Description

Verpackungsbeutel für Elektronik-Leiterpla ttenPackaging bags for electronic circuit boards

Die Erfindung betrifft einen Verpackungsbeutel für Elektronik-Leiterplatten, bestehend aus zwei an ihren Rändern mindestens teilweise miteinander verschweißten Kunststoff-Folienstücken, die mindestens teilweise elektrisch leitend sind.The invention relates to a packaging bag for electronic circuit boards, consisting of two at their edges at least partially welded together Plastic film pieces that are at least partially electrically conductive.

Die zur Bestückung von Elektronik-Leiterplatten verwendeten elektronischen Bauteile sind häufig so empfindlich, daß sie bereits durch die von außen kommende Spannung zerstört werden können, die durch statische Aufladung entsteht. Dies gilt insbesondere für mit MOS-Bauteilen bestückte Leiterplatten. Um eine statische Aufladung zu verhindern, hat man die Verpackungsbeutel für derartige empfindliche Elektronik-Leiterplatten aus Kunststoffolien hergestellt, die durch einen Zusatz elektrisch leitend gemacht worden sind. Durch diesen Zusatz werden die Folien gefärbt; üblicherweise sind diese elektrisch leitenden Folien schwarz gefärbt und deshalb nicht durchsichtig, so daß eine Kontrolle der Leiterplatten und dor darauf angebrachten elektronischen Bauteile ohne Öffnen des Verpakkungsbentels nicht möglich war. Beschädigungen der Elektronikbauteile und der Leiterplatten konnten deshalb entweder nicht sofort festgestellt werden, oder die Verpackungsbeutel mußten unmittelbar nach dem Empfang geöffnet werden, so daß die Gefahr einer späteren Verunreinigung oder Beschädigung bestand.The electronic ones used to assemble electronic circuit boards Components are often so sensitive that they can already be removed from the outside Voltage caused by static electricity can be destroyed. this applies especially for printed circuit boards equipped with MOS components. About static electricity to prevent, you have the packaging bags for such sensitive electronic circuit boards made of plastic films, which are made electrically conductive by an additive have been. The foils are colored by this addition; usually these are electrically conductive foils colored black and therefore not transparent, so that an inspection of the printed circuit boards and the electronic components attached to them was not possible without opening the packaging bag. Damage to the electronic components and so the PCB couldn't either noticed immediately or the packaging bags had to be opened immediately upon receipt so that there was a risk of later contamination or damage.

Aufgabe der Erfindung ist es daher, einen Verpackungsbeutel der eingangs genannten Art so auszugestalten, daß einerseits eine Beschädigung der Elektronikbauteile durch statische Aufladung zuverlässig verhindert wird, andererseits aber eine Sichtkontrolle der Leiterplatte und der Elektronikbauteile ohne ein Öffnen des Verpackungsbeutels möglich ist.The object of the invention is therefore to provide a packaging bag of the initially mentioned named type so that, on the one hand, damage to the electronic components is reliably prevented by static charging, but on the other hand a visual inspection the circuit board and the electronic components without opening the packaging bag is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Verpackungsbeutel aus einem elektrisch leitenden Kunststofffolienstück und einem durchsichtigen Kunststoff-Folienstück besteht, die an ihren Rändern miteinander verschweißt sind.This object is achieved according to the invention in that the packaging bag made of an electrically conductive piece of plastic film and a transparent piece of plastic film exists, which are welded together at their edges.

Die elektrisch leitende, üblicherweise schwarz eingefärbte Folie kommt mit der Lötseite der Leiterplatte in Berührung und schließt dadurch alle Anschlüsse kurz, so daß eine statische Aufladung und die Einwirkung von unzulässig hoher Spannung auf die Elektronikbauteile verhindert wird. Durch die durchsichtige Transparentfolie ist die andere Seite der Leiterplatte mit den darauf angebrachten Elektronikbauteilen sichtbar, so daß eine Kontrolle ohne Öffnen des Verpackungsbeutels möglich ist.The electrically conductive film, usually colored black, comes in with the solder side of the circuit board in contact and thereby closes all connections short, so that static electricity and the effects of unacceptably high voltage on the electronic components is prevented. Through the transparent film is the other side of the circuit board with the electronic components attached to it visible, so that it can be checked without opening the packaging bag.

