I would suggest you get a copy of the classic Klein Wassink book 'Soldering
in Electronics' (ISBN 0 901150 24X).

Wave soldering SOICs, I would add extra pads at the trailing end of the IC
connected to the last pads of the IC by fine tracks with no resist on.

Hi Steve,

Thanks for the prompt response.

What kind of solder thieves should I put in, say a SOIC08? Do I need to put
in
leading pads and leading pads? Is there any standard published that I can
find
or buy regarding wave soldering issues?

Thanks for the support.

Patrick

Hi Patrick,

If you look at say a side one footprint(reflow)for quad flat pack as opposed
to a side two (wavesolder)side. On side two you will ideally need to present
the component @ 45 deg to the wave and have solder thieves in each of the
four corners to eliminate solder bridges.

just an example.

hope its of some use.

Hi Technetters,

Is there a need to have different SMD land size/ pattern for wave soldering?
Any
suggestion is appreciated.

Thanks,
Patrick
