Yes. I'm at a loss as to how to best approach this. I think the giant blob of solder is just going to behave more like a lubricant than anything else. The thing is, I would like to at least try the manufacturer's recommendation once (and this bui

Hi Steve ... I found nothing in the manufacturers "paper" to help. Comments are: * I agree. No blobs. Solder on the thermal pad should me minimized. Too much solder will float the component. Old timers used to talk about 50-80% coverage. * If you'

Update - next run started out horribly so went to another stencil design. Reduced thermal pad coverage by about 40% with 4 panes, with cutouts to avoid the vias. Worked like a charm for 10 boards (90 parts). I think we're finally on to something.

The way to determine correct pressure (in my experience) is to start out at what you would consider to be a low sq. pressure setting. You are looking for it to leave a slight film of paste on the stencil. Start increasing pressure in small incremen

Hello, good choice! Koh young makes great reports for cpk. Only one advice. If you take 50panels from production and your cpk seems low, try to group the different kinds of components. Because also cpk on a whole panel would be not good number as wel

Why are you trying to use a stylus with Lightroom? Use a mouse. I can understand using a stylus with Photoshop, perhaps. Suggest you check the Lightroom help on https://helpx.adobe.com/ to see how others deal with it. Mike
