DescriptionDonor wrote, "Not to be left out, manufacturers of flexible printed circuit tape began
flooding the market with super-fine-line geometries, executed on reel-to-reel
tape patterns, as shown in this collection from some 40 different
suppliers. The reel-to-reel tape assembly process for packaging chips took a
huge turn upward in the 1970s, when National Semiconductor launched its
TAB (tape automated bonding) program with 3M Corporation, in
developing a fully automated gang bonding process. Samples of this are
shown in this collection."
One sample contains a label "3M Micro interconnecting Systems". Another sample is labeled AUGAT PACTEL PRODUCTS".
