Description

Leitungszüge in gedruckten Schaltungen ---------------------- Neuerung Die bezieht sich auf eine gedruckte Schaltung. Die elektrischen Widerstände von Leitungszügen in gedruckten Schal- tungen lassen sich nur grob vorausberechnen, da die Dicken und Breiten der Leitungszüge herstellungsbedingt schwanken.Cable runs in printed circuits ---------------------- innovation The refers to a printed circuit. the electrical resistance of cable runs in printed circuit can only be roughly calculated in advance, since the thicknesses and The widths of the cable runs vary due to the manufacturing process.

Legt man auf die genaue Einhaltung gewisser Widerstandswerte werts ist es erforderlich, die Leitungszüge nach ihrer Herstellung teilweise abzuschleifen oder abzukratzen. Hierbei wird jedoch häufig die Trägerunterlage für die gedriclte Scja;timg be= schädigt., Außerdem lösen sich hierbei leicht die Leitungszüge von der Unterlage ab. neuerungs Es werden daher xfiN-Bgemäß in der gedruckten Schaltung Leitun, & Leitungszüge vorgesehen, die in mehrere, untereinander verbind- bare Leitungsteile unterteilt sind und zwar derart, daß durch Hinzuschalten oder Abschalten von Leitungsteilen in den Leitungszug der elektrische Widerstand des Leitungszugs wahlweise zu verändern ist. Neuerung In Ausbildung der m ; Sa=E sind die einzelnen Leitungsteile zu- einander räumlich parallel angeordnet und weisen verbreiterte Enden'auf 0 Die Leitungsteile können dann in einfacher Weise durch Lottropfen wahlweise elektrisch hintereinander oder parallel ge- schaltet werden. Neuerung In einer einf achen Abånierung der 3g sind herstellungsge- mäß die einzelnen Leitungsteile zunächst miteinander verbunden und es kann der elektrische Widerstand des Leitungszug durch Auftrennen der einzelnen Leitungsteile verändert werden. Neuerung Weitere Einzelheiten der ; S er, geben sich aus der nachfol- genden Beschreibung von drei Ausführungsbeispielen an Hand der Figuren 1-3 0 Figur 1 zeigt einen$Leitungzug 1, 29 der in vier räumlich und elektrisch parallel liegende Teile 3, 4, 5, 6 aufgeteilt isto Durch Auftrennen der einzelnen Leitungsteile (etwa an den Stellen 7,'8 oder 9) kann der elektrische Widerstand des Leitungszugs etwa im Verhältnis 1 : 4 verändert werden. Das Auftrennen kann beispielsweise durch Durchschleifen der Leitungsteile an den Stellen 7, 8 oder 9 erfolgen. Die eingangs angeführte Beschädigung des Trägers und der an den Schliffstellen angrenzenden Leiterteile ist in diesem Fall unbeachtlich, da sie den abgeschalteten Leiterteil und dessen Umgebung betrifft.If certain resistance values are strictly adhered to, it is necessary to partially grind or scrape off the cable runs after they have been manufactured. In this case, however, the support base for the twisted scja; timg is often damaged. In addition, the cable runs easily become detached from the base. innovation There are therefore xfiN-B according to in the printed circuit Leitun, & Cable runs provided, which in several, interconnecting bare line parts are subdivided in such a way that by connecting or disconnecting line parts in the cable run, the electrical resistance of the cable run can be changed optionally. innovation In training of the m; Sa = E are the individual parts of the line arranged spatially parallel to each other and have widened Ende'auf 0 The line parts can then easily go through Solder drops alternatively electrically one behind the other or in parallel be switched. innovation In a simple modification of the 3g, manufacturing according to the individual line parts initially connected to each other and it can be the electrical resistance of the wire pulling through it Separating the individual line parts can be changed. innovation More details of the; S er, give themselves from the following Lowing description of three exemplary embodiments on the basis of Figures 1-3 0 Figure 1 shows a cable line 1, 29 which is divided into four spatially and electrically parallel parts 3, 4, 5, 6 can be changed in a ratio of about 1: 4. The separation can be done, for example, by looping through the line parts at points 7, 8 or 9. The aforementioned damage to the carrier and the conductor parts adjoining the grinding points is irrelevant in this case, since it affects the switched-off conductor part and its surroundings.

