Description
Technical field
The present invention relates to board production technical field more particularly to a kind of forming methods of cell board.
Background technology
In the production of PCB, internal layer circuit making, pressing, outer-layer circuit making, resistance are carried out typically in a manner of jigsaw
To produce the required half-finished product plate with several cell boards, (half-finished product plate is several to the processes such as layer making, surface treatment
Cell board is composed and laid out jigsaw together, and other regions on jigsaw in addition to cell board are known as technique edges；Unit on usual jigsaw
Plate is arranged with array, each unit plate Component units plate array；For the cell board positioned at unit plate array periphery, it is located at unit
The cell board edges of boards in plate array sideline are known as outside edges of boards, and other cell board edges of boards are then known as inside edges of boards), then pass through again
Each unit plate in jigsaw is respectively cut out by molding procedure, the cell board being cut into i.e. finished product PCB.In the prior art,
When carrying out molding procedure, the cell board in the direct milling jigsaw of nearby principle is typically pressed, but when four of cell board in jigsaw
When the cell board edges of boards in a direction have multi-line section edges of boards, especially in milling thin-plate element plate, the technique edges between cell board are narrow
Long, the cell board of rear milling can be because of each point and technique on cell board edges of boards on straight-line segment identical with the cell board edges of boards direction
The distance between side plate side is inconsistent, so as to cause cell board edges of boards unbalance stress during milling, therefore the cell board edges of boards
Concavo-convex position can be formed, dimensional discrepancy is caused.As shown in Figure 1, jigsaw includes cell board A, B, C, D four identical pieces of, unit
There are two adjacent single line section edges of boards and two adjacent multi-line section edges of boards, single line section edges of boards in the cell board edges of boards of the four direction of plate
Refer to that the edges of boards of the cell board direction are made of a straight-line segment, such as the a1 in Fig. 1, multi-line section edges of boards refer to the cell board party
To edges of boards be made of more straight-line segments, such as the a2 in Fig. 1；When carrying out milling to the jigsaw, if first milling cell board A, milling
Jigsaw after cut unit plate A is as shown in Fig. 2, the single line section edges of boards b1 of cell board B is inconsistent at a distance from technique edges edges of boards, milling
When cell board B, it is easy to generate concavo-convex position, the position as shown in b3 in Fig. 2 at the single line section edges of boards；For cell board C also one
Sample will produce concavo-convex position, the position as shown in c3 in Fig. 2 at the single line section edges of boards c1 of cell board C.
If come the problem of reducing unbalance stress by way of increasing the size of technique edges when design, the appearance and size of jigsaw
It can be affected, this mode is undesirable for quality and cost.
Invention content
There is concavo-convex position and lead to ruler in the cell board edges of boards that the present invention is easy to cause cell board for existing forming method
Very little deviation, the problem of influencing quality of finished, provide a kind of avoidable cell board edges of boards and the unit sheet metal forming side of concavo-convex position occur
Method.
To achieve the above object, the present invention uses following technical scheme.
A kind of forming method of cell board is arranged to make up jigsaw, in jigsaw upper edge by several cell boards with array
The cell board edges of boards of cell board are cut, and so that each unit plate on jigsaw is detached independence, in the list of jigsaw upper edge cell board
It is further comprising the steps of before first plate edges of boards are cut：It is cut, is formed straight on technique edges between two adjacent cell boards
Line notch, the linear incision are parallel with the row or column being made of cell board on jigsaw.
Further, in the cell board edges of boards of the four direction of the cell board at least one direction cell board edges of boards
For multi-line section edges of boards.
Further, the cell board edges of boards of the four direction of the cell board are multi-line section edges of boards.
Or in the cell board edges of boards of the four direction of the cell board, the cell board edges of boards in three directions are single line section plate
The cell board edges of boards on side, another direction are multi-line section edges of boards, and the multi-line section edges of boards have the recess to cell board sunken inside.
Or in the cell board edges of boards of the four direction of the cell board, the cell board edges of boards in a direction are single line section plate
The cell board edges of boards on side, the other three direction are multi-line section edges of boards, and a wherein multi-line section edges of boards have protruded to outside cell board
Projection.
Further, multi-line section edges of boards of the linear incision at least with the module unit plate in two cell boards of its both sides
It is adjacent.
Further, the linear incision is located at the centre of the technique edges between the cell board of its both sides.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention passes through the cell board in jigsaw upper edge cell board
Before edges of boards are cut, first cutting forms linear incision on the technique edges between two adjacent cell boards, makes linear incision both sides
Cell board edges of boards on, the i.e. each straight-line segment of the direction parallel with linear incision with the equidirectional straight-line segment of linear incision
On each point it is consistent at a distance from linear incision, uniform force when milling, therefore can avoid because of a certain straight-line segment and board
The distance of edges of boards is inconsistent to be led to milling process discontinuity and concavo-convex position occurs, it is ensured that the dimensional accuracy of cell board.
Cell board that can in any order on milling jigsaw after linear incision is made on jigsaw, cell board edges of boards are not in concave-convex position
It sets, the dimensional accuracy of cell board is high.
