What's the non-adhesive lined Sleeving and Boots inspection criteria in PC/WHMA-A-620?
Sleeving and boots are common in cable assembly manufacturing, it's a good way to protect the cable and connector and their joint area. For Top-cable, we always follow IPC/WHMA-A-620 standard if the connector manufacture or customer don't define the criteria.
Criteria applies to both adhesive and non-adhesive lined boots.
Target - Class 1,2,3
• Boot (A) is securely shrunk on the rear of connector adapter (crimp ring area).
• Boot does not cover threaded adapter ring (B).
• Boot overlap (C) of cable sleeving or jacket is at least three cable diameters in length to prevent exposed wires or braid when flexed.
• Boot overlap does not interfere with operation of locking ring (D)
Acceptable - Class 1,2,3
• Boot is shrunk over threaded adapter ring.
• Boot does not interfere with locking ring.
Defect - Class 1,2,3
• Boot interferes with locking ring.
Defect - Class 2,3
• Boot overlap of cable sleeving or jacket is insufficient to prevent exposure of wires or braid when flexed.
