Description
Technical field
The present invention relates to a kind of manufacture field of mobile communication devices, particularly relate to a kind of welding method of coaxial cable outer conductor and the application of the method.
Background technology
Current radio-frequency devices is often used coaxial cable in a large number as parts such as oscillator, power splitter and phase shifters and is electrically connected, and the outer conductor of coaxial cable often adopts soldering mode to be connected with the metal surface of radio-frequency devices.The metal surface of radio-frequency devices is generally divided into three kinds: can the metal base surface of direct soldering; Can the metal surface of soldering to what obtain after the plating of metallic matrix entirety; What on metallic matrix, parcel plating obtained can the metal surface of soldering.
The metal base surface of direct soldering precisely can cannot control spot area when welding with coaxial cable outer conductor, welding resistance beyond butt welding point region can not be accomplished, the scolding tin of flowing spreads and can cause outward appearance unsightly, and scolding tin flowing makes it easily to produce failure welding soon.In addition, often material cost is expensive for the metallic matrix of solderability, causes parts cost high.
To the plating of matrix entirety obtain can exist equally beyond butt welding point region cannot welding resistance the metal surface of soldering, solder joint is unsightly and easily produce the shortcoming of failure welding.And the complicated procedures of forming such as overall electrotinning often needs at the bottom of pickling, washing, heavy zinc, copper facing, pickling, washing, zinc-plated, oven dry.Its complex procedures, efficiency is low, produces waste water and gas, has stronger contaminative, so cause its processing cost higher.
And can soldering region in order to obtain local on metallic matrix, conventional has following several scheme: one: adopt for local welding position press zinc-plated copper piece or copper piece, and this mode complex structure, the reliability that presses is low, produces the defect of loose contact simultaneously.Its two: adopt parcel plating mode; but need non-electroplating part to adopt the plating of lacquer special type coating protection before plating, after having electroplated, adopt chemical way to remove coating, this mode inefficiency again; coating cost is not low, causes last price to be not less than overall plating.Its three: coating bath is immersed at the position of needs electroplating surface, and the electroplated component number that the unit interval produces is less, and efficiency is very low, and cause its cost to be also not less than overall plating, wherein efficiency is a part maximum in electroplating cost.Although the local adopting above several scheme to obtain the metal surface of soldering also can solve welding resistance problem and solder joint bad order problem, there is shortcoming in various degree in it respectively.
In reality, the communications field considers for electric property and cost, a large amount of employing aluminum alloy materials is as shielding cavity, and aluminium alloy itself not can soldering material, thus, when coaxial cable needs to weld with the surface of the device of aluminium alloy cavity and so on, when particularly occurring in the connectivity port place of conductor and cavity, just nature will meet with above-mentioned problem.
Further, based on the existing technical characterstic about coaxial cable welding, even if above-mentioned aluminium alloy device adopts the mode of zinc-plated copper piece (or the copper piece) that press, or adopting parcel plating mode to obtain local can soldering region, but still mainly relying on manual operation when being welded with coaxial cable by transformed aluminium alloy device, being difficult to enhance productivity and reduce the labour cost in production further.
