Description
本發明係關於一種半導體元件測試機台,尤其是一種具有單一貫穿輸送梭車之半導體元件測試機台。The present invention relates to a semiconductor component testing machine, and more particularly to a semiconductor component testing machine having a single through conveying shuttle.
目前測試半導體元件的方法,主要可以分為虛擬測試與實境測試,其中虛擬測試是指針對各IC的不同特性、根據預定的電路設計撰寫出特定的測試軟體,藉以確認例如腳位間是否非預期地短路或斷路、以及是否符合預定的邏輯關係;實境測試則是藉由已經具有完整功效的公板,僅將待測IC位置留白,將每個待測IC輪流補入該空白位置,測試此時公板是否能正常運作,從而確認此待測IC的功能正常,並依測試結果作為分類的依據。當要測試不同IC時,僅需替換不同公板及測試的軟體即可。At present, the methods for testing semiconductor components can be mainly divided into virtual testing and real-world testing, wherein the virtual testing is to write a specific test software according to different characteristics of each IC according to a predetermined circuit design, thereby confirming, for example, whether the feet are not between. Expected short circuit or open circuit, and whether it meets the predetermined logical relationship; the reality test is to blank the IC to be tested by the public board that has already completed the function, and fill each blank to be tested into the blank position. At this time, it is tested whether the public board can operate normally, thereby confirming that the function of the IC to be tested is normal, and the test result is used as a basis for classification. When testing different ICs, you only need to replace the different public boards and tested software.
為提昇效率,目前測試機台輸送及量測待測半導體元件過程均已採自動化測試,如圖1所示,在入料區疊放有多組入料匣4,每一入料匣4中放置有多顆待測半導體元件。開始測試時,先將最下方的入料匣4向圖式下方移出約一行的間距,並由一個入料臂31將此入料匣4第一行內的待測半導體元件5移載至橫向移動的入料梭車33上,入料梭車33隨即右移至測試臂組件221 可汲取的位置,再由測試臂組件221 將待測半導體元件5移載於測試座21進行測試。In order to improve efficiency, the current test machine has been automated and tested for the process of measuring and measuring the semiconductor components to be tested. As shown in Figure 1, multiple sets of feeds 匣4 are stacked in the feed zone, and each feed 匣4 There are a plurality of semiconductor components to be tested. When starting the test, the lowermost feed 匣4 is first removed from the lower side of the drawing by about one row, and the input semiconductor arm 5 transfers the semiconductor component 5 to be tested in the first row of the feed hopper 4 to the lateral direction. On the moving feeder shuttle 33, the incoming shuttle 33 is then moved right to the position where the test arm assembly 22 1 can be taken, and the semiconductor component 5 to be tested is transferred by the test arm assembly 22 1 to the test stand 21 for testing.
測試完成後,測試臂組件221 將已測半導體元件6送至圖式上方的出料梭車34上,出料梭車34隨即右移至出料臂32可汲取的位置,並由出料臂32依測試的數據資料做為已測半導體元件6的分類依據,分別移載至圖式右下方諸多分類料匣中的對應分類料匣中。而在前一顆半導體元件受測時,入料臂31已將次一待測半導體元件5置放於入料梭車33,並移動至右側的另一測試臂組件222 可汲取位置。因此,在左側測試臂組件221 將完測半導體元件移出測試座21時,右側測試臂組件222 可儘速將下一顆待測半導體元件5送進測試座21,繼續進行下一輪測試。After the test is completed, the test arm assembly 22 1 feeds the tested semiconductor component 6 to the discharge shuttle 34 above the drawing, and the discharge shuttle 34 is then moved right to the position where the discharge arm 32 can be taken, and discharged. The arm 32 is used as the classification basis of the tested semiconductor component 6 according to the test data, and is respectively transferred to the corresponding classification material in the plurality of classification materials at the lower right of the figure. When the previous semiconductor component is being tested, the input arm 31 has placed the next semiconductor component to be tested 5 on the input shuttle 33 and moved to the other test arm assembly 22 2 on the right to pick up the position. Therefore, when the left test arm assembly 22 1 moves the finished semiconductor component out of the test socket 21, the right test arm assembly 22 2 can feed the next semiconductor component under test 5 into the test socket 21 as soon as possible, and continue the next round of testing.
