Abstract
The utility model discloses an external manual exposure machine, which comprises an exposure frame, wherein the exposure frame includes toughened glass and a MYLAY member adhered to the toughened glass. The external manual exposure machine is characterized in that a bare copper substrate is disposed below the MYLAY membrane. The bare copper substrate below the MYLAY membrane of the exposure frame can greatly obviate the occurrence of poor air suction during the work process of the external manual exposure machine, thereby saving the labor power and time.
Description
Technical field
The utility model relates to a kind of manual exposure machine, belongs to the printed circuit board (PCB) processing technique field.
Background technology
Outer manual exposure machine is an exposure sources commonly used in the print circuit plates making process, usually the exposure framework of manual exposure machine comprises a tempered glass, on tempered glass, paste one deck MYLAR film, when outer manual exposure machine is made, need manually catch up with gas, waste of manpower, time, promptly cause air-breathing bad easily.For solving this technical matters, 200920129214.3 the utility model discloses a kind of inner layer of printed-circuit board manual exposure machine, this inner layer of printed-circuit board manual exposure machine comprises the exposure framework, the glass table top, the metal handle, the hydraulic pressure support bar, the venting button, gas port, tracheae, three-way connection, O-ring seal is characterized in that: the exposure framework is made up of the tempered glass that vacuumizes between two, and metal handle (C) is installed on the upper glass table top, venting button (E) is installed on the upper glass table top, and O-ring seal (K) is installed at the upper glass edge.The utility model adds glass by the framework that will expose by concavo-convex wheat membrane and forms the tempered glass that transform as by vacuumizing between two and form, can guarantee good edges of boards vacuum tightness when producing the large-size glass plate period of the day from 11 p.m. to 1 a.m, improved the production efficiency of exposure machine, also improve simultaneously glass serviceable life, and promoted the production quality.But the tempered glass processing cost that vacuumizes between two is higher, and thickness increases.
The utility model content
Technical problem to be solved in the utility model provides a kind of outer manual exposure machine, and it is air-breathing bad to improve dry film, saves manpower, time, reduces air-breathing bad scrapping of causing.
For solving the problems of the technologies described above, the utility model provides a kind of outer manual exposure machine, comprises the exposure framework, and the exposure framework comprises tempered glass and the MYLAR film that pastes on it, it is characterized in that: be arranged with the naked copper substrate at the MYLAR film.
The beneficial effect that the utility model reached:
Outer manual exposure machine of the present utility model is provided with one deck naked copper substrate below the MYLAR film of exposure framework, can reduce air-breathing bad phenomenon appearance in the outer manual exposure machine course of work greatly, saves manpower, time.
Description of drawings
Fig. 1 is the exposure frame shelf structure synoptic diagram of outer manual exposure machine of the present utility model.
Embodiment
Outer manual exposure machine of the present utility model comprises exposure framework 1, and exposure framework 1 comprises tempered glass and the MYLAR film 2 that pastes on it, is arranged with naked copper substrate 3 at MYLAR film 2.A kind of mylar of MYLAR film is Maila paper or para tape again.Air-breathing bad phenomenon appearance in the outer manual exposure machine course of work be can reduce greatly after increasing the naked copper substrate, manpower, time saved.
Below only with most preferred embodiment the utility model is described further, so it is not to qualification of the present utility model, and protection domain of the present utility model is as the criterion with the content that is illustrated in claim.
Claims (1)
1. an outer manual exposure machine comprises the exposure framework, and the exposure framework comprises tempered glass and the MYLAR film that pastes on it, it is characterized in that: be arranged with the naked copper substrate at the MYLAR film.
