How to solder a double side pcb without metal holes ?
on pictures to see in big...
the board to solder VIA = hole who link two tracks on
different sides but who are not a component leg hole.
Generaly i use resistors legs ( i always keep them when
i solder resistors) Put the pcb on a small foam support
, 0.5cm heigh is enough , but do not mask via holes
with the support. Insert resistors legs.
resistors legs on this side ...
||3) Ply them
at 90° , this will avoid they unsolder and fall
down when you will solder them on the other side..
your pcb and solder all the vias on this side
length of legs
IMPORTANT : Check if
you did not forget to solder a via and if solders are
good ( use a ohmeter) . It can be hard to modify some
of them when pcb will be populated. A very accurate work
is rtequired here !
Put ICs sockets
before resistors. It is highly advised to use sockets
on this kind of pcb.
Inclinated the pcb the approx +60° , it gives you
an easier access to socket legs. Solder only two opposite
legs on each socket , so you can still adjust their position
to be perfecly in place. Now you can solder the "components
side" sockets pins. See pictures.
pictured pcbs are Quad
VCA (released version) and MCV32
(final prototype ) boards.
