5.0 Hahlbchrer zum entfernen mehrbeiniger, elektronischer Bauteile die in Leiterplatten eingelötet sind.5.0 Hahlbchrer for removing multi-legged electronic components which are soldered into printed circuit boards.
Die Erfindung letrifft einen Hohlbohrer mit dem man schon lereits eingelötet mehrbeinige elektronische Bauteile problemlos von der Leiterplatte wieder entfernen kann, 5.1 ohne die Leiterplatte oder das Bauteil zu leschädigen. The invention meets a hollow drill with which one is already learning Soldered in multi-legged electronic components easily from the circuit board 5.1 without damaging the circuit board or the component.
Der Hohlbohrer kann in den Bereichen der Elektronikbrange eingesetzt werden, deren Aufgabe es ist, defekte elektr. Bauteile auszuwechseln. Die Handhabung ist ortsunabhangig, ideal fün den Seruicebereich. The hollow drill can be used in the fields of electronics whose task is to repair defective electr. Replace components. The handling is location-independent, ideal for the service area.
5.2 Zur Zeit sind mir drei Verfahren bekannt, die gleichen Zweck erfüllen können. Das eine ist ein Zinnbad indem alle Lötstellen zur gleichen Zeit aur Schmelzung gebracht werden.5.2 I am currently aware of three processes that serve the same purpose can. One is a tin bath in which all solder joints are melted at the same time to be brought.
Das Bauteil kann dann heraus genommen werden. The component can then be removed.
Das zweite Verfahren, daß mir bekannt ist, ist eine 5.3 Komlination von Lötkolben und Vacuumpumpe. Nachdem man mit dem Lötkollen das Lot zur Schmelze gebracht hat, betatigt man die Vacuumpumpe die das flüssige Lötzinn alsaugt. The second method that I know of is a 5.3 comlination of soldering iron and vacuum pump. After you melt the solder with the soldering bob has brought, the vacuum pump is actuated, which sucks the liquid solder.
Das dritte Verfahren ist ein Einsatz für den Lötkolben, der mit der Bauart des zu entfernenden Bauteils überein-5.4 stimmen muß, mit dem dann alle Beinchen zur gleichen Zeit erwärmt werden. The third method is an insert for the soldering iron that comes with the The type of construction of the component to be removed must match-5.4, with which then all the legs be heated at the same time.
Die ersten beiden Verfahren sind technisch sehr aufwendig. The first two methods are technically very complex.
und daher sehr kostenintensiu. Wobei das zuerst beschriebene Gerät noch nicht einmal transportabel ist. and therefore very cost-intensive. Whereby the device described first is not even transportable.
5.5 Das dritte Verfahren ist praktisch sehr schlecht durchzuführen. Abgesehen davon, daß man für jedes Bauteil das passende Werkzeug benötigt, ist es unmöglich alle Beinchen gleichzeitig zu erwarmen, wenn nur eines ein wenig verbogen ist.5.5 The third method is very difficult to carry out in practice. Apart from the fact that you need the right tool for every component, it is impossible to warm all legs at the same time if only one is bent a little is.
5.6 Der Erfindung liegt die Aufgabe zugrunde, daß Problem, eingelötete, mehrbeinige, elektronische Bauteile auszuwechseln ; einfach, preisgünstig und ortsunabhängig zu lösen.5.6 The invention is based on the problem that the problem, soldered, replace multi-legged electronic components; simple, inexpensive and independent of location to solve.
5. Beschreibung 5.7 Diese Aufgabe wird mit dem unter Anspruch 1 beschriebenen Bohrer im Zusammenhang mit einer handelsüblichen Feinbohrmaschine oder einem Lötkolben erfüllt.5. Description 5.7 This task is described under claim 1 with that Drill in connection with a commercially available fine drill or a soldering iron Fulfills.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das bisherige Problem, auswechseln 5.8 mehrbeiniger elektronischer Bauteile problemlos, unabhängig von der Bauant des Bauteils, ohne großen Aufwand und von allem sehr preisgünstig gelöst ist. The advantages achieved with the invention are in particular: that the previous problem, replace 5.8 multi-legged electronic components problem-free, regardless of the builder of the component, without great effort and from everything is solved very cheaply.
Ein Ausführungsbeispiel der Erfindung ist auf dem Blatt 2 der Zeichnungen dargestellt und wird wie im folgenden naher 5.9 beschrieben. An embodiment of the invention is on sheet 2 of the drawings and is described as 5.9 below.
Vor dem bohren mit dem Hohlbohrer ist es zweckmäßig, von allen Anschlüssen des zu entfernenden Bauteils, mit Hilpe eines Lötkolbens und einer Entlötpumpe, soviel wie möglich von dem vorhandenen Lötzinn abzusaugen. Ist dieses getan, 5.10 so spannt man den Hohlbohrer (3) in eine handelsübliche Feinbohrmaschine (4). Der hohlbohrer wird so angesetzt, daß er ein Anschlußbein des zu entfernenden Bauteils (1) umschließt. Betätigt man nun die Feinbohrmaschine, so wird das Anschlußbeinchen ganz sauber von der leiterplatte (2) 5.11 getrennt. Dieser Vongang muß dann bei jedem Anschlußbeinchen vollzogen werden, bis das Bauteil vollständig von der Leiterplatte gelöst ist. Before drilling with the hollow drill bit, it is advisable to remove all connections of the component to be removed, with the help of a soldering iron and a desoldering pump, suck up as much of the solder as possible. Once this is done, 5.10 the hollow drill (3) is clamped in a commercially available fine boring machine (4). Of the Hollow drill is positioned so that it becomes a connecting leg of the component to be removed (1) encloses. If you now operate the fine boring machine, the terminal pin becomes very cleanly separated from the circuit board (2) 5.11. This Vongang must then with Each lead is completed until the component is completely removed from the circuit board is resolved.
Auf Blatt 1 der Zeichnungen sehen Sie zwei Möglichkeiten des Hohlbohrers mit dem ein handelsülliches IC von der Leiterplatte getrennt werden kann. On sheet 1 of the drawings you can see two options for the hollow drill with which a commercially available IC can be separated from the circuit board.
