Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In the household electrical appliance field, the product after the design can be produced in large batch, and in the process of the large batch production, the production cost and the efficiency greatly influence the profits of enterprises, so how to reduce the production cost of each part of the household electrical appliance product, and the improvement of the production efficiency is an important research direction of each household electrical appliance production enterprise.
The design of household appliances is more and more humanized, and the functions are more and more, wherein partial functions need to be supplied with power uninterruptedly. For example, the time switch function and the clock display function of various home appliances require uninterrupted power supply to the clock provided in the home appliance; for example, a user-defined washing program in a washing machine, a user-defined setting of a television set, and the like also need to perform uninterrupted power supply on a memory in a household appliance, so that the storage states of various configurations can be maintained after an external power supply is cut off. Therefore, batteries are installed in a plurality of household appliances, and the batteries are used as part of components needing uninterrupted power supply to supply power, so that the influence on the normal use of users after the external power supply of the household appliances is cut off is avoided.
In order to improve the production efficiency and reduce the production cost of the household electrical appliances, the circuit boards of the household electrical appliances are generally welded by adopting an automatic welding method such as wave soldering or reflow soldering and the like during mass production. Wave soldering is to make the soldering surface of the circuit board directly contact with high-temperature liquid tin to achieve the purpose of soldering. Reflow soldering is to heat air or nitrogen to a high enough temperature and blow it to the circuit board with the components attached, so that the solder on both sides of the components melts and bonds with the circuit board. Wave soldering is mainly used for soldering plug elements, and reflow soldering is mainly used for soldering surface-mounted elements. Wave soldering or reflow soldering has high soldering efficiency, can realize pipelined automatic soldering, has better soldering effect than manual soldering, and saves cost compared with manual soldering, thus being generally applied to large-batch circuit board soldering. However, in order to ensure the soldering quality, the ICT test is required to be performed on the circuit board after the circuit board is subjected to wave soldering or reflow soldering.
The ICT test is a standard test means for detecting defects in production and manufacture and defects of components by testing electrical performance and electrical connection of online components. The method mainly checks the on-line single component and the open circuit and short circuit conditions of each circuit network, has the characteristics of simple operation, rapidness, accuracy in fault location and the like, and is a component-level test method. Specifically, a special needle bed is designed according to the wiring of a circuit board, a probe on the needle bed is contacted with a component on the welded circuit board, and a discrete isolation test is carried out by using hundreds of millivolts and current within 10 milliamperes, so that the faults of missing installation, wrong installation, parameter value deviation, welding point continuous welding, circuit board open and short circuit and the like of universal and special components such as installed resistors, inductors, capacitors, diodes, triodes, silicon controlled rectifiers, field effect tubes, integrated blocks and the like are accurately measured.
The testing principle of ICT determines that components on a circuit board cannot be electrified during testing, and if current passes through the components during ICT testing, interference is certainly caused to ICT testing results. Therefore, when performing the ICT test, it is necessary to disconnect the battery on the circuit board, that is, the battery cannot be connected on the circuit board until the circuit board passes the ICT test.
The battery on the circuit board has two connection modes, one is to weld the battery on the circuit board directly, and the other is to weld a battery seat on the circuit board firstly and then install the battery in the battery seat. The mode of welding the battery seat on the circuit board firstly increases the component of the battery seat, increases the cost of the circuit board, and in addition, the battery can be installed in the battery seat only in a manual mode, so that the production efficiency of the circuit board is also reduced. In the mode of welding the battery on the circuit board, the battery needs to be welded after the circuit board passes the ICT test, so the battery can be welded only in a manual mode, and the production efficiency is also low.
For the above reasons, embodiments of the present invention provide a circuit board with a battery and a manufacturing method thereof, which are used to solve the above problems.
Fig. 1 is a schematic structural diagram of a circuit board with a battery according to an embodiment of the present invention, and as shown in fig. 1, the circuit board with a battery according to the embodiment includes: circuit board 11, battery 12, other components 13.
The Circuit Board 11 may be any Circuit Board that can be soldered by wave soldering or reflow soldering, such as a single-layer, double-layer or multi-layer Printed Circuit Board (PCB), a Flexible Printed Circuit (FPC), and the like. A battery 12 and a plurality of other components 13 are soldered to the circuit board 11. Only one other element 13 is shown in fig. 1, but it is understood that the number of other elements 13 on the circuit board 11 is not limited to fig. 1, the kinds and the number of other elements 13 are determined according to the function of the circuit board 11, and the circuit formed by each other element 13 completes the function of the circuit board 11. The further elements 13 may be, for example, resistors, capacitors, inductors, diodes, transistors, field effect transistors, integrated circuits, etc. At least one of the other elements 13 needs to be powered by the battery 12, such as the other elements 13 shown in fig. 1.
