Wire soldered directly on the PCB | 3 June, 2013

Hi,

I have a design were power supply multi strand wire (AWG18) are soldered directly on the pcb (thru-hole) by wave soldering process. I don't have any ferrule on the wire.

I would like to know if the IPC standard allow this for class 3 assembly ? I didn't clear find information about this.

Thank you

Stephane

I don't see any requirement for a ferrule on the wire. As long as your insulation clearance is twice the insulation diameter or less and the insulation doesn't interfere with the solder joint, it should pass Class 3.
