Abstract

The utility model discloses a solder mask structure of a connector contact. The solder mask structure comprises a contact area, an installation part and a soldering area, and is provided with a solder mask strip, wherein the tail part of the soldering area is defined as a non-soldering position; the solder mask strip is covered on the tail part of the soldering area. A soldering flux can be prevented from being scattered onto positions which are not required to be stained with the soldering flux, i.e., the installation part and the contact area, in a soldering process, so that the installation part and the contact area on the contact are protected effectively. The solder mask structure has low process difficulty, is easy to implement, and is suitable for batch production.

Description

The solder mask structure of connector contact
Technical field
The utility model relates to a kind of connector welding field, relates in particular to a kind of solder mask structure of connector contact.
Background technology
For the connector contact tail end (pin, bonding wire cup etc.) of termination mode for welding, need tail end is handled, make it to have good welding performance, promptly have good solderability.In welding process, because capillarity, scolder produces cross flow (promptly sprawling) at solder side, and is wetting from making solder side, and because of diffusion, the scolder atom will be diffused on the weld metal, thereby forms alloy, reaches the welding purpose.But when the connector contact size hour, scolder can cross flow to other positions of contact, like installation portion and contact zone, thereby influence connector performance, even causes the connector performance inefficacy.On the other hand,, thereby the welding position scolder is reduced, can form rosin joint most probably because other positions of contact are arrived in the scolder cross flow.
In order to address the above problem, then need block other positions that need not weld that scolder is climbed to contact, at present commonly used have two kinds of ways:
The one, contact is adopted local method of plating; Promptly between contact zone or contact zone and tail end welding position, different coating is set; Guarantee that afterbody has good solderability, and the regional plating weldability between contact zone or contact zone and the afterbody is bad, thereby stops the scolder cross flow.Local electroplating method commonly used has: brush plating, spraying plating, plating etc., but because contact is smaller, require brush plating head or spraying plating head also necessary little accordingly, this will strengthen manufacture difficulty, has only few countries can grasp this technology at present.Because the cross flow effect of plating bath can make the local area size of plating be difficult to control, often do not reach requirement in addition.
The 2nd, utilize laser ablation on contact, to form a groove or oxide layer, stop scolder to continue to climb, guarantee that scolder can cross flow not arrive prohibited area.Though this method has been avoided the technical difficulty of local plating,, thereby influence connector performance because etching might have influence on physical property, mechanical performance and the surperficial environmental resistance of contact to the effect of contact matrix.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of solder mask structure of connector contact, and this structure can stop the cross flow phenomenon of scolder, and electrical property, the environmental resistance of protection contact are not damaged.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of solder mask structure of connector contact; Comprise contact zone, installation portion and weld zone; Be provided with a resistance welding; The afterbody of definition weld zone is non-welding position (afterbody is the joint portion between installation portion shown in Fig. 1 and the weld zone), and said resistance welding is covered in the afterbody of said weld zone, thus said resistance welding be able to enough stop scolder from the afterbody cross flow of weld zone to said installation portion and contact zone.
As the further improvement of the utility model, the raw material of said resistance welding adopts a kind of in solder resist, paint and the printing ink.
Adopt a kind of resistance welding raw material that on the tail surface of said weld zone, applies in spraying, printing and the sputtering method in the utility model.
The beneficial effect of the utility model is: the afterbody through the weld zone on connector contact is provided with the resistance welding; In welding process; Can stop the scolder cross flow to the position that need not be stained with scolder, i.e. installation portion and contact zone, thus protected installation portion and the contact zone on the contact effectively.The utility model technology difficulty is little, realizes easily, is fit to produce in batches.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment to the solder mask structure of the connector contact of the utility model is elaborated with reference to the accompanying drawings.
The solder mask structure of a kind of connector contact of the utility model; Comprise contact zone 1, installation portion 2 and weld zone 3; Be provided with a resistance welding 4; The afterbody of definition weld zone is non-welding position, and said resistance welding is covered in the afterbody of said weld zone, thus said resistance welding be able to enough stop scolder from the afterbody cross flow of weld zone to said installation portion and contact zone.
In the present embodiment, adopt a kind of in spraying, printing and the sputtering method on the tail surface of said weld zone, to apply resistance welding raw material, and the raw material of said resistance welding adopt a kind of in solder resist, paint and the printing ink.
