Technical field
The present invention relates to a kind of method with the auxiliary assembled printed circuit boards of computing machine, and particularly relevant for a kind of method of putting circuit component.
Background technology
In the design process of printed circuit board (PCB), previous topological design is one of considerable work, wherein use the operation of computer drawing printed circuit board (PCB) mainly to be divided into two parts again, one is cloth spare processing (placement) operation of front, and another is the configuration operation of back.
In the cloth spare processing procedure of computer system, the staff is that the wiring diagram according to circuit board processes.And a wiring diagram has many circuit components, and each circuit component has the electric capacity of many correspondences again.These electric capacity mainly are to be used in filter current or electric wave, avoid exceeding circuit component portative electric current of institute or electric wave and damage circuit component.And be used in the electric capacity of filter current or electric wave purposes, its putting position there is no clear and definite standard, if the current circuit that designs on the wiring diagram is near the pin position of circuit component, then put principle and place electric capacity in the mode of contiguous this pin position, and do not add timing on the wiring diagram, then put the mode of principle, place the circuit component that can have influence on adjacent to electric current or electric wave to disperse.
Yet, do not having clearly when putting standard, staff's way is to click circuit component in computer system at present.At this moment, system can show electric current the circuit of process, and with manual type with the electric capacity of many filter current or electric wave place electric current near the circuit component of process.When in case the electric capacity quantity that need put increases, the also relative growth of staff's spended time relatively.
Therefore, the industry that how to solve is with time-consuming manual type, with the electric capacity of many filter current or electric wave be placed on be adjacent to electric current the circuit component of process, be the industry problem demanding prompt solution.
Summary of the invention
Plugging in artificial mode of known electric capacity finished, and not only time and effort consuming makes that also speed of production is slow, is the speed of quickening to produce, and the invention provides a kind of method of putting circuit component.
The method of the disclosed putting circuit component of the present invention is applied to auxiliary assembled printed circuit boards.The method of putting circuit component of the present invention comprises the following steps:
Read the line file of walking of the circuit layout of printed circuit board (PCB) and corresponding circuits Butut, then represent the element pattern of first circuit component in the selecting circuit Butut, element title according to the element pattern of choosing, in walking line file, find out and correspond in the element title, at least one second circuit element with set capacitance, and in circuit layout corresponding to another surperficial position of the printed circuit board (PCB) at the element pattern place of first circuit component, the capacity cell pattern of second circuit element is represented in configuration, and forms interconnective at least one cabling pattern.
Wherein, in walking line file, find out the second circuit element that corresponds to first circuit component with set capacitance, can comprise the following steps: element title, in walking line file, find out the pin title of all counter element titles according to the element pattern of choosing.Then, with the pin title of all counter element titles, in walking line file, find out at least one second circuit element of all corresponding pin titles, and screen in all second circuit elements of finding out, have the second circuit element of set capacitance.
Wherein, the capacity cell pattern that the second circuit element is represented in configuration can comprise the following steps: to find out the coordinate of each pin in circuit layout according to each pin title of finding out in walking line file in printed circuit board (PCB).According to the coordinate of the pairing pin of each first circuit component, dispose the coordinate of capacity cell pattern, and between the pin of each capacity cell pattern and correspondence, form an interconnective cabling pattern adjacent to pin.
Wherein, have the second circuit element of set capacitance, its set capacitance can be 0.01uf (microfarad).
In sum, method according to putting circuit component of the present invention, can be in order to the circuit layout of automatic draw PCB, kind by the identification circuit element, automatically the electric capacity of circuit component correspondence is furnished in correct position, the cloth spare program that dullness is loaded down with trivial details is carried out by computing machine, to avoid waste of manpower resource, improves speed of production and increases production capacity.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Description of drawings
Fig. 1 is the process flow diagram of method of the putting circuit component of the embodiment of the invention;
Fig. 2 is that the configuration of the embodiment of the invention represents the capacity cell pattern of second circuit element in the process flow diagram of printed circuit board (PCB).
Embodiment
Please refer to Fig. 1, as shown be the process flow diagram of the method for putting circuit component of the present invention.The method of putting circuit component comprises the following steps: that default one walks line file (as net file), and this document comprises the cabling title that element title, element number, interelement neighbouring relations, element are connected with interelement at least, and this cabling is numbered.
That reads the circuit layout of printed circuit board (PCB) and corresponding circuits Butut walks line file (step 100), represent the element pattern (step 200) of first circuit component in the selecting circuit Butut, according to the element title of the element pattern of choosing (for example, U1), in walking line file, find out the pin title (for example, U1-36 U1-12 U1-20) (step 300) of all counter element titles.Then, with the pin title of all counter element titles, in walking line file, find out at least one second circuit element (for example, PWR-C_20-5-5_20-5-5) (step 400) of all corresponding pin titles.Screen in all second circuit elements of finding out, second circuit element (step 500) with 0.01uf capacitance, and in circuit layout corresponding to another surperficial position of the printed circuit board (PCB) at the element pattern place of first circuit component, the capacity cell pattern (step 600) of second circuit element is represented in configuration, and forms interconnective at least one cabling pattern (step 700).
Please continue with reference to Fig. 2, as shown being configuration represents the capacity cell pattern of second circuit element in the process flow diagram of printed circuit board (PCB), its step comprises: according to each pin title of finding out, in walking line file, find out the coordinate (step 610) of each pin in circuit layout, coordinate according to the pairing pin of each circuit component, dispose the coordinate (step 620) of capacity cell pattern, and between the pin of each capacity cell pattern and correspondence, form an interconnective cabling pattern (step 630) adjacent to pin.
