Abstract
Leaked electricity ameliorative way the invention discloses a kind of pcb board adjacent pores, for the needs of pcb board, prepare the drill of a variety of different diameter specifications, every kind of specification includes at least two drills；By the difference of diameter specifications, after the via of same diameter is drilled to the via on pcb board, then the via of another diameter is bored；During the via of same diameter is bored to pcb board, the adjacent adjacent pores on pcb board is drilled using different drills in order.The pcb board adjacent pores electric leakage ameliorative way of the present invention, can effectively prevent pcb board adjacent pores from leaking electricity, substantially increase the qualification rate of pcb board production.
Description
Technical field
The present invention relates to pcb board technical field of producing, specifically, is related to a kind of pcb board adjacent pores electric leakage improvement side
Method.
Background technology
Decoding deck class pcb board product, the hole count on pcb board is more, and number density of holes reaches every square metre 200,000 to 300,000, and
Via diameter is respectively less than 0.3mm, and pitch-row is 8 between 12mil.During the via bore process of existing pcb board, for phase
Two near vias, are to be drilled a via using same drill, this using same followed by another adjacent adjacent pores of brill
One drill easily causes drill and is heated, easily pcb board is caused to pull to adjacent pores continuous drilling mode, make pcb board base material by
Wound.The pcb board after production is set easily to cause copper ion migration to cause adjacent adjacent pores short circuit after electroplating.
The content of the invention
The technical problems to be solved by the invention are：A kind of pcb board that can effectively prevent pcb board adjacent pores from leaking electricity is provided
Adjacent pores electric leakage ameliorative way.
In order to solve the above technical problems, the technical scheme is that：
A kind of pcb board adjacent pores is leaked electricity ameliorative way, for the needs of pcb board, prepares the drill of a variety of different diameter specifications,
Every kind of specification includes at least two drills；
By the difference of diameter specifications, after the via of same diameter is drilled to the via on pcb board, then another diameter is bored
Via；
During the via of same diameter is bored to pcb board, different brills is used in order to the adjacent adjacent pores on pcb board
Knife drills.
Preferably, rig is controlled to capture needs automatically by controller, it is necessary to during tool changing the drill marshalling of preparation
Drill.
After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：
The pcb board adjacent pores electric leakage ameliorative way of the present invention, during the via of same diameter is bored to pcb board, to pcb board
On adjacent adjacent pores drilled in order using different drill, effectively prevent drill overheat and easily pcb board caused to pull, make
The problem of pcb board base material injury, the pcb board after production is not easily leaded to copper ion migration after electroplating and cause adjacent adjacent pores short
Road, substantially increase the qualification rate of pcb board production.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
The pcb board adjacent pores electric leakage ameliorative way of the present embodiment, for the needs of pcb board, prepares a variety of different diameter specifications
Drill, every kind of specification includes at least two drills.
By the difference of diameter specifications, after the via of same diameter is drilled to the via on pcb board, then another diameter is bored
Via.
During the via of same diameter is bored to pcb board, different brills is used in order to the adjacent adjacent pores on pcb board
Knife drills.
By the drill marshalling of preparation, it is necessary to during tool changing, rig is controlled to capture the drills of needs automatically by controller.
Specific control method can use following control method：Hole similar in diameter same position is identified, Shi Qi areas
The via of two kinds of diameters is divided into, using two drills, it will usually three addition identification codes after after the decimal point of diameter, carry out
Distinguish.
The pcb board adjacent pores electric leakage ameliorative way of the present invention, during the via of same diameter is bored to pcb board, to pcb board
On adjacent adjacent pores drilled in order using different drill, effectively prevent drill overheat and easily pcb board caused to pull, make
The problem of pcb board base material injury, the pcb board after production is not easily leaded to copper ion migration after electroplating and cause adjacent adjacent pores short
Road, substantially increase the production qualification rate of pcb board.
Specific experiment process and result of the test are as follows：
Take three KB (1.2T1 1), ultrasound ((1.2T1 1) and raw benefit (1.0T 1) four layers of substrate ULTRASONIC P P pressings
Plate；Design is made not using adjacent pores spacing as 5mil, 6mil, 7mil, 8mil, 9mil, 10mil respectively using diameter 0.35mm apertures
Same boring test.
Microscope observation aperture is carried out to bottom plate after drilling and pitch-row changes.50 times of observations are schemed under the microscope after drilling
Piece, two pitchs of holes are equal to and during less than 7mil from the point of view of picture, and hole occurs partially and deformation in hole position, and for using prior art
Not tool changing drills and the scheme using the application, is compared for the scheme of adjacent pores tool changing drilling, and the hole of adjacent pores tool changing drilling is inclined
Offset is significantly less than the offset of not tool changing drilling.Citing described above for best mode for carrying out the invention, wherein not detailed
The part carefully addressed is the common knowledge of those of ordinary skill in the art.Protection scope of the present invention is with the content of claim
It is defined, any equivalent transformation carried out based on technical inspiration of the invention, also within protection scope of the present invention.
Claims (2)