然而,當半導體元件移載時,左側測試臂組件221 與右側測試臂組件222 的移動需要彼此高度配合,使得機台本身的製造成本因而居高不下;且交接過程更需要與入料臂及出料臂移動速度彼此侷限:入料-測試-出料等三個步驟中,速度最慢的步驟將限制整體產出效率,而往返交接過程中,對於速度較快者會浪費些許的閒置等待時間。尤其移載路徑如圖1所示,入料臂僅需在左側的入料區與緊鄰的入料梭車間移動,而出料臂則需在出料梭車與圖式右下方的分類料匣間移動,使得出料臂移動路徑遠長於入料臂移動路徑,迫使整體循環配合的同步動作並不完美;一旦半導體元件在測試座上受檢測的時間再縮短,則上述同步化不完美的些許時間浪費在整體循環中所佔比例愈高、隨之拖慢產出效率的問題益形明顯,尤其進行大量的半導體元件測試時,產出效率將明確受到侷限。再加上測試臂組件係以二維移動方式進行半導體元件測試,結構較複雜,維修上也較麻煩,使得造價及維修成本相對偏高,在自動化測試流程中,無疑是可以進一步改良的標的。However, when the semiconductor component is transferred, the movement of the left test arm assembly 22 1 and the right test arm assembly 22 2 needs to be highly matched with each other, so that the manufacturing cost of the machine itself is thus high; and the handover process is more required with the input arm. And the movement speed of the discharge arm is limited to each other: in the three steps of feeding-testing-discharging, the slowest step will limit the overall output efficiency, and in the round-trip handover process, a little idle will be wasted for the faster one. waiting time. In particular, as shown in Figure 1, the feed arm only needs to be moved in the loading zone on the left side and the incoming feed shuttle shop, while the discharge arm needs to be in the sorting material at the bottom right of the shuttle and the bottom of the drawing. The movement between the discharge arms is much longer than the movement path of the feed arm, forcing the synchronous action of the overall cycle fit to be imperfect; once the time for the semiconductor component to be tested on the test socket is shortened, the above synchronization is not perfect. The higher the proportion of time wasted in the overall cycle, and the slower the output efficiency, the more obvious the benefits. In particular, when a large number of semiconductor components are tested, the output efficiency will be clearly limited. In addition, the test arm assembly performs semiconductor component testing in a two-dimensional movement manner, the structure is complicated, and the maintenance is troublesome, so that the cost and maintenance cost are relatively high, and in the automated test process, it is undoubtedly a standard that can be further improved.
因此,若能提供一種各傳輸機械臂均以一維方式移動而移載半導體元件、且能加快移載速度、以及簡化結構、降低成本的測試機台,使移載速度能提高至配合測試速度,不僅能夠降低測試時的閒置時間,而簡化的測試機台在造價上及維修上也相對的便宜,而且損壞的機率較低,使得自動化測試流程更不容易被迫中斷,達到降低成本的同時亦能夠更有效率的測試半導體元件的目的。Therefore, it is possible to provide a test machine in which each transfer robot arm moves in one-dimensional manner to transfer semiconductor components, and can speed up the transfer speed, and simplifies the structure and reduces the cost, so that the transfer speed can be improved to match the test speed. Not only can it reduce the idle time during testing, but the simplified test machine is relatively cheap in terms of cost and maintenance, and the probability of damage is low, making the automated test process less likely to be interrupted, reducing costs. It is also possible to test semiconductor components more efficiently.

The feeding carrier is driven through the conveying shuttle so that the feeding carrier corresponds to the test arm assembly, and at the same time, the discharging carrier corresponds to the discharging arm, and the feeding carrier is used by the testing arm assembly.

Therefore, when the test arm assembly is similarly transferred to the next batch of semiconductor components to be tested, the discharge arm similarly transfers the tested semiconductor components, and the transfer operation is performed through sequential switching. It can be synchronized with the test operation to achieve all of the above purposes.
