Hello, I know I will probably get a dozen "check the archives" answers, but what the heck. What is YOUR typical polarity mark for SMT devices? Do you use silk screen or cut a corner off a pad? Let me know and thanks.

I don't think 'this a blatant violation of rules' as such. I think it is a blantant disrespect of the principle of free and open communication that is the corner stone of interenet forums and a slap in the face of everyone that wants to learn more a

You're thinking correctly. Concentrate your recipe development efforts by profiling directly on the pads [that some fine designer forgot to thermally isolate properly] of those pesky corner leads that don't solder well.

I may have a similar problem at the moment with a QFP-68. Do the unsoldered leads leave a perfectly formed footprint in the reflowed solder? Do you usually find this issue occurring towards the corners of the QFP rather than in the middle of a row?

Polarity in tape and reel is usually always on the bottom left side. And that is correct for the trays, they have a corner taken out where the polarity goes. Hope that helps........
