[NJARC] Conductive epoxy

[Jim Whartenby]

DaveIf you just want to repair a break and silver is not really a necessity, eBay has several carbon and nickel paint pens that are under $15 each.  I think that all of these vendors are stateside.  There is also one vendor who sells 0.2 ml silver loaded paint for under $2 which might be a good solution, item # 113388292356 but the vendor is in Hong Kong so you are looking at a few weeks travel time.
When I was a production engineer at Microwave Semiconductor Corporation too many years ago, the production amplifiers were tuned by either cutting microstrip with an Exacto knife or dabbing on silver paint to widen the microstrip line.  There was no need for epoxy since the paint was dry is a few minutes and was quite durable.
Hope this helps and here is wish for a prosperous new year to one and all,Jim
I wonder why people argue over the 10% of their differences and ignore the 90% they agree on?

 Need literally a drop, a 'dollop', so was hoping to avoid having to purchase a whole container. (Open focus pot on CT-100.)

Hi Dave,

Check Amazon/E-bay for "silver filled epoxy."   It's expensive due to 
the precious-metal content.  There are a lot of variables, e.g. working 
time, and curing temperature.
