After a printed circuit board layout design is finished, usually to the product that PCB layout slip-stick artist finishes be checked, find out and do not meet the wrong of designing requirement and make amendment.At this time to go under normal circumstances and seek different networks, as power supply,, distinctive signal, and between the information such as safety spacing.Traditional way is that the supervisory personnel analyzes domain and the visual inspection domain by rule of thumb, puts these information main points in order and finish a PCB layout to check usually and need to spend 1 to 2 hours.The problems referred to above have formed sizable puzzlement for the design efficiency of PCB industry, demand effective ways urgently and process, and can efficiently finish rapidly the inspection work of PCB.

Summary of the invention

In view of the above-mentioned problem that proposes, the invention provides the method for a kind of efficient inspection PCB, adopt this kind method to check that the efficient of PCB is higher than present method.

Technical scheme of the present invention is as follows:

The method of a kind of efficient inspection PCB may further comprise the steps:

Step 1 will comprise that the conventional layer of Top layer, Bottom layer is placed on wiring layer, and the color of Top layer is set to the first color, and the color of Bottom layer is set to the second color;

Step 2, newly-built a plurality of layers are other on mechanical layer, and the network that needs are outstanding is placed on the different layers of mechanical layer and does not go up, and the color of the first mechanical layer is set to the 3rd color, and all cablings of first network are set to the 3rd color simultaneously; The color of the second mechanical layer is made as the 4th color, and all cablings of second network are set to the 4th color simultaneously, by that analogy;

Described the first color, the second color, the 3rd color, the 4th color to the N color are respectively different colors.

Its further technical scheme is: if need outstanding the number networks more than or equal to 5, will comprise the similar network of part of power supply output U, V, W, unification is set to consolidated network, is placed on same machinery and does not go up layer by layer, adopts the same color.

Useful technique effect of the present invention is:

The present invention adopts color code technology, indicates to distinguish by in PCB main network signal being carried out different colours, with eye-catching presenting, thereby has saved the time that PCB checks, increases work efficiency.Check that according to present method a complete printed circuit board layout design needs about 1 to 2 hours, and according to method of the present invention shortened dramatically the time, can finish above-mentioned work about about half an hour.

The advantage that the present invention adds provides in the embodiment description partly below, and part will become obviously from the following description, or recognizes by practice of the present invention.

Description of drawings

Table one: each layer color setting

Layer title	Color	The network title
			Top	Red	?
Bottom	Blue	?
			Mechanical1	Color1	Special Net1
Mechanical2	Color2	Special Net2
			Mechanical3	Color3	Special Net3(such as U/V/W)
Mechanical4	Color4	Special Net4
			…	…	…

As shown in Table 1, conventional layer is placed on wiring layer such as Top, Bottom layer by former design, Top layer color is Red, Bottom layer color is Blue, and on mechanical layer newly-built a plurality of mechanical layers, the network that needs are outstanding is placed on the mechanical layer different layers and does not go up, different layers is not made as different colors, as the Mechanical1 color is made as Color1, all cablings (Copper Foil) of Net1 network are set to the Color1 color, the Mechanical2 color is made as Color2, all cablings (Copper Foil) of Net2 network is set to the Color2 color, by that analogy.
