Background
In the manufacturing process of the multilayer printed circuit board, the surface treatment needs to be carried out on the inner copper surface so as to enhance the adhesion between the copper surface and the prepreg and prevent the interlayer stripping. The traditional treatment process is to oxidize the copper surface to form acicular crystals of copper oxide and cuprous oxide on the copper surface, increase the surface area of the copper foil and convert the polarity of the copper surface, thereby enhancing the adhesion between the copper foil and the prepreg.
The oxide layer formed in the prior art is attacked by acid liquor in the subsequent process treatment, so that the local delamination around the via hole is easily caused, and the so-called pink ring phenomenon appears. In order to solve the problem of "pink ring", a copper surface roughening agent of HSO4 — H2O2 system was developed to replace the conventional oxidation treatment. The copper surface roughening treatment agent is formed by adding additives such as nitrogen-containing heterocyclic compounds, halogen ions, ethylene oxide polymers and the like. The liquid medicine forms an organic metal film while coarsening the copper surface, and the film not only can react with certain groups of the prepreg to form chemical bonding force, but also can effectively resist the attack of acid liquor, thereby preventing the occurrence of pink ring.
Chinese patent publication No. CN104694909B discloses a copper surface roughening agent, which contains guanidine substances, wherein the guanidine substances can be complexed with monovalent copper ions on the copper surface, and strongly adsorbed on the side wall of the microscopic concave surface of copper, so that divalent copper continuously bites into the metal copper in the depth direction, and the copper foil surface can generate dense fine needle-like protrusions, which have a strong anchoring effect, and simultaneously, a uniform and dense organic metal film is formed on the copper foil surface, so that the bonding strength between the copper foil and the polyimide film can be greatly improved. However, the above patent does not provide copper product roughening equipment dedicated to the roughening agent of guanidine substances, and the use of such roughening agent is only limited to conventional spraying and soaking.
The invention discloses a roughening treatment device for copper foil of a circuit board, which comprises a microetching tank, an electrolytic deposition pool, a plurality of transmission rollers, a water washing roller and a liquid cooling roller, wherein the transmission rollers for conveying and traveling the copper foil are arranged at the microetching tank and the electrolytic deposition pool, the copper foil sequentially passes through the microetching tank, the electrolytic deposition pool, the water washing roller and the liquid cooling roller, a first spraying device and a second spraying device are symmetrically arranged in the microetching tank, the first spraying device and the second spraying device are symmetrically arranged at two sides of the copper foil, and a titanium electrode plate is arranged in the electrolytic deposition pool. However, the technical solution of the above patent has the following problems: only the copper foil with regular shape can be processed, the copper sheet body with irregular shape can not be processed, and the copper surface is processed by the conventional spraying method, so that the coarsening degree is difficult to be effectively controlled.

Further, the roughening spraying device 200 may further have a third spraying device and a third water absorption device in sequence behind the second water absorption device 250, and a fourth spraying device and a fourth water absorption device in sequence behind the second water absorption device, and so on.
Further, a detection probe 300 is arranged between the coarsening spraying device 200 and the placing area and is used for detecting the distance between the two clamping blocks 131; or each clamping mechanism 130 is provided with a distance sensor for measuring the distance between the two clamping blocks 131.
Further, according to the test, the optimal process conditions for the roughening treatment are as follows: 10% of organic copper, 5% of organic acid, 1% of guanidine compound and 0.1% of organic amine, wherein the pH value is less than 1, and the temperature is 25-35 ℃. Wherein, the organic amine can improve the dissolution stability of copper and promote the uniformity of copper etching.
The operation method and principle of the invention are as follows:
an operator manually pulls open the clamping block 131 of the clamping mechanism 130, places the copper sheet body on the clamping mechanism 130, and releases the clamping block 131 to fix the copper sheet body. The distance between the two clamping blocks 131 is detected by the detection probe 300 or a distance sensor, so as to determine the distance dimension of the copper sheet along the direction of the conveyor belt 120. And determining the duration of the spray coarsening according to the distance size of the copper sheet body. When the copper sheet is about to travel below the first injection device 220, the elevator 210 descends, the piston 222 of the first injection device 220 moves downward, the gas in the cylinder 221 is pressed, and the air pressure pushes the roughening agent to be sprayed out from the flat injection nozzle 224. Along with the uniform movement of the conveyor belt 120, the roughening agent is uniformly and vertically sprayed on the copper sheet body, and the upper surface of the copper sheet body is roughened once. When the copper sheet leaves the lower part of the first spraying device 220, the lifter 210 rises, the piston 222 of the first spraying device 220 moves upwards, the gas pressure in the cylinder 221 drops, the coarsening agent enters the cylinder 221 from the liquid supplementing port for supplementation, and the unidirectional through-flow structure 225 prevents the outside air from entering. Because the mass of the gas sealed in the cylinder 221 is constant and the stroke of the piston 222 is constant, the liquid level in the cylinder 221 is constant after each liquid supplement, and the air pressure during each injection is also constant, so that the speeds of the injection of the coarsening agent are consistent.
When the copper sheet body is about to move below the first water absorption device 230, the copper sheet body at the rear part is about to move below the first spraying device 220, the elevator 210 descends at the moment, the first spraying device 220 performs the same treatment on the next copper sheet body, and the water absorption column 233 of the first water absorption device 230 is in contact with the copper sheet body to absorb the residual liquid on the copper sheet body.
When the copper sheet sequentially passes through the second spraying device 240 and the second water absorption device 250, the above process is repeated to perform a secondary roughening treatment. Similarly, as the number of stages of the device increases, three times of roughening processing, four times of roughening processing, and the like can be completed. Each time the elevator 210 descends, all of the spraying devices and the water suction devices simultaneously process the respective underlying copper sheet pieces.
Through the conveying speed of adjustment conveyer belt 120, can adjust the volume of the coarsening agent that sprays on the copper sheet body at every turn to adjust the degree of coarsening at every turn, set up the processing of different numbers of times according to the technology demand simultaneously, further control the degree of coarsening. Compared with spraying and soaking, the vertical spraying can promote the coarsening process to be carried out towards the vertical direction, the dosage of coarsening at each time is controlled, coarsening is carried out for multiple times, and the residual liquid of coarsening at each time is sucked away, so that the bottom area formed after last coarsening can be deeply bitten into by coarsening at each time, and the coarsening effect is further improved.
The present invention has been described in detail with reference to the preferred embodiments thereof, and it should be understood that the present invention is not limited thereto, but includes any modifications, equivalents, and improvements within the spirit and scope of the present invention.
