1.5 DLPLCRDC4422EVM, DLPDLCR470TEVM and DLPDLCR660TEVM EVM Flex Cable

Electrical malfunctions can occur by stressing the flex cable(s) connecting the DMD circuit board to the DLPLCRDC4422EVM controller circuit board. Stressing the flex cable can be caused by:

  • Bending the cable outside the area identified in Figure 1-5 (within 20.3 mm of connector plate centers).
  • Repeatedly bending the flex cable(s) where the bend radius is less than 25.4 mm.
  • A single bending of the flex cable(s) where the bend radius is less than 6.35 mm.

NOTE

The minimum bend radius for forming flex cable (flexible) circuit is 6.35 mm

Minimize any handline/movement on the flex cables during operation

Use caution when bending the flex cable to not exceed bending guidelines explained above.
