Description

Micro coaxial cable connector assembly

[technical field]

The relevant a kind of micro coaxial cable connector assembly of the present invention relates in particular to a kind of micro coaxial cable connector assembly with the less conducting terminal of some volumes.

[background technology]

Anisotropically conductive glue, its characteristics have evident difference property at the resistance characteristic on what Z axle electrically conducting direction and XY insulation plane.When the difference of Z spindle guide energising resistance and XY plane insulating resistance value above certain ratio Hou, both can be described as favorable conductive anisotropy.The conducting principle: utilize conducting particles to connect the IC wafer and make it to become conducting with substrate electrode between the two, the while can be avoided conducting short circuit between adjacent two electrodes again, and only reaches the purpose in the Z-direction conducting.

Anisotropically conductive glue mainly comprises resin adhesive, conducting particles two large divisions.Resin adhesive function is except blocks moisture, and heat-resisting and insulation function is mainly electrode relative position between the immobile phase joint unit outward, and provides a compressing strength to keep the contact area between electrode and conducting particles.General resin is divided into thermoplastic resin and thermosetting resin two big classes.Thermoplastic mainly has the low temperature now, assembles the advantage of quick as easy as rolling off a log heavy industry.Thermosetting resin such as epoxy resin (Epoxy), Polyimide etc. have advantages such as high temperatrue stability and thermal expansivity and moisture absorption are low, and the advantage that its machinability is high is to adopt the most extensive material at present.

Aspect conducting particles, the Anisotropically conductive characteristic mainly depends on the pack completeness of what conducting particles.Though its conductance of Anisotropically conductive glue can improve with the increase of work conducting particles pack completeness.In addition, the particle size distribution of conducting particles and distributing homogeneity also can influence the Anisotropically conductive characteristic to some extent.Usually, conducting particles must have excellent particle size homogeneity and out of roundness, and is consistent with contact area between conducting particles to guarantee electrode, keeps identical conducting resistance, and avoids partial electrode not touch conducting particles simultaneously, and the situation that causes opening a way takes place.Common particle size range is between 3-5 μ m, and too big conducting particles can reduce the population of each electrode contact, also causes the contact of adjacent electrode conducting particles simultaneously easily and situation of short circuit; Too little conducting particles is gone into the problem of particle accumulation easily, causes distribution of particles density unequal.Aspect the kind of conducting particles, be main with metal dust and high molecular weight plastic ball surface coated metal at present.Plating gold, silver and ashbury metal etc. on the metal powder nickel (Ni) of common use, gold (Au), the nickel.

At present, micro coaxial cable connector assembly generally comprises: insulating body, be contained in conducting terminal in the insulating body, the cable that electrically connects with conducting terminal and coated insulation body be with the metal shell of shield electromagnetic interference.Conducting terminal adopts the tin silk to weld as scolder with cable and realizes being connected.But in welding process, bring higher fraction defective, particularly under the very little situation of the weld part of conducting terminal, such as: the weld part width of the conducting terminal that has only has 0.3-0.5mm, in welding process, is easy to the conducting terminal that fuses.

Therefore, be necessary to provide a kind of micro coaxial cable connector assembly to overcome the problems referred to above.

[summary of the invention]

Main purpose of the present invention is to provide a kind of micro coaxial cable connector assembly of optimizing manufacturing process.

For realizing above-mentioned purpose; The present invention can adopt following technical scheme: a kind of micro coaxial cable connector assembly; It comprises: plurality of conductive terminals, coat the insulating body of said conducting terminal and have the cable of some leads, said micro coaxial cable connector assembly also comprises the Anisotropically conductive glue that makes said lead and the electric connection of said conducting terminal.

Compared with prior art, the beneficial effect of micro coaxial cable connector assembly of the present invention is: optimize micro coaxial cable connector assembly production technology processing procedure, save man-hour, reduce fraction defective, reduce production costs.
