Peter,

Did some work recently on large BNC connectors, the trouble with them is
that the body of the connector acts as a great heat sink thus drawing heat
away from the solder land and connector lead I was trying to solder.

P.s when I contacted the component supplier's they informed me that the
component in question was not suitable for wave solder. We now solder them
with an RF soldering iron.

Hope this is of some use.

Steve.

Subject: [TN] Solder spikes and icicling


Hello,

Can someone explain what are possible causes for wave
soldering spikes and icicling on the assemblies?

I am encountering this defect on boards with larger
BNC connectors and fuse jumpers. Could this be a
pre-heating issue? How would one resolve this?


Rgds,
Peter
