Abstract
The invention provides a method for interconnecting a micro-socket connector fine-pitch terminal and a base plate through an enameled wire. The method is characterized in that an interconnecting area of the enameled wire is subjected to tin coating in advance; then the electric resistance welding is performed through a micro electrode, wherein a certain of pressure is applied during the electric resistance welding so as to improve the contact effect and extrude bubbles; the enameled wire and a base plate are subjected to electric resistance welding, then the enameled wire is formed after welding, and finally the electric resistance welding is performed for the enameled wire and the micro-socket connector fine-pitch terminal. With the adoption of the method, the defect of manually welding the micro-socket connector fine-pitch terminal can be overcome, the defect caused by manual welding can be effectively decreased, the insufficient welding rate is reduced, and therefore, the yield and production efficiency of products can be increased.
Description
Technical field
The present invention relates to a kind of method adopting enamel-covered wire to realize Miniature connector thin space terminal and substrate interconnect.Particularly relate to the interconnection of Miniature connector thin space terminal and substrate in phased-array radar transmitting/receiving (T/R) assembly.
Background technology
Following phased-array radar will integrate antenna, transmitting/receiving (T/R) assembly, and in order to further improve packing density, reduced volume, Miniature connector thin space terminal will be widely used.At present, for Miniature connector thin space terminal, generally adopt thin head electric iron manual welding thin insulated wire to realize Miniature connector thin space terminal and substrate interconnect, because the distance between Miniature connector terminal, the space between levels are very little, manual welding operation is very inconvenient, also easily damage nook closing member or occur the defect such as short circuit and rosin joint, thus affecting finished product rate and reliability, reducing production efficiency.Therefore, the present invention proposes a kind of method adopting enamel-covered wire to realize Miniature connector thin space terminal and substrate interconnect, overcomes the limitation of thin insulated wire to Miniature connector terminal space, improves yield rate and enhances productivity.
Summary of the invention
The object of the invention is to a kind of method adopting enamel-covered wire to realize Miniature connector thin space terminal and substrate interconnect.
The technical solution that the present invention adopts for its technical problem of solution is: adopt enamel-covered wire as connected medium, reduce the requirement to Miniature connector terminal space, ensure that the insulating properties between terminal simultaneously; By warding off tin in advance to enamel-covered wire interconnect area, adopting microelectrode to carry out electric resistance welding to it, applying certain pressure in resistance welding process to strengthen contact effect and to extrude bubble; First carry out the electric resistance welding of enamel-covered wire and substrate, be soldered and rear enamel-covered wire formed, to reduce the stress be subject in use procedure, then carry out the electric resistance welding of enamel-covered wire and Miniature connector thin space terminal.
Compared with prior art, its remarkable advantage is in the present invention: overcome the limitation of thin insulated wire to Miniature connector terminal space, effectively reduces the defect that manual welding causes, reduces rosin joint rate, improves yield rate and the production efficiency of product.

Detailed description of the invention
Interconnection flow process of the present invention as shown in Figure 1.Concrete implementation step is as follows.
1, connected medium type selecting: for Miniature connector thin space terminal, selection enamel-covered wire is connected medium.Enamel-covered wire has good insulating properties, be easy to shaping, and thickness of insulating layer is very thin, meets the requirement to connected medium in the present invention.
2, enamel-covered wire wards off tin in advance: be that 0.1mm enamel-covered wire is cut out to required length by diameter, carry out coating removal to enamel-covered wire termination, then inserts and ward off Xi Guozhong and carry out warding off tin, and it is thin and even to ward off tin requirement tin layers.
3, thin space multi-core power terminal type selecting: according to the requirement of transmitting/receiving (T/R) assembly volume, weight, carries out rational type selecting to thin space multi-core power terminal.Thin space power supply terminal nook closing member spacing answers≤0.254mm.
4, the type selecting of microelectrode: for the feature of thin space power supply terminal and electric resistance welding to the requirement of material, microelectrode should possess good electric conductivity, have higher hardness.Select molybdenum electrode, electrode width≤0.18mm, two electrode spacings≤0.02mm.
5, the debugging of electric resistance welding parameter: size of current, weld interval, pressure size in electric resistance welding, directly affect the quality of welding, the life-span of electrode.The debugging of electric resistance welding parameter should be tested from small to large, detects welding quality in time, under the condition meeting welding requirements, should reduce electric current as far as possible, shortens weld interval, to reduce the accumulation of energy at welding region, and then damage welding region and electrode.
6, electric resistance welding: the electric resistance welding (see figure 2) of first carrying out enamel-covered wire and substrate, is soldered and forms enamel-covered wire afterwards, then carry out the electric resistance welding of enamel-covered wire and Miniature connector thin space terminal, see Fig. 3 after welding.
7, check: carry out appearance test under product 56 × microscope that butt welding connects, detect interconnectivity with universal meter.
