Description
Technical field
The utility model is related to circuit board making field, more particularly to a kind of heavy copper production line test circuit plate.
Background technology
In assist side production process, when heavy copper, every plank has up to ten thousand holes or so to carry out in each liquid medicine tank
Process, after having processed, this some holes all becomes the plated through-hole having conductivity from non-metallic hole.But sink copper process
As long as in any one hole untreated good, all directly affect electric property so as to cause whole plate to be scrapped.And with wiring board
Aperture is less, and thickness of slab is thicker, and the liquid medicine of heavy copper cash is higher in the difficult treatment coefficient in the middle of hole, and it is heavy how more accurately to monitor
The performance condition of copper liquid medicine is most important, is generally adopted by backlight test inside industry, and method is set in the edges of boards of every sheet
One group of instrument connection is counted, instrument connection is cut after heavy copper, backlight detection inner hole deposition copper quality is carried out, but this method can only be examined
Measure the situation in indivedual holes, it is impossible to the situation of full wafer plate is more accurately fed back, cannot more detect the process capability of sliver.
Utility model content
The utility model provides a kind of heavy copper production line test circuit plate, whole to solve cannot to detect in prior art
The problem of the process capability of bar line.
For solving the above problems, as one side of the present utility model, there is provided a kind of heavy copper production line test circuit
Plate, including：Substrate, a length of 458mm of substrate, a width of 610mm, multiple through holes are drilled with substrate, and multiple arrays of openings become
The matrix of 3mm*3mm；Conducting metal is coated with the inwall of each through hole, it is conductive that each through hole is formed with first at its first end
Ring, each through hole are formed with the second conducting ring at its second end；Multiple through holes are divided into multiple test groups, in each test group
Through hole is conductively connected and number consecutively successively；Numbering in each test group is the first conducting ring of the through hole of odd number by being located at
First conducting ring of the first conductive metal band of the upper surface of substrate through hole big by 1 with the numbering than through hole that the numbering is odd number
Electrical connection；Numbering in each test group is that the second conducting ring of the through hole of even number is led by be located at the lower surface of substrate second
Second conducting ring of the metal ribbon through hole big by 1 with the numbering than through hole that the numbering is even number is electrically connected.
As all through holes of each test group are both turned on connection, so, this can be detected rapidly with universal meter measurement
The conductive aspects of test group inner via hole, if conductive represent that heavy copper is good, are so combined by different thicknesss of slab or pore size
The process capability of every bar line can detect that, moreover it is possible to be more accurately detected the liquid medicine performance of heavy copper cash, pre- to carry out in advance
Anti- calibration equipment and liquid medicine situation, have the characteristics that simple structure, low cost.

Specific embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As shown in Figure 1 to Figure 3, the utility model provides a kind of heavy copper production line test circuit plate, including：Substrate 1, base
A length of 458mm of plate 1, a width of 610mm, are drilled with multiple through holes 2, and multiple through holes 2 are arranged in the matrix of 3mm*3mm on substrate 1；
Conducting metal is coated with the inwall of each through hole 2, each through hole 2 is formed with the first conducting ring 3, each through hole at its first end
2 are formed with the second conducting ring 4 at its second end；Multiple through holes 2 are divided into multiple test groups, the through hole 2 in each test group according to
Secondary it is conductively connected and number consecutively；Numbering in each test group is the first conducting ring 3 of the through hole of odd number by being located at substrate
Upper surface the first conductive metal band 5 through hole 2 big by 1 with the numbering than through hole 2 that the numbering is odd number the first conducting ring 3
Electrical connection；Numbering in each test group is the second conducting ring 4 of the through hole of even number by being located at the second of the lower surface of substrate
Second conducting ring 4 of the through hole 2 big by 1 with the numbering than through hole 2 that the numbering is even number of conductive metal band 6 is electrically connected.
As all through holes 2 of each test group are both turned on connection, so, this can be detected rapidly with universal meter measurement
The conductive aspects of test group inner via hole, if conductive represent that heavy copper is good, are so combined by different thicknesss of slab or pore size
The process capability of every bar line can detect that, moreover it is possible to be more accurately detected the liquid medicine performance of heavy copper cash, pre- to carry out in advance
Anti- calibration equipment and liquid medicine situation, have the characteristics that simple structure, low cost.
As the utility model predominantly detects inner hole deposition copper wiring ability, therefore only the copper on original plate need to all be etched
Fall again to sink again copper, make graphics test.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvement that is made etc., should be included within protection domain of the present utility model.
