Referring to fig. 1-4, an embodiment of the present invention provides a method for manufacturing an antenna element module, including the following steps:

Further, in step S40, when there is a line pattern region in which the hanging point plating cannot be performed, in performing the laser etching process, the line pattern region in which the hanging point plating cannot be performed and the line pattern region in which the hanging point plating can be performed are kept connected to each other by the connection line 31 to form an entire region, and the entire region is used as the line pattern region for performing the subsequent step S50; and, after step S70, step S80 is further included to remove the first metal layer, the second metal layer and the third metal layer on the non-line pattern region in the whole region.
Preferably, step 20 is further included before step 30, and roughening treatment is performed on the surface of the antenna element module body.
The method for manufacturing the antenna element module according to the embodiment of the present invention is described in further detail below.
S10, an integrated antenna oscillator module body comprising the oscillator body 10 and the feed network circuit board body 20 is manufactured through integrated injection molding.
Specifically, according to the preset structure and size of the vibrator body 10 and the feed network circuit board body 20, the vibrator body 10 and the feed network circuit board body 20 are integrally injection molded by using high temperature resistant engineering plastics through an injection mold and injection molding equipment.
The high temperature resistant engineering plastic has small dielectric loss, is not higher than 0.005 at 1GHz, and has a thermal expansion coefficient close to that of a metal plating layer, such as glass fiber reinforced polyphenylene sulfide (PPS+40% GF is preferable), liquid Crystal Polymer (LCP), polyetherimide (PEI+45% GF is preferable) and the like.
After the integrated antenna oscillator module body is manufactured through injection molding, the antenna oscillator module body can be annealed to release the internal stress of the antenna oscillator module body.
S20, roughening the surface of the antenna element module body.
And (3) carrying out mechanical roughening treatment on the surface of the antenna oscillator module body, for example, obtaining proper roughness through sand blasting treatment, and removing residual sand blasting materials on the surface of the body through ultrasonic cleaning after the sand blasting treatment. The surface of the antenna element module body may be chemically roughened, for example, by an acidic solution. The roughening treatment aims to ensure the adhesive force of the subsequent metal layer and avoid the phenomena of coating falling off, foaming and the like.
S30, forming a first metal layer on the surface of the antenna element module body.
For example, a first metal layer is deposited on the body surface using an electroless plating process. Before the electroless plating treatment, the antenna element module body can be further subjected to pretreatment steps such as activation, and the pretreatment steps are all in the prior art.
Preferably, the thickness of the first metal layer is 1 μm or less, preferably 0.5 μm to 1 μm.
Preferably, the first metal layer is a nickel layer, or the first metal layer is a copper layer.
S40, carrying out laser etching treatment on the first metal layer, removing the first metal layer on the laser etching circuit, and forming a dividing line to separate a circuit pattern area and a non-circuit pattern area, wherein the circuit pattern area comprises circuit patterns of all oscillator circuits 11 and circuit patterns of all feed network circuits 21, and the oscillator circuits 11 and the feed network circuits 21 are directly connected through the laser etching treatment. When a circuit pattern area incapable of being subjected to hanging point electroplating exists, the circuit pattern area incapable of being subjected to hanging point electroplating and other circuit pattern areas capable of being subjected to hanging point electroplating are kept connected through a connecting circuit 31 to form an integral area, so that the integral area comprises at least one part of a non-circuit pattern area, namely a connecting circuit area between the circuit pattern area incapable of being subjected to hanging point electroplating and the circuit pattern capable of being subjected to hanging point electroplating, and the circuit pattern area and the non-circuit pattern area in the integral area are not completely separated during the laser etching treatment; the width of the connection line 31 is 0.5mm or more.
Specifically, firstly, designing laser engraving line patterns according to preset line patterns comprising all oscillator lines 11 and all feed network lines 21; and then carrying out laser etching treatment on the first metal layer by adopting 3D laser etching equipment according to a preset laser etching circuit pattern, and ablating the first metal layer on the laser etching circuit through laser irradiation to form a dividing line.
