Further, Fig. 8 and Fig. 9, the thickness of third matching board 180 and the thickness h of hierarchic structure 112 are please referred to₄Difference Absolute value be less than 0.1mm.It is rationally controlled between the thickness of third matching board 180 and the thickness of hierarchic structure 112 in this way, passing through Difference, so that third matching board 180 preferably fills up the difference in height between internal layer rigid plate 1113 and hierarchic structure 112.Specifically exist In the present embodiment, when hierarchic structure 112 stretches out the second perforation 181, between hierarchic structure 112 and the hole wall of the second perforation 181 Gap width D₂For 0.5mm~1.0mm.It follows that when the gap mistake between hierarchic structure 112 and the hole wall of the second perforation 181 Hour, the burr in the second perforation 181 is stuck between hierarchic structure 112 and the second perforation 181, and third matching board 180 is caused to be difficult to Smoothly covers in hierarchic structure 112 or be detached from from hierarchic structure 112；Meanwhile it being also easy to scratch the table of hierarchic structure 112 Face causes the use function of hierarchic structure 112 impaired；Gap mistake between hierarchic structure 112 and the hole wall of the second perforation 181 When big, cause to be easy strike-through between the hole wall and hierarchic structure 112 of the second perforation 181, it is rigid-flexible to seriously affect winged tail hierarchic structure The appearance of board 100.Therefore, the present embodiment is by rationally controlling between hierarchic structure 112 and the hole wall of the second perforation 181 Gap, so that third matching board 180 is more smoothly inserted in hierarchic structure 112；Meanwhile it being also beneficial to guarantee that winged tail hierarchic structure is rigid The overall appearance of flex combined board 100.

In one embodiment, referring to FIG. 7, the step of providing rigid-flexible combination daughter board 111S11, comprising: respectively to outer layer Rigid plate 1111, internal layer rigid plate 1113, flex plate 1112 carry out route processing；Route processing after, to outer layer rigid plate 1111, Flex plate 1112 and internal layer rigid plate 1113 are successively pressed together.In this way, in this way, obtaining the rigid-flexible of stable structure In conjunction with daughter board 111.Since just line will have been carried out in internal layer rigid plate 1113 in rigid-flexible 111 preparation process of combination daughter board Road, solder mask and surface treatment, therefore, two rigid-flexible combination daughter boards 111 during the pressing process, are not necessarily to internal layer rigid plate 1113 It is processed, effectively avoids internal layer rigid plate 1113 that from can not putting route, solder mask and surface work to good use because of hierarchic structure 112 Skill, in this way, greatly optimizing the preparation process of winged tail hierarchic structure rigid-flex combined board 100.It should be noted that the present embodiment Outer layer rigid plate 1111 is interpreted as one or more rigid core plate and presses；Equally, internal layer rigid plate 1113 should also manage Solution presses for one or more rigid core plate；Wherein, core plate is made of substrate and copper foil.Outside due to the present embodiment Layer rigid plate 1111, internal layer rigid plate 1113 and flex plate 1112 are existing structure, and therefore, specific structure repeats no more.

In one embodiment, it referring to FIG. 10, pressing the rigid-flexible daughter board 110 of two ladders after cooperation, is formed rigid Before scratching in conjunction with the step of motherboard S40, further includes: paste protective layer 190 to the surface of hierarchic structure 112.In this way, passing through protective layer 190, protect 112 surface of hierarchic structure not to be subject to crushing.Specifically in the present embodiment, protective layer 190 is protective glue band, main to protect Solder mask in hierarchic structure 112.

In one embodiment, Fig. 6 and Fig. 7 are please referred to, the step of subsequent processing S50 is carried out to rigid-flexible combination motherboard Suddenly, comprising:

S51, drilled to rigid-flexible combination motherboard, be electroplated and route processing；

S52, solder mask printing is carried out to the surface of outer layer rigid plate 1111, and by the outer layer rigid plate in flexible region 130 1111 carry out taking off lid processing；

S53, the solder mask of outer layer rigid plate 1111 is solidified.In this way, in this way, obtaining flying for stable structure Tail hierarchic structure rigid-flex combined board 100.

In one embodiment, Fig. 1, Fig. 7 and Figure 10, a kind of winged tail using in one embodiment of any of the above are please referred to The winged tail hierarchic structure rigid-flex combined board 100 of 100 production method of hierarchic structure rigid-flex combined board production.

Above-mentioned winged tail hierarchic structure rigid-flex combined board 100 is made using above winged tail hierarchic structure rigid-flex combined board 100 Make method, first the offer rigid-flexible daughter board 110 of two ladders；Two matching board structures 170 are provided again, the cooperation of matching board structure 170 is existed In internal layer rigid plate 1113.Since matching board structure 170 is equipped with the first perforation 1721, including the cooperation of matching board structure 170 When in layer rigid plate 1113, hierarchic structure 112 is stretched out from the first perforation 1721, in this way, effectively the rigid-flexible daughter board 110 of ladder is avoided to exist In bonding processes, matching board structure 170 causes to interfere to hierarchic structure 112.Again since matching board structure 170 is backwards to internal layer rigid plate 1113 one side is flushed or is substantially flush with 112 surface of hierarchic structure, therefore, has filled up ladder by matching board structure 170 Difference in height between structure 112 and internal layer rigid plate 1113 is pressurized uniformly so that the rigid-flexible daughter board 110 of ladder is during the pressing process, To effectively solve decompression lamination problem occur when the rigid-flexible daughter board 110 of ladder presses, so that flying tail hierarchic structure rigid-flex combined board 100 yield rate is protected.
