Definitions
- the present invention a multi-pressing process for the manufacture of printed circuits and printed circuit thus obtained, consists of a system of production of printed circuits of those used in the electronics industry, which comprises the bending of a printed circuit of determined thickness, being able to increase its versatility, especially in applications where high space utilization is required. That is why the present invention will be of special interest for the electronics industry in general and especially for manufacturers of printed circuits of special characteristics.
- the copper conductive part must have a thickness of at least 400 microns to avoid its breakage when bent.
- the present process of multifresado for the manufacture of printed circuits whose conductive plate has a thickness less than 400 microns it is possible to give a treatment to the base plate of the circuits that allows to make one or multiple folds (up to 180 °), of progressive nature, so that the metal tracks are not damaged or any breakage of the conductive plate occurs after milling of the support substrate.
- the present multi-pressing process consists of a system for adapting the substrate of printed circuit boards, for the production of fold zones where to fold said printed circuits.
- This procedure consists of a system of multifresado, by means of a strawberry of special characteristics, composed of a roller provided on its surface with a multitude of polishing bands, capable of making a recess in several parallel bands in the aforementioned fold zone of a printed circuit , allowing its subsequent folding without deteriorating the conductive tracks of metallic material, adhered to the substrate of the printed circuit, on the opposite side to the milled surface.
- the present procedure allows to bend not only printed power circuits with high conductive layer thicknesses (400 microns) but also printed signal circuits whose thicknesses are smaller due to the lower intensity circulating through them. In this way it is possible to fold printed signal circuits without using more conductive material than is necessary, which implies the consequent saving of material.
- the printed circuit obtained following the procedure described above consists of a folded circuit with at least one conductive part adhered to the insulating or supporting substrate.
- Figure 1 shows a perspective view of the bending system by means of a single milling for printed circuit boards with copper conductive layer with a thickness of 400 microns.
- Figure 2 shows a perspective view of a printed circuit produced by the present multi-pressing process for printed circuit boards with copper conductive layer and thickness of 105 microns.
- Figure 3 shows a perspective view of the previous printed circuit during the multi-pressing phase.
- the multi-pressing process for the manufacture of printed circuits illustrated in this preferred embodiment is constituted essentially by a method of adapting the substrate of the printed circuit boards 1, for the production of fold zones 2 where the layer is folded of copper of said printed circuits 1.
- the conductive layer has a thickness of 105 microns, although this can vary between 65 and 400 microns.
- This procedure consists of a multi-pressing system, by means of a milling cutter 3 of special characteristics, composed of a roller provided on its surface with a multitude of polishing bands or teeth, capable of making a recess in the form of parallel bands 4 in said area of fold 2 of a printed circuit 1, allowing its subsequent folding without deteriorating the copper conductive tracks, adhered to the substrate of the printed circuit, on the opposite side to the milled surface.
- a milling cutter 3 of special characteristics, composed of a roller provided on its surface with a multitude of polishing bands or teeth, capable of making a recess in the form of parallel bands 4 in said area of fold 2 of a printed circuit 1, allowing its subsequent folding without deteriorating the copper conductive tracks, adhered to the substrate of the printed circuit, on the opposite side to the milled surface.
- the milling cutter 3 acts on the support substrate of the copper conductive layer 1 eliminating material in multiple parallel bands 4 until reaching the final thickness of the substrate that allows the folding of the conductive copper layer of 105 microns until reaching 180 °, preventing its break.
