Description
Technical field
The present invention relates to board production technical field, more particularly to a kind of riveting method for improving riveted precision.
Background technology
The process for pressing of multilayer printed wiring board can be divided into pin positioning laminating technology according to the localization method between each layer
(PIN-LAM) and without pin positioning laminating technology (MASS-LAM), the former positioning precision is high, but efficiency is low, cost is high, is only applicable
In the production of high-layer, high-precision multilayer printed wiring board, although and the latter's positioning precision is relatively low, efficiency high, cost is low,
Therefore this method is that current most domestic producer carries out the process that multi-layer sheet production in enormous quantities is commonly used.
When pressing working procedure is pressed using MASS-LAM, needed before pressing using the first riveted laminate structure of rivet driver, and twin shaft
The homework precision of rivet driver and three axle rivet drivers is limited, when running into the laminate structure for having task difficulty (such as comprising thickness copper or
Structure of pseudobed plate etc.) or 8 layers and more than 8 layers of operation production plate when, easily produce layer scrap partially.Existing riveted flow is such as
Under：The technique for riveting flow of existing use twin shaft rivet driver or three axle rivet drivers is as follows：1st, in core plate and the edges of boards of prepreg
Bore at least eight rivet hole (wherein long side at least three, short side at least one is as shown in Figure 1)；2nd, according to lamination order by core plate with
Prepreg is stacked together, and core plate is corresponded with the rivet hole on prepreg, forms laminate structure；3rd, twin shaft or three axles
Two or three rivet holes that the red needle of rivet driver is inserted on laminate structure one side simultaneously carry out riveted, then riveted lamination knot one by one
Other rivet holes on structure.There is problems with above-mentioned riveting method：1st, because the rivet hole of riveted first is in straight line
On, it is impossible to a plane is fixed.When operation is to the laminate structure for having production difficulty, at the first hole of riveted, different cores
The plane of plate may produce relative slip, cause layer to scrap partially.2nd, after due to two axles and three axle rivet driver long-time uses, its
Stability can gradually be deteriorated, even if operation does not have the laminate structure of difficulty or the initial workpiece of the difficult laminate structure of operation not to occur
When layer is inclined, homework precision when can not also ensure follow-up batch production is not in deviation, and is only partially by X-RAY detection layers
A kind of detection method, any raising is not had to its homework precision；Prior art uses biaxial plane or three axle rivet machine operations, when
The larger laminate structure layer scrappage about 30% partially of task difficulty is run into, is also occurred even if the common laminate structure of operation scattered
Layer scrap partially.3rd, when previous process bores rivet hole to core material, if the rivet hole of the same position of two core plates has been offset,
It can not ensure that process is inclined by drift before being found in operation using existing riveting method.
The content of the invention
The present invention, which is directed to, to be had the inclined scrappage height of layer using existing riveting method and riveting can not be known during riveted
The problem of whether nail rushes inclined would know that whether rivet hole rushes inclined riveting during riveted precision and riveted there is provided a kind of improve
Conjunction method.
To achieve the above object, the present invention uses following technical scheme.
A kind of riveting method for improving riveted precision, comprises the following steps：
S1, according to lamination order the prepreg that core plate and edges of boards that edges of boards have bored rivet hole have bored rivet hole is layered in
Together, laminate structure is formed；The edges of boards of the core plate and prepreg are respectively provided with least eight rivet holes.
S2, two or three rivets by same edges of boards on two of rivet driver or three red needle correspondence insertion laminate structures
In hole.
It is preferred that, the rivet driver is twin shaft rivet driver or three axle rivet drivers.
S3, in laminate structure in a rivet hole of another edges of boards insert a pilot pin, the rivet hole be referred to as positioning
Rivet hole.
It is preferred that, the pilot pin is rivet.
S4, by rivet driver simultaneously the above-mentioned rivet hole for having inserted red needle of riveted.
S5, pass through rivet driver remaining rivet hole of riveted in addition to tacking nail one by one.
It is preferred that, the rivet hole of long edges of boards in preferential riveted laminate structure, then riveted short slab side rivet hole；Same edges of boards
Rivet hole then first riveted two ends rivet hole, then the rivet hole in the middle of riveted.
S6, the pilot pin taken out in tacking nail, pass through rivet driver riveted tacking nail.
Above-mentioned riveting method is preferred, in step s 2, by two of rivet driver or three red needles correspondence insertion lamination knots
On structure in two or three rivet holes of same long edges of boards；In step s3, the quilting rivet hole position is in another long edges of boards.
It is furthermore preferred that the quilting rivet hole position is in the centre of another long edges of boards.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention in the rivet hole of another edges of boards by placing
Pilot pin, each flaggy that pilot pin and red needle can be fixed in laminate structure respectively at grade, during can avoiding riveted
Slided between core plate and cause layer partially, even if the variable thickness of two core plates is caused in laminate structure, can also ensure homework precision during riveted
Do not influenceed by laminate structure, also can equally ensure its precision during batch production.If pilot pin can not be inserted in tacking nail,
It then can tentatively confirm that the rivet hole has been rushed partially, so as to realize the problem of whether rivet hole rushes inclined is being would know that during riveted.
Can will occur the inclined scrappage of layer after riveted by the inventive method and be reduced to zero, significantly reduce product rejection rate, improve
Production efficiency, reduces production cost.
