Chip attach
WebPlacement: Flip chip placement accuracy typically has tighter requirements compared to standard epoxy die attach of wire bonded devices, because the die with its bumps has to be aligned to the bond pads on the substrate. Most of the placement machines offered for flip chip applications are specified for ±9 to 12 µm at ±3σ. WebChip Scale Packaging, Stack-Chip Packaging, Through Silicon (STV) Via Filling and Underfill. AI Technology, Inc. pioneered the use of flexible die-attach film and paste adhesives for larger chip and die bonding in the early 1980s. The company has since found success in extending its adhesive line to offer the widest selection in the industry.
