Embodiment 1

[0039] see figure 1 , the present embodiment provides a method for controlling anti-mixing batches in the PCB production process, comprising the following steps:

[0040] Step S101, assigning a unique ID code to each chip board in advance.

[0041] The ID code is also called 8421 code, which is allocated according to the principle of uniqueness. In order to achieve accurate traceability of quality, its information includes: model, batch number and core board number.

[0042] Step S102, spraying its corresponding ID code on each core board with an inkjet printer.

[0043] For the convenience of reading, the spraying position is preferably set to a fixed area of ​​the board edge of the core board.

[0044] Step S103 , according to the ID code, the several chip boards are screened according to the model and batch number.

[0045] The screening process includes:

[0046] Set the model and batch number for this screening;

[0047] Put each core board to be screened in turn;

...

Embodiment 2

[0054] In Embodiment 1, the ID code is set by spraying. However, in the subsequent production process, the information formed by spraying is easily covered or affected, making it unclear and unable to be read accurately and quickly. Therefore, the second embodiment optimizes the solution of the first embodiment.

[0055] see figure 2 , the present embodiment provides a method for controlling anti-mixing batches in the PCB production process, comprising the following steps:

[0056] Step S201, assigning a unique ID code to each chip board in advance.

[0057] The ID code is also called 8421 code, which is allocated according to the principle of uniqueness. In order to achieve accurate traceability of quality, its information includes: model, batch number and core board number.

[0058] Step S202 , according to the pre-assigned ID code for each core board, generate a unique through hole arrangement; according to the through hole arrangement, drill through holes at the corres...

Embodiment 3

[0071] This embodiment provides a control system for anti-mixing batches in the PCB production process, including: an ID code setting device and a core board screening device.

[0072] The ID code setting device is used to pre-allocate a unique ID code for each core board, and set its corresponding ID code on each core board. The information content of the ID code includes: model, batch number and core board serial number;

[0073] The core board screening device is used to screen several core boards according to batches according to the ID code.

[0074] Wherein, the ID code setting device further includes: a hole row generation unit, used to generate a unique through hole arrangement according to the ID code pre-assigned for the current core board; Permutation, drill through holes at the corresponding position of the current core board.

[0075] Wherein, the core board screening device further includes: a setting unit for setting the model and batch number of each screenin...

Abstract

The invention discloses a control method and system against batch mix-up in a PCB production process. The method comprises that each core plate is distributed with a unique ID code and provided with the corresponding ID code, and information of the ID code includes the model, the batch number and the number of the core plate; and the core plates are screened according to the models and batch numbers of the ID codes. Thus, the core plates of different batches can be screened rapidly and accurately according to the ID codes, the phenomenon of batch mix-up is avoided, quality-related accidents are avoided, and the production quality and efficiency are improved; and the ID code arranged in the edge of the core plate in a hole row form can be read conveniently and rapidly, is effectively prevented from adverse influence and is durable.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a method and system for controlling anti-mixing batches in the PCB production process. Background technique [0002] PCB, also known as printed circuit board, printed circuit board, or printed board for short, is based on an insulating board, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component holes, fastening holes, etc.) , metallized holes, etc.), and realize the interconnection between electronic components. Since such boards are made using electronic printing, they are called "printed" circuit boards. [0003] In the PCB manufacturing process, multiple core boards with graphic circuits are fused and pressed together with two outer copper foils, and then the outer copper foils are drilled, plated, and etched to form a multilayer PCB. For a long time, in the PCB industry, it is easy to mix batches when making multi-l...
