Definitions
- the present invention relates to a spiral probe and a manufacturing method thereof.
- Such a probe is disclosed in Patent Document 1.
- the probe described in Patent Document 1 has a pair of plungers connected by a spring.
- the conventional probes are only compatible with a pitch of 0.2 mm or more, and can be used only at 0.3 mm or more when arranged in a grid.
- the present invention provides a spiral probe that is easy to manufacture, can reduce the interval between probes when used as a probe unit, and can cope with further downsizing of electronic components and the like, and a method of manufacturing the spiral probe.
- a tapered tip that directly contacts the object to be inspected, a substantially hollow cylindrical tip-side main body extending in one direction from the root of the tip, and the tip-side main body are continuously integrated.
- the spiral probe is characterized in that the distal end side main body portion, the flexible portion, and the outer peripheral surface of the base end portion are aligned along the one direction.
- the distal end portion, the distal end side main body portion, the flexible portion, and the proximal end portion are all made of the same material, and the material is made of nickel, a gold alloy containing nickel or cobalt, or gold on a nickel film. It is a two-layer material or a nickel-tin alloy with laminated films.
- the outer peripheral surface has a substantially cylindrical shape in which the end on the tip side is closed by immersing the plating solution by immersing a portion other than one end of the thin wire member made of a thin metal wire in the plating solution.
- a uniform plating layer By forming a uniform plating layer, forming the tip portion at the end portion on the tip side where the plating layer is closed by machining, and removing the part of the plating layer to form the flexure portion.
- a distal end side main body portion and the proximal end portion are formed, and the thin wire member is immersed in an etching solution in a state having the distal end side main body, the flexure portion, and the proximal end portion, and all the thin wire members are melted.
- a method for manufacturing a spiral probe is provided.
- the other end of the thin wire member has a tapered shape.
- the removal of the plating layer is performed by laser processing.
- the outer peripheral surfaces of the distal end side main body portion, the flexure portion, and the base end portion are aligned along one direction, it is possible to provide an extra fine type probe. Therefore, when this probe is used as a probe unit, the interval between the probes can be narrowed, and it is possible to cope with further downsizing of electronic components and the like.
- the spiral probe is formed as an integral type using only the plating layer, the probe can be efficiently manufactured in a series of flows.
- a spiral probe 1 is provided with a tapered tip portion 2 that is in direct contact with an object to be inspected at the tip thereof.
- the probe 1 also includes a tip-side main body 3 that extends in one direction from the root of the tip 2 and has a substantially hollow cylindrical shape.
- the probe 1 also includes a flexible portion 4 that extends continuously in one direction continuously with the distal end side main body portion 3.
- the flexible portion 4 has an outer peripheral surface formed in a spiral shape and has a substantially hollow cylindrical shape.
- the probe 1 further includes a base portion 5 having a substantially hollow cylindrical shape that extends continuously in one direction continuously with the flexible portion 4.
- the spiral probe 1 having such a structure is manufactured as follows. First, as shown in FIG. 2, a thin wire member 7 made of a metal thin wire is immersed in a plating solution 6.
- the thin wire member 7 is, for example, copper and has a diameter of 50 ⁇ m.
- the plating solution 6 is immersed while leaving one end of the thin wire member 7 having a predetermined length.
- the electrode 8 is also immersed in the plating solution, and the electrode 8 and the thin wire member 7 are electrically connected via a power source 9. Nickel ions are present in the plating solution. Therefore, by applying a voltage, an electrolytic plating process is performed, and a plating layer 10 is formed on the outside of the thin wire member 7 as shown in FIG.
- the plating layer 10 has a substantially cylindrical shape in which the end portion on the front end side (lower side in FIG. 3) is closed, and the position of the outer peripheral surface is aligned along the longitudinal axis.
- the plating thickness can be controlled by the processing time and voltage (current).
- tip part 2 is formed.
- the tip 2 is formed at the tip of the plated layer 10 by machining using a known machine. Specifically, the end portion on the front end side of the plating layer 10 is processed into a tapered shape. At this time, if the end of the thin wire member 7 on the tip side is a tapered shape, it is preferable because it is easy to process. Then, as shown in FIG. 5, a part of the plating layer 10 is removed to form the bent portion 4.
- the bent portion 4 is formed by removing the outer peripheral surface of the plating layer 10 in a spiral shape with a laser using a known laser processing machine (laser trimming).
- the wavelength of the laser beam is preferably 532 nm, but may be changed according to the material of the plating layer 10. Simultaneously with the formation of the flexible portion 4, the distal end side main body portion 3 and the proximal end portion 5 are formed.
- the thin wire member 7 having such a distal end side main body 3, a bent portion 4, and a proximal end portion 5 is immersed in a selective etching solution (not shown).
- This selective etching solution dissolves only the material of the thin wire member 7 (copper in this example).
- the spiral probe 1 having the distal end portion 2, the distal end side main body 3, the deflection portion 4 and the proximal end portion 5 formed by the plating layer 10 remains (the state of FIG. 1).
- the spiral probe 1 is manufactured, only the plating layer 10 is used.
- the probe 1 is formed as an integral type using the plating layer 10, the probe 1 can be efficiently manufactured in a series of flows.
- the outer peripheral surfaces of the distal end side main body portion 3, the deflection portion 4 and the base end portion 5 are aligned along one direction. More specifically, the positions of the outer peripheral surfaces in all these portions are aligned along the longitudinal axis. That is, all the outer peripheral surfaces except the tip of the probe 1 are along a virtual line K parallel to the axis of the probe 1 (see FIG. 1). Therefore, the ultrafine probe 1 can be obtained. For example, when the plating thickness is 8 ⁇ m and the fine wire diameter is ⁇ 50 ⁇ m, the probe 1 having an outer diameter of ⁇ 66 ⁇ m can be obtained.
- the probes 1 are all made of the same material.
- the material nickel, a gold alloy containing nickel or cobalt, a material having a two-layer structure in which a gold film is laminated on a nickel film, or a nickel tin alloy can be used.
- the small probe 1 since the small probe 1 has a certain degree of elasticity, it can bend in the longitudinal direction.
- the large diameter part 5a can be formed in the outermost edge side of the base end part 5 by making one end part side of the thin wire
- it can apply to a various probe unit by making the base end part 5 into a different diameter.
- a probe unit 11 using such a probe 1 is formed on a support 16 having a four-layer structure in which a distal end guide member 12, a deflection portion guide member 13, a proximal end guide member 14, and an input / output extraction guide member 15 are stacked. It is formed by penetrating the probe 1. Note that the distal end guide member 12, the flexure part guide member 13, the proximal end guide member 14, and the input / output extraction guide member 15 may be made of the same material. In this case, the support 16 has a three-layer structure or a two-layer structure.
Abstract
Description
好ましくは、前記めっき層の除去はレーザ加工により行われる。
まず、図2に示すように、金属製の細線からなる細線部材7をめっき液6に浸漬する。この細線部材7は例えば銅であり、その直径は50μmである。めっき液6には、所定長さを有する細線部材7の一方の端部を残して浸漬される。めっき液には電極8も浸漬されていて、この電極8と細線部材7は電源9を介して電気的に接続されている。めっき液中にはニッケルイオンが存在している。したがって、電圧印加することにより、電解めっき処理が施され、図3に示すように、細線部材7の外側にはめっき層10が形成される。このめっき層10は、先端側の端部(図3では下側)が閉塞された略円筒形状で外周面の位置が長手軸線に沿って揃っている。また、めっき厚は処理時間や電圧(電流)にて制御できる。
