Abstract
The utility model discloses a kind of high temperature load bearing board that surface topography accurately controls, including cuboid plate body, plate body is rough surface by the surface that length and width forms, and the surface roughness of the rough surface is 2 ~ 10 μm, plane warping degree≤5um/100mm.The utility model smooths the optimization of technique by the optimization and high temperature of surface roughening treatment process compared with traditional technology, to surface roughness and plane warping degree carry out it is significantly more efficient accurately control, the characteristic electron for improving electronic component has obvious effects on.
Description
Technical field
The utility model belongs to fire resisting material field, and in particular to a kind of high temperature load bearing board that surface topography accurately controls.
Background technology
Electronic component is the basis of electronic information industry, wide market.The firing of electronic component is more demanding, in reality
In the production process of border, the electrical characteristic of electronic component should be ensured, ensure the angularity of electronic component again, because angularity is
One of the key factor of component installation capability, performance and heat dissipation performance etc. is influenced, angularity numerical fluctuations are larger, can cause
Product is unqualified.So the requirement for the high temperature carrying tool load bearing board of electronic component is very high, high temperature load bearing board surface will have
The bonding situation for occurring under high temperature with electronic component does not occur for certain roughness, the permeability for increasing contact surface；Separately
One side high temperature load bearing board will have good flatness to ensure that product angularity can be in the range of control.
To meet the requirement of electronic component high temperature firing, develops and a kind of holding burning with the high temperature that surface topography accurately controls
Plate shows important especially.
Invention content
Goal of the invention：The purpose of this utility model is that in view of the deficiencies of the prior art, it is accurate to provide a kind of surface topography
The high temperature load bearing board of control.
Technical solution：In order to reach foregoing invention purpose, what the utility model was specifically performed by：A kind of surface shape
The high temperature load bearing board that looks accurately control, including cuboid plate body, plate body is rough surface by the surface that length and width forms, described
The surface roughness of rough surface be 2 ~ 10 μm, plane warping degree≤5um/100mm,（Any 100mm length directions sticks up in plane
Curvature）.
Further, the height of the plate body is 1 ~ 6mm, preferably 2mm.
Wherein, the plate body material is aluminium oxide.
Further, preferably 2 ~ 5 μm of the surface roughness of the plate body rough surface.
Further, the plate body rough surface plane warping degree preferably≤3um/100mm.
Advantageous effect：The utility model is comforted compared with traditional technology by the optimization and high temperature of surface roughening treatment process
The optimization of flat technique, to surface roughness and plane warping degree carry out it is significantly more efficient accurately control, for improving electronic component
Characteristic electron have obvious effects on.