The circuit board 11 is provided with a battery positive pin 14 and a battery negative pin 15, the positive electrode of the battery 12 is welded on the battery positive pin 14, the negative electrode of the battery 12 is welded on the battery negative pin 15, and the battery 12 is taken as a button battery in fig. 1 as an example. The circuit board 11 is further provided with a device pad 16 and a device pad 17, and the other component 13 is soldered between the device pad 16 and the device pad 17, where the other component 13 is a two-port component. A first short contact 18 and a second short contact 19 are also provided on the circuit board 11, the first short contact 18 being connected to the battery positive pin 14, and the second short contact 19 being connected to the device pad 17. The first shorting contact 18 is open to the second shorting contact 19.
In the circuit board with battery shown in fig. 1, the battery 12 is soldered on the circuit board 11, and the battery positive terminal pin 14 is connected to the first shorting contact 18, and the first shorting contact 18 and the second shorting contact 19 are opened, so that the battery 12 and other components 13 form a circuit, that is, the other components 13 are not powered. Therefore, the battery 12 and other components 13 can be welded on the circuit board 11 together in wave soldering, reflow soldering and other automatic welding modes, the circuit board 11 can also normally perform ICT test after the welding is finished, the battery 11 does not form a loop, current cannot be generated on the circuit board 11, and the ICT test cannot be influenced. After the circuit board passes the ICT test, the first shorting contact 18 and the second shorting contact 19 can be shorted. Here, the first shorting point 18 and the second shorting point 19 may be short-circuited by manual welding.
Because when carrying out wave-soldering, reflow soldering etc. automatic weld to circuit board 11, can be stained with the welding material on first short contact 18 and the second short contact 19, when carrying out short-circuit connection with first short contact 18 and second short contact 19 then, need not to add extra welding material again, only use welding tool spot welding such as flatiron to accomplish short-circuit connection once, and is very convenient, and not high to welding workman's technical requirement, can not produce the influence because workman's welding level is not high to circuit board 11 welding quality, to skilled welding workman, only need several seconds can accomplish weldment work, can not produce too much influence to circuit board 11's production efficiency. In the traditional circuit board with the battery, the whole battery needs to be welded manually after the circuit board is welded automatically, the whole battery is welded, the welding technology is required by the welding, and if the welding point quality is not high, the power supply performance of the battery is possibly influenced; in addition, even a skilled welder requires several tens of seconds, which affects the production efficiency of the circuit board. Therefore, the production efficiency of the circuit board with the battery provided by the embodiment of the invention is higher than that of the traditional circuit board with the battery, a skilled welder is not needed for carrying out subsequent welding work, and the production cost is also saved.
The first short contact 18 shown in fig. 1 is connected to the battery positive electrode pin 14, but the first short contact 18 may be connected to the battery negative electrode pin 15 as well, as long as the connection between the battery 12 and the other element 13 is cut off.
According to the circuit board with the battery provided by the embodiment of the invention, any pin of the battery on the circuit board is connected with the first short-circuit point, and the second short-circuit point which is open-circuited with the first short-circuit point and can be in short-circuit connection with the short-circuit point is arranged, so that the battery on the circuit board with the battery can be welded with other elements on the circuit board through automatic welding, the production efficiency of the circuit board with the battery is improved, and the production cost is reduced.
In the embodiment shown in fig. 1, the first short contact 18 and the second short contact 19 are open and can be connected to each other by short circuit. However, in order to facilitate the short-circuiting of the first shorting contact 18 and the second shorting contact 19 and to improve the efficiency of the short-circuiting, the distance between the first shorting contact 18 and the second shorting contact 19 needs to be as small as possible. The distance between the first short contact 18 and the second short contact 19 may be determined according to the maximum distance that can connect two short contacts in one spot welding, which is different according to the welding level of the welding tool and the welding worker, and is called a preset threshold, and the distance between the first short contact 18 and the second short contact 19 is smaller than the preset threshold. Typically, the predetermined threshold may be 1 mm.
In addition, since the circuit board 11 needs to be soldered by automatic soldering methods such as wave soldering or reflow soldering, which all have a minimum distance requirement between the solder pads, if the distance between the solder pads is smaller than the minimum distance requirement, two open solder pads may be soldered together during the automatic soldering process. Therefore, the distance between the first shorting point 18 and the second shorting point 19 must not be too close, at least greater than the minimum distance required for the automated soldering method used for the circuit board 11. Typically, the minimum distance is required to be 0.1 mm or 0.2 mm. That is, the distance between the first shorting point 18 and the second shorting point 19 is less than 1 mm and greater than 0.1 mm, or less than 1 mm and greater than 0.2 mm. The minimum distance requirement is determined by the performance of the automated soldering process used for the circuit board.
