Abstract

The utility model discloses a PCB blue gum screen printing device comprising a screen printing stand, wherein a PCB is arranged on a screen printing table board of the screen printing stand and is provided with a plurality of plug holes, a blue gum screen printing meshed plate is fixed on the PCB, and meshes corresponding to the plug holes on the PCB are formed on the blue gum screen printing meshed plate. The utility model adopts the blue gum screen printing meshed plate to replace the original silk screen, and has the meshes corresponding to the plug holes on the PCB formed on the blue gum screen printing meshed plate, so that during the screen printing process, blue gum can pass the meshes on the blue gum screen printing meshed plate uniformly into the plug holes on the PCB. Therefore, the blue gum in the plug holes on the PCB is more uniform and is prevented from generating bubbles, and the quality of the products is improved.

Description

The blue collodion silk printing device of a kind of pcb board

Technical field

The utility model relates to the printed wiring plate technique, particularly a kind of device that is used for pcb board is carried out blue collodion silk seal.

Background technology

Pcb board need be with ink printing to the pcb board in the corresponding through hole when carrying out silk-screen, and traditional method is to adopt blue collodion silk reticulated printing usually, and pcb board is placed on the silk-screen table top, covers blue collodion silk net then on pcb board, prints.But because blue collodion silk net occurs easily in use that the mesh screen plughole stopple is not full, problem such as cavity in the hole, thereby cause in the pcb board through hole producing quality problem such as blue glue bubble and blue glue is in uneven thickness, the repair rate of the blue offset plate of serigraphy that is therefore adopted in the blue collodion silk reticulated printing is very high.

Summary of the invention

For addressing the above problem, the purpose of this utility model is to provide a kind of pcb board blue collodion silk printing device, causes the problem that pcb board through hole medium blue glue is in uneven thickness and repair rate is high to solve the blue offset plate of traditional silk-screened.

For achieving the above object, the utility model is mainly by the following technical solutions:

The blue collodion silk printing device of a kind of pcb board, comprise silk-screen platform (1), the silk-screen table top (101) of described silk-screen platform (1) is provided with pcb board (2), this pcb board is distributed with a plurality of consents on (2), and be fixed with a blue collodion silk seal web plate (3) on the pcb board (2), described blue collodion silk seal web plate (3) is provided with the mesh (301) of pcb board (2) consent correspondence.

Described blue collodion silk seal web plate (3) is an aluminium sheet.

Described blue collodion silk seal web plate (3) both sides also are provided with sealed adhesive paper (302).

The utility model adopts blue collodion silk seal web plate to replace original silk screen, and blue collodion silk seal web plate offer with pcb board on the pairing mesh of consent, in the silk-screen process, can make blue glue uniformly by the mesh on the blue collodion silk seal web plate, enter into consent on the pcb board, make pcb board consent medium blue glue more even, avoided consent medium blue glue generation bubble on the pcb board, improved the quality of product.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Identifier declaration among the figure: silk-screen platform 1, silk-screen table top 101, pcb board 2, blue collodion silk seal web plate (3, mesh 301, sealed adhesive paper 302.

The specific embodiment

For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.

See also shown in Figure 1ly, Fig. 1 is a structural representation of the present utility model.The utility model provides the blue collodion silk printing device of a kind of pcb board, is mainly used at PCB in the silk-screen process, prevent to occur blue glue bubble in the pcb board consent, and consent medium blue glue problem in uneven thickness.

Wherein this device mainly comprises silk-screen platform 1, the silk-screen table top 101 of described silk-screen platform 1 is provided with pcb board 2, be distributed with a plurality of consents on this pcb board 2, and be fixed with a blue collodion silk seal web plate 3 on the pcb board 2, described blue collodion silk seal web plate 3 is provided with the mesh 301 of pcb board 2 consent correspondences.

Above-mentioned blue collodion silk seal web plate 3 is an aluminium sheet, is distributed with a plurality of mesh 301 on it, and both sides are then fixing by sealed adhesive paper 302.The manufacturing process of this indigo plant collodion silk seal web plate 3 is as follows: at first look for a silk screen to measure web plate, hole-drilled aluminium flake front is affixed on the printing surface of this silk screen, the good corresponding position of contrast, cut into screen frame aluminium flake generally big or small, on aluminium flake and silk screen, apply Instant cement then, so that paste aluminium flake and silk screen tight, after parking 2 hours, again silk screen is sliced off with blade, and seal with sealed adhesive paper on the both sides of silk screen, completing of blue collodion silk seal web plate aluminium flake net, and then keep under 45-55 ℃ the condition, adding roasting 20min on baking oven can normally use.

According to traditional processing mode, the repair rate of the blue offset plate of common serigraphy adopts blue collodion silk in this device to print repair rate that web plate aluminium flake net prints in 1%, thereby promotes production efficiency greatly about 50%, shorten online Production Time, guarantee to produce the friendship phase.

More than the blue collodion silk printing device of a kind of pcb board provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