Der Leitungszug 10, 11 nach Figur 2 bes, teht ebenfalls aus vier nebeneinander liegenden Leitungsteilen 12, 13, 14, 15"jedoch liegt nur der Leitungsteil 12 herstellungsgemäß von vornherein im Leitungszug 10,11. Die Leitungsteile 13, 14, 15 weisen verbreiterte Enden 16, 17 18 auf, die in einem Abstand von etwa 0, 5 bis 2 mm der Kante 19 des Leitungszuges 10 gegenüberstehen, Die Leitungsteile 13,14,15 können in einfacher Weise dem Leitungszug 12'parallel geschaltet werden, indem man die Lücken zwischen den Enden 16, 17 und 18 und d er Kante 19 mit einem'Löttropfen überbrückt. Diese Anordnung hat den Vorteil, daß zunächst durch Messung die in Einstellung des Widerstands geeignetsten Kombinationen von Leiterteilen ermittelt werden können, worauf an- schließend die jeweiligen Leitungslücken überbrückt werden t Der Leitungszug 20,'21 nach Figur 3 ist durch drei Leiterteile 22 23, 24 zu überbrücken. Die Enden aller dieser Leitungsteile sind verstärkt. Die Leitungsteile 22, 23, 24 können wahlweise parallel oder hintereinander zwischen den Leitungszügen 20,21 geschaltet werden, so daß man eine Widerstandsänderung im Verhältnis 1 : 9 erzeugen kann.The line 10, 11 according to FIG. 2 also consists of four line parts 12, 13, 14, 15 ″ lying next to one another, but only the line part 12 lies in the line 10, 11 from the start according to the manufacturing process. The line parts 13, 14, 15 have widened ends 16, 17, 18, which face the edge 19 of the cable run 10 at a distance of about 0.5 to 2 mm the ends 16, 17 and 18 and the edge 19 with a solder drop bridged. This arrangement has the advantage that the most suitable combinations of conductor parts in setting the resistance can first be determined by measurement, whereupon the respective line gaps are then bridged t The line 20, '21 according to Figure 3 is through three conductor parts 22 23, 24 to be bridged. The ends of all these pipe parts are reinforced. The line parts 22, 23, 24 can optionally be connected in parallel or one behind the other between the lines 20, 21, so that a change in resistance in the ratio of 1: 9 can be generated.

Die angeführten Beispiele stellen nur Grundformen dar ; die Ausführung dieser Formen richtet sich in erster Linie nach den vorgegebenen Platzverhältnissen und Anforderungen in Bezug auf Abgleichbarkeit.The examples given represent only basic forms; execution these forms are based primarily on the given space and requirements related to matchability.

Die genannten Maßnahmen haben sich insbesondere beim Abgleichen von Leitungszügen bewährt, bei denen nur geringe Abweichungen der . Widerstände voneinander zulässig sind, insbesondere bei gedruckten Schaltverbindungen von Pupinspulensätzen. Auch die Widerstandsunterschiede in Spulenwicklungen können mittels der beanspruchten Maßnahmen in der Gesamtanordnung ausgeglichen werden ; bei den Spulen selbst können dann größere Toleranzen in den Widerstandsdifferenzen zugelassen werden. Neuerung Im Rahmen der z werden auch geätzte Schaltungen als ge- druckte Schaltungen angesehen, ohne daß hierdurch die Merkmale Neuerung der E berührt werden. Schutz- 6 4 anspruche 3 Figuren The measures mentioned have proven particularly useful when aligning cable runs with only minor deviations in the. Resistances from one another are permissible, especially in the case of printed circuit connections of Pupin coil sets. The differences in resistance in the coil windings can also be compensated for by means of the measures claimed in the overall arrangement; in the case of the coils themselves, greater tolerances in the resistance differences can then be permitted. innovation In the context of the z, etched circuits are also referred to as printed circuits viewed without affecting the features innovation the E to be touched.
