Management method.
Background technology
The production procedure of printed wiring board (PCB) comprises the technical steps that：Sawing sheet-internal layer circuit-pressing-drilling-electricity
Plating-outer-layer circuit-is anti-welding-word-surface treatment-molding.
In the prior art, generally laser direct imaging (laser direct imaging, LDI) equipment is used to complete internal layer
The making of circuit and outer-layer circuit.For the pcb board of present lot 5 can be generally randomly selected after completing outer-layer circuit and making
Piece pcb board calculates the harmomegathus average value of 5 pcb boards.It is a set of anti-welding to be based on the harmomegathus average value application for the anti-welding process in road afterwards
Egative film is then based on the anti-welding making that the egative film completes batch PCB plates.
There are following defects for harmomegathus management method in the prior art：1, random sampling is there are larger sampling error, 5
The average harmomegathus value of the calculated sampling of pcb board often cannot be satisfied the anti-welding requirement of all pcb boards of the batch；2, different batches are directed to
Secondary pcb board, the calculated average harmomegathus value numerical value difference of sampling is larger, therefore, necessary for the PCB of each different batches
Using different solder prevention bottom plates, production cost is considerably increased.
Invention content
The object of the present invention is to provide a kind of anti-welding preceding harmomegathus management methods of printed wiring board comprising following steps：
Step 1: structure LDI databases, pcb board of the LDI databases for storing different item numbers, different batches
The data storage procedure of harmomegathus data, the LDI databases is as follows：Before circuit making, confirm that the drilling of the batch pcb board is risen
Contracting value, if then randomly selecting dry plate and calculating average measurement LDI harmomegathus value of the harmomegathus value as the batch pcb board, according to institute
It states and measures the LDI actual production harmomegathus values that LDI harmomegathus values specify the batch pcb board, which is completed using LDI equipment
Circuit make, finally by the item number of the batch pcb board, batch, drilling harmomegathus, measure LDI harmomegathus value and LDI actual productions and rise
Contracting value is stored in reference to harmomegathus data record to the LDI databases as one；
Step 2: before being made into row line to the pcb board of present lot, the LDI is inquired according to item number and lot number
Database is to specify the harmomegathus data of the pcb board of present lot, to ensure same item number, with the drilling of a batch of pcb board
Harmomegathus is consistent with LDI actual production harmomegathus values.
In a specific embodiment, in the step 1,10 pcb boards is randomly selected and calculate 10 pcb boards
Measurement LDI harmomegathus value of the average harmomegathus value as the batch pcb board.
The technique effect of the anti-welding preceding harmomegathus management method of printed wiring board provided by the invention is as follows：
1, the harmomegathus ratio section for reducing the same production item number, reduces pcb board scale error, it is accurate to improve client's piece uploading
Rate；
2, it reduces anti-welding production cost and improves anti-welding production efficiency；
3, the cost of processing procedure after effectively being controlled with management circuit production harmomegathus ratio.
Specific implementation mode
To illustrate the thought and purpose of the present invention, the present invention is described further With reference to embodiment.
First, " one embodiment " or " embodiment " referred to herein refers to that may be included at least one realization side of the present invention
A particular feature, structure, or characteristic in formula." in one embodiment " that different places occur in the present specification not refers both to
The same embodiment, nor the individual or selective embodiment mutually exclusive with other embodiment.
The anti-welding preceding harmomegathus management method of printed wiring board provided by the invention comprising following steps：
Step 1: structure LDI databases, pcb board of the LDI databases for storing different item numbers, different lot numbers
Harmomegathus data.Every harmomegathus data include item number, lot number, drilling harmomegathus value, measure LDI harmomegathus value and LDI actual productions
Five fields such as harmomegathus value.
The data storage procedure of the LDI databases is as follows：Before circuit making, confirm that the drilling of the batch pcb board is risen
Contracting value, if then randomly selecting dry plate and calculating average LDI harmomegathus value and the measurement LDI harmomegathus values as batch PCB plates,
The LDI actual production harmomegathus values that the batch pcb board is specified according to the measurement LDI harmomegathus values, the batch is completed using LDI equipment
The circuit of pcb board makes, finally that the item number of batch PCB plates, lot number, drilling harmomegathus value, measurement LDI harmomegathus value and LDI is real
Border produces harmomegathus value and is stored in the LDI databases with reference to harmomegathus data record as one.
Step 2: before being made into row line to the pcb board of present lot, the brill of the PCB plates of present lot is first determined
Then hole harmomegathus value inquires the LDI databases to determine the harmomegathus data of the pcb board of present lot according to item number and lot number,
To ensure same item number, it is consistent with the LDI actual production harmomegathus values of a batch of pcb board.Specifically：
If the drilling harmomegathus value of the pcb board of present lot and the corresponding history harmomegathus data in the LDI databases
