SN74LVC1GX04: SN74LVC1GX04

Part Number: SN74LVC1GX04

I am using the T.I. SN74LVC1GX04 in the DRL package, but am having problems with reflow soldering.  The SN95/AG05 solder does not want to wet to the package leads.  The DRL just floats on top of the solder.  The other chip components & various I.C.'s around it on the pcb look good.  Are there any app. notes to help with this or can you offer me any guidance?  Thanks

  • Hi Chris,

    That's an issue I haven't run into before. There's nothing unique about this part or the materials that the lead frame is made from, so I don't really know what to tell you. Is it possible that you have older parts that are corroded in some way?  That's the only reason I can think of that they wouldn't wet properly.
