以下將以圖式揭露本發明之複數個實施例,為明確說明起見,許多實務上的細節將在以下敘述中一併說明。然而,應瞭解到,這些實務上的細節不應用以限制本發明。也就是說,在本發明中空體實施例中,這些實務上的細節是非必要的。此外,為簡化圖式起見,一些習知慣用的結構與元件在圖式中將以簡單示意的方式繪示之。 The embodiments of the present invention are disclosed in the following drawings, and for the purpose of illustration However, it should be understood that these practical details are not intended to limit the invention. That is to say, in the hollow body embodiment of the present invention, these practical details are not necessary.

有鑑於上述半導體封裝元件(後稱受驗元件)在測試基座上的實際溫度明顯低於檢測系統之設定溫度,導致受驗元件之試驗數據不夠精準,對此發明人經實驗後證明測試基座及受驗元件之熱能有一部分是透過連接於測試基座與測試電路板之間的探針銷之引導而朝測試電路板之方向散去,導致受驗元件與測試基座之處的實際溫度無法接近或等同檢測裝置之設定溫度。針對上述,本發明提出一具有熱阻障設計之檢測系統,可以至少減緩受驗元件與測試電路板之間的熱傳遞,進而讓受驗元件可以在預定溫度之環境中進行檢測,進而提高受驗元件於高溫檢測之試驗數據的精準度。 In view of the fact that the actual temperature of the above semiconductor package component (hereinafter referred to as the test component) on the test pedestal is significantly lower than the set temperature of the detection system, the test data of the test component is not accurate enough, and the inventor proves the test base after the experiment. The thermal energy of the seat and the tested component is partially dissipated toward the test circuit board by the guidance of the probe pin connected between the test base and the test circuit board, resulting in the actual location of the test component and the test pedestal. The temperature cannot be approximated or equivalent to the set temperature of the detection device. In view of the above, the present invention provides a detection system with a thermal barrier design that can at least slow down the heat transfer between the component under test and the test circuit board, thereby allowing the component to be inspected in a predetermined temperature environment, thereby improving the Verify the accuracy of the test data of the component at high temperature.

Fig. 2 is a partial enlarged view of a region M of Fig. 1. Fig. 3 is a partial exploded view of Fig. 2. As shown in FIG. 1 to FIG. 3 , in the present embodiment, the semiconductor package component detection system 10 includes a test circuit board 100 , a test pedestal 200 , a thermal barrier layer component 300 , and a plurality of probe pins . 400. Test board 100 has a plurality of electrical contacts 110. The electrical contacts 110 are spaced apart from one side 101 of the test circuit board 100. Test base 200 has a recess 210. The recess 210 is for receiving a semiconductor package component (for example, a semiconductor package wafer, hereinafter referred to as the test component 800). These probe pins 400 are located on the test pedestal 200 and are spaced apart within the test pedestal 200. Each probe pin 400 passes through the conduit 220 of the test base 200 such that one end of each probe pin 400 (i.e., the upper end 410 of the probe pin 400) extends into the recess 210 or at least from the bottom surface 211 of the recess 210. Upon exposure, the other end (i.e., the lower end 420 of the probe pin 400) abuts the thermal barrier element 300. The probe pin 400 includes a pogo pin, but is not limited thereto. The thermal barrier layer component 300 is located between the test circuit board 100 and the test pedestal 200, and can not only electrically connect the probe pin 400 and the electrical contact 110, but also can at least slow down the probe pin 400 and the electrical contact 110. The heat transfer between.
在本實施例中,詳細來說,熱阻障層元件300包含一絕緣墊310與多個導電隔熱部320。每個絕緣墊310位於測試電路板100與測試基座200之間。導電隔熱部320形成於絕緣墊310上,直接夾合於其中一電性接點110及其中一探針銷400之間,用以熱阻隔探針銷400與電性接點110。更具體地,絕緣墊310包含一墊體311與多個容納區312。墊體311具有相對配置之第一表面311A與第二表面311B,且第一表面311A面向測試電路板100。這些容納區312間隔地形成於墊體311內,且每個容納區312連接墊體311之第一表面311A與第二表面311B。每個導電隔熱部320一體成形地位於容納區312內。墊體311介於任二容納區312之間的區域A1分別對齊任二電性接點110之間的區域A2。 In this embodiment, in detail, the thermal barrier layer component 300 includes an insulating pad 310 and a plurality of conductive heat insulating portions 320. Each insulating pad 310 is located between the test circuit board 100 and the test pedestal 200. The conductive heat insulating portion 320 is formed on the insulating pad 310 and directly sandwiched between one of the electrical contacts 110 and one of the probe pins 400 for thermally blocking the probe pin 400 and the electrical contact 110. More specifically, the insulating mat 310 includes a pad body 311 and a plurality of receiving areas 312. The pad body 311 has a first surface 311A and a second surface 311B opposite to each other, and the first surface 311A faces the test circuit board 100. The receiving areas 312 are formed in the pad body 311 at intervals, and each of the receiving areas 312 connects the first surface 311A and the second surface 311B of the pad body 311. Each of the electrically conductive insulating portions 320 is integrally formed within the receiving area 312. The area A1 of the pad body 311 between any two receiving areas 312 is respectively aligned with the area A2 between any two electrical contacts 110.
