The processor judges whether the copper clad laminate data can be subjected to self-pressing and needs to detect and judge the impedance tolerance, the number of layers of the self-pressing plate and the copper clad laminate material.

The logic for judging the impedance tolerance test is as follows, and judges whether the impedance tolerance requirement is smaller than that of a conventional product, wherein the conventional tolerance is as follows: if the impedance tolerance of 50ohm is less than +/-10%, the output result is that the self-pressing material can not be used, and a purchase processing instruction is output.

And the self-pressing order information comprises the material shortage plate information and the prepreg cutting information. The short material plate information main comprises the thickness of the short material plate, the structure of the product, the thickness of the copper foil and the type of the copper foil. The prepreg cutting information comprises the gel content, the cutting size, the warp and weft directions, and the type, the thickness and the size of the copper foil.

The detection unit detects whether the copper-clad plate meets the requirements, and the detection unit needs to detect the lamination information of the self-pressing plate, wherein the lamination information comprises the structure of the copper foil, the thickness of the copper foil, the type and the number of the copper foil.

In addition, the processor also needs to perform function check and appearance detection on the formed target copper-clad plate, if the product does not conform to the product which is checked and accepted according to the GJB-362 requirement, the processor outputs the result that the product cannot be made of the self-pressing material, and outputs a purchasing processing instruction.

The processor judges whether the self-pressing plate needs self-pressing partially, if so, the processor outputs a result that the self-pressing plate cannot be manufactured by self-pressing materials, and outputs a purchasing processing instruction.

And the processor judges the number of the orders generated by the self-pressing plate, presets an N value, judges whether the number of the orders is greater than N, and if so, outputs a result that the self-pressing material cannot be used for manufacturing and outputs a purchasing processing instruction.

And the processor judges the number of layers of the self-pressing plate and the conductor distance, if the number of layers of the self-pressing plate is more than or equal to 12 and the distance between the hole and the conductor is less than or equal to 6mil, if the judgment result is yes, the processor outputs the result that the self-pressing material cannot be used for manufacturing, and outputs a purchase processing instruction.

If the judgment result is yes, the processor outputs the result that the self-pressure material cannot be manufactured and outputs a purchase processing instruction.

And traversing the judgment process by the processor, and generating a self-pressure instruction and issuing self-pressure order information only when all judgment results are negative.

The selection of the thickness of the copper foil needs to be selected according to the defective specification, and the type of the self-pressing copper foil needs to be judged to be HTE, RTF or HVLP according to the specification information of the defective plate.

In addition, when judging whether the self-pressing is available, the processor also needs to judge according to the thickness, copper thickness and the configuration structure of the lack material plate by combining a self-pressing specification table;

TABLE 1

And when the judgment result is that the self-pressing is available and the prepregs and the copper foils with the corresponding specifications are stored, generating cutting information of the prepregs and the copper foils.

The specific pattern of the cutting information is shown in table 2.

TABLE 2

In addition, the copper-clad plate needs to be subjected to material control, and if the copper-clad plate is re-ordered and placed, the cutting unit firstly judges whether the plate is stored and preferentially uses the plate. When the inventory is insufficient, the cutting unit pre-calculates the number of the copper-clad plates capable of being produced by self-pressing. The cutting unit judges whether the self-pressure exists according to the preset delivery date, and if the self-pressure does not exist, a purchasing processing instruction is carried out; and if so, cutting according to the cutting information to manufacture the plate.

And the drawing design unit is used for generating a drawing of the copper-clad plate laminated structure according to the pressure data, and the processor issues the drawing design requirement to the drawing design unit. ,

when the laminated structure drawing is designed, a system generates a computer-aided manufacturing process, wherein the manufacturing process comprises the following steps: cutting material [ open prepreg → open copper foil ] → pressing copper clad laminate [ prearranged → arrange board → press ] → finished product warehouse [ warehouse in ]

The flows of prepreg opening, copper foil opening and copper-clad plate pressing are only limited to copper-clad plate selection, and other orders cannot be selected.

Filling copper-clad plate cutting process information: the system needs to indicate the type, the glue content, the cutting size, the warp and weft directions of the self-pressing plate, the type, the thickness, the size and other information of the copper foil.

To ensure that the thickness of the copper clad laminate meets the requirement, the dimensions of the self-pressing board and the copper foil are calculated according to the following rule, and the system calculates the required dimensions of the self-pressing board, for example, as shown in Table 3

TABLE 3

Book matching structure	Prepreg oversized compared to the splice	Copper foil increases size than whole makeup
			1-3 prepregs	The length and the short side are respectively increased by 0.5inch	Each long and short side is increased by 2inch
4 pieces of or more than half-solidChemical sheet	Each long and short side is increased by 2inch	Each long and short side is enlarged by 5inch

Specific examples are as follows: the required dimension of the self-pressing plate is 16 x 18inch, the self-pressing plate (0.15mm thickness) of the structure 2 x 1080 is adopted, the indicator controls the semi-cured sheet plate to be cut, the target dimension information is 16.5 x 18.5inch, and the copper foil dimension is 18 x 20 inch.

When the self-pressing plate in the same batch has the structure of the original single prepreg and the original configuration of the plurality of prepregs, the indication information is filled according to the maximum increasing size.

For example: not only needs to press the prepreg with the thickness of 0.1mm and the thickness of 3313X 1 to prepare the structure, but also needs to press the prepreg with the thickness of 0.8mm and the thickness of 7628X 4 to prepare the structure, so that the prepreg is increased by 2 inches on one side when cutting, and the copper foil is increased by 5 inches on one side compared with the prepreg.

3) during cutting, the copper foil type needs to be consistent with that of the order work card, and the copper foil type cannot be replaced with the order work card (HTE, RTF and HVLP copper foil).

Wherein the requirements for autogenous platen production and inspection include: 1) whether the lamination procedure in the copper-clad plate manufacturing process accords with the preset lamination information: the structure is matched (note: the sequence is not disordered), the copper thickness, the copper foil types and the number are pre-arranged, and a special self-pressing program indicated by a system is adopted for pressing, wherein the pressing program needs to calculate the pressure according to the actual size of the prepreg and the size of a press (a large press or a small press). 2) And after lamination is finished, the self-pressed plate is self-inspected by a lamination process according to lamination specifications, and the self-pressed plate comprises plate surface quality and plate thickness.

After the self-inspection is passed, the self-pressing plate is transferred to the next process, and meanwhile, the final inspection process is used for inspecting the plate thickness, the copper thickness and the plate surface quality of the copper-clad plate (such as scratches, pits, adhesive residues and the like);
