In contrast, metal shell 40 can be replaced and apply other printed circuit boards.
Fig. 2A is the perspective view for indicating the electric connection terminal of an embodiment according to the present invention, and Fig. 2 B is the section along A-A
Figure, Fig. 2 C are top view.
Electric connection terminal 100 includes: the core 110 of metal material；Along core 110 welding surface marginal position with predetermined width
The solder of formation rises anti-stops 120；And it is formed in the gold on the outer surface of the core in addition to solder rises anti-stops 120
Belong to shell (shell) 130.
Electric connection terminal 100 with a thickness of 0.05mm to 0.2mm, width and length then can be in the range of 1mm to 5mm
The shape of quadrangularly is designed, however is not limited to this.
In addition, for ease of manufacturing and reducing manufacturing cost, the thickness of core 110 is more larger than the thickness of shell 130.
Referring to Fig. 2 B, core 110 can be made of copper or copper alloy or ferroalloy；Shell 130 can be overlying on nickel by plating or nickel closes
Gold or billon coating layer 132 on golden coating layer 131 are constituted, or may be that plating is overlying on nickel or nickel alloy coating layer 131
On tin coating layer or silver-colored coating layer constitute, formed by batch plating.
In view of the material of the hardness of core 110 itself, price, electric conductivity or shell 130, core 110 is preferably the copper such as phosphor bronze
Alloy, however this is not limited to according to the purposes of electric connection terminal 100.
Core 110 has thinner thickness and planar sheet shape, for the economy cut when manufacturing electric connection terminal 100
Property, it is cut using fritter (DiCing) cutting machine, thus its flat shape is quadrangle.
Therefore, each corner of core 110 is formed as right angle, but can be slightly distorted in grinding technics as arc-shaped.
Batch plating is carried out by all surfaces of the core 110 other than solder rises anti-stops 120, it being capable of reliable landform
At uniform and continuous shell 130.
Here, the Ni-Pd alloy as nickel alloy can be used for shell 130, and can be used and make to increase the hardness of shell 130
For the gold cobalt alloy of billon.In this way, making the hardness of shell 130 greater than the conductive pattern 12 of the circuit substrate 10 of pure copper foil material
Hardness, therefore the folder 30 of the biggish Copper alloy material of hardness will not be directly contacted with the conductive pattern of the lesser pure copper foil material of hardness
Case 12, but be mechanically contacted with the biggish electric connection terminal 100 of hardness and be electrically connected, it is possible thereby to the friction with folder 30
Middle mechanical system and electric mode protect the conductive pattern 12 of circuit substrate 10.
Also, the easy corrosion by external environment of the conductive pattern 12 of pure copper foil material, but the electricity contacted with folder 30
The shell 130 of connection terminal 100 is made up of golden plating or billon plating, therefore will not be rotten if exposed to outside
Erosion, so that the reliability of electrical contact and Mechanical Contact be made to improve.
Here, what pure copper foil indicated is as the few as possible copper foil of contained impurity for being usually applied to circuit substrate.
In above-described embodiment, although with the conductive pattern 12 of the circuit substrate of pure copper foil material for example, pure
On the conductive pattern 12 of copper foil material successively plated nickel and gold FPCB conductive pattern in the case where, can be in electric connection terminal 100
It is upper to form relatively thin nickel coating layer 131 and golden coating layer 132, to reduce manufacturing cost.
In this case, it is possible to which the nickel coating layer 131 of shell 130 and the thickness of golden coating layer 132 is made to be greater than the conduction of FPCB
The nickel of pattern 12 and the thickness of gold.
When welding by soldering paste, the solder of melting is easy diffusion or soaring on the face for being plated with gold or billon.
The solder anti-stops 120 that rises is formed to have and prevents fusion welding along electric connection terminal when welding by soldering paste
The outer surface diffusion or soaring effect of 100 gold or billon, it is preferred that electrical isolation can be applied, have acceptable welding warm
The heat resistance of degree and the polymer resin that can not be welded, for example, epoxy resin, silica gel or photoresists (photo sensitive
resist)。
The solder anti-stops 120 that rises is to be led to by the polymer resin, rubber or photoresists of liquid in the marginal position of core 110
Printing is crossed after formation, passes through hardening and pastes formation.