在本實施例中,在製成熱阻障層元件300時,首先將這些已成形之導電隔熱部320分別排列於一模具內,接著,於模具內填滿絕緣墊310之液態原料,待絕緣墊310固化成型後,開模後即可得到厚度相同或不同厚度的熱阻障層元件300,其中每個導電隔熱部320填滿於容納區312內,分別與墊體311之第一表面311A與第二表面311B齊平。 In the present embodiment, when the thermal barrier layer component 300 is formed, the formed conductive thermal insulation portions 320 are first arranged in a mold, and then the liquid material of the insulating mat 310 is filled in the mold. After the insulating mat 310 is solidified and formed, the thermal barrier layer elements 300 having the same thickness or different thicknesses can be obtained after the mold is opened, wherein each of the conductive heat insulating portions 320 is filled in the receiving area 312, and is respectively first with the mat body 311. The surface 311A is flush with the second surface 311B.
如第1圖與第2圖,檢測系統10更包含一分配手臂500(handler test arm)。分配手臂500用以移動不同之受驗元件800至測試基座200,並於測試完成後移除測試基座200上之受驗元件800。如此,當分配手臂500(handler test arm)將一受驗元件800放入凹槽210內,使得受驗元件800之多個端點810(如銲球solder ball)分別一一接觸這些探針銷400之上端部410,此時,受驗元件800之每個端點810便能夠透過對應位置之探針銷400與導電隔熱部320電性連接測試電路板100之其中一電性接點110。 As in Figures 1 and 2, the detection system 10 further includes a handler test arm 500. The dispensing arm 500 is configured to move a different test component 800 to the test pedestal 200 and remove the tested component 800 on the test pedestal 200 after testing is complete. Thus, when the hand test arm 800 places an expedited component 800 into the recess 210, the plurality of end points 810 of the component 800 (such as solder ball) are contacted one by one. The upper end portion 410 of the test device 800 is electrically connected to one of the electrical contacts 110 of the test circuit board 100 through the probe pin 400 and the conductive heat insulating portion 320 of the corresponding position. .
在測試期間,由於熱阻障層元件300受夾合於測試電路板100與測試基座200之間,熱阻障層元件300能夠熱阻隔這些探針銷400與測試電路板100,或者,至少能夠減緩探針銷400與電性接點110之間的熱傳遞,故,測試基座200(包含受驗元件800)之位置所受到之熱能不致迅速透過探針銷400散去。如此,不僅降低受驗元件800的試驗數據不夠精準的機會,也確保熱能不致傷害測試電路板100。 During the test, since the thermal barrier layer component 300 is sandwiched between the test circuit board 100 and the test pedestal 200, the thermal barrier layer component 300 can thermally block the probe pins 400 from the test circuit board 100, or at least The heat transfer between the probe pin 400 and the electrical contact 110 can be slowed down, so that the thermal energy received by the test susceptor 200 (including the component 800) is not quickly dissipated through the probe pin 400. In this way, not only is the opportunity for the test data of the component 800 to be less accurate, but also the thermal energy is not damaged to the test circuit board 100.
此外,檢測系統10更包含一加熱器600與一溫度感測器700。加熱器600位於分配手臂500上,用以對測試基座 200(包含受驗元件800)加熱至預設溫度,以控制測試基座200(包含受驗元件800)之位置之環境溫度。溫度感測器700位於分配手臂500或測試基座200(圖中未示),用以感測受驗元件800的溫度。然而,若僅考慮測試電路板不致受到熱能傷害之目的,本發明不限必須具有加熱器與溫度感測器。 In addition, the detection system 10 further includes a heater 600 and a temperature sensor 700. The heater 600 is located on the dispensing arm 500 for the test base 200 (including the component 800 in question) is heated to a preset temperature to control the ambient temperature at the location of the test pedestal 200 (including the component 800 in question). Temperature sensor 700 is located in dispensing arm 500 or test pedestal 200 (not shown) for sensing the temperature of subject 800. However, the present invention is not necessarily limited to having a heater and a temperature sensor if only the test circuit board is not subjected to thermal energy damage.
