component information. ### Claim 8 (depends on 1) A method according to claim 1 wherein said amount of mounting process data comprises component inspection results. ### Claim 9 A manufacturing method comprising: transporting a component, via a component mounting head member of a component mounting unit, to a position on a printed circuit board, wherein the component mounting unit includes a communication member for communicating with a data storage unit disposed on the printed circuit board; mounting the component on the printed circuit board; and communicating information related to the mounting of the component, between the data storage unit and the communication member and between the communication member and the data storage unit, wherein the information related to the mounting of the component is transmitted for storage in the data storage unit. ### Claim 10 (depends on 9) The manufacturing method of claim 9, wherein the information related to the mounting of the component is received by the communication member prior to mounting the component on the printed circuit board. ### Claim 11 (depends on 9) The manufacturing method of claim 9, further comprising: transporting the printed circuit board to another component mounting unit; and transmitting information stored in the data storage unit to a communication member of the another component mounting unit prior to mounting another component on the printed circuit board. ### Claim 12 (depends on 9) The manufacturing method of claim 9, wherein stored information is maintained in the data storage unit attached to the printed circuit board. ### Claim 13 (depends on 9) The manufacturing method of claim 9, wherein each of a plurality of data storage units are attached to various regions of the printed circuit board. ### Claim 14 (depends on 9) The manufacturing method of claim 9, wherein mounting process information is stored in the data storage unit. ### Claim 15 (depends on 14) The manufacturing method of claim 14, further comprising: transporting the printed circuit board to another component mounting unit; and transmitting information stored in the data storage unit to a communication member of the another component mounting unit prior to mounting another component on the printed circuit board.