In view of being fused to the amount and shape of the soldering paste of shell 130, the rise height of anti-stops 120 of solder is higher than shell 130
Highly, therefore relative to shell 130 it raises upward.
Solder rises the height of anti-stops 120, citing can in 0.01mm to 0.1mm hereinafter, width can 0.1mm extremely
0.8mm, however it is not limited to this.
In addition, solder rises, anti-stops 120 is formed as marginal position left and right directions and upper and lower in the welding surface of core 110
To symmetrical, the shaking of electric connection terminal 100 when welding by solder paste reflow is thereby reduced.
The rise composition material of anti-stops 120 of solder can not be welded by soldering paste, and can play the role of dam (dam) with
This prevents from fusion welding from can not cross solder riseing anti-stops 120 in reflow soldering, and can provide and can play dam (dam)
The solder paste amounts and shape of effect.
The solder anti-stops 120 that rises forms the closed loop configuration of quadrangle, and a small amount of fusion weld along the marginal position of core 110
Material can flow out to outside from closed loop, so that the upper surface of conductive pattern 12 is easy to weld with electric connection terminal 100.
Soldering paste is only coated on solder and rises the inside of anti-stops 120, and is less than the size of conductive pattern 12 and is climbed by solder
Rise the size that anti-stops 120 is formed by internal area, thus the upper surface of conductive pattern 12 with below electric connection terminal 100 easily
In welding, however it is not limited to this.
Based on above structure, even if the thinner thickness of electric connection terminal 100, climbed since the solder of melting can not cross solder
Anti- stops 120 is risen, so folder 30 is only in electrical contact with the gold of shell 130 or billon coating layer in the upper surface of electric connection terminal 100,
Therefore the electrical contact of electric connection terminal 100 and folder 30 and Mechanical Contact have reliability.
Fig. 3 is the sectional view for indicating to be applied to the state of the conductive pattern 12 of circuit substrate.
For the surface mount for being easy to electric connection terminal 100,100 spool of electric connection terminal is batched and is mentioned in packed carrier
For, and by vacuum pick and surface mount is on the soldering paste 50 on the conductive pattern 12 of circuit substrate 10, and pass through Reflow Soldering
Luggage is tapped into match.
The upper surface of electric connection terminal 100 and following shape are different due to solder rises anti-stops 120, therefore are easy to
Spool batches.
Soldering paste 50 on conductive pattern 12 is formed as corresponding with the solder size and shape of 120 inside of anti-stops that rises, by
, in welding, soldering paste 50 is located at solder and rises the inside of anti-stops 120, and can prevent solder from riseing by side for this.
Therefore, electric connection terminal 100 only returns on the core 130 for anti-120 inside of stops of riseing positioned at solder by soldering paste
Fluid welding connects.
In order to keep shaking of the electric connection terminal 100 in reflow soldering smaller, the shape of soldering paste 50 can be round, four sides
Shape or symmetrical shape.
In this case, the elastic clip 30 for being assemblied in metal shell 40 is mechanically contacted with electric connection terminal 100,
As a result, folder 30 with conductive pattern 12 mechanically and electricity mode is connect and elastic connection.
Fig. 4 simply shows an embodiment of the manufacturing method of electric connection terminal.
Prepare the copper sheet 1110 that about horizontal × perpendicular × thickness is 100mm × 100mm × 0.15mm degree plane, is cut
It is designed as the part of the core 110 of electric connection terminal 100.For example, the dotted line that drawing reference numeral 1 indicates forms the boundary of each core 110
(both, marginal positions) is then applicable as cutting line in cutting technique.
Print the epoxy resin of liquid and heat resistance with predetermined width to two sides centered on cutting line 1, and by high temperature
Or ultraviolet light is hardened, and solder is consequently formed and rises anti-stops 120.
Then, right angle cuts are carried out using cutting machine (dicing saw) or cutting blade on the basis of cutting line 1, and led to
Grinding technics etc. is crossed to remove the burr (burr) generated by cutting.
The core 110 of quadrangle form made of right angle cuts forms solder along the marginal position of its one side with preset width
