Hi All !

May have misunderstood something here, but all MOTM pc-boards are
roller tinned . Totally superfluous to tin the tinned board again %^)

And on a freshly home-made board, even before drilling, i spray some
kontakt chemie solder laquer, keeps the bare copper from oxidising
and solders beautifully .

When soldering the coax to the boards, i start with the core . I
found that when first soldering the braid, many a time the center
conductor is then put under a bending load . When soldering takes a
tad too long (this can always happen :) ), the hot core wire will cut
through the poyethylene insulation like a hot knife through butter .
Hence i start with the core without bending it much at all . Then
the braid, not tight at all, so there is some air on the component
side . And i do not twist this, close to the core . This again to
put no cutting strain on the core . This bit of slack is neatly
tucked under when fixing the coax with the tie .

Cheers .


Keep 'em oscillating :)
