Abstract
The utility model provides a set top box circuit board which comprises a printed circuit board and a decoding chip which are electrically connected. A plurality of FLASH package chips which are electrically connected are disposed on the printed circuit board. By the routing manner during wiring, 2-3 kinds of pin positions for FLASH packaging are reserved, all pins are combined to be connected to pins appointed by the chips, and accordingly fluctuation of FLASH markets can be left out, a single product uses a single PCB (printed circuit board), inventory risk is lowered, and production efficiency is increased.
Description
Technical field
The utility model relates to a kind of circuit board, particularly a kind of set-top box circuit board.
Background technology
Printed substrate is one of vitals of electronics industry.Printed substrate can provide mechanical support fixing, assembling for electronic devices and components, can realize the electrical connection between electronic devices and components.In addition, all be printed on numbering and some figures of element on printed substrate, this provides convenience for element plug-in mounting, inspection, maintenance.Every kind of electronic equipment almost littlely arrives greatly computer to electronic watch, calculator, communication electronic equipment, and military armament systems as long as the electronic devices and components such as integrated circuit are arranged, for the electric interconnection between them, all will use printed substrate.
FLASH is one of core components and parts in digital TV set-top box, and the producer that produces in the market flash is many, and external form, size, and the distributions of PIN pin etc. are not identical, do not possess compatibility.
Flash belongs to fluctuation larger market, affect production thereby the flash of certain model is easy to occur problem in short supply, and present more common solution is the flash that first gets ready the goods, then comes lower pcb board order.
The utility model content
The utility model proposes a kind of set-top box circuit board, solved the defective that set-top box circuit board in the prior art can not be supported the FLASH of Multiple Type; The utility model is simple in structure, can support the FLASH packaged chip of Multiple Type.
The technical solution of the utility model is achieved in that
A kind of set-top box circuit board, it comprises printed substrate and decoding chip;
Described printed substrate and described decoding chip are electrically connected, and described printed substrate is provided with a plurality of FLASH packaged chips;
A plurality of described FLASH packaged chips are electrically connected mutually.
Further, described FLASH packaged chip comprises a FLASH packaged chip and the 2nd FLASH packaged chip.
Further, a described FLASH packaged chip comprises 16 pins, and described the 2nd FLASH packaged chip comprises eight pins, and the pin on described the 2nd FLASH packaged chip respectively the pin corresponding with a described FLASH packaged chip be electrically connected.
Further, described FLASH packaged chip comprises a FLASH packaged chip, the 2nd FLASH packaged chip and the 3rd FLASH packaged chip.
Further, include a plurality of pins on a described FLASH packaged chip, described the 2nd FLASH packaged chip and described the 3rd FLASH packaged chip, and a described FLASH packaged chip, described the 2nd FLASH packaged chip, described the 3rd corresponding pin of FLASH packaged chip are electrically connected mutually.
The utility model is when PCB layout, mode by cabling, reserve the pin positions of 2-3 kind FLASH encapsulation on pcb board, and with all pins also together, be connected into the pin of chip appointment, therefore can not consider the fluctuation in FLASH market, single product adopts single PCB wiring board, reduce inventory risk, enhance productivity.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the utility model set-top box circuit board;
Fig. 2 is the schematic diagram of the utility model printed substrate.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, a kind of set-top box circuit board 1, it comprises printed substrate 2 and decoding chip 3; Described printed substrate 2 is electrically connected with described decoding chip 3, and described printed substrate 2 is provided with a plurality of FLASH packaged chips (not shown); A plurality of described FLASH packaged chips are electrically connected mutually.
Further, described FLASH packaged chip comprises a FLASH packaged chip 41 and the 2nd FLASH packaged chip 42.
Further, a described FLASH packaged chip 41 comprises 16 pins 5, described the 2nd FLASH packaged chip 42 comprises eight pins 6, and the pin on described the 2nd FLASH packaged chip 42 respectively the pin corresponding with a described FLASH packaged chip 41 be electrically connected.In the utility model, clock signal pin CLK, the data output connecting pin DO of a FLASH packaged chip and the 2nd FLASH packaged chip, data input pin DI, chip selection pin CS, power supply output connecting pin VCC, maintenance functional pin HOLD, ground connection pin VSS and the corresponding electric connection of write-protect pin WP.
Further, described FLASH packaged chip comprises a FLASH packaged chip 41, the 2nd FLASH packaged chip 42 and the 3rd FLASH packaged chip (not shown).
Further, include a plurality of pins (not shown) on a described FLASH packaged chip 41, described the 2nd FLASH packaged chip 42 and described the 3rd FLASH packaged chip, and a described FLASH packaged chip, described the 2nd FLASH packaged chip, described the 3rd corresponding pin of FLASH packaged chip are electrically connected mutually.
Certainly, the staff can select the FLASH packaged chip on printed substrate is arranged to other quantity according to demand, the FLASH packaged chip that only need reach a plurality of functions is integrated on a printed substrate, in the time of need to using what function, the user only needs the FLASH packaged chip pin conducting of correspondence is got final product.
The utility model is when PCB layout, mode by cabling, reserve the pin positions of 2-3 kind FLASH encapsulation on pcb board, and with all pins also together, be connected into the pin of chip appointment, therefore can not consider the fluctuation in FLASH market, single product adopts single PCB wiring board, reduce inventory risk, enhance productivity.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