有關本發明之前述及其他技術內容、特點與功效,在以下配合參考圖式之較佳實施例的詳細說明中,將可清楚的呈現。The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt;
請一併參考圖2及圖3所示,為本案具有單一貫穿輸送梭車之半導體元件測試機台之第一較佳實施例,主要包括基座1’、測試裝置2’及輸送裝置3’,其中基座1’上形成有一個供擺放料匣的入料區11’及出料區12’,入料區11’處的料匣內,預先承載放置有複數個待測半導體元件5,而出料區12’則是分別供置放複數個料匣,每個料匣分別對應承載具有某特定電氣性質、且被測試分類完畢的半導體元件,為便於說明,在此定義位於入料區11’的料匣為入料匣4’,且在本例中,入料匣4’是以堆疊方式置放於入料區11’,而位於出料區12’的多個料匣為分類料匣7’。Please refer to FIG. 2 and FIG. 3 together, which is a first preferred embodiment of a semiconductor component testing machine having a single through-feeding shuttle, which mainly includes a base 1', a testing device 2' and a conveying device 3'. The susceptor 1' is formed with a feeding area 11' for discharging the hopper and a discharging area 12'. The plurality of semiconductor elements to be tested are pre-loaded in the material hopper at the feeding area 11'. And the discharge area 12' is separately for placing a plurality of materials, each material corresponding to a semiconductor component having a certain electrical property and being tested and classified, for convenience of explanation, the definition is located here. The material of the zone 11' is the feed 匣 4', and in this example, the feed 匣 4' is placed in the feed zone 11' in a stacked manner, and the plurality of feeds located in the discharge zone 12' are Category 匣7'.
設置在基座1’上的測試裝置2’在本例中包括一個測試座21’及一個對應的測試臂組件22’,測試臂組件22’則例釋為一個附有吸嘴220’及溫度調節件222’的機械臂221’,藉由吸嘴220’施加負壓吸引/釋放負壓方式汲取/釋放待測半導體元件5,溫度調節件222’則可依照需求進行溫度調節,尤其在進行半導體元件測試時,保持待測半導體元件5處於一個預定溫度,以測試出半導體元在模擬出的高溫環境或是低溫環境狀態下是否還能正常運作。機械臂221’則將吸嘴220’所汲取的待測半導體元件5移入測試座21’或反向移出。雖然在本例中係使用吸嘴以負壓/釋放負壓方式汲取半導體元件,但熟悉本技術者亦可使用例如夾持等方式進行移載,皆無礙於本案之實施。The test device 2' disposed on the base 1' includes a test stand 21' and a corresponding test arm assembly 22' in this example. The test arm assembly 22' is illustrated as having a nozzle 220' attached thereto and a temperature. The mechanical arm 221' of the adjusting member 222' extracts/releases the semiconductor component 5 to be tested by applying a vacuum suction/release negative pressure by the suction nozzle 220', and the temperature adjusting member 222' can perform temperature adjustment according to requirements, especially in progress. During the testing of the semiconductor component, the semiconductor component 5 to be tested is kept at a predetermined temperature to test whether the semiconductor cell can operate normally under the simulated high temperature environment or low temperature environment. The robot arm 221' moves the semiconductor component 5 to be tested drawn by the nozzle 220' into the test holder 21' or moves it in the reverse direction. Although in this example, the semiconductor element is taken by the negative pressure/release negative pressure method using a nozzle, those skilled in the art can also perform the transfer using, for example, clamping or the like, without hindering the implementation of the present invention.
輸送裝置3’則包括設置在機台上的入料臂31’、出料臂32’及貫穿輸送梭車33’。其中,入料臂31’及出料臂32’分別例釋為具有一個組吸引/釋放半導體元件的吸嘴310’、320’。同樣地,此處將入料臂31’從入料匣4’汲取待測半導體元件5的位置稱為汲取位置,釋放待測半導體元件5至貫穿輸送梭車33’上的位置定義為入料位置;而上述機械臂221’從貫穿輸送梭車33’汲取、或釋放半導體元件的位置為交換位置;出料臂32’由貫穿輸送梭車33’上取出完測半導體元件的位置則定義為出料位置,釋放至分類料匣7’之位置則為釋放位置。因此,貫穿輸送梭車33’在機台上的移動途徑係貫穿上述入料位置、交換位置、及出料位置並往返移動;並且藉由單一的貫穿輸送梭車進行輸送載運,簡化整體結構、有效降低製造成本。The conveyor 3' includes a feed arm 31', a discharge arm 32', and a through shuttle 33' disposed on the machine table. Here, the feed arm 31' and the discharge arm 32' are respectively illustrated as suction nozzles 310', 320' having a group of attracting/releasing semiconductor elements. Similarly, the position at which the feeding arm 31' draws the semiconductor component 5 to be tested from the loading port 4' is referred to as a drawing position, and the position at which the semiconductor element 5 to be tested is released to the through-feeding shuttle 33' is defined as a feeding. Position; and the position of the mechanical arm 221' from the through shuttle 33', or the release of the semiconductor component is the exchange position; the position of the discharge arm 32' from the through-feed shuttle 33' to take out the semiconductor component is defined as At the discharge position, the position released to the sorting material 匣 7' is the release position. Therefore, the movement path of the shuttle shuttle 33' on the machine platform runs through the above-mentioned feeding position, exchange position, and discharge position, and moves back and forth; and is transported and carried by a single through-feed shuttle to simplify the overall structure, Effectively reduce manufacturing costs.
