Our board layout folks are currently designing a PWB using a 132 QFN. The component is .5mm pitch with .35mm square pads. The component manufacturer recommends the following footprint: .4mm square land .3mm square solder resist 1.why do they spec

We believe that many manufacturers' recommended pads should be close to the last resort. Recommendations are: * Standardize with the IPC guidelines or those by Jim Blankenhorn [ smtplus.com ]. Anyone that wants to change from that standard needs to

I am designing a component for surface mount. Does anybody out there specialize in the design of passive components for SMT? Can you recommend a good reference?

Ben, I'm not aware of any 'automatic' method to convert PTH footprints to SMT. Typically, many of the components are passives, and there may be a way in your CAD software to change the passives of a common size to a different footprint. That will co

Hi, Is the footprint per the component manufacturers recommendations? The reason I ask is because it kinda looks like the pads are extending beneath the component. Could cause the part to float up on top of the solder and not allow the leads to wet

You can adjust to 45mm clearance, But I would recommend staying at 25mm if working with fine pitch and smaller passive components.

You might find what your looking for in the component datasheet or at least a recommended footprint. As your looking for advise I would speak with whomever you have your stencils designed by at the min, they likely already have a database of options

Hello, does anyone know if it's possible to wave solder 0402 components? Are there drawbacks? Where can I find technical details about recommended footprint and glue point? Last question: are there suggestions about wave soldering for ic with 0,635mm
