Hello Technet:

 

We have an application where we have to etch a PTFE PWB in preparation
for bonding.   The etch is a commercially available sodium-containing
solution.  We're also expected to meet a water-break test prior to
bonding.  We're having trouble meeting the water-break test and was
wondering if the two (etched PWB and water-break) are compatible.  If
so, what cleaning/rinsing could be performed after the etching to ensure
a water-break free surface?

 

Thanks in advance,

 

Jim Marsico
