請參照第8圖,其繪示依照本發明一實施例之電路板夾持及拉伸的控制方法的流程圖。電路板夾持及拉伸的控制方法包括下列步驟S101~S110,請參照第1圖一併說明。在步驟S101中,分別以一固定夾具120、一第一夾具130、一第二夾具140及一第三夾具150夾持一電路板10之對角的四個位置11~14。在步驟S102中,控制第一夾具130及第三夾具150朝一第一軸向X拉伸電路板10,以及控制第二夾具140及第三夾具150朝一第二軸向Y拉伸電路板10。在步驟S103中,接收一拉伸資訊,以供判斷電路板10於第一軸向X及第二軸向Y上被拉伸的距離及對電路板10拉伸的力量是否超出一設定值。在步驟S104中,當接收到拉伸資訊之後,處理單元180判斷電路板10被拉伸的距離是否大於或等於電路板10在第一軸向X與第二軸向Y上的尺寸相關設定值(例如0.3%以下)。例如,電路板10在第一軸向X與第二軸向Y上的尺寸皆為500毫米,則設定電路板10被拉伸的距離小於1.5毫米,以避免電路板10拉伸時過拉而造成基板變形或位置偏移的問題。在步驟S105中,當電路板10被拉伸的距離大於或等於設定值時,如上所述,鎖固第一軸向拉伸機構160及第二軸向拉伸機構170之可活動桿體,以固定第一夾具130、第二夾具140以及第三夾具150的拉伸位置。接著,在步驟S106中,緊閉第一軸向拉伸機構160及第二軸向拉伸機構170的閥門開關,以固定第一夾具130、第二夾具140以及第 三夾具150於此固定拉伸位置下的拉伸力量。 Please refer to FIG. 8 , which is a flow chart of a method for controlling clamping and stretching of a circuit board according to an embodiment of the invention. The method for controlling the clamping and stretching of the circuit board includes the following steps S101 to S110, which are described with reference to FIG. In step S101, four fixed positions 11 to 14 of a circuit board 10 are sandwiched by a fixing jig 120, a first jig 130, a second jig 140 and a third jig 150, respectively. In step S102, the first jig 130 and the third jig 150 are controlled to stretch the circuit board 10 toward a first axial direction X, and the second jig 140 and the third jig 150 are controlled to extend the circuit board 10 toward a second axial direction Y. In step S103, a stretching information is received for judging whether the distance that the circuit board 10 is stretched in the first axial direction X and the second axial direction Y and the force to stretch the circuit board 10 exceed a set value. In step S104, after receiving the stretching information, the processing unit 180 determines whether the distance that the circuit board 10 is stretched is greater than or equal to the size-related setting value of the circuit board 10 in the first axial direction X and the second axial direction Y. (for example, 0.3% or less). For example, if the size of the circuit board 10 in the first axial direction X and the second axial direction Y is 500 mm, the distance of the circuit board 10 is set to be less than 1.5 mm to avoid over-pulling when the circuit board 10 is stretched. Problems that cause substrate deformation or positional shift. In step S105, when the distance that the circuit board 10 is stretched is greater than or equal to the set value, as described above, the movable rod body of the first axial stretching mechanism 160 and the second axial stretching mechanism 170 is locked. The stretching positions of the first jig 130, the second jig 140, and the third jig 150 are fixed. Next, in step S106, the valve switches of the first axial stretching mechanism 160 and the second axial stretching mechanism 170 are tightly closed to fix the first clamp 130, the second clamp 140, and the first The tensile force of the three clamps 150 at this fixed stretch position.
接著,在步驟S107中,當處理單元180判斷電路板10被拉伸的距離小於電路板10在第一軸向X與第二軸向Y上的尺寸相關設定值時,處理單元180進一步判斷對電路板10拉伸的力量單位面積是否大於或等於拉力相關設定值(例如0.3~2公斤)。若否,回到步驟S104,重複判斷電路板10被拉伸的距離是否超過一設定值。在步驟S108中,當對電路板10拉伸的力量單位面積大於或等於2公斤時,如上所述,緊閉第一軸向拉伸機構160及第二軸向拉伸機構170之閥門開關,以固定第一夾具130、第二夾具140以及第三夾具150的拉伸力量。在步驟S109中,鎖固第一軸向拉伸機構160及第二軸向拉伸機構170的可活動桿體,以固定第一夾具130、第二夾具140以及第三夾具150於此固定拉伸力量下的拉伸位置。因此,第一夾具130、第二夾具140與第三夾具150可依照上述拉伸資訊適當地調整電路板10被拉伸的面積範圍。 Next, in step S107, when the processing unit 180 determines that the distance that the circuit board 10 is stretched is smaller than the size-related set value of the circuit board 10 in the first axial direction X and the second axial direction Y, the processing unit 180 further determines Whether the unit area of the tensile force of the circuit board 10 is greater than or equal to the tension-related setting value (for example, 0.3 to 2 kg). If not, returning to step S104, it is repeatedly determined whether or not the distance to which the board 10 is stretched exceeds a set value. In step S108, when the unit of force for stretching the circuit board 10 is greater than or equal to 2 kg, as described above, the valve switches of the first axial stretching mechanism 160 and the second axial stretching mechanism 170 are tightly closed, The tensile force of the first jig 130, the second jig 140, and the third jig 150 is fixed. In step S109, the movable rods of the first axial stretching mechanism 160 and the second axial stretching mechanism 170 are locked to fix the first clamp 130, the second clamp 140, and the third clamp 150. Stretching position under the force. Therefore, the first jig 130, the second jig 140, and the third jig 150 can appropriately adjust the range of the area in which the circuit board 10 is stretched in accordance with the above-described stretching information.
由上述的說明可知,當電路板10被拉伸的距離超出一設定值時,雖然對電路板10拉伸的力量未超過設定值,但是為了避免電路板10過拉,則固定夾具120的拉伸位置。反之,當電路板10被拉伸的距離未超出一設定值,進一步對電路板10施加更大拉伸的力量,直到電路板10被拉伸的距離超出設定值或對電路板10拉伸的力量超出設定值(已先達到者為準)為止。接著,在步驟S110中,完成拉伸確認之後,對電路板10進行電性量測。例如:以探針卡對電路板10上的電性接點通電,以確 認電路板10的線路是否正常或失效。 It can be seen from the above description that when the distance that the circuit board 10 is stretched exceeds a set value, although the force for stretching the circuit board 10 does not exceed the set value, in order to prevent the circuit board 10 from being over-pull, the fixing jig 120 is pulled. Stretch the position. On the contrary, when the distance that the circuit board 10 is stretched does not exceed a set value, a greater tensile force is applied to the circuit board 10 until the circuit board 10 is stretched beyond the set value or stretched to the circuit board 10. The power exceeds the set value (whichever comes first). Next, in step S110, after the completion of the stretching confirmation, the circuit board 10 is electrically measured. For example, the probe card is used to energize the electrical contacts on the circuit board 10 to ensure Confirm that the circuit of the circuit board 10 is normal or invalid.

Problem, and avoid the problem that the board is deformed and the position is shifted due to over-pull when the board is stretched. In addition, the size of the clamp is small, and it is not necessary to exit the interference zone of the electrical tester, and the serrated chuck can relatively increase the friction of the clamped circuit board, which has the advantages of cost reduction and assembly simplification.
