Abstract
The utility model relates to a measure tool of exposure film harmomegathus value in PCB production technology, the tool is the same just putting in two benchmark pieces that expose between the film of the exposure film shape size preceding with the deformation, there are a plurality of holes to set up the four corners at the benchmark piece on the benchmark piece for compare the deflection of exposure film harmomegathus. The utility model discloses the exposure in -process that has improved the PCB production technology has improved work efficiency to exposure film harmomegathus value measuring method, has practiced thrift the cost, has also avoided the scratch of exposure film in the transfer process simultaneously.
Description
Technical field
This utility model relates to the tool measuring exposure film (film) harmomegathus value in a kind of PCB production technology,
Belong to PCB technical field of producing.
Background technology
Exposure tool egative film (film) used in PCB produces exposure process is subject to during depositing, using
PCB processing environment (temperature 5 DEG C～40 DEG C, relative humidity 5%～85%) and course of processing impact exist bigger
Harmomegathus changes, and in order to ensure the accuracy in PCB production process, generally requires the harmomegathus value measuring exposure film.
The method measuring exposure film harmomegathus value at present is to use 2D test equipment or eight mesh testers, but this side
Method one is that cost is high, needs purchase of equipment；Two is inefficiency, needs rising of artificial manual test exposure film
Contracting value；Three is to there is hidden danger, easy scratch exposure film.Therefore, can for solution the problems referred to above offer one
The tool measuring exposure film harmomegathus value conveniently and efficiently is particularly important.
Summary of the invention
This utility model provides the tool measuring exposure film harmomegathus value in a kind of PCB production technology, need not
Quickly and easily the harmomegathus value of exposure film can be measured in the case of other equipment.
This utility model solves its technical problem and be the technical scheme is that
A kind of PCB production technology is measured the tool of exposure film harmomegathus value, it is characterised in that described tool is one
Plant the reference plate that be put in two exposure film between identical with the exposure film shape size before deformation；Further
Ground, described reference plate has 4 holes be respectively arranged at the corner of reference plate.Further, described reference plate leads to
It is often sheet glass or aluminium flake.
The beneficial effects of the utility model are:
1, cost has been saved, it is not necessary to purchase 2D test equipment or eight mesh testers just can be measured；
2, improve efficiency, it is not necessary to exposure film to be measured is taken off artificial manual measurement from exposure machine；
3, exposure film scratch in transfer process is decreased；
4, simple in construction, easily operates.
Therefore, to exposure film harmomegathus value during this utility model patent improves the exposure process of PCB production technology
The method measured, improves work efficiency, has saved cost, it also avoid exposure film in transfer process simultaneously
In scratch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use flow chart of the present utility model.
Shown in figure: 1. reference plate, 2. exposure film, 3. hole
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of PCB production technology is measured the tool of exposure film harmomegathus value, it is characterised in that institute
Stating tool is the reference plate 1 that a kind of and before deformation exposure film 2 shape size is identical, is put in two exposure films
The harmomegathus value of test exposure egative film it is used between 2；Further, reference plate 1 is drilled with the hole 3 of 4 fixed ranges.
Specifically used step of the present utility model, as in figure 2 it is shown, first taken out from cabinet by exposure film 2, is taken out
After be arranged on exposure machine (if exposure film is on exposure machine, omit this step), next by benchmark
Sheet 1 is arranged on exposure machine (being put between double-exposure egative film), the mark on exposure machine then automatic comparison exposure film
Quasi-target spot distance and the distance difference in the hole 3 of reference plate 1, calculate the harmomegathus value of exposure film finally according to difference,
Being computed qualified rear entrance PCB to produce, the defective exposure film of application the most again continues measurement until qualified.
The part not illustrated in description is prior art or common knowledge.The present embodiment is merely to illustrate this reality
With novel, rather than limiting scope of the present utility model, those skilled in the art are done for this utility model
The amendment such as equivalent replacement be all deemed to fall within this utility model right claim institute protection domain.
