What should be solder paste stencil aperture proper size in comparison with PCB copper pad for lead free technology? When designing PCB foortprints I was using solder paste pad undersize of 2.5 mils (0.06mm) per side (solder paste pad size was 2.5 m

Hi Shriram, Are you saying that there is a trace running between the pads for this 0603 capacitor? If so, this design may be causing a gasketing issue between the stencil and the PCB. The uneven height prevents the stencil from sitting flat on the PC

Any lead free will eat a leaded designed wave soldering machine. But SN100c will eat it the slowest, our soldering tips used to only last 3 months with SAC305 when we changed to SN100c solder wire we are having around 9 months tip life. Our wave sol

@ Westshoredesign: Go take the top covers off your XPM's. Tell me if you see flux residue on the blower motors and the surrounding area. If you see this, grab ahold of the blower motor and rock it back and fourth. It is moves, the seals are melted o

My company has had the same issue on our Versaflow 366 with SAC305, we tried ultrasonic cleaning and it worked for a shift and then was clogged again. We have had the machine for 3 years and we have had to replace the gassing rings twice so far. We a

150º de-ionized water, however, if you're doing hobby work at home, regular hot water will be fine. Just be sure to allow the water to dry sufficiently before powering up the board. You can also use IPA or a custom flux cleaning solvent available o

From what I know, you should follow IPC standard for the class assembly that you are building. From your post somebody mentioned something somewhere - doesn't make it official information. I would not be worried about having voids, but what is their

Hi Etimov, Understood that to us assembling parts that IPC is king, however it isn't neccesarily the bible for design engineers. We've had customers demand almost zero voiding, or had to use conductive epoxy to avoid it. For some of us solder joi
