Thank you for support. As i promised you, I am coming back with the results. The SM used was Probimer 77 with Kester 979 flux. The supplier says that there is an incompatibility and we have changed the flux with IF2009M. Same problem! They have chan

SAC coated leads on certain components require more dwell time. If you find that you have top-side wetting issues, slow the conveyor down a bit or increase your wave height, or, a combination of the 2.

Hi Rob, I've decided at the moment to put them all over the wave, i'll keep looking into getting alternatives that are designed to be suitable and later on will hopefully switch some parts over. many thanks again Dougs

Sorry new to this... Question: will I have any problem soldering a resistor network with SAC305 coated leads using a normal leaded wave process besides the normal board thickness issues Thx

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

Hi, Does anyone have guidelines on minimum SMT component spacing for bottom sided wave soldering? I am looking for general rule of thumb in wave soldering bottom side SOTs, 0805 & 0603s. How about minimum through-hole lead to pad distance? Peter

I've never had one "float" in the wave. Have you tried waving yet to see? Anyway, glue would work, or you could place a a small weight on top, or clinch a couple of leads. Russ

Ooops, sorry Peter. [Those pesky decimal points.] I meant to say �150-200 thou�. There is a fair amount of 'Kentucky Windage' in this due to: * Height of the component and the down-stream spacing. * Chip wave capabilities.

Hi, I need to keep the gap between the T039 component's flat base and the PCB at
