The blind punching die is utilized for punching FR-4 at the position of a bending area, a blind breakage is punched without damaging the circuit, the bending area can not be impacted by copper plating medical liquid,and the blind punching die has improved finished product ratio, simple method, easy realization and stable quality.
Description
Technical field
The utility model relates to the process equipment of rigid-flex combined board, particularly relates to special-purpose blind punch die tool.
Technical background
Rigid-flex combined board is as a kind of special electronic interconnection technology, can reduce electronic product package size, weight, avoid Miswire, realize the three-dimensional assembling under the different assembled conditions, and have light, thin, short, little, structure flexible characteristic, be widely used in computer, aviation electronics, Military Electronic Equipment, mobile phone, DV, Communication Equipment, the analytical instrument.The U.S. is very ripe with rigid-flex combined board on military and space science, and the number of plies mostly is 6,8,10 layers.Korea S PCB (printed circuit board) manufacturer is in the technical maturation the most of rigid-flex combined board at present, and other regional manufacturers are stepping up the research and development to rigid-flex combined board technology now.Rigid-flex combined board can be used to reduce field, the especially consumer field of encapsulation from now on.
The existing rigid layer flow process of rigid-flex combined board is: blanking → boring → gong type → fit with flexible layers → hole → PTH (electroless copper plating)/copper facing → circuit → anti-welding, at this flow process, rigid-flex combined board has one or more flexion zones, one or more grooves are promptly arranged, when adopting traditional dry film imaging manufacture craft, because of dry film is difficult to seal groove, when graphic plating, can cause and scrap in flexion zones electricity plated with copper, and coverlay can not stand the attack of heavy copper liquid medicine, therefore, must be at the preceding groove of sealing of imaging (or graphic plating).
Existing general technology is: before graphic plating with red gummed paper sealing groove; the protection flexion zones when electroplating, do not touch electroplate liquid medicine and can plated with copper and coverlay can not be subjected to the attack of heavy copper alkaline medicinal liquid; but this kind technology can not guarantee that the width of red gummed paper is the same with the width of deflection; if the different then red gummed paper of width is bad to its sealing effectiveness; thereby when graphic plating, just have liquid medicine and be penetrated into flexion zones, and cause wiring board to be scrapped.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of blind punch die tool that is exclusively used in rigid-flex combined board is provided, make rigid-flex combined board before heavy copper, need not paste red glue like this, blindly wash out but after circuit, adopt, and do not damage its circuit towards the FR-4 of technology with deflection place.
For solving the problems of the technologies described above, the utility model provides a kind of blind punch die tool of rigid-flex combined board special use, it is characterized in that, comprises cope match-plate pattern and lower bolster; On the die joint of lower bolster, be provided with the reference column that is used for fixing the relative position of rigid-flex combined board on mould, also be provided with the die-cut cutting edge of protrusion, both sides on this die joint also are provided with the limited block of protrusion symmetrically, the height of described limited block is higher than the height of described die-cut cutting edge, and the difference in height of the two equals gross thickness after the rigid-flex combined board etching and deducts single face and need the blind degree of depth of dashing.
The angle of described die-cut cutting edge is 10～30 degree.
The die joint of described cope match-plate pattern is the plane, and the die joint flatness of described cope match-plate pattern is in 0.01mm.
Flatness on the described die-cut cutting edge is in 0.005mm.
Gross thickness tolerance≤0.03mm that described upper and lower template is closed up.
Described limited block is a strip of being located at the die joint both sides of the edge.
Described reference column is four, and arrangement is square.
Be provided with elastic plastic between described cope match-plate pattern and the punch press or between lower bolster and the punch press.
Because blind punch die tool of the present utility model has been arranged, the blind of rigid-flex combined board towards technological process is: rigid material blanking → boring → fit with flexible layers → rigid-flex combined board boring → PTH (electroless copper plating)/copper facing → circuit → blind dashing → anti-welding.According to this technology, finish circuit after, the FR-4 with the flexion zones place washes out again, because the limited block height greater than the height of die-cut cutting edge, forms the restriction of the cutting-in degree that liquidates, make and go out blind breaking, do not damage its circuit, and its flexion zones can not be subjected to the attack of heavy copper liquid medicine yet, improve yield rate.The die-cut degree of depth determines that by the thickness of the FR-4 of rigid-flex combined board like this, method is simple, realizes easily, and steady quality.

The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the upper and lower mould exploded perspective view of the blind punch die tool of rigid-flex combined board special use of the present utility model.
Fig. 2 is the side view cutaway drawing of the blind punch die tool of rigid-flex combined board special use of the present utility model.

Concrete embodiment
Be the blind punch die tool of rigid-flex combined board special use of the present utility model as Figure 1-3, form, the gross thickness tolerance need≤0.03mm that upper and lower template is closed up by cope match-plate pattern 10 and lower bolster 20.The die joint of cope match-plate pattern 10 is the plane, and this cope match-plate pattern principal security flatness requires in 0.01mm; On the die joint 21 of lower bolster 20, be provided with four reference columns 30 that are square and arrange that are used for fixing the relative position of rigid-flex combined board on mould, also be provided with the die-cut cutting edge 22 of protrusion, die-cut cutting edge guarantees die-cut width, require cutting edge smooth, sharp, flatness is in 0.005mm.Shown in Fig. 2 and 3, the angle b of the blade of die-cut cutting edge 22 is between 10 °～30 °.Both sides of the edge on the die joint 21 of described lower bolster 20 also are provided with the strip limited block 23 of protrusion symmetrically, the height of described limited block is higher than the height of described die-cut cutting edge, limited block guarantees the die-cut degree of depth, and the two difference in height of the top of the upper surface of limited block 23 231 and die-cut cutting edge 22 221 equals gross thickness after the rigid-flex combined board etching and deducts single face and need the blind degree of depth of dashing.The die-cut degree of depth also will be considered the angle b of blade, and when knife height was higher, then angle b just needed design bigger, and when knife height was low, it is less that then angle b just needs design.The two difference in height of the upper surface 231 of limited block 23 and the top of die-cut cutting edge 22 221 is the die-cut degree of depth, needs to be decided by the thickness of the FR-4 of rigid-flex combined board.
Consider the rigidity location dimension of mould; to punch press flexible requirement must be arranged; can control by elastic plastic; elastic plastic is placed between patrix or counterdie and the punch press; its objective is that when the mode transfer height surpassed spacing size, then elastic plastic was under pressure and shrinks; thereby to punch press a power of rebounding is arranged, guarantee that punch press is not stuck.