In the embodiment shown in fig. 1, the battery 12 is a button cell battery, which is often called button cell battery, but the battery 12 may also be any battery such as a zinc-manganese battery (i.e. dry cell battery), rechargeable battery, etc. suitable for supplying power to the components on the circuit board.
The circuit board with the battery shown in fig. 1 may be disposed in a household appliance that needs the battery to supply power to devices on the circuit board, but in the production process of the circuit board, the circuit board without components and parts welded needs to be designed and manufactured first, and then each device can be welded on the circuit board through a welding process, so as to obtain the circuit board with the devices welded. Then certain modifications may be made to the circuit board without soldered components in order to produce the circuit board with battery shown in the embodiment of fig. 1, as shown in fig. 2.

For example, the battery positive electrode pad 24 and the battery negative electrode pad 25 may be insertion type pads or mounting type pads.
The battery positive electrode pad 24 is connected to the first shorting point 26, the first shorting point 26 is opened to the second shorting point 27, and the first and second shorting points 26 and 27 can make a shorting connection. In fig. 2, the battery positive electrode pad 24 is connected to the first short contact 26, but the battery negative electrode pad 25 may be connected to the first short contact 26.
The other component bonding site 23 comprises a plurality of pads, two pads being exemplified in fig. 2, namely a first pad 28 and a second pad 29, the second short 27 being connected to the first pad 28. The pads of the other component soldering position 23 connected to the second shorting contact 27 indicate that the component to be soldered at the other component soldering position 23 needs to be powered by the battery, and the number of pads connected to the second shorting contact 27 is determined according to the requirements of the component.
The circuit board 21 may be any circuit board that can be soldered by wave soldering or reflow soldering, such as a single-layer, double-layer or multi-layer PCB, FPC, or the like.
In the circuit board shown in this embodiment, because the first short contact and the second short contact which are open-circuited are connected to one pad at the battery mounting position, components including the battery on the circuit board can be automatically soldered by soldering methods such as wave soldering and reflow soldering, so that the soldering efficiency of the circuit board is improved.

Fig. 3 is a flowchart of a method for manufacturing a circuit board with a battery according to an embodiment of the present invention, and as shown in fig. 3, the method according to the embodiment includes:
s301, placing each component on a circuit board, and automatically welding the circuit board with the components; the circuit board comprises a battery, a first short contact and a second short contact, wherein the first short contact and the second short contact are mutually open-circuited, and the first short contact is connected with any pin welding pad of the battery.
Specifically, the method provided by the embodiment is to weld the circuit board with the battery, and in order to improve the efficiency of welding the circuit board with the battery, automatic welding is required to be performed on the circuit board with the battery. In the process of automatically soldering a circuit board, it is necessary to first place each component to be soldered on the circuit board at a position corresponding to each component. For the plug-in element, pins of the plug-in element are plugged in corresponding welding holes on the circuit board; in the case of mounting a component, the mounted component is placed on a corresponding position on the circuit board, and the mounted component may need to be bonded to the circuit board in order to avoid misalignment of the mounted component. The circuit board comprises a battery, a first short contact and a second short contact, wherein the first short contact and the second short contact are mutually open-circuited, and the first short contact is connected with any pin welding pad of the battery.

And step S303, short-circuiting the first short-circuit point and the second short-circuit point on the circuit board passing the ICT test.
Specifically, after the circuit board passes the ICT test, the first short-circuit point and the second short-circuit point can be connected in a short-circuit mode, so that the battery is connected into the circuit, and the final welding of the circuit board is completed.
Generally, a soldering iron may be used to short the first shorting point and the second shorting point on a circuit board that passes ICT testing. Because when carrying out automatic weld to the circuit board, can glue the welding material on first short-circuit point and the second short-circuit point, when carrying out short-circuit connection with first short-circuit point and second short-circuit point, need not to add extra welding material again, only use welding tool such as flatiron once spot welding to accomplish short-circuit connection, it is very convenient, and not high to welding workman's technical requirement, can not produce the influence because workman's welding level is not high to the welding quality of circuit board, to skilled welding workman, only need several seconds can accomplish weldment work, can not produce too much influence to the production efficiency of circuit board. In the traditional circuit board with the battery, the whole battery needs to be welded manually after the circuit board is welded automatically, the whole battery is welded according to requirements on welding technology, and if the welding point quality is not high, the power supply performance of the battery is possibly influenced; in addition, even a skilled soldering worker requires several tens of seconds, which affects the production efficiency of the circuit board. Therefore, the manufacturing method of the circuit board with the battery provided by the embodiment of the invention has higher production efficiency than the traditional manufacturing method, does not need skilled welders to perform subsequent welding work, and also saves the production cost.
