    摘要: A cyclic reduced Gray code in n-many bits having 2k-many entries, for any natural number k, where 2(n−1)

    摘要翻译: 对于任意自然数k,在n个许多位中具有2k个条目的循环缩小格雷码,其中2(n-1)<2K <2 和n 是通过首先用反射的二进制技术在n多个位中构造一个二进制码,然后在上半部分中选择最后的k个有序条目来找到正整数 全反映的二进制代码,后面是完整反映的二进制代码的后半部分的第一个k个有序条目。 这些有序的2k个条目是n个位中缩短的循环缩小格雷码。 或者,可以选择全反射二进制代码的前半部分中的第一k个有序条目,随后是完全反映的二进制代码的后半部分中的最后k个有序条目。 如果原始格式或格雷码的格式被表示为列,其列是位位置,并且其行是代码条目,那么在2k多次选择之前或之后,整列可以随意交替,以产生额外的不同 循环减少的格雷码不会显示为“反射”。

    摘要: A contact structure for establishing electrical connection with contact targets. The contact structure is formed of a contactor carrier and a plurality of contactors attached to a contactor carrier. The contactors are inserted in diagonal through holes on the contactor carrier and attached to the contactor carrier through adhesives. The contactor has a top end having a flat top surface, a straight diagonal beam integral with the top end and configured by an upper beam portion and a lower beam portion, and a lower end at an end of the lower beam portion to contact with a contact target. A length of the upper beam portion and a length of the lower beam portion are about the same. A probe contact assembly using the contact structure is also disclosed which incorporates a flip chip bonding technology to interconnect the components therein.

    摘要: A probe contact system is capable of adjusting distances between tips of the contactors and contact targets with simple and low cost mechanism. The probe contact system includes a contact substrate having a large number of contactors, a probe card for fixedly mounting the contact substrate for establishing electrical communication between the contactors and a test system, a stiffener made of rigid material for fixedly mounting and reinforcing the probe card, a probe card ring attached to a frame of the probe contact system for mechanically coupling the probe card to the frame, and a plurality of adjustment members for up/down moving the stiffener relative to the probe card ring at three or more locations so that a gap between the probe card and the probe card ring can be altered.
