    • A test structure tests an electronic card having electrical contacts on one face and a chip on the other face. By way of example, the electrical contacts on the card comprise an array of solder balls. The structure comprises a socket for receiving the card such that the electrical contacts of the card face electrical contacts within the socket. The structure further comprises a plate, received over the socket and having at least two ribs which protrude downwardly from one face of the plate and are positioned over the socket to engage a center portion of the chip when the card is received in the socket. The plate also has at least two holes. One of the ribs is positioned between the two holes but does not surround either of the holes. Consequently, forced air can flow downwardly through the holes in the plate, horizontally between the plate and the chip and out of the test structure. Preferably, the two ribs cross each other, and there are four holes in the plate which are arranged in four respective quadrants defined by the cross.
    • 测试结构测试在一个面上具有电触点和另一个面上的芯片的电子卡。 作为示例,卡上的电触点包括焊球阵列。 该结构包括用于接收卡的插座,使得卡的电触点在插座内电接触。 该结构还包括一个板,容纳在该插座上,并且具有至少两个从板的一个表面向下突出的肋,并且当卡被接纳在插座中时位于插座上方以接合芯片的中心部分。 该板还具有至少两个孔。 其中一个肋位于两个孔之间,但不围绕任何一个孔。 因此,强制空气可以通过板中的孔向下流动,在板和芯片之间水平地离开测试结构。 优选地,两个肋彼此交叉,并且板中有四个孔布置在由十字架限定的四个相应的象限中。
