[Elecraft] Capacitor Lead Lengths - Always Critical?

Hi

It is ok for the caps to be a little above the board. If you try to push =
them down too much the leads will break off at the body of the cap. This =
will usually happen when the lead is heated to make the solder joint. =
Either bend the leads to match the holes or just press the cap down as =
far as it will go with out pressing overly hard then spread the leads on =
the back so it will not fall off then solder. Some of the caps will end =
up about 1/16 to 1/8 in above the board and that's OK.

  I've started to install the capacitors on the RF=20
  board.  Installing some of the small blue NPO=20
  capacitors (e.g., C154 and C144), it's not really=20
  possible to get them installed flush with the PC=20
  board, because the distance between the PC board=20
  holes is quite a bit greater than the distance=20
  between the component leads. =20

  Bending the leads a bit to form small "elbows" in=20
  them to match up with the holes in the PC board=20
  leaves the body of the capacitors about 3/16"=20
  above the surface of the board.  Is this OK, or=20
  will it result in some kind of undesired circuit=20
  coupling?  (Unlike the instructions to install=20
  some other capacitors, there's no special=20
  cautionary note about the "bulk" installation of=20
  capacitors I'm doing now, per the second=20
  instruction on page 49 of the manual.)

  If it's not OK, any suggestions as to how to get=20
  these kinds of components flush mounted without=20
  damaging them?

  Thanks kindly,
