Abstract

The present invention relates to a printed circuit board for mobile telephones, which has large-area components on at least one side, which are connected to the printed circuit board in a form-fitting or material-locking manner. To stabilize the printed circuit board, at least one frame (2) receiving a large component (4) is firmly connected to the printed circuit board (1).

Description

  • The present invention relates to a circuit board for Mobile phones, which have large-area components on at least one side, which are positively or materially connected to the circuit board.
  • Printed circuit boards of this type have the most cell phones, usually on one side these circuit boards z. B. RF modules are arranged and on the other side of the circuit board z. B. an LCD module or components the keyboard are arranged.
  • The constant reduction in device volume in future Generations of mobile phones are used among other things of printed circuit boards with a smaller thickness and therefore for use of printed circuit boards, which have a reduced mechanical resilience have, or where it is under constant load to an elevated Deflection is coming.
  • If on the side of the circuit board, on which the RF assemblies are arranged, umbrella frames are provided, which over the whole area extend the circuit board, these screen frames provide a certain stability the circuit board, so no additional stabilization measures required are.
  • But lately there have been some Cases have passed no yourself over the whole area of the printed circuit board extending screen frame, which in individual sections are subdivided to use, but there are individual assemblies with separate umbrella frames. These umbrella frames extend each other only about small surfaces the PCB side and are not interconnected. In In this case, the stability of the circuit board is no longer constant.
  • In these cases it has already been suggested that in the area of large area components stiffeners are provided in the side areas of the circuit board become. Due to the intended partial stiffening of the circuit board in critical areas, d. H. in the immediate vicinity of the vulnerable Components, bending of the circuit board is greatly reduced and so an unintentional detachment of these large components prevented. This solution leads again to a larger space requirement, which can be disadvantageous with miniaturization.
  • Object of the present invention is to specify a circuit board of the type mentioned at the beginning, which, even with a small circuit board thickness, or cohesive Connection of large components guaranteed with the circuit board.
  • This task is mentioned at the beginning PCB loosened by that at least one is a large area component receiving frame is firmly connected to the circuit board.
  • The advantage of the solution according to the invention is in that one and the same component, the frame, both for Stiffening of the circuit board as well as to accommodate the large component serves what opposite usual solutions leads to a smaller space requirement.
  • Further expedient configurations of the printed circuit board according to the invention result from the subclaims and from the following description of an embodiment based on the attached Drawing.
  • Show in the drawing
  • 1 2 shows a perspective illustration of a printed circuit board according to the invention with a frame firmly attached to it,
  • 2 an exploded view of the in 1 illustrated circuit board and a large-area component, and
  • 3 a representation of the circuit board shown in Figure with a large component attached to it.
  • 1 shows a circuit board 1 with a frame attached according to the invention z. With the frame 2 for holding a large-area component, it can be, for example, a display holder. This frame, or this display holder 2 can on the circuit board 1 be soldered on.
  • This is the display holder 2 formed such that the in the longitudinal direction of the circuit board 1 extending side parts have an L-shaped profile, whereby bending of the circuit board can be reliably prevented.
  • The display bracket 2 thus serves once to stabilize the circuit board and at the same time also serves to accommodate a large-area component, in the exemplary embodiment shown for accommodating a display module 4 ,
  • Here is the display bracket 2 and the display module 4 designed so that the two parts can be locked together. For this are in the display holder 2 recesses 3 and on the display module 4 snap hooks 5 intended.

Claims (4)

  1. Printed circuit board for mobile phones, which has at least on one side large-area components which are connected to the printed circuit board in a form-fitting or material-locking manner, characterized in that at least one large component ( 4 ) receiving frame ( 2 ) firmly with the circuit board ( 1 ) connected is.
  2. Printed circuit board according to claim 1, characterized in that the frame ( 2 ) on the circuit board ( 1 ) is soldered on.
  3. Printed circuit board according to claim 1 or 2, characterized in that at least the outer in the longitudinal direction of the printed circuit board ( 1 ) extending side parts of the frame ( 2 ) have an L-shaped profile.
  4. Printed circuit board according to one of the preceding claims, characterized characterized in that the frame serves as a display holder for a display module, being the display bracket and the display module are designed so that they can be locked together are.
