The invention relates to a process and an apparatus for producing a molded fiber article. The process comprises the steps of —dissolving fibrous materials in water to form a fibrous material suspension in a pulper, —removing moisture from the fibrous material suspension by pressing to form a molded fiber article in a mold and/or —drying the molded fiber article by supplying heat, —demolding the molded fiber article from the mold. The process is characterized by the feature whereby, in mold drying of the molded fiber article in the mold, a moisture content of the molded fiber article of not more than 10% by weight or not more than 7.5% by weight or not more than 5% by weight is achieved.

Process and apparatus for producing a molded fiber article

A module for a tester for the testing of circuit boards is described. Such testers have a basic grid on which an adapter and/or a translator may be arranged in order to connect contact points of the basic grid with circuit board test points of a circuit board to be tested. The module comprises a support plate and a contact board. The contact board is formed by a rigid circuit board section which is described as the basic grid element, and at least one flexible circuit board section. Provided on the basic grid element are contact points which each form part of the contact points of the basic grid. The basic grid element is mounted at an end face of the support plate, and the flexible circuit board section is bent in such a way that at least part of the other section of the contact board is parallel to the support plate. Each of the contact points of the basic grid element is in electrical contact with conductor paths running in the contact board and extending from the basic grid element into the flexible circuit board section.

Module for test device for testing circuit boards

The invention relates to a method and a device for the testing of noncomponented circuit boards. The method according to the invention is used to determine deviations of circuit board test points of a series of circuit boards from the CAD data relating to these circuit boards, by scanning the surface of the circuit board by an imaging method and subjecting this image to automatic image analysis so that it may be compared with the CAD data. The CAD data are then suitably corrected so that, with the aid of the corrected CAD data, the circuit board may be tested in a finger tester, with test fingers of the finger tester being controlled on the basis of the deviations found.

Method and device for testing of non-componented circuit boards

An apparatus and a method for the testing of circuit boards, together with a test probe for this apparatus and this method, in which the contact tips of a test finger of a finger tester are monitored during the testing process by an optical detection device and their movement, at least when approaching a part of the circuit board test points of a circuit board to be tested, is corrected on the basis of the result determined by the optical detection device in such a way that the contact tip makes reliable contact with the circuit board test point concerned. The correction data hereby obtained may be used in the calculation of calibration data.

Apparatus and method for the testing of circuit boards, and test probe for this apparatus and this method

The invention relates to a circuit board testing method, wherein an array of several circuits of a circuit board are short-circuited and further circuits are short-circuit tested by applying a high test voltage relative to said array of circuits, as a result of which the number of tests, which are normally highly time-intensive due to the high voltages, is drastically reduced since the further circuits do not need to be tested discretely relative to each circuit of the circuit array.

Circuit board testing method

A method of testing an electrical conductor assembly having a plurality of networks is divided into a first test routine and in further test routines. A conductor assembly is tested in each test routine. In a first test routine, a field test for detecting short-circuits between the individual networks and a resistance test for detecting open-circuits in said networks are implemented. From the data sets resulting from the field test, complex conductances are determined between at least one antenna employed in the field test and the tested networks, which are used as reference conductances for the further test routines. In the further test routines short-circuits between the networks and/or open-circuits in the networks are detected by sensing a complex actual conductance between each network and at least one antenna and by comparing the actual conductance to the reference conductance. In addition the invention relates to an apparatus for implementing the method.
