Abstract
The utility model discloses a flexible line way board soldering dish hinder tin structure should hinder the tin structure and include that it removed copper and form a plurality of tin bar that hinder that are used for blockking the tin cream flow to be close to the etching of non - soldering disk department at the soldering dish, wherein, a plurality of tin bar's of hindering length all is less than the critical length of soldering dish, a plurality of tin bar of hindering are two row at least settings, what be located same row hinders the equidistant setting of tin bar, and the tin bar that hinder between adjacent two rows are the interpolation and distribute.
Description
Technical field
The utility model is related to FPC technical field, the resistance tin knot of more particularly, to a kind of FPC soldering disk
Structure.
Background technology
After the soldering disk print solder paste of FPC, need to be put into heating in stove.But, high temperature can make soldering disk
In tin cream fusing.Tin cream after fusing has larger mobility.As shown in figure 1, the tin cream of flowing typically can be by soldering disk 1
It flow in non-soldering disk 2, thus affecting the normal work in other regions.
Utility model content
The main purpose of the utility model is：Offer is a kind of can be limited in set brush tin regional extent by tin cream
Interior, and do not result in the resistance tin structure of the FPC soldering disk of circuit disconnection.
For achieving the above object, the utility model provides a kind of resistance tin structure of FPC soldering disk, this flexible wires
The resistance tin structure of road plate soldering disk include soldering disk etch at non-soldering diskware remove copper and formed some for stopping tin
The resistance tin bar of cream flowing；Wherein, the length of some described resistance tin bars is respectively less than the critical length of soldering disk；Some described resistance tin bars
In at least two row's settings；Positioned at the resistance tin bar spaced set of same row, and the resistance tin bar between adjacent two rows is in that plug hole is distributed.
Preferably, some described resistance tin bars are in two row's settings, and the resistance tin bar between two rows is interspersed.
Preferably, some described resistance domed settings of tin bar, and the arch mouth of some described resistance tin bars is all towards soldering disk
Interior.
The resistance tin structure of the FPC soldering disk that the utility model provides, this resistance tin structure is passed through close in soldering disk
Critical part arranges some resistance tin bars, and some resistance tin bars are at least two row's settings, and the resistance tin bar of adjacent two row's parts is interspersed.
So, not only can strengthen hindering the effect of tin, and the circuit pathways of scolding tin disk and adjacent non-scolding tin weldment will not be separated.
Brief description
Fig. 1 is the structural representation of FPC soldering disk in prior art；
Fig. 2 is the structural representation of the resistance tin structure of the utility model FPC soldering disk.
The realization of the utility model purpose, functional characteristics and advantage will be described further in conjunction with the embodiments referring to the drawings.
Specific embodiment
It should be appreciated that specific embodiment described herein, only in order to explain the utility model, is not used to limit this
Utility model.
The utility model provides a kind of resistance tin structure of FPC soldering disk.
With reference to Fig. 2, Fig. 2 is the structural representation of the resistance tin structure of the utility model FPC soldering disk.This enforcement
A kind of resistance tin structure of FPC soldering disk that example provides.The resistance tin structure of this FPC soldering disk 1 includes：Including
Etching at soldering disk 1 is near 2, non-soldering disk goes copper to form some resistance tin bars 3 for stopping tin cream flowing.Wherein, if
The length of dry resistance tin bar is respectively less than the critical length of soldering disk 1；Some resistance tin bars 3 are at least two row's settings.Positioned at same row's
Resistance tin bar 3 between tin bar 3 spaced set, and adjacent two rows for the resistance is in that plug hole is distributed.
It should be noted that presence one is critical between soldering disk 1 and non-soldering disk 2.This critical model defining soldering disk 1
Enclose size.For avoiding the tin cream in soldering disk 1 to flow to non-soldering disk 2, in the present embodiment, FPC after high-temperature process
On increased some resistance tin bars 3.In order to save cost of material, some resistance tin bars 3 pass through etching on soldering disk 1 and go copper to be formed.
For avoiding resistance tin bar 3 to separate the current conduction between soldering disk 1 and non-soldering disk 2, in the present embodiment, some resistance tin bars 3
Length be respectively less than soldering disk 1 critical length, and two neighboring resistance tin bar 3 also will not be directly connected to side by side.Further, it is
Play multiple resistance tin to strengthen hindering tin, in the present embodiment, several resistance tin bars 3 are at least two rows' settings.Specifically, it is located at
Resistance tin bar 3 spaced set of same row, and the resistance tin bar 3 between adjacent two rows is in that plug hole is distributed.So, not only can play double
Hinder the effect of tin again, and the defect of resistance tin bar 3 isolation circuitry path can be overcome.
The resistance tin structure of the FPC soldering disk 1 that the utility model provides, this resistance tin structure is passed through to lean in soldering disk 1
Closely non-soldering Pan2Chu setting some resistances tin bar 3, some resistance tin bars 3 are at least two row's settings, and the resistance tin bar 3 of adjacent two row's parts
It is interspersed.So, not only can strengthen hindering the effect of tin, and the electricity of scolding tin disk and adjacent non-scolding tin weldment will not be separated
Road path.
Further, in order to strengthen hindering the effect of tin, in the present embodiment, some resistance domed settings of tin bar 3, and if
The arch mouth of dry resistance tin bar 3 is towards in soldering disk 1.It should be noted that the resistance tin bar 3 of domed setting has certain gathering
Effect, with respect to the resistance tin bar 3 of vertical bar type, the resistance tin bar 3 of arch more tin cream can be limited in soldering disk 1, thus strengthening
The effect of resistance tin.
These are only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or direct or indirect utilization
In other related technical fields, all include in the same manner in scope of patent protection of the present utility model.
