How do other folks handle
vias on double sided pcbs?
I have tried two methods
1. WIRE
Place a hole close to each via
and use this to solder in a piece of
wire. I put a letter "v" in copper
on the bottom side of board next
to the hole so I can quickly check
that all the vias are taken care of.
Of course this means you have to
drill more pcb holes.
2. INSERTS
I got some gold plated MillMax
inserts that fit into a drill hole and
are hollow and big enough for typical
resistor and dip leads. I think the
OD is about 0.039". You have to
be careful when you solder them in
because the solder tends to wick
into the hole. I do not have the
part number now and the last time
I looked no one (Digikey has
some MillMax) was carrying them.
This seems to be the neatist
solution to the hombrew via
problem. However I only have
a few left, so I will have to find
another source. If I have to buy
thousands, is anyone interested in
a group buy?