且在本例中,貫穿輸送梭車33’包括兩個彼此分隔一段預定距離的承載座,分別為入料承載座331’及出料承載座332’,供分別放置待測半導體元件與完測半導體元件;入料承載座331’與出料承載座332’的間距,恰使得當入料承載座331’位於入料位置時,出料承載座332’位在交換位置;而當入料承載座331’抵達交換位置時,出料承載座332’抵達出料位置。And in this example, the through shuttle 33' includes two carriers spaced apart from each other by a predetermined distance, respectively, a loading carrier 331' and a discharge carrier 332' for respectively placing the semiconductor component to be tested and completing the measurement. The semiconductor component; the spacing between the loading carrier 331' and the discharge carrier 332' is such that when the loading carrier 331' is in the feeding position, the discharging carrier 332' is in the exchange position; When the seat 331' arrives at the exchange position, the discharge carrier 332' arrives at the discharge position.
為提供工作人員作業方便,本案之檢測機台入料區11’及出料區12’在機台上位置係位於圖2下方的側邊,並於相對的上方側邊設置測試座21’,而貫穿輸送梭車33’則橫貫圖式的機台中央部份,使得測試座21’相對於入料區11’及出料區12’,分別位在貫穿輸送梭車33’的兩相對側邊;因此,工作人員可於同一側邊位置完成上、下料。In order to provide convenient operation for the staff, the detection machine feeding area 11' and the discharging area 12' of the present case are located on the side of the machine platform at the lower side of FIG. 2, and the test seat 21' is disposed on the opposite upper side. The through-feed shuttle 33' traverses the central portion of the machine table, so that the test seat 21' is located on opposite sides of the transport shuttle 33' with respect to the feeding area 11' and the discharge area 12', respectively. Therefore, the staff can complete the loading and unloading at the same side position.
在進行移載測試作業時,一併參考圖4至圖6所示,首先如圖4所示由入料臂31’至汲取位置,從入料匣4’中透過吸嘴310’汲取待測半導體元件5,並移載至入料位置釋放,令待測半導體元件5被放置在貫穿輸送梭車33’的入料承載座331’上;同時,出料承載座332’正在交換位置接受機械臂221’所釋放的完測半導體元件。When performing the transfer test operation, referring to FIG. 4 to FIG. 6 together, first, as shown in FIG. 4, the feed arm 31' is taken to the pick-up position, and the suction nozzle 310' is taken from the feed port 4' to be tested. The semiconductor component 5 is transferred to the feeding position for release, so that the semiconductor component 5 to be tested is placed on the feeding carrier 331' of the conveying shuttle 33'; meanwhile, the discharging carrier 332' is in the exchange position receiving mechanism. The semiconductor component is completed by the arm 221'.
隨後如圖5所示,當貫穿輸送梭車33’受驅動右移,使入料承載座331’對應移至交換位置,而對應於交換位置的機械臂221’則將入料承載座331’上所承載的待測半導體元件5由吸嘴220’汲取;相對地,出料臂32’同時吸取出料承載座332’上的完測半導體元件。Then, as shown in FIG. 5, when the through shuttle 33' is driven to the right, the loading carrier 331' is correspondingly moved to the exchange position, and the robot arm 221' corresponding to the exchange position will be the loading carrier 331'. The semiconductor component 5 to be tested carried on is sucked by the suction nozzle 220'; oppositely, the discharge arm 32' simultaneously sucks the finished semiconductor component on the material carrier 332'.
