Des: Jumpers per IPC-A-610 2/14/97
Date:
To creators/maintaining committees for IPC-A-610:
IPC-A-610, in paragraph 9.3.1.5 states that jumper wires "For Class 3 assemblies wire should meet the requirements of MIL-W-81822." However, this wire specification is exclusively for solderless wrap applications. We have found that in using it in the manner specified for adding jumper wires per IPC-A-610, soldering, that the insulation melts when subjecting it to the heat of normal soldering. Not too unexpected for a "solderless" wire! Now, admittedly, there are a large number of different insulation materials available in the various slash sheets of this specfication, but why would a solderless wrap specification be called for here which is not in every case specific for soldering? Is there a revision forthcoming that will rectify this? If not, consider this to be a vote for a correction in the next revision, since we have a contract that specifically requires IPC-A-610 and this paragraph has caused us considerable problems.
