WebThe flip-chip method must be chosen according to the constraints of the final products/applications. The size and pitch of the bumps are key parameters. To get a good FPA, the flip-chip assembly must be accurate and the bonder must flexible to run all these different techniques on the same platform, from R&D to production purposes. WebDescription. Flip-chip is an interconnect scheme, providing connections from one die to another die or a die to a board. It was initially developed in the 1960s. It is also known as controlled collapse chip connection, or C4. In flip-chip interconnects, many tiny copper bumps are formed on top of a chip. The device is then flipped and mounted ...
