Description
Technical field
The utility model is related to a kind of detection instruments, and in particular to a kind of pcb board thickness detection instrument.
Background technology
Each client has different requirements to the tolerance of pcb board thickness, need to do each plate thickness specification requirement the upper limit and under
The plate thickness size management and control of limit, conventional micrometer efficiency is too slow, measures trouble, and error is too big.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is a kind of simple in structure, and measure it is convenient,
It is greatly improved the measurement accuracy of pcb board thickness and the pcb board thickness detection instrument of efficiency.
The technical solution of the utility model is as follows：
A kind of pcb board thickness detection instrument, including steel bar, the side of the steel bar offers a upper limit by precision milling machine
It is worth deep trouth and a lower limiting value deep trouth, for detecting pcb board thickness, the upper limit value is deep for the upper limit value deep trouth and lower limiting value deep trouth
The width of slot is the maximum gauge that pcb board allows, and the width of the lower limiting value deep trouth is the minimum thickness that pcb board allows, described
The thickness of upper limit value deep trouth and lower limiting value deep trouth has surveyed value according to the range that pcb board thickness allows with accurate calliper.
Further, in the above-mentioned technical solutions, the width of the upper limit value deep trouth be 0.93mm, the lower limiting value deep trouth
Width be 0.87mm.
Further, in the above-mentioned technical solutions, the steel bar is rectangle.
Further, in the above-mentioned technical solutions, the upper limit value deep trouth is parallel with lower limiting value deep trouth set on described rectangular
In one long side of shape steel bar.
Further, in the above-mentioned technical solutions, the upper limit value deep trouth is identical with the depth of lower limiting value deep trouth.
Relative to the prior art, the beneficial effects of the utility model are：The utility model is a kind of special to PCB circuit board
Industry tolerance measurement tool can carry out thickness management and control according to the bound tolerance of customer requirement to reach customer requirement, use
When, only pcb board need to be put into upper limit value deep trouth or lower limiting value deep trouth i.e. can detect PCB it is whether qualified, it is not only easy to use, but also
Same fixture can ensure that PCB measures the consistency and precision of thickness, improve thickness measuring efficiency.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refering to Figure 1, a kind of pcb board thickness detection instrument of the utility model, rectangular including rectangular steel bar 1
One long side of shape steel bar 1 offers a upper limit value deep trouth 2 and a lower limiting value deep trouth 3, upper limit value by the way that precision milling machine is parallel
Deep trouth 2 is identical with the depth of lower limiting value deep trouth 3, and the upper limit value deep trouth 2 and lower limiting value deep trouth 3 are used to detect pcb board thickness, upper limit value
The width of deep trouth 2 is the maximum gauge that PCB plates allow, and the width of lower limiting value deep trouth 3 is the minimum thickness that pcb board allows, the upper limit
The thickness of value deep trouth 2 and lower limiting value deep trouth 3 has surveyed value according to the range that pcb board thickness allows with accurate calliper.
In the present embodiment, the margin of tolerance of pcb board is 0.87-0.93 (mm), and the width of the upper limit value deep trouth 2 is set
For 0.93mm, the width of the lower limiting value deep trouth 3 is set as 0.87mm.In use, pcb board need to be only put into upper limit value deep trouth 2
Or whether the i.e. detectable PCB of lower limiting value deep trouth 3 qualified, lower limiting value deep trouth 3, which is inserted, does not enter then for OK, more than 0.87mm just it is slotting not into
It goes, is then anti-NG；And upper limit value deep trouth 2 is inserted then as OK, is likely to less than 0.93mm so slotting that enter, and is then anti-NG.
It ensure that PCB measures the consistency and precision of thickness, and the utility model uses simply by same fixture measurement
It is convenient, it is more efficient than conventional thickness measuring, it is a kind of to PCB circuit board profession tolerance measurement tool, by according to customer requirement
Bound tolerance carries out thickness management and control to reach customer requirement.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement made within novel spirit and principle etc., should be included in the guarantor of the utility model
Within the scope of shield.