第4圖繪示第1圖之熱阻障層元件300之上視圖。如第4圖所示,這些導電隔熱部320間隔地排列於絕緣墊310上,舉例來說,但不以此為限,這些導電隔熱部320以一矩陣方式排列於絕緣墊310上。然而,只要配合受驗元件800之端點810、探針銷400以及測試電路板100之電性接點110之排列方式,本發明不限於這些導電隔熱部320之排列方式。此外,絕緣墊310呈矩形,且這些導電隔熱部320呈圓形,且絕緣墊310之面積不大於測試基座200底面之面積,然而,本發明不限於絕緣墊310、導電隔熱部320之形狀以及絕緣墊310之面積。 4 is a top view of the thermal barrier layer element 300 of FIG. 1. As shown in FIG. 4, the conductive heat insulating portions 320 are spaced apart from each other on the insulating pad 310. For example, but not limited to, the conductive heat insulating portions 320 are arranged in a matrix on the insulating pad 310. However, the present invention is not limited to the arrangement of the conductive heat insulating portions 320 as long as the arrangement of the end points 810 of the test element 800, the probe pins 400, and the electrical contacts 110 of the test circuit board 100 is matched. In addition, the insulating pads 310 are rectangular, and the conductive heat insulating portions 320 are circular, and the area of the insulating pads 310 is not larger than the area of the bottom surface of the test pedestal 200. However, the present invention is not limited to the insulating pads 310 and the conductive heat insulating portion 320. The shape and the area of the insulating mat 310.
在本實施例中,導電隔熱部320之材料為奈米碳管氣凝膠,是為一種包含奈米碳管(carbon nano tube)之氣凝膠(Aerogel)。碳管氣凝膠是極輕又具有彈性的固體物質。因為其堅固的結構,使碳管氣凝膠可以支撐比其重量100倍以上的重量。碳管氣凝膠具有大量的孔洞(不大於100奈米),其孔洞分布廣,具有良好的透氣性。此外,與其他氣凝膠不同的是,由於碳管氣凝膠之奈米碳管具有鏈結性,可電連接上述任一導電隔熱部兩側之導體,故,碳管氣凝膠可同時導電,也可以能阻絕熱量轉移,以提供良好的熱阻隔能力。 In the present embodiment, the material of the conductive heat insulating portion 320 is a carbon nanotube aerogel, which is an aerogel containing a carbon nano tube. Carbon tube aerogels are extremely light and elastic solid materials. Because of its strong structure, the carbon tube aerogel can support more than 100 times its weight. Carbon tube aerogel has a large number of holes (not more than 100 nm), and its pores are widely distributed and have good gas permeability. In addition, unlike other aerogels, carbon nanotube aerogels can be electrically connected to the conductors on either side of any of the above-mentioned conductive heat insulating portions because of the chain nature of the carbon nanotube aerogel. Conductive at the same time can also block heat transfer to provide good thermal barrier.
然而,本發明不限於此,只要能同時符合導電及 隔熱(或低導熱)特性,導電隔熱部之材料亦可以為奈米碳管矽膠,亦即一種具有包含奈米碳管之矽膠。 However, the present invention is not limited thereto as long as it can simultaneously conform to conduction and Insulation (or low thermal conductivity), the material of the conductive insulation can also be a carbon nanotube rubber, that is, a silicone having a carbon nanotube.
