Title: (EN) A screened electrical device and a process for manufacturing the same
(ZH) 屏蔽的电子器件及其制造工艺
Abstract: front page image
(EN) A protected electrical device having at least one electrical sub-assembly (1) to be protected comprises on at least one (11) of upper and lower surfaces (11, 12), at least a screening layer (2) against the electromagnetic (EM) and radiofrequency (RF) fields emitted by the electrical sub-assembly (1). The screening layer (2) comprises at least a first layer made of soft magnetic material with a high relative permeability ( mu r) larger than 500. The screening layer (2) is placed on substantially the whole surface of said at least one (11) of the upper and lower surfaces (11, 12), except on predetermined regions (1a) of limited area, the electrical connections (8, 9) with external devices being located on at least some of the predetermined regions of limited area.
(ZH)

一种具有至少一个要保护的电子子部件(1)的被保护电子器件,在上和下表面(11、12)的至少一个(11)上至少包括抵抗由电子子部件(1)发出的电磁(EM)和射频(RF)场的屏蔽层(2)。屏蔽层(2)至少包括由高相对磁导率(μr)大于500的软磁性材料制成的第一层。屏蔽层(2)放置在上和下表面(11、12)中至少一个(11)的基本整个表面上,除了在限制区域的预定区域(1a)上之外,与外部器件的电连接(8、9)位于至少一些该限制区域的预定区域上。
