If the board is HASL you may always have trouble. Try to reduce the amount of paste by either reducing aperture size of stencil thickness. Jerry

Is an RQFP a Qfp with the center pad for heat dissipation? If so, you may be shifting when this center pad reflows and lifts the part.

What's your pad geometry/sizes relative to lead width/length? Revisit this and my free website: http://www.moonmanondarkside.com and see some examples and download some free documents. MoonMan

I have a vitronics oven, model smd-722. I am looking for the controller software for it. I need the 20-zone version 8.3. Does anyone have a copy of this in their old software archives?
