Production Notes

crystalfontz.com/showthread.php?p=26654&posted=1#post26654">Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost. The TAB style connection requires no separate connector, so the cost is very low, and the ultra-thin profile of the display is maintained.
