Embodiment 1

[0096] A production method that can solve the problem of pre-processing film exposure connection includes:

[0097] (1) After pre-treatment and micro-etching, the plate is released, such as figure 2 shown.

[0098] (2) Temporary storage machine (such as image 3 The prior art) carries out the temporary storage of the PCB board, and cooperates with the production capacity before and after.

[0099] (3) Film laminating speed improvement: (3.1) Optimize the film laminating machine's board-in + clap action, changing the deceleration / stop / clap / transportation of the board-in mechanism to deceleration / clap 3 times, and the running time is reduced from 1.5 seconds to 0.56 seconds. (3.2) Reduce the time of film application, (three elements of film application, temperature, pressure, speed), pressure from 0.35kg / cm 2 Increased to 0.40kg / cm 2 , increasing the temperature from the traditional 110°C to 120°C (using Figure 4 The preheating machine of the automatic film laminating mac...

Embodiment 2

[0103] The present invention utilizes 100 pieces of towbar-type temporary storage machine, matched with front and rear production capacity, 5.03 pieces per minute, and can be temporarily stored for 20 minutes. The dry film requires at least 15 minutes of temporary storage for the film, which meets the technical requirements.

[0104] Film production is generally 4 blocks / minute, exposure is 4.5-5 blocks / minute, and the utilization rate of direct connection exposure capacity is only about 80%-90%, which is not conducive to maximizing equipment capacity.

[0105] The invention increases the pressure and temperature of the film, increases the speed of the film, and increases the speed of the film to 5 pieces per minute, maximizing the matching production capacity.

[0106] Such as Figure 8 As mentioned above, it is the rendering of temporary storage, film application, temporary storage, and exposure production site. The overall length is about 23 meters.

Abstract

The invention belongs to the technical field of PCB (Printed Circuit Board) manufacturing, and discloses a production method and device for solving pre-treatment film pasting exposure line connection and an application of the production method and device. The problem of direct overexposure after PCB film pasting is innovatively solved. 100 towbar type temporary storage machines are matched with the front capacity and the rear capacity, 5 towbar type temporary storage machines can be used for temporarily storing for 20 minutes per minute, the dry film is required to be temporarily stored for at least 15 minutes, and the technical requirements are met. The pressure and temperature of film pasting are improved, the film pasting speed is increased, the film pasting speed is increased to 5 pieces per minute, and the matching capacity is maximized. Compared with the prior art, connection production is achieved, and efficiency is improved. And on-line production reduces carrying and improves quality. And connection automatic production control is simple.

Description

technical field [0001] The invention belongs to the technical field of PCB (Printed Circuit Board, printed circuit board) manufacturing, and discloses a production method, a production device, a controller and an application for solving the problem of pre-processing film sticking exposure connection. Background technique [0002] At present, in the manufacture of PCB (Printed Circuit Board, printed circuit board) in the industry, the production method of pre-processing, film attachment and offline exposure is generally adopted. In the prior art, the pre-processing and film application are connected in line, and the production capacity of film application is only 4 pieces per minute. After the film is pasted, the copying machine will automatically close the plate after cooling down. The exposure machine is offline, and the offline production capacity can reach 4.5-5 blocks / minute. The speeds of the two do not match, and generally no connection is made. [0003] In order to...
