In the process of test chip, it has comprised wafer sort, when wafer is detected, must utilize chip testing to use probe.Wafer is after making (Wafer Fabrication); And before not giving encapsulation as yet; Be to utilize contact or the internal circuit of chip on probe and the chip to contact; So that directly to the chip input signal or detect and read output valve, the crystal grain (die) of offering an explanation out to test above the wafer is non-defective unit or is defective products.In addition, in the packaging operation process, be to carry out the plain conductor tensile test, whether its needle tip that utilizes probe to be the drag hook shape catches on plain conductor, and applies to upper pulling force, come off easily with the test plain conductor, promptly is applied to online reliability test.Because of the guiding circuit of contact on chip or the wafer and packaging operation very fine; So that must carry out with the probe of fine acicular when carrying out above-mentioned electric test; So test often easily because of misoperation; And cause probe often to be lost destroying causing test to stop and changing, so this probe consumes in a large number.In addition, because producing, the probe moulding is difficult for, so many equipment costs of deriving.
Be the apparatus and method that the bar-shaped probe of multiple manufacturing is arranged now, yet those apparatus and method are neither to the greatest extent perfect now, promptly describe to those existing modes below.TaiWan, China is announced the I239401 patent of invention, and it is " a kind of wafer or chip testing are with novel probe forming method ", and it utilizes a high frequency mode of heating; Make the 0.1mm wire rod reach the temperature that is fit to red heat rapidly; With the line cutting mode this wire rod is carried out cutting again, the line after cutting directly is a straight probe base material, and this base material and make its front end form tip-like by an electrolytic processing method; Utilize edm to make cusp become spherical shape again; And with partly carrying out electroplating processes below the tip-like, be beneficial to be welded on the gripping member, can be gripped on the test probe on the parts and form by laser.
So, above-mentioned existing mode is that the needle tip of this probe and gripping member two are partly separately made moulding, thereafter again through integrally welded shape; So the welding processing procedure can improve needle tip and gripping member the joint interface resistance value and reduce the mechanical strength of probe; Therefore promptly can reduce the reliability that probe carries out electric test, and easy fracture damage, this manufacture process ridge is long and complicated in addition; Therefore improve cost of manufacture and man-hour and reduce production efficiency, and then cause probe to cost an arm and a leg.In addition; Because the diameter of needle tip is little; Be welded in the precalculated position of gripping member so be difficult for correct contraposition, therefore the needle tip of the every probe position that is welded in gripping member can't all fix identical, when those probes of clamping like this detect; The needle tip of probe is to be difficult for accurately to being positioned at the circuit on wafer or the chip, so reduce the testing efficiency and the degree of accuracy.

TaiWan, China is announced I292479 patent of invention " circuit test probe shaped device "; This invention is ground molding mode for improving single of machinery; Owing to during the manufacturing expenses of lapping mode, and, adopt the lapping mode difficulty of processing high along with probe diameter miniaturization day by day.Therefore this I292479 patent of invention utilizes the Electrolyzed Processing mode to carry out probe processing; This bottom that is installed on electrolytic cell is provided with minus plate; And utilize anchor clamps to grip many probes to be processed simultaneously, and utilize a straight line actuating structure to drive these anchor clamps and do upper and lower displacement, in order to the probe processing sections is soaked in the electrolyte; And the modulation machining voltage, and move these anchor clamps so that the end of probe is shaped to the tip.Yet this probe molding manufacture procedure mode is still identical with above-mentioned two patents of invention, and the needle tip and the gripping member two of probe are partly separately made moulding; Afterwards again through integrally welded; So have the shortcoming of above-mentioned two patents of invention equally, and this processing unit (plant) need be provided with accurate linear actuation structure and drive unit and upper and lower displacement control device simultaneously, and machining voltage adjusting device of complicated modulation; Therefore promptly can increase device is provided with cost, and process is consuming time loaded down with trivial details.
TaiWan, China discloses No. 200946283 application for a patent for invention case " the automatic continuous mill of microprobe "; This invention can only once be ground one for solving traditional mechanical formula grinding probe, and the problem that grinding operation can't be continuous, and Electrolyzed Processing mode long processing time; Therefore process velocity is severely limited; Therefore propose automatic continuous mill, processing plural probe simultaneously, and carry operation and the completion of grinding operation continuous synchronization.But; The mechanical lapping mode of this application for a patent for invention case can only be processed the probe base material with the footpath; Therefore still need carry out the procedure of processing of the needle tip and the gripping member of weld probe, and the precision of needle tip is limited, so this application for a patent for invention case still has the shortcoming of above-mentioned three patents of invention.In addition, this processing mode is the end that utilizes the mode needle point geochemical exploration pin base material of mechanical force, so this probe base material needs certain intensity, makes the diameter of probe that certain limitation arranged, and requires the probe of high fineness ratio to be processed with certain degree of difficulty.
Apparatus and method by the existing moulding probe of above-mentioned explanation can be learnt several shortcomings; Being mainly that aforesaid way all must separate the needle tip of probe with gripping member makes moulding; Again through being processed into one; So promptly can have the reliability that reduces the probe electric test, fracture damage easily, improve cost of manufacture and man-hour, reduce shortcomings such as production efficiency and probe shape precision be not good, and the process ridge of above-mentioned shaped device and method length and complicated; Increase cost so the device accuracy requirement is high, and can't make the probe of high fineness ratio.
