Abstract
The invention provides a high-density electronic plate base which comprises a support, a supporting leg and a strong magnetism lining. The longitudinal section of the support is of a wide-end-down cavity structure. The supporting leg is fixed at the center of the upper surface of the support. The supporting leg is provided with an upper surface in contact with a supported piece. The upper surface is a horizontal plane. The surface area of the horizontal plane is far smaller than the bottom area of the supporting leg. The strong magnetism lining is placed in a support cavity. The strong magnetism lining and the wall face of the support cavity are attached to form a uniform magnetic field. The high-density electronic plate base is machined at a machining center through stainless steel, the distance between the bottom and the top is only 1 mm, a protected device can be effectively avoided, a strong magnet is embedded to the bottom of the high-density electronic plate base so that locating can be carried out at any place, and accordingly an electronic plate is supported conveniently and effectively.
Description
Technical field
The present invention relates to a kind of high density electron plate base, belong to electronic technology field.
Technical background
Along with the house show of electronic industry, the Continual Improvement of surface mounting technology, the continuous densification of components and parts, BGA Package, wafer-level package, frequentization that the similar device such as multi-chip module uses.Such devices solves the demand that more and more densification is installed on surface, but meanwhile also brings the reinforcement of maintenance difficulty.So there is the maintenance special equipment of a series of such devices on the market.SRT-1800 has perfect function because of it, becomes outstanding person in the industry, but its support system is inapplicable to part high density electron plate, can impact during maintenance to other devices.Conventional support is formed on a support by several steel bar strings, is then placed directly on steel bar by the electron plate that will keep in repair, electron plate is supported.Such supporting construction can accomplish good support to general electron plate, but when high density or extra small electron plate just dying, because the contact-making surface of whole steel bar is too wide, is difficult to avoid device.When next is the spacing of inadequate two steel bars when plate is less, cannot support at all.
Summary of the invention
In order to overcome above problem, the invention provides a kind of high density electron plate base, the above defect can be solved, the support of high density electron plate and extra small electron plate can be solved; Reduce the device off normal and short circuit that cause because support is bad.
For solving above technical problem, technical scheme provided by the invention is as follows: described high density electron plate base comprises supporting seat, supporting leg and strong magnetic liner, and the longitudinal section of described supporting seat is low wide and up narrow cavity structure; Supporting leg is fixed on the upper surface center of supporting seat, and supporting leg has the upper surface contacted with by strutting piece, and this upper surface is horizontal plane, and the surface area of this horizontal plane is much smaller than supporting leg floor space; Described strong magnetic liner is placed with in supporting seat cavity; Strong magnetic liner and supporting seat cavity wall are fitted, and form uniform magnetic field; The lower surface of supporting leg is less than the upper surface of strong magnetic liner.
Further, described strong magnetic liner is magnet.
Further, the cross section of described supporting seat is square or circular, and longitudinal section is isosceles trapezoid.
Further, the cross section of described supporting leg is square or circular, and longitudinal section is isosceles trapezoid.
This high density electron plate base that the present invention relates to, can solve the problem that high density electron plate not easily supports.
Accompanying drawing explanation
Fig. 1 is high density electron plate base front view of the present invention;
Fig. 2 is the vertical view of high density electron plate base;
1-supporting seat; 2-supporting leg; 3-magnet; 31-supporting leg upper surface.
Embodiment
As shown in Figure 1-2, the strong point being only Portable support shown in figure, this support at least has three, could will be propped up by strutting piece, is to strengthen the stability supported, and can use four or more.
The concrete structure of high density electron plate base comprises supporting seat 1, supporting leg 2 and magnet, and magnet 3 also can be cavity shape, fits with supporting seat 1 cavity wall, forms uniform magnetic field.
The lower surface of supporting leg 2 is less than the upper surface of magnet 3, in order to avoid magnetic field is blocked by supporting leg.
The cross section of supporting seat 1 is square or circular, and longitudinal section is isosceles trapezoid.
The cross section of supporting leg 2 is square or circular, and longitudinal section is isosceles trapezoid.
The wall thickness of supporting seat 1 cavity both sides is 1mm.
Supporting seat 1 cavity upper end thickness is 3mm.
The cross section of supporting leg 2 upper surface 31 is square, and width is 1mm.
This high density electron plate base provided by the invention; stainless steel is adopted to process at Mechanical Processing Center; bottom dome only has 1mm; can effectively avoid claimed device; in the bottom of high density electron plate base by inlaying strong magnetic; can locate Anywhere again, thus reach convenient effective support electron plate.
Embodiment of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
