Brief description of the drawings
Fig. 1 is the structural representation of Novel heating testboard in an embodiment.
Specific embodiment
For the ease of understanding the utility model, the utility model is more fully retouched below with reference to relevant drawings
State.First-selected embodiment of the present utility model is given in accompanying drawing.But, the utility model can come real in many different forms
It is existing, however it is not limited to embodiment described herein.On the contrary, the purpose for providing these embodiments is made to public affairs of the present utility model
Open content more thorough comprehensive.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with technology of the present utility model is belonged to
The implication that the technical staff in domain is generally understood that is identical.It is herein to be in term used in the description of the present utility model
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
The arbitrary and all of combination of one or more related Listed Items.
Fig. 1 is the structural representation of heating testboard in an embodiment.Heating testboard include base plate 10, heater 20,
Thermal conductive silicon rubber cushion 30, test board 50 and partiting thermal insulation filler 60.Heater 20 is tested on base plate 10 as heating
The thermal source of platform.In the present embodiment, heater 20 is heater strip (heating wire)；In other embodiments, heater 20 can also
Using other known heaters of this area, such as ptc heater, electromagnetic heater etc..
Thermal conductive silicon rubber cushion 30 is attached between heater 20 and test board 50, used as between heater 20 and test board 50
Thermal conductive insulator, for the heat that heater 20 is produced to be conducted to test board 50, and play heater 20 and test board 50 it
Between insulating effect.Thermal conductive silicon rubber cushion usually using common silica gel as raw material, thermal conductive silicon rubber cushion have good insulating properties,
Mechanicalness, sealing, difficult deformation, thus thermal conductive silicon rubber cushion be also able to widely be applied.It is good in order to ensure
Insulating properties, thermal conductive silicon rubber cushion 30 uses thicker thermal conductive silicon rubber cushion.Can specifically be produced according to test board 50 and heater 20
Voltage/current selects the thickness of thermal conductive silicon rubber cushion 30.
Thermal conductive silicon rubber cushion 30 is connected to form enclosed construction with base plate 10, and cavity is formed with enclosed construction, and heater 20 sets
In in cavity.
Partiting thermal insulation filler 60 is filled in cavity.Due to base plate 10 be not required to it is to be heated, so by will be heat-insulated exhausted
Edge filler 60 is filled between base plate 10 and heater 20 and fills up the cavity around heater 20 to strengthen heating test
The overall structural strength of platform.Wherein in one embodiment, the material of partiting thermal insulation filler 60 is asbestos.
Test board 50 is tested on thermal conductive silicon rubber cushion 30 for measuring targets (such as chip).Test board 50
On be provided with test circuit etc. for realizing the part of test function, the heat that heater 20 is produced is passed by thermal conductive silicon rubber cushion 30
Be directed on test board 50 so that the object under test being placed on test board 50 be heated to it is desirable that test temperature (such as 140
Degree Celsius).
Above-mentioned heating testboard, sets the thermal conductive silicon rubber cushion 30 of thickening as heat conduction between heater 20 and test board 50
Insulating barrier.On the premise of fully insulation is ensured, unnecessary intermediate heat transfer layer is eliminated, improve the thermal efficiency, be conducive to section
Can be environmentally friendly, cost is reduced, reduce difficulty of processing.
Wherein in one embodiment, base plate 10 uses stainless steel, to obtain good durability and corrosion resistance
Energy.Also heated by heater 20 because we are not intended to base plate 10, therefore the structure of connecting bottom board 10 and thermal conductive silicon rubber cushion 30
Material can use heat-insulating material.
Wherein in one embodiment, the surface of thermal conductive silicon rubber cushion 30 scribbles heat-conducting silicone grease.Heat-conducting silicone grease is usually to have
Machine silicone is primary raw material, adds heat-resisting, excellent thermal conductivity material, the heat-conducting type organosilicon smectic compound being made.
In the present embodiment, the bottom surface of thermal conductive silicon rubber cushion 30 and top surface are coated with heat-conducting silicone grease.
The general degrees centigrade of thermal conductive silicon rubber cushion heatproof 280, the degrees centigrade of heat-conducting silicone grease heatproof 250, therefore it is above-mentioned
Heating testboard can be used normally below 250 degrees Celsius.And it is Celsius to be usually no more than 140 when heating testboard high temperature test
Degree, thus it is completely out of question at heat-resisting aspect.
Heat-conducting silicone grease can be filled in micro- between thermal conductive silicon rubber cushion 30 and heater 20, thermal conductive silicon rubber cushion 30 and test board 50
In small space, further strengthen the uniformity of heat conduction.After tested, the temperature difference maximum of each point of test board 50 is no more than in heating process
5 degrees Celsius, more be may remain within 2 degrees Celsius in test process.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore can not be interpreted as the limitation to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
Protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
