It was discovered that there is a hardware problem with the existing VLSI DFM (fast class) board (comp level M). The new board (comp level N) solves the problem. The problem is characterized by intermittent loss or change of data along the exposed line. In some cases, the problem might appear as a shift screen or screening problem affecting the shape of the printed cell.

Replace the VLSI Board with the one supplied with the FCO kit.

Shut down the power of the Imagesetter.

Replace the old VLSI board with the new one, supplied with the FCO kit, comp level N.

* The board replacement should be implemented only with anti static protection equipment.
