Description
Technical field
The invention provides a kind of wiring board pad layout structure of signal filtration module welding, especially refer to that the narrow pad of plural signal single line on the wiring board and the wide pad of tap single line are for being dislocation and being spaced and being positioned at the difference innings mode of arranging, more groups solder joint can be set, the problem that the fraction defective of short circuit increased when effectively solution caused welding because of each weld spacing from approaching simultaneously under the wiring board finite width.
Background technology
Press, the now fast development of computer science and technology, and desktop computer or notebook computer general be present in each corner in the society, its Computer development trend also, speed strong towards calculation function reaches soon the little direction of volume and strides forward.Because during network communications technology is also rapidly flourish, and with people's life, study, work and lie fallow and bring another different brand-new boundary in the past into, make people more fervent and inseparable with the relation between the network.
Moreover, along with computer or notebook computer development trend, the connector that makes computer-internal also with significantly dwindle, but connector is in the computer downsizing, namely need consider the signal interference problem that its galvanomagnetic effect produces, and the reason that generally can affect the noise jamming of connector can be divided into two major parts haply, one is from the Electromagnetic Interference around the connector, its two interference that produces for connector inside, and because general RJ45 connector is used in digital communication mostly, just there is manufacturer to be provided with filtration module in network connector inside and solves above-mentioned disappearance, the external network signal that network connector can be received carries out the action of filtering, and the actual useful signal of reservation, in order to network signal is transferred to the external control circuit interface, after being converted into again string type transfer of data signal, just can in data handling system, carrying out signal and process.
Please consult simultaneously Fig. 9 and shown in Figure 10, be respectively vertical view and filtration module and the vertical view of wiring board after welding of known lines plate, find out by knowing among the figure, wherein the employed filtration module B of this network signal is generally by magnetic coil B1 and is consisted of, if this magnetic coil B1 will be welded on the wiring board A, namely need enough wiring board A width just to be enough to hold lower all solder joint A1, yet, the wire diameter of the general used copper cash B2 of magnetic coil B1 is 0.06-0.1mm, because the solder joint A1 solder side length on the wiring board A is about 0.8-3.0mm, and this width is about 0.4-1.2mm, so that need at least between two solder joint A1 solders side apart from the short-circuit conditions that could effectively avoid more than the 0.2mm causing because distance is too little when welding, so, general common wiring board A solder joint A1 layout type mostly comes layout in whole row's linear array mode, but this kind layout type requires wiring board A width must be large enough to hold the sum total of all solder joint A1 solders side, when if wiring board A width is restricted, its layout type namely can't be carried out.
In order effectively to solve the problem in the above-mentioned wiring board A width restriction, just there is the dealer to adopt the dislocation mode to come layout, please in conjunction with consulting Figure 11 and shown in Figure 12, be respectively vertical view and another known filtration module and the vertical view of wiring board after welding of another known lines plate, find out by knowing among the figure, it is more approaching that wherein this dislocation layout type can make the distance between each adjacent welds A1 solder side of wiring board A, approximately can effectively save the width demand more than 40%, in addition, the dealer who knows this field all knows, the one-sided copper cash B2 of each group magnetic coil B1 includes two single lines and one group of twisted wire usually, but twisted wire is the situation that two single line modes weld to avoid failure welding by scattering again often, wherein twisted wire is called tap, this tap connects for short circuit in design, if yet when adopting dislocation mode layout to reduce requiring of wiring board A width, just can be because of also having a copper cash B2 in each the solder joint A1 spacing on the wiring board A, cause the fraction defective of short circuit is increased, and coming than the linear array layout type must be high, then remains to be engaged in this journey dealer and redesigns effectively and solved.
