A wafer prober is a machine used to test integrated circuits. For electrical testing a set of microscopic contacts or probes called a probe card are held in place whilst the wafer, vacuum-mounted on a wafer chuck, is moved into electrical contact.fter IC packaging, a packaged chip will be tested again during the IC testing phase, usually with the same or very similar test patterns. For this reason, one might think that wafer testing is an unnecessary, redundant step.
Shalom (Hebrew: ×©Ö¸×××Ö¹× shalom; also spelled as sholom, sholem, sholoim, shulem) is a Hebrew word meaning peace, harmony, wholeness, completeness, prosperity, welfare and tranquility and can be used idiomatically to mean both hello and goodbye.
The Hebrew predominantly uses three words, but one we will not consider because it refers to the peace offering. The second is charash. It means to hold one's peace, quiet, silent, rest, and a host of nuances both positive and negative depending on the context. The third is the very familiar greeting, shalom.
