Abstract

The invention discloses a patch-type network transformer and a manufacturing method thereof. The patch-type network transformer comprises a packaging substrate unit, a signal conditioning module and packaging glue, wherein electrodes are arranged on the upper surface and the lower surface of the packaging substrate unit; the signal conditioning module is attached to the packaging substrate unit; and the packaging glue is injected and molded on the packaging substrate unit and packages the signal conditioning module therein. The patch-type network transformer disclosed by the invention is simple and convenient to manufacture and good in quality; and the production efficiency and the qualified rate of a product can be greatly improved.

Description

technical field [0001] The invention relates to a network transformer, in particular to a patch type network transformer and a manufacturing method thereof. Background technique [0002] The signals of electronic communication equipment are easily interfered by various conduction and radiation noises during transmission, and people usually use filter devices to reduce such interference. Such as network transformers, which are mainly used in various Ethernet devices, such as high-performance digital switches, routers, servers and other digital devices. Network transformers mainly have the functions of signal transmission, impedance matching, waveform restoration, signal clutter suppression and high voltage isolation. [0003] The Network Transformer module is an indispensable part of the network card circuit. Its basic components mainly include an isolation transformer (Pulse Transformer), a common mode filter (Common Mode Filter), an intermediate tap capacitor, an autotrans...
