Hi Ramon, Several answers to your questions :-) The wire will be cable tied to other wires not just hanging in the air. The unit that the wires are in will be exposed to vibration. It is not close to the board or staked. The wire is 3" long and terminates to another wire using a solder sleeve. I agree that tinned wire is stiff but I don't know that I'd call it brittle. The reason we are so concerned about this is that the wires are coming out of a potted module that has a long lead time and is quite expensive. Like I said previously, the wire will be formed once and tied in with additional wires. I like Werner's idea better but then I'm the manufacturing guy and not the quality person ;-) Thanks, KennyB -----Original Message----- From: Dehoyos, Ramon [mailto:[log in to unmask]] Sent: Tuesday, June 07, 2005 5:46 AM To: TechNet E-Mail Forum; Bloomquist, Ken Subject: RE: [TN] Solder Wicking Importance: High Hi Ken: Several questions have to be answered: Is the wire up in the air? Is it going to be exposed to vibrations? Is it closed to the board and staked? Tinned wire is stiff and brittle. If wire is expensive and the first two questions are answered negative and the last positive I would use the wire. ( in the final application ) Regards, Ramon -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Bloomquist, Ken Sent: Monday, June 06, 2005 5:15 PM To: [log in to unmask] Subject: [TN] Solder Wicking We need a little help interpreting IPC-A-610 and thought this austere group would be the place to go. We have some wires that were tinned WAY up under the insulation. While this is not a desirable situation we want to know if they are usable. IPC-A-610 says "Acceptable: Solder wicks up wire provided the solder does not extend to a portion of the wire that is required to remain flexible." In our application the wire will be bent once during assembly and then the unit buttoned up and no more flexing will happen. Does the statement "to remain flexible" mean in the final application or during assembly? Thanks in advance for all your wisdom!
