Yay, package from Hong Kong, must be DealExtreme! Ordered literally months ago, almost forgot about it!

@ obviously if you get the largest capacitance for a given voltage you will always have problems. tolerance can be very good.

@ i though it was propylene glycol or something similar. not too far from antifreeze. :-)

@ yes. 180C is where i set the hotplate, but actual temp depends on many things, like groundplane on bottom of board, etc.

Here is a beautiful MCM (multi chip module), in this case a Linux PC. All of this is inside one IC pkg!

Cell phones are constantly pushing the envelope of semiconductor packaging technology. Chips may hide more components, multi die inside!

Example (iPhone): look for PA in upper right. Most other components 0201+

Fun fact: Most cellphones today contain power amplifier chips that consist of a 5x5 QFN part with 20 or 30 01005's and 2 or 3 die inside.

@ yes. it's not that hard if you can see what you are doing. worst part is - they ALWAYS stick to the soldering iron tip.

I need to clarify. Smaller than grains of iodized table salt. I'm sure there are truck-sized salt crystals that become the spice.

@ I won't even do 0805's without a scope. Why work on things you can't see? And I have good eyesight!

I need to create a project that uses 01005's just to show that components smaller than salt crystals are useful. 0805 0603 0402 0201 01005!

@ oh, forgot the most important part. hot plate for preheat. night and day difference.

@ lol, i used to work with 01005's. 0201 is large! advice: scope&light, flux, Metcal w/fine tips, paste in syringes, patience!
