Description
Technical field
It the utility model is related to micro-wave oven technical field, more particularly to a kind of micro-wave oven frequency changing power device.
Background technology
Common micro-wave oven variable-frequency electric source plate uses single side pcb board, and plate upward wiring resource is less, generally requires using additional
The method increase cabling resource of conducting wire；In addition fixed volume and the larger device of weight are needed on plate, in order to increase intensity, these
The pad via of device needs to stamp rivet, then carries out device welding again, adds material, equipment, the input in man-hour.For
The device of medium wt, uses the method that dispensing is fixed to add material and processing cost to improve fixing intensity.
The content of the invention
In view of this, the technical problem to be solved by the present invention is to provide a kind of micro-wave oven frequency changing power device, with solution
Certainly existing micro-wave oven variable-frequency power sources structure on the whole processed complex the problem of.
Technical solution is as follows used by the utility model solves above-mentioned technical problem：
A kind of micro-wave oven frequency changing power device, comprising double-sided PCB board, sets frequency changer circuit on the double-sided PCB board, described
It is fixed with SMT devices, and the double-sided PCB board by Reflow Soldering mode to set on double-sided PCB board and some is connected by via
The two-sided pad connect, the two-sided pad interpolation enters transformer, resistance, capacitance, inductance, high-voltage diode, and passes through wave-soldering
Mode is welded and fixed.
Further, the capacitance includes CBB electric capacity.
Further, the resistance includes cement resistor.
The micro-wave oven frequency changing power device that the utility model is realized, the micro-wave oven variable-frequency power sources dress that the utility model is realized
Put, micro-wave oven variable-frequency power sources is made using two-sided PCB, adds wiring space, integrated level higher, the two-sided pad of two-sided PCB
The component of fixed larger volume and weight, there is the structure and effect of similar rivet, eliminates the techniques such as riveter nail, point fixing glue
Step, reduces the cost of whole microwave oven supply power, improves reliability.
Brief description of the drawings
Fig. 1 is micro-wave oven frequency changing power device part-structure schematic diagram provided by the utility model.
In figure：
1st, double-sided PCB board
2nd, two-sided pad
3rd, SMT devices
Embodiment
In order to make technical problem to be solved in the utility model, technical solution and beneficial effect clearer, clear, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is further elaborated.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
The utility model provides a kind of micro-wave oven frequency changing power device, as shown in Figure 1, comprising double-sided PCB board 1, it is described double
Frequency changer circuit is set on face pcb board 1, SMT devices 3, the present embodiment are fixed with by Reflow Soldering mode on the double-sided PCB board 1
In, for the space of reasonable arrangement pcb board, SMT devices are arranged at regional extent of the top by proximal edge of the double-sided PCB board
It is interior.And some two-sided pads 2 are set on the double-sided PCB board 1, the two-sided pad 2 is arranged at the double-sided PCB board 1
Two sides correspondence position, and in the center via of pad.Via is also referred to as plated through-hole, in dual platen, to connect each layer
Between printed conductor, bore a common aperture, i.e. via in the intersection of conducting wire that each layer needs to connect.In technique, mistake
Last layer metal is plated with the method for chemical deposition on the hole wall cylindrical surface in hole, to connect the copper foil that middle each layer needs to connect,
And the upper and lower surface of via makes circular pad shape.The size and shape of the two-sided pad is unlimited, including but not limited to figure
Shown in circle, ellipse.The two-sided pad interpolation enters transformer, resistance, capacitance, inductance, high-voltage diode, and passes through
Wave-soldering mode is welded and fixed.The capacitance includes CBB electric capacity, i.e. polypropylene capactive, and the resistance includes cement resistor.
The micro-wave oven frequency changing power device that the utility model is realized, micro-wave oven variable-frequency power sources, increase are made using two-sided PCB
Wiring space, integrated level higher, the two-sided pad of two-sided PCB fix larger volume and the component of weight, there is a similar rivet
Structure and effect, eliminate riveter nail, the point processing step such as fixing glue, reduce the cost of whole microwave oven supply power, improve
Reliability.
Above by reference to the right of the preferred embodiment for having illustrated the utility model, not thereby limitation the utility model
Scope.Those skilled in the art do not depart from any modification made in the scope of the utility model and essence, equivalent substitution and change
Into should all be within the interest field of the utility model.
