Specific embodiment

Fig. 1 shows the schematic diagram of the electronic module 100 according to one embodiment.Electronic module 100 includes having first device The circuit board component 102 of part side 104 and contact side 106.Two sides 104,106 be circuit board component 102 it is mutual back to side. Illustratively, component side 104 is herein the upside of circuit board component 102, and contacting side 106 is circuit board component 102 Downside.Circuit board component 102 is equipped with the electronic component 108 for generating heat on component side 104.Actually circuit board member Part 102 can also for example have multiple components 108 on component side 104.Circuit board element 102 is via heat conducting film 110 With 112 thermal bonding of transmission components as cooling fin, the e.g. hydraulic plate made of (aluminium) pressed article.110 cloth of heat conducting film Set contact side 106 with component 108 back to surface section and transmission components 112 with contact side 106 back to table Between facial section.By allowing circuit board component 102 and transmission components 112 to clamp, heat conducting film 110 not only presses to face formula contact Press to transmission components 112 to side 106 and face formula.Corresponding hot path is with from component 108 towards transmission components 112 The vertical arrows that direction is directed toward indicate.

It is this to clamp according to Fig. 1 illustratively by the first clamping element 114 in the first screw form and in the second spiral shell Second clamping element 116 of silk form is realized.Herein, the first clamping element 114 is guided through in circuit board component 102 First through hole 118 and the second clamping element 116 are guided through the second through-hole 120 in circuit board component 102.Speed changer portion That part 112 is respectively provided on the position opposed with through-hole 118,120 is suitable, by the face 122 that is spirally connected of working process, herein By it is slightly elevated be spirally connected pedestal in the form of.In addition, transmission components 112 have suitably, by the contact surface of working process 124, herein in the form of slightly elevated contact pedestal, heat conducting film 110 is fitted in this to face formula in the state of being extruded On a contact surface.Between the face of being spirally connected 122 and contact surface 124, circuit board 102 is not sticked in transmission components 112.As a result, Ensure that circuit board component 102 is only contacted with the section of the restriction of transmission components 112.

For example, heat conducting film 110 is applied on circuit board component 102 with depending on the millet cake formula of component 108.Here, leading The face of hotting mask 110 especially selects the almost size as the face of component 108.As alternative, heat conducting film 110 also extends super The section of oversampling circuit panel element 102 being located at outside component 108.

According to one embodiment, component 108 is surrounded by shell 126.Illustratively, according to shell 126 shown in FIG. 1 Extend beyond the entire surface of component side 104.Shell 126 is for example embodied as thermoset package body.The shell 126 has for holding Receive the first clamping element 114 first shell through-hole 128 and second shell through-hole 130 for accommodating the second clamping element 116. Here, first shell through-hole 128 is opposed with first through hole 118, and 130 second through-hole 120 of second shell through-hole is opposed.As Alternative, shell 126 only extend in one or more local section of component 104, such as each in order to dividually encapsulate Component.

According to one embodiment, shell 126 is constituted by being used to the Embedding Material of encapsulating component side 104.

Fig. 2 overlooks the schematic diagram for showing the electronic module 100 in Fig. 1.Show two clamping elements 114, 116 special arrangement mode.The two clamping elements 114,116 are located in as follows on circuit board component 102, that is, so that member Device 108 is located at will be on two clamping elements 114,116 straight lines 200 interconnected.Therefore component 108 is located at two clampings Between element 114,116.Particularly advantageously, straight line 200 extends beyond component 108 in the form of cornerwise, as in Fig. 2 In be exemplarily illustrated as.Here, the length of the section for passing across component 108 of especially straight line 200 is greater than first device The maximum width B of part 108.Threaded connection in this way can realize safe and reliable clamping.

It is stated alternatively the different embodiments of bright viewpoint proposed by the present invention again below.

According to one embodiment, the unilateral assembly of circuit board component 102.The component 108 of heat is generated for example via soldering heat It is bonded on circuit board component 102.

According to another embodiment, circuit board component 102 on component side 104 or also on contact side 106 with plastics, Such as thermosetting plastic or other suitable case material encapsulatings, so that protecting the soft copy of electronic module 100 for example has protection With grease proofing or other liquid.

Circuit board 102 is especially directly thermally bonded to being spirally connected on face 122 of transmission components 112.Heat conducting film 110 is in this example Such as it is located in oily region.

According to another embodiment, circuit board 102 is implemented as FR4 circuit board.

Heat conducting film 110 is for example embodied as so-called gap fillers.Itself more particularly to filling material solid or paste Material minimizes the thermal resistance between component 108 and transmission components 112 by packing material.Gap fillers can be well It compresses and there is elasticity.It is possible thereby to enduringly avoid because tolerance, structure height difference or the different coefficients of expansion draw Air gaps rise, between circuit board component 102 and transmission components 112.By the elasticity of the restriction of gap fillers, realize Corresponding pressure is applied on heat conducting film and circuit board component and heat conducting film and transmission components respective adjacent surfaces.Thus It can be realized particularly efficient thermal bonding in the case where extruding force very little.In addition, gap fillers are self-adhesions, by This realizes the simple pre-installation of heat conducting film 110.In addition, the gap fillers can be removed residue-free.It is achieved in electricity The disassembled simply of submodule.

As alternative, heat-conducting cream by being applied on contact side 106 or realizing in transmission components 112 by heat conducting film 110.

As described, it is advantageous to heat conducting film 110 only point type generate heat component 108 area It is applied in domain on circuit board component 102.The face of heat conducting film 110 matches the generation heat of component 108 or the face that row is thermally conductive herein.

Component 108 is arranged as follows in terms of designing technique, that is, by the way that electronic module 100 is threaded in speed change Ensure that heat conducting film 110 is clamped on relevant position on device component 112.For this purpose, transmission components 112 for example with as follows at The face 122 that is spirally connected of shape, that is, circuit board component 102 not only sticks on screwing position but also sticks on heat conducting film 110 In region.

Electronic module 100 is, for example, the control circuit for transmission control.For this purpose, electronic module 100 especially can be with It is directly integrated into the speed changer for needing to control.

By the above-mentioned encapsulation and cooling concept of electronic module 100, it can save and arrange the additional insert led for heat, Such as aluminium inserts.

Fig. 3 is shown for arranging electronic module according to the embodiment, such as electronic die that describes above by Fig. 1 and 2 The flow chart of the method 300 of block.Here, preparing circuit board component in first step 310.Realizing in second step 320 will Heat conducting film be arranged in contact side and component back to surface section and transmission components surface section between.In third step In rapid 330, circuit board component and transmission components are clamped, so that heat conducting film presses to the surface section and transmission components of contact side Surface section.