再如圖6所示,當待測半導體元件5被移載至測試位置後,機械臂221’將下降,使得被吸嘴220’汲取的待測半導體元件5被壓制在測試座21’上進行測試,並同時摸擬特定環境,由溫度調節件222’調整施加預定溫度至待測半導體元件5,並將測試結果傳輸至處理分類裝置23’。此過程中,出料臂32’已經依照處理分類裝置23’的指令,將所汲取的完測半導體元件釋放至對應的分類料匣7’中。而在進行測試的同時,貫穿輸送梭車33’亦會被驅動左移回復至原來位置,使入料承載座331’對應至入料位置,而出料承載座332’則對應至交換位置,準備承接下一輪半導體元件,進行下一循環運作。As shown in FIG. 6, after the semiconductor component 5 to be tested is transferred to the test position, the robot arm 221' will be lowered, so that the semiconductor component 5 to be tested captured by the nozzle 220' is pressed on the test socket 21'. The test is performed while simulating a specific environment, and the temperature adjustment member 222' adjusts the application of the predetermined temperature to the semiconductor element 5 to be tested, and transmits the test result to the process sorting means 23'. In this process, the discharge arm 32' has released the captured semiconductor component to the corresponding sorting magazine 7' in accordance with the instruction of the processing sorting means 23'. While the test is being carried out, the through shuttle 33' will also be driven to the left to return to the original position, so that the loading carrier 331' corresponds to the feeding position, and the discharging carrier 332' corresponds to the exchange position. Prepare to take over the next round of semiconductor components for the next cycle of operation.
由於,貫穿輸送梭車33’可以一肩承擔入料與出料的雙重責任,並且入料臂入料時間恰為測試臂組件出料時間,而測試臂組件入料又恰可供出料臂出料,此種設計讓貫穿輸送梭車一舉統合入料與出料的同步協調運作,使得入、出料動作可以被高度同步化,移載作業與測試作業效率從而提昇,機台之競爭力與市場接受度藉此提高,達成本發明所有上述目的。Because the through shuttle 33' can shoulder the dual responsibility of feeding and discharging, and the feeding arm feeding time is just the test arm assembly discharging time, and the test arm assembly feeding is ready for the discharging arm. Material, this design allows the conveyor shuttle to integrate the feeding and discharging in a synchronized manner, so that the incoming and outgoing movements can be highly synchronized, and the efficiency of the transfer operation and test operation is improved, and the competitiveness of the machine is improved. The market acceptance is thereby increased to achieve all of the above objects of the present invention.
當然,如熟於此技術領域者所能輕易理解,若測試過程耗時較長,則相較之下移載時間較短,貫穿輸送梭車勢必需停頓等待。為解決此類問題,提升整體產出效率,請參考圖7至11本案之第二較佳實施例所示,係以兩組共四個測試座21”、及兩組左、右測試臂組件221 ”、222 ”進行半導體元件的測試作業,其中測試臂組件221 ”、222 ”各別具有一個機械臂2211 ”、2212 ”;當然,本例的貫穿輸送梭車33”也同樣包括兩個入料承載座331”及兩個出料承載座332”,供同時承載兩個半導體元件;且入料臂31”、出料臂32”與機械臂2211 ”、2212 ”皆分別具有兩個吸嘴,供同時汲取與釋放兩個半導體元件。由於本例中具有兩組彼此左右平行配置的測試臂組件,因此無論入料位置、交換位置、與出料位置都必須隨之有稍微錯開的左右因應位置。Of course, as is well understood by those skilled in the art, if the test process takes a long time, the transfer time is relatively short, and it is necessary to wait for the shuttle to pass through. In order to solve such problems and improve the overall output efficiency, please refer to the second preferred embodiment of the present invention shown in FIGS. 7 to 11, in which two sets of four test seats 21" and two sets of left and right test arm assemblies are used. 22 1 ”, 22 2 ” performs a test operation of the semiconductor component, wherein the test arm assemblies 22 1 ′′, 22 2 ′′ each have a mechanical arm 221 1 ”, 221 2 ”; of course, the transport shuttle 33 of this example feeding also includes two supporting base 331 'and two discharge supporting base 332 ", while the carrier for the two semiconductor elements; and the feeding arm 31', the feed arm 32" and the robot arm 2211 ', 2212 Each has two nozzles for simultaneously capturing and releasing two semiconductor components. Since there are two sets of test arm assemblies arranged in parallel to each other in the present example, there must be a slightly offset left and right corresponding position regardless of the feeding position, the exchange position, and the discharge position.
