Definitions
- the invention offers a tool especially suitable for carrying out this joint operation between layers of a circuit using induction welding technology.
- the invention also relates to a method in which this tool is involved and to a machine incorporating the tool.
- the technique of joining layers of a multilayer printed circuit by induction is known from patent document EP 1460890.
- the joining process comprises the step of generating a magnetic field that passes through the package precisely through said turns or specks, inducing electric currents in them that by joule effect generate enough heat to melt adjacent layers of resin layers, which polymerize solidify and cause the irreversible union between the layers with circuit image.
- multilayer printed circuits are increasingly complex while increasing the demand for quality and compactness and this creates new needs that did not exist to date.
- Such is the case of multilayer printed circuits of high density interconnection of its internal layers, and especially those that combine zones of rigid circuit with flexible ones, that require the use of sheets of the order of thicknesses and materials that do not have a predictable mechanical expansion or contraction behavior. This causes that once formed the package, during the manipulation of these in subsequent manufacturing operations misalignments occur between rigid internal layers and flexible layers, which causes a high level of rejection or defective material.
- an upper magnetic conductor is arranged on the upper face of the formed package, in coincidence with a spiral or metallic speck of the upper sheet, and a lower magnetic conductor applied against the lower face of the package in coincidence with the corresponding spiral or metallic speck of the lower leaf, and a magnetic field is generated confined by said conductors that crosses the package.
- said package must be seated or supported by a tool that avoids lateral displacements of both the package and its inner layers. At the same time, it should be avoided that this tool disturbs the magnetic field that passes through the package or that it is heated by the effect of it and is an unwanted source of heat.
- the known tools formed by a single or several assembled parts, have a plate shape that does not completely cover the bottom face of the package but that said plate is provided on its periphery with recesses or openings through which The lower magnetic conductor has access to the lower face of the sheet that constitutes the lower layer of the package.
- These entrances or openings that discover the package below coincide with the reserve area of which The sheets with circuit image of the package are provided, generally of standard dimensions so that the same tool can be used for the manufacture of different packages or multilayer printed circuits.
- it is considered to make unions between layers by internal points of the sheets that constitute them, they must be made useful for each circuit because the turns or metal spots are located in the sheets according to the particular circuit images for each printed circuit to be manufactured.
- the designer first designs the circuit and then selects, depending on the available space between the circuit images on the sheets, the location of the turns or metal specks. If conventional tools are used, they must be provided with openings precisely in those areas where the turns or metal specks will be located to allow the lower magnetic conductor to be applied against the bottom face of the sheet that constitutes the bottom layer of the package in coincidence with the mentioned turns or metal specks.
- the tool must also guarantee extreme reliability, in the sense that it must offer a support surface for the absolutely flat package, so that the package does not warp and its layers are completely flat during the joining operation.
- the same tool must also be suitable not to disturb the magnetic field confined by the magnetic conductors, and not to be heated by its effect.
- Patent document WO 2008028005 describes a machine capable of making joints between the layers of a package of a printed circuit multilayer supposedly advantageous with respect to the technology described in EP 1460890. While in this document EP 1460890 describes the use of pairs of welding electrodes mounted facing on respective arms of a C-shaped magnetic core and capable of moving away or approaching each other to apply each on opposite sides of the package and confine a magnetic field that crosses the package from one electrode to another, WO 2008028005 describes the use of an E-shaped magnetic core intended to be applied on a face of the package to confine a magnetic field whose field lines cross the package through three zones from each of the extreme branches of the E to the central branch when these are applied on a face of the package.
- WO 2008028005 while the junction bridge between the arms of the C avoids by stop against the edge of the package that the electrodes can be arranged on interior areas of the package, the solution in E allows the magnetic core to be freely arranged on any area of the package, consequently allowing mechanical connections between the layers of the package to be made without any internal limitations.
- WO 2008028005 does not indicate or suggest however what the purpose may be or what are the circumstances that may be of interest to make these joints in interior areas.
