This creation is about an alloy resistance structure, especially a series array type alloy sheet structure of alloy resistance, which includes at least one alloy resistance wiring circuit in a matrix block planned on an alloy sheet, and in the alloy resistance A series array of alloy resistance regions including a plurality of alloy resistance regions spaced adjacent to each other is arranged in the layout loop.

Check that traditional surface mount chip resistors are generally manufactured by a thick film printing process, which is mainly formed on a selected ceramic substrate through a sequence of printing, laser trimming, copper terminals, and electroplating processes on the ceramic substrate. Resistors needed. In another type of resistor, alloy resistors are widely used.

Although alloy resistors have their specific advantages, there are still some technical problems in the processing of alloy resistors. For example, in terms of material utilization, the current technology due to poor planning and layout makes expensive alloy plates high in wear rate, unable to achieve optimal area utilization, and thus unable to achieve the purpose of saving material costs.

Furthermore, poor planning and layout often fail to increase the density of component placement of alloy resistors. In the process of component testing after the completion of the manufacturing process, it is often limited, so that the production efficiency and packaging efficiency cannot be improved.

For this reason, the main purpose of this creation is to provide a serial array type alloy sheet structure of alloy resistors in order to overcome the above-mentioned shortcomings of the current technology.

The technical means used in this creation is that each matrix block of a plurality of matrix blocks planned on an alloy plate includes a flushing area and a plurality of alloy resistance wiring circuits that are parallel to each other and separated by a distance or at least An alloy resistance arrangement loop, each of the alloy resistance arrangement loops, is arranged with a series array of alloy resistance zones, and the series array of alloy resistance zones includes a plurality of alloy resistance zones spaced and adjacent to each other. Each of the alloy resistance areas is then encapsulated by a package body.

Preferably, one end of each of the alloy resistance wiring circuits is connected to the alloy sheet at a first flushed side edge of the flushed area, and the other end is connected to a second flushed area toward the flushed area. The direction of the side edge extends to form a free end pattern, and is separated from the second flushed side edge by a distance.

In terms of effect, since this creation is in the process of alloy resistance, a plurality of alloy resistance wiring circuits or at least one alloy resistance wiring circuit that are parallel to each other and separated by a distance are formed on the alloy plate, and then a circuit is laid on each alloy resistance. Zhongcai serial array layout of multiple resistance zones of the alloy adjacent to each other can achieve higher area utilization of alloy plates, save material costs, increase the density of component layout, facilitate single-unit testing, and improve production efficiency And packaging efficiency.

The specific technology used in this creation will be further explained by the following embodiments and accompanying drawings.

Refer to Figures 1 and 2 at the same time. First, an extended type alloy plate 1 (shown in Figure 1) is prepared with nickel, chromium alloy or other materials suitable for alloy resistance, and then the effective area of the alloy plate 1 is planned A plurality of matrix blocks 2 (for example, the 2x6 matrix blocks 2 shown in FIG. 2) separated by a distance from each other are generated.

Referring to Fig. 3, in each matrix block 2 of the plurality of matrix blocks planned on the alloy plate 1, according to the size and resistance value of the required alloy resistance finished product, the flushing area 21 and the plurality of each other are planned Circuits 31, 32, 33 are arranged in parallel and separated by an interval of alloy resistors (as shown in Fig. 2).

Referring to FIG. 4, in the subsequent process, after the punched area 21 is punched out by the punching process, a first punched side edge 22 and a second punched side edge are formed in each matrix block 2. 23. At the same time, at least one alloy resistance wiring circuit 31 or a plurality of alloy resistance wiring circuits 31, 32, 33 that are parallel to each other and separated by an interval are left.

Also refer to Figures 5-7. Figure 5 shows an enlarged view of several alloy resistor wiring circuits formed in one of the matrix blocks 2 in Figure 4, Figure 6 shows a cross-sectional view of the AA section in Figure 5, and Figure 5 7 shows a cross-sectional view of the BB section in Figure 5. As shown in the figure, one end (the left end) of each alloy resistance wiring circuit 31, 32, 33 is connected to the unpunched alloy plate 1 at the first punched side edge 22, and the other end (the right end) is It extends in the direction of the second punched side edge 23 to form a free end type, and is separated from the second punched side edge 23 of the alloy sheet 1 by a distance. Such a layout pattern helps release the stress of the sheet and prevents possible forming deformation problems.

Each of the alloy resistor wiring circuits 31, 32, 33 shown in the diagram extends in the same direction. Those who are accustomed to this technology can also understand that in other embodiments of the present creation, based on factors such as maximum area utilization, sheet stress, ease of stamping, etc., there is no limitation to this type. For example, part of the alloy resistor wiring circuits and the dual-digit alloy resistor wiring circuits extend in different directions, or the spaced alloy resistor wiring circuits (for example, divided into dual-digit and single-digit alloy resistor wiring circuits) extend in different directions. Furthermore, alternatively, the two ends of each alloy resistance wiring circuit can also be respectively connected to the first punched side edge 22 and the second punched side edge 23 of the alloy sheet 1 instead of being disconnected at one end.

Referring to FIG. 8, it shows that in each of the alloy resistance layout loops 31, 32, 33, the planned layout includes a plurality of series arrays of alloy resistance regions that are spaced and adjacent to each other. For example, taking the alloy resistance layout circuit 31 as an example, a series array 4 of alloy resistance regions is planned to be deployed in the alloy resistance layout circuit 31, and the series array 4 of alloy resistance regions further includes a plurality of spaced adjacent ones. Alloy resistance zone 41, 42, 43, 44, 45. Each alloy resistance zone is defined with an injection-molded section and conductive sections located at opposite ends of the injection-molded section.

Referring to FIG. 9, in the subsequent manufacturing process, each of the alloy resistance regions 41, 42, 43, 44, and 45 is then packaged by the package body 51, 52, 53, 54, 55. After the package bodies 51, 52, 53, 54, 55 are hardened, they can protect the alloy resistance and achieve the purpose of insulation. The material selected for the package body 4 can be epoxy resin or other materials with good insulation and coating effects.

Finally, each alloy resistance zone can be separated, and a plurality of alloy resistance monomers can be completed. The two ends of the alloy resistor monomer are then made of conductive terminal materials to form conductive terminals to facilitate the welding operation in practical applications in the future.

The above-mentioned examples are only used to illustrate the creation, not to limit the scope of the creation. All other equivalent modifications or replacements completed without departing from the spirit of the creation should be included in the scope of the patent application described below. Inside.
