发明名称 Electronic printed-circuit board for electronic devices, especially communications terminals
摘要 The aim of the invention is to improve the modular assembly technique used for assembling electronic printed-circuit boards (FBG1, FBG2) for electronic devices in order to incorporate the printed-circuit boards in electronic devices with electronic printed-circuit boards of the type mentioned above more flexibly in terms of the printed-circuit board material, in accordance with the respective field of application, size and weight requirements and manufacturing costs of the devices. To this end, the electronic devices are modularly assembled in terms of the printed-circuit board construction, with at least two printed-circuit boards (FBG1, FBG2) consisting of different materials with different temperature and length-related expansion coefficients. The individual printed-circuit boards are fixed with electroconductive fixing means (LB) in such a way that when they are in their fixed state, inner electrical, mechanically stable connections are provided between the two printed-circuit boards, concealed by the printed-circuit boards, in an intermediate assembly gap (MZR) formed by the printed-circuit boards. The different temperature and length-related expansion coefficients associated with the materials ensure that there are no material stresses that could destroy the connections.
