Definitions
- the invention relates to a drive system with converter.
- Inverter can be fed, so that the speed of the electric motor is adjustable. At high electrical power and thus high currents busbars are used to conduct electricity.
- the invention is therefore the object of developing a drive system, with a simple production in a cost effective manner and stable and compact way to do.
- more than three layers carry a first potential and three others a different potential. If the layers with different potential alternate, especially in the normal direction to the PCB level, is a particularly low
- the layer thickness of the conductor tracks are each between 70 ⁇ and 200 ⁇ .
- the advantage here is that a high current is istleitbar.
- high voltages, such as 1000 volts are allowed between the next adjacent layers.
- a component in particular a capacitor, is arranged on the printed circuit board, wherein the connecting wires of the component are each arranged in a first through-connection.
- the printed circuit board on further vias each having the same distance to a first via, in particular wherein the clear diameter of the first via is larger than the clear diameter of the respective further via, in particular wherein the further vias are aligned parallel to the first via.
- the further plated-through holes are in
- the multilayer printed circuit board has between five and twenty-one layers.
- the advantage here is that many layers thus lead to a first or second potential. Further advantages emerge from the subclaims.
- the invention is not on the
- FIG. 1 shows a plan view of a multilayer printed circuit board of an arrangement according to the invention, wherein a first through-connection 5 for improving the solder connection to be effected on it is provided by further, in particular parallel aligned
- Vias 6 is surrounded.
- FIG. 2 shows an associated sectional view along a web 2.
- the arrangement has the multilayer printed circuit board, that is to say multilayer printed circuit board, in order to function as a low-inductive DC link connection.
- the arrangement is providable in an inverter, which is a mains-powered
- the multilayer printed circuit board is provided.
- This multilayer printed circuit board has a plurality of parallel layers whose interconnects are made of copper-containing material and have a layer thickness between 70 ⁇ and 350 ⁇ .
- Insulating material is arranged between the layers aligned parallel to one another, wherein between adjacent layers, in particular directly adjacent layers,
- the insulating material has a corresponding insulation resistance.
- the next adjacent layers of the circuit board each have different potential.
- the first layer has an upper DC link potential when the
- the layers are 300 ⁇ spaced apart. In other embodiments, a distance between 150 ⁇ and 400 ⁇ advantageous. As shown in FIG. 2, the printed circuit board has six layers. In other words,
- the number of layers is between six and fourteen layers.
- the total thickness of the circuit board is exemplified 3mm, in particular between about 1, 5mm and 5mm.
- To smooth the DC link voltage at least one capacitor is fitted on the circuit board.
- the connecting wires of the capacitor are inserted into a first through-connection 5.
- the plated-through hole 5 is designed as a cylindrical recess, which is aligned perpendicular to the printed circuit board plane.
- the wall of the via 5 is coated with copper.
- the tracks of several layers of the multilayer printed circuit board touch this metallized wall.
- the interconnects disposed between these layers are spaced from the metallized wall.
- These further plated-through holes 6 are preferably evenly spaced from one another and each have the same distance to the first through-connection 5.
- the hole pattern of the further vias 6 appears circular.
- the centers of the further vias 6 are arranged on a circle.
- the via 6 each penetrate a circular ring with a ring width in the radial direction, which is greater in magnitude than the respective diameter of the further vias 6.
- the distance between the further vias 6 of the first via 5 is so small that when immersed in a solder bath the in the other and the first
- Webs in the circumferential direction are less than a fifth of the ring width of the annulus extended.
- the respective web is so thin that the soldering bath passing through a contacting amount of solder, which on the annulus and arranged there vias (5, 6) touching gives heat to the metallic areas of the circuit board sufficient to sufficient high temperature to produce a sufficiently good solder joint.
- the webs for heat dissipation prevent.
- the heat transferred from the solder bath to the annulus and the vias (5, 6) located there is sufficient to achieve a sufficiently high temperature.
- the further plated-through holes 6 cause the solder to rise in them and thus the first through-hole 5 of the radially surrounding them
- Vias is heated or at least prevents heat dissipation away from the first via 5 or at least weakened. Therefore, a sufficiently high temperature can be achieved in the first via 5 during soldering for a sufficiently long period of time, even if the connecting wire of the capacitor inserted in the first via 5 dissipates heat.
- the clear diameter of the first through-connection 5 is greater than the respective clear diameter of the further plated-through holes 6.
