Chip probe yield
WebYield loss is due to flux residue contamination of the probe needle. The flux forms a barrier between the needle and bump, preventing electrical contact. ... The traditional process for flip chip test has been to clean the probe card or purchase a card that cost 5 to 10x more than required for the job. By taking the strategy of cleaning the ...

It's either manual or automatic test equipment. 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. When a die (or array of dice) have been electrically tested t…