The dividing line is used to separate a line pattern region including all the vibrator lines 11 and all the feed network lines 21 and a non-line pattern region having no vibrator lines 11 and feed network lines 21 to block a conductive path between the line pattern region and the non-line pattern region. The width of the dividing line is, for example, greater than or equal to 0.3mm, i.e., the conductive path between the two regions is blocked. It is clear that when the connection line 31 is provided, at this step, there is no said dividing line in said whole area.
And S50, forming a second metal layer on the surface of the first metal layer of the circuit pattern area.
Specifically, a second metal layer is formed on the first metal layer in the circuit pattern area by electroplating through an electroplating process. And electrifying the circuit pattern area to ensure that the circuit pattern area is positively or negatively charged, and electroplating to form a second metal layer on the circuit pattern area. Since the non-line pattern region is blocked by the decomposed line, the second metal layer cannot be formed on the non-line pattern region by electroplating, so that the second metal layer is formed on the line pattern region by electroplating selectively. Obviously, when there is a circuit pattern area where the hanging point electroplating cannot be implemented, the first metal layer on the whole area is electroplated to form the second metal layer, that is, the first metal layer on at least a part of the non-circuit pattern area (connecting circuit area) in the whole area is also electroplated to form the second metal layer.
Preferably, the thickness of the second metal layer is 9 μm or more.
Preferably, the second metal layer is a copper layer. For example, pre-copper plating, bright copper plating and coke copper plating are sequentially performed on the circuit pattern region to form a second metal layer including a pre-copper plating layer, a bright copper plating layer and a coke copper plating layer.
S60, removing the first metal layer of the non-circuit pattern area.
Specifically, the antenna element module body with the first metal layer and the second metal layer in the circuit pattern area is processed by adopting a deplating process, and the first metal layer in the non-circuit pattern area is removed. For example, the whole antenna element module body is subjected to deplating treatment, and after the first metal layer is deplated and removed, the second metal layer is correspondingly deplated and removed to be approximately the same thickness, but the thickness of the first metal layer is far smaller than that of the second metal layer, so that the second metal layer is not influenced to play a function. Obviously, when there is a line pattern area where the hanging point plating cannot be performed, this step does not remove the first metal layer of the non-line pattern area (connection line area) in the entire area.
And S70, forming a third metal layer on the surface of the second metal layer.
Specifically, a third metal layer is formed on the second metal layer in the circuit pattern area by electroplating through an electroplating process. And electrifying the circuit pattern area, and electroplating to form a third metal layer on the circuit pattern area. Obviously, when there is a circuit pattern area where the hanging point electroplating cannot be implemented, in this step, the third metal layer is also electroplated on the second metal layer of the non-circuit pattern area inside the whole area.
Preferably, the third metal layer is 8 μm or more.
Preferably, the third metal layer is a tin layer.
And S80, removing the first metal layer, the second metal layer and the third metal layer on the non-circuit pattern area in the whole area.
Specifically, the first metal layer, the second metal layer and the third metal layer on the non-line pattern area in the whole area may be removed by a machining method, such as CNC (computer numerical control precision machining) machining, so as to remove the connection line 31, thereby separating the line pattern areas connected by the connection line 31.
According to the embodiment of the invention, through the steps, the first metal layer, the second metal layer and the third metal layer are sequentially overlapped on the surface of the antenna oscillator module body through the processing of chemical plating, laser etching and electroplating in the circuit pattern area, so that the circuit patterns of all oscillator circuits 11 and the circuit patterns of all feed network circuits 21 are integrated.
According to the manufacturing method of the antenna oscillator module, the oscillator circuit 11 and the feed network circuit 21 are selectively formed integrally in the circuit pattern area on the antenna oscillator module body formed through integral injection molding, chemical plating, laser etching and electroplating, so that complex assembly processes of the antenna oscillator and the feed network circuit board are avoided, the production efficiency is high, the cost is low, the weight is light, and the reliability and the stability of the antenna performance of the base station and the durability of the antenna are improved.
