[Elecraft] Bad KPA100 PCB?

[Keith Regli]

 I had a similar experience with my recently completed K2/100.  The KPA100
board was the only one with the issue.  It seemed to me that very few of the
components were very delicate, so I increased the heat of the iron a bit and
was able to get the pads to accept solder.  Just be careful on the few
delicate components.  In the end everything worked out fine.

Hello!

I am just in the process of building my KPA100. And I discover more and more
solder points on the PCB where the solder is not accepted. Scraping the pads
a bit helps a bit but I don't think this is a solution.

Some details. I don't know where in the process it started but right now I'm
on page 15 soldering the capacitors. And it's nearly every third hole that
doesn't work. The solder sticks to the leads or the iron.

I use the same iron and solder as with the other 10 PCBs of elecraft that I
have built.

I contacted elecraft about this issue but I wanted to ask if others have
this problem too? What can I do?