如圖7所示,當貫穿輸送梭車33”位於圖式左側位置時,入料承載座331”對應於偏左入料位置,此時入料臂31”一次將兩個待測半導體元件5置放於入料承載座331”中,且出料承載座332”位於對應於左側測試臂組件221 ”的偏左交換位置,接收其完測半導體元件。隨後如圖8所示,貫穿輸送梭車33”受到驅動而右移,使入料承載座331”對應於左側測試臂組件221 ”的偏左交換位置,由機械臂2211 ”汲取位於入料承載座331”內的兩個待測半導體元件5;同時,出料臂32”也由位於偏左出料位置處的出料承載座332”中,取出兩個已測半導體元件6加以分類,完成一次循環的上半程。As shown in FIG. 7, when the through-feed shuttle 33" is located at the left side of the drawing, the loading carrier 331" corresponds to the left-hand feeding position, at which time the feeding arm 31" will have two semiconductor elements 5 to be tested at a time. Placed in the feed carrier 331", and the discharge carrier 332" is located at a left-hand exchange position corresponding to the left test arm assembly 22 1 ", receiving its finished semiconductor component. Then 8, 33 through the transport shuttle car "is driven to the right, so that the supporting base material 331" corresponds to the left arm assembly 221 test "left switching position, by a robot arm 2211 'is located in the draw Two semiconductor elements to be tested 5 in the material carrier 331"; at the same time, the discharge arm 32" is also in the discharge carrier 332" located at the left discharge position, and the two tested semiconductor components 6 are taken out for classification. , complete the first half of a cycle.
接著如圖9所示,入料承載座331”再受到驅動向左移動,進行本循環的下半程;為因應右側測試臂組件222 ”的完測時段,出料承載座332”此時是回到右側交換位置,使得入料承載座331”同步回復右側入料位置,再次承接由入料臂31”所釋放的下一批(兩個)待測半導體元件5,同時測試臂組件222 ”則將兩個已測半導體元件6由機械臂2212 ”釋放至兩個出料承載座332”;此時,機械臂2211 ”則將前一步驟中所汲取的待測半導體元件5分別壓制在所屬的兩個測試座21”上,並將測試結果傳至處理分類裝置23”。Next, as shown in FIG. 9, the loading carrier 331" is further driven to the left to perform the lower half of the cycle; in response to the completion period of the right test arm assembly 22 2 ", the discharge carrier 332" is now It is returned to the right exchange position, so that the feeding carrier 331" synchronously returns to the right feeding position, and again receives the next batch (two) of semiconductor elements to be tested 5 released by the feeding arm 31", while testing the arm assembly 22 2 "then the two semiconductor elements have been measured by the robot arm 221 6 2" to release the two supporting base material 332 "; in this case, the robot arm 2211 'of the semiconductor device to be tested in the previous step will be drawn 5 They are respectively pressed on the two test stands 21" to which they belong, and the test results are transmitted to the process sorting device 23".
故如圖10所示,當機械臂2211 ”與測試座21”持續進行測試過程中,入料承載座331”將再度右移至偏右交換位置,供機械臂2212 ”的吸嘴汲取,且出料承載座332”也右移至偏右出料位置,供出料臂32”汲取完測半導體元件,再度依照處理分類裝置23”指示分類至適當的分類料匣中。Therefore, as shown in FIG. 10, during the continuous test of the robot arm 221 1 ′′ and the test seat 21 ′′, the feeding carrier 331 ′ will be moved right again to the right exchange position for the suction of the robot arm 22 2 ′′. And the discharge carrier 332" is also moved right to the right discharge position, and the discharge arm 32" takes the semiconductor component and takes it into the appropriate classification according to the processing classification device 23" indication.
最後如圖11所示,貫穿輸送梭車回復到左側,使入料承載座331”對應於偏左入料位置,再度接納由入料臂31”送來的下一批待測半導體元件5,機械臂2211 ”則將已測試完畢的完測半導體元件6移載至偏左交換位置的出料承載座332”上,機械臂2212 ”則持續將所汲取的待測半導體元件5移至所屬的測試位置並壓制在測試座21”上,並將測試結果傳至處理分類裝置23”,從而完成整個循環。Finally, as shown in FIG. 11, the shuttle shuttle is returned to the left side so that the loading carrier 331" corresponds to the left-side feeding position, and the next batch of semiconductor components to be tested 5 fed by the loading arm 31" is again received. The robot arm 221 1 ′′ transfers the tested semiconductor component 6 to the discharge carrier 332 ′′ of the left-side exchange position, and the robot 221 2 ′′ continuously moves the captured semiconductor component 5 to be tested to The associated test position is pressed onto the test stand 21" and the test result is passed to the process sorting device 23" to complete the entire cycle.
