Referring to Fig. 7, an assembly welding dish is set on the printed circuit board (PCB) each address pin, wherein pad 51,52,53 is corresponding to address pin A0, and pad 51 is the common pad that is connected with address pin A0, and pad 52 is connected with power supply VCC, and pad 53 ground connection.In the time of need address pin A0 being changed to high level, welding resistance gets final product on pad 51,52, if need address pin A0 be changed to low level, then on pad 51,53, welds resistance.
Similarly, pad 54,55,56 is an assembly welding dish corresponding with address pin A1, and pad 54 is a common pad, is connected with address pin 54, and pad 55 is connected with power supply VCC, pad 56 ground connection.Pad 57,58,59 is an assembly welding dish corresponding with address pin A2, and pad 57 is a common pad, and A2 is connected with address pin, and pad 58 is connected with power supply VCC, pad 59 ground connection.And pad 52,55,58 connects through covering copper cash, and pad 53,56,59 also is to connect through covering copper cash.
It is thus clear that the pad data are less on the printed circuit board (PCB), simplify the design of printed circuit board (PCB), also reduce the area of printed circuit board (PCB), reduce the production cost of storage chip.
Consumable chip embodiment:
Present embodiment has a substrate, and this substrate is a printed circuit board (PCB), and the one side of substrate is provided with a plurality of electric contacts as communication unit, is used for being connected with the electric contact of ink-jet printer.Certainly, if be wireless telecommunications between ink-jet printer and the consumable chip, then communication unit is the antenna that is used for wireless telecommunications.
Another side at substrate is provided with the electronic module that is connected with electric contact; Electronic module have controller and a plurality of can be by the 24C series memory of controller access; Each memory is provided with at least one address pin; And substrate is provided with an assembly welding dish corresponding with each address pin, and each assembly welding dish comprises second pad of the common pad that is connected with address pin, first pad that is connected with power supply VCC and ground connection.When making substrate, can be according to the address assignment situation of each memory, an end of resistance is welded on the common pad, the other end is welded on first pad or second pad, thereby the high-low level of each address pin is set.
The setting of pad and pad distribution situation such as aforementioned storage chip embodiment are described on the substrate, repeat no more at this.
The consumable container of the utility model both can be mounted in the print cartridge on the ink-jet printer, also can be mounted in cartridge or carbon dust tube on laser printer or duplicator, facsimile machine, the all-in-one.
Print cartridge embodiment:
Present embodiment has a housing, and housing surrounds a cavity that holds ink, below cavity, is provided with the ink outlet port that is communicated with cavity, and the ink in the cavity can flow out through ink outlet port.And, on an outer wall of housing, a consumable chip according to the utility model the foregoing description is installed removably.
Cartridge embodiment:
Present embodiment has housing, and housing surrounds the cavity that holds carbon dust, and an end of cavity is provided with meal outlet.One as the described consumable chip of above-mentioned embodiment removably are installed on the outer wall of housing.
Certainly; The foregoing description only is the preferable embodiment of the utility model; During practical application more variation can also be arranged, for example, the 24C series memory only uses a pin as address pin; The high-low level that this pin only is set this moment can be realized the address of memory is provided with, and such change can realize the purpose of the utility model equally.
It is emphasized that at last the utility model is not limited to above-mentioned embodiment, also should be included in the protection domain of the utility model claim like the change of storage address pin, the variations such as change of welding resistance.
