MOTM

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 :)