Zweckmäßigerweise besteht das elektrisch leitende Kunststoff-Folienstück aus vorzugsweise schwarz eingefärbter, elektrisch leitender Polyurethanfolie, während das durchsichtige Kunststoff-Folienstück aus Polyäthylenfolie ohne Gleitmittelzusatz besteht. Dadurch wird die Verschweißbarkeit der beiden unterschiedlichen Folien verbessert.The electrically conductive piece of plastic film is expediently made from preferably black colored, electrically conductive polyurethane film, while the transparent piece of plastic film made of polyethylene film without added lubricant consists. This increases the weldability of the two different foils improved.

Die Erfindung wird nachfolgend an einem AusfUhrungsbeispiel näher erläutert, das in der Zeichnung dargestellt ist.The invention is explained in more detail below using an exemplary embodiment explained, which is shown in the drawing.

Die Zeichnung zeigt in perspektivischer Darstellungsweise einen noch an einem Rand offenen Verpackungs-Flachbeutel 1 für eine Elektronik-Leiterplatte 2, die mit nur andeutungsweise dargestellten Elektronik-Bauteilen 3 bestückt ist, von denen beispielsweise einige MOS-Bauteile sind. Der deutlichen Darstellung halber ragt die Leiterplatte 2 in der Zeichnung noch etwas aus dem Verpackungsbeutel 1 heraus; zum vollständigen Verpacken wird die Leiterplatte 2 völlig in den Verpackungsbeutel 1 hineingeschoben, dessen Öffnung anschließend verschlossen werden kann.The drawing shows in a perspective representation a Flat packaging bag 1 still open at one edge for an electronic circuit board 2, which is equipped with only hinted at electronic components 3, some of which are MOS components, for example. For the sake of clarity the printed circuit board 2 still protrudes somewhat from the packaging bag 1 in the drawing out; for complete packaging, the circuit board 2 is completely placed in the packaging bag 1 pushed in, the opening of which can then be closed.

Der Verpackungsbeutel 1 besteht aus einem elektrisch leitenden Kunststoff-Folienstück 4 aus Polyurethanfolie, die zur Erzielung der elektrischen Leitfähigkeit mit einem die Folie schwarz färbenden Zusatz versehen ist. Das elektrisch leitende Folienstück 4 berührt die die Lötstellen aufweisende Unter seite der Leiterplatte 2 und schließt dort alle metallischen Teile elektrisch kurz. Die Oberseite (Sichtseite) des Verpackungsbeutels 1 wird von einem durchsichtigen Kunststoff-Folienstück 5 gebildet, das an seinen drei Rändern mittels einer Schweißnaht 6 mit dem elektrisch leitenden Folienstück 4 verbunden ist. Das durchsichtige Folienstück 5 besteht aus Polyäthylenfolie, die zur Verbesserung der Schweißbarkeit ohne Gleitmittelzusatz ausgeführt ist.The packaging bag 1 consists of an electrically conductive piece of plastic film 4 made of polyurethane film, which is used to achieve electrical conductivity with a the film is provided with a black coloring additive. The electrically conductive piece of film 4 touches the underside of the printed circuit board 2, which has the solder points, and closes there all metallic parts are electrically short. The top (visible side) of the packaging bag 1 is formed by a transparent piece of plastic film 5, which is attached to his three edges by means of a weld 6 with the electrically conductive foil piece 4 is connected. The transparent piece of film 5 consists of polyethylene film, which is designed to improve weldability without the addition of lubricant.

Wie in der Zeichnung angedeutet, kann die dieElektronikbauteile 3 tragende Oberseite der Leiterplatte 2 durch das durchsichtige Folienstück 5 hindurch kontrolliert werden, ohne daß der Verpackungs-Flachbeutel 1 geöffnet werden müßte.As indicated in the drawing, the electronic components 3 load-bearing top of the circuit board 2 through the transparent piece of film 5 therethrough can be checked without the flat packaging bag 1 having to be opened.

Das schwarz gefärbte Folienstück 4 kann bedruckt sein, beispielsweise mit Hinweisen für die Behandlung der verpackten Leiterplatte und/oder mit Angaben über die Beschaffenheit, Herkunft, Bestimmung usw. der verpackten Leiterplatte'.' An dem im dargestellten Zustand noch offenen Rand wird der Verpackungsbeutel ebenfalls zugeschweißt, so daß die Leiterplatte 2 in dem Yerpackungsbeutel 1 hermetisch verschlos3en ist.The black-colored piece of film 4 can be printed, for example with instructions for handling the packaged circuit board and / or with information about the nature, origin, destination, etc. of the packaged circuit board '.' The packaging bag is also placed on the edge that is still open in the state shown welded shut so that the circuit board 2 in the packaging bag 1 is hermetically sealed is.
