Abstract
The utility model discloses an improved tool for measuring the thickness of a PCB. The tool comprises a vernier caliper, wherein a ruler is additionally mounted on a measuring jaw of the vernier caliper, extending the length of the measuring jaw. When the thickness of the PCB is to be measured, the measuring jaw is firstly used to measure the periphery of the PCB, and the ruler additionally mounted on the measuring jaw is used to measure the center of the PCB. The tool for measuring the thickness of the PCB solves the difficulties in measuring large PCBs with a simple structure and a low cost, and has the advantages of convenience, quickness, and low price.
Description
Technical field
The utility model relates to a kind of measuring appliance, especially a kind of utensil of survey pcb board thickness of improvement.
Background technology
In the process that pcb board is produced, in order to guarantee the even thickness of pcb board, generally use the size that survey instrument is measured its length, thickness.Because the size of pcb board is as required and tailor-make, when producing the pcb board of some large-sizes, there is not suitable instrument to measure, some fairly large manufacturers can measure with special instrument, the price of these instruments is more expensive, and medium and small sized enterprises are difficult to bear these costs.
The utility model content
The purpose of this utility model is to provide a kind of utensil of survey pcb board thickness of improvement, reaches the purpose of measuring large scale pcb board thickness with simple and practical instrument.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of utensil of survey pcb board thickness of improvement comprises: vernier caliper, install ruler additional on the measuring claw of described vernier caliper, and be equivalent to measuring claw elongated.
The inside edge of measuring claw flushes with the inside edge of ruler.
When measuring pcb board thickness, by around the measuring claw measurement pcb board, measure again the center of pcb board by the ruler that installs additional on the measuring claw first.
The very simple structure of the utility model utilization, low-down cost have solved the problem that larger pcb board is difficult to measure easily, and convenient, fast, cheap.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, measuring claw; 2, ruler.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1: a kind of utensil of survey pcb board thickness of improvement comprises: vernier caliper, install ruler 2 additional on the measuring claw 1 of described vernier caliper, and be equivalent to measuring claw 1 elongated.
When measuring pcb board thickness, by around the measuring claw 1 measurement pcb board, measure again the center of pcb boards by the ruler 2 that installs additional on the measuring claw 1 first.
The utility model is not limited to above-mentioned embodiment; the according to the above description announcement of book and guidance; the utility model those skilled in the art also can carry out suitable change and modification to above-mentioned embodiment, and its change also should fall into the protection domain of claim of the present utility model.In addition, although used some specific terms in this instructions, these terms do not consist of any restriction to the utility model just for convenience of description.
Claims (1)
1. the utensil of the survey pcb board thickness of an improvement, comprising: vernier caliper is characterized in that: install ruler additional on the measuring claw of described vernier caliper.