第5圖繪示本發明一實施例之檢測系統11的局部放大圖。如第5圖所示,第5圖之熱阻障層元件301大致相同第2圖之熱阻障層元件300,相同的部件沿用相同的符號。然而,第5圖之熱阻障層元件301與第2圖之熱阻障層元件300差別在於:至少一個或每個導電隔熱部320面向探針銷400之表面具有一凹陷槽321。凹陷槽321具有一弧形底面322,弧形底面322連接墊體311之第二表面311B。探針銷400伸入凹陷槽321內,且抵靠凹陷槽321之弧形底面322。由於弧形底面322具有一特定弧度,使得伸入之探針銷400不致輕易脫離導電隔熱部320之位置,以致定位於對應導電隔熱部320,進而維持電氣傳導之性能。 FIG. 5 is a partial enlarged view of the detecting system 11 according to an embodiment of the present invention. As shown in Fig. 5, the thermal barrier layer element 301 of Fig. 5 is substantially the same as the thermal barrier layer element 300 of Fig. 2, and the same components are denoted by the same reference numerals. However, the thermal barrier layer element 301 of FIG. 5 differs from the thermal barrier layer element 300 of FIG. 2 in that at least one or each of the electrically conductive thermally insulating portions 320 has a recessed groove 321 facing the surface of the probe pin 400. The recessed groove 321 has a curved bottom surface 322, and the curved bottom surface 322 is connected to the second surface 311B of the pad body 311. The probe pin 400 extends into the recessed groove 321 and abuts against the curved bottom surface 322 of the recessed groove 321 . Since the curved bottom surface 322 has a certain curvature, the protruding probe pin 400 is not easily separated from the position of the conductive heat insulating portion 320 so as to be positioned at the corresponding conductive heat insulating portion 320, thereby maintaining the electrical conduction performance.
第6圖繪示本發明一實施例之檢測系統12的局部放大圖。如第6圖所示,第6圖之熱阻障層元件302大致相同第2圖之熱阻障層元件300,相同的部件沿用相同的符號。然而,第6圖之熱阻障層元件302與第2圖之熱阻障層元件300差別在於:絕緣墊310包含一墊體311與多個貫孔313。墊體311具有相對配置之第一表面311A與第二表面311B,第一表面311A面向測試電路板100。這些貫孔313間隔地排列於墊體311上,且每個貫孔313連接墊體311之第一表面311A與第二表面311B。每個導電隔熱部320覆蓋第一表面311A及貫孔313,使得每個探針銷400伸入對應之貫孔313內並接觸對應之導電隔熱部320。由於探針銷400可有效地被限位於貫孔313內,使得 對應之探針銷400得以接觸對應導電隔熱部320,不致輕易脫離導電隔熱部320,進而維持電氣傳導之性能。 Figure 6 is a partial enlarged view of the detection system 12 in accordance with an embodiment of the present invention. As shown in Fig. 6, the thermal barrier layer element 302 of Fig. 6 is substantially the same as the thermal barrier layer element 300 of Fig. 2, and the same components are denoted by the same reference numerals. However, the thermal barrier layer element 302 of FIG. 6 differs from the thermal barrier layer element 300 of FIG. 2 in that the insulating pad 310 includes a pad body 311 and a plurality of through holes 313. The pad body 311 has a first surface 311A and a second surface 311B opposite to each other, and the first surface 311A faces the test circuit board 100. The through holes 313 are spaced apart from each other on the pad body 311, and each of the through holes 313 is connected to the first surface 311A and the second surface 311B of the pad body 311. Each of the conductive heat insulating portions 320 covers the first surface 311A and the through holes 313 such that each of the probe pins 400 protrudes into the corresponding through hole 313 and contacts the corresponding conductive heat insulating portion 320. Since the probe pin 400 can be effectively confined within the through hole 313, The corresponding probe pin 400 is brought into contact with the corresponding conductive heat insulating portion 320 so as not to be easily separated from the conductive heat insulating portion 320, thereby maintaining electrical conduction performance.
此外,本實施例中之至少一個或每個導電隔熱部320面向貫孔313之表面也可以具有第5圖所示之凹陷槽321,以降低探針銷400於對應之導電隔熱部320上滑動的機會。 In addition, at least one or each of the conductive heat insulating portions 320 in the embodiment may have a recessed groove 321 as shown in FIG. 5 to reduce the probe pin 400 to the corresponding conductive heat insulating portion 320. The chance to slide on.
第7圖繪示本發明一實施例之檢測系統13的側視示意圖。如第7圖所示,第7圖之檢測系統13大致相同第1圖之檢測系統10,相同的部件沿用相同的符號,其差別在於:第7圖之熱阻障層元件303並非如第1圖之熱阻障層元件300位於測試電路板100與測試基座200之間,而是熱阻障層元件303位於凹槽210之底面211,且覆蓋這些探針銷400,用以電性導接探針銷400與受驗元件800,且至少減緩探針銷400與受驗元件800之間的熱傳遞。 FIG. 7 is a side elevational view of the detection system 13 in accordance with an embodiment of the present invention. As shown in Fig. 7, the detecting system 13 of Fig. 7 is substantially the same as the detecting system 10 of Fig. 1, and the same components are denoted by the same reference numerals, and the difference is that the thermal barrier layer element 303 of Fig. 7 is not the first one. The thermal barrier layer component 300 is located between the test circuit board 100 and the test pedestal 200, but the thermal barrier layer component 303 is located on the bottom surface 211 of the recess 210 and covers the probe pins 400 for electrical conduction. The probe pin 400 is coupled to the subject element 800 and at least slows heat transfer between the probe pin 400 and the subject element 800.
