Yes, Pb Free is coming soon... I am studying both Sn/Pb and Pb Free solders. Obviously the profiles will be much different for both pastes. Not to mention that one of my 0201 resistor vendors is switchng to Pb Free terminations in the near future!

In reworking 0201, we: * Cut the 0201 in half with a side cutter * Heat the solder on each pad separately and flick the half 0201 off the board * Preheat a new component to +150°C with a hot plate * Solder a new 0201 on the undressed pads with a hot

We're just now getting into 0201s and I'm wondering how people are doing rework. Is hand soldering still viable or is some type of semi-automated repair station needed?

We use precision tweezers to rework 0402 (OKI MFR-PTZ) not tried with 0201, but it may be a solution. The tweezers themselves have the heating element built in.

Are there solering iron tips for that size component? The C shape end ones. That might be even easier than cutting them first. I would think hand repair is going to be better than a semi-automated repair station for a while.

We're soon to build a lead free assembly with 0201 components. I'm not worried about placement as our machines can handle it. Any tips on printing, screens, reflow?

Hello! I have a strage problem, we made some production with uBGA, BGA, 0201, 0805, and other type of component. We didn't put the uBGA and 0201 and BGA on the board at the end of the line we look a our solder joint and surprise the solder made a

U may check your profile ramp rate. The flux may evporated and look like cold joint

Thanks, Dave. Really good article.

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t