如此,當一受驗元件800被放入凹槽210內時,熱阻障層元件303直接位於受驗元件800與這些探針銷400之間,使得每個導電隔熱部320直接位於受驗元件800之其中一端點810以及其中一探針銷400之間,亦即,每個導電隔熱部320接觸其中一探針銷400之上端部410以及受驗元件800之其中一端點810(如銲球solder ball)。此時,由於每個探針銷400之下端部420直接接觸測試電路板100之其中一電性接點110,受驗元件800之每個端點810便能夠透過對應位置之導電隔熱部320與探針銷400電性連接測試電路板100之電性接點110。 Thus, when a component 800 is placed in the recess 210, the thermal barrier layer 303 is directly between the component 800 and the probe pins 400 such that each conductive insulator 320 is directly positioned Between one of the end points 810 of the component 800 and one of the probe pins 400, that is, each of the conductive insulating portions 320 contacts one of the upper end portions 410 of the probe pin 400 and one of the end points 810 of the tested component 800 (eg, Solder ball). At this time, since the lower end portion 420 of each probe pin 400 directly contacts one of the electrical contacts 110 of the test circuit board 100, each end point 810 of the test component 800 can pass through the conductive heat insulating portion 320 of the corresponding position. The electrical contact 110 of the test circuit board 100 is electrically connected to the probe pin 400.
在測試期間,由於熱阻障層元件303受夾合於受驗 元件800與探針銷400之間,可有效地避免測試基座200(包含受驗元件800)所受到之熱能透過這些探針銷400迅速散去,不僅降低受驗元件800的試驗數據不夠精準的機會,也確保熱能不致傷害測試電路板100。 During the test, since the thermal barrier layer element 303 is clamped to the test Between the component 800 and the probe pin 400, the thermal energy received by the test pedestal 200 (including the component to be tested 800) can be effectively prevented from being quickly dissipated through the probe pins 400, and the test data of the component 800 is not reduced accurately. The opportunity also ensures that thermal energy does not harm the test board 100.
此外,在此實施方式中,檢測系統13也配置有合適的定位機制,使得熱阻障層元件303得以固定於凹槽210內,不致隨著檢測過程而被帶起或產生位移。所述定位機制例如透過夾合或黏合方式,將熱阻障層元件303得以固定於凹槽210之底面211。然而,本發明不限於此。 Moreover, in this embodiment, the detection system 13 is also configured with a suitable positioning mechanism such that the thermal barrier layer element 303 is secured within the recess 210 so as not to be brought up or displaced as the detection process. The positioning mechanism fixes the thermal barrier layer element 303 to the bottom surface 211 of the recess 210, for example, by means of clamping or bonding. However, the invention is not limited thereto.
須了解到,本發明具有通常知識者因應任何需求與限制也可以將第7圖之熱阻障層元件303改為第2圖、第5圖與第6圖之熱阻障層元件300~302。 It should be understood that the present invention has the general knowledge that the thermal barrier layer element 303 of FIG. 7 can be changed to the thermal barrier layer elements 300-302 of FIG. 2, FIG. 5 and FIG. 6 in response to any need and limitation. .
如此,藉由以上實施例所述之檢測系統,無論熱阻障層元件介於探針銷與電性接點之間,或者介於探針銷與受驗元件之間,測試基座以及受驗元件所受到之熱能都能被確保不致迅速朝測試電路板之方向散去,不僅降低受驗元件的高溫檢測之試驗數據受到影響的機會,也確保熱能不致傷害測試電路板。 Thus, with the detection system described in the above embodiments, whether the thermal barrier layer component is interposed between the probe pin and the electrical contact, or between the probe pin and the test component, the test pedestal and the The thermal energy received by the component can be ensured that it does not quickly dissipate in the direction of the test board, which not only reduces the chance of the test data of the high temperature detection of the component being affected, but also ensures that the thermal energy does not harm the test board.
最後,上述所揭露之各實施例中,並非用以限定本發明,任何熟習此技藝者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾,皆可被保護於本發明中。因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Finally, the various embodiments disclosed above are not intended to limit the invention, and those skilled in the art can be protected in various modifications and refinements without departing from the spirit and scope of the invention. In the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
