content: Hi,Has anyone found any good tweezers specifically for handling e.g. 0603 / 0402 passives.I usually use Lindstrom TL 7A-SA-SL for this, but I find the component swivels easily on the points of the tweezers.I'm looking at, for instance, the PT-24 or PT-28 here?http://www.engineer.jp/en/products/pt18_28e.htmlTIA, Alan

content: I like Dumont tweezers which are available in a dizzingly large product line of various materials (including brass) and qualities. i.e. non-magnetic, medial, industrial, and so on.I find no one tweezer does it all. My goto tweezers for most work is the #3https://www.ebay.ca/itm/Tweezers-3-Dumont-Hi-tech-Antimagnetic-/400917618361For a bit finer control on smaller parts the #2 is my goto tweezer:https://www.ebay.ca/itm/Tweezers-2-Dumont-Hi-tech-Antimagnetic/183069926477and for even finer work i.e. 0603 and smaller, the #5 is my goto tweezer:https://www.ebay.ca/itm/Tweezers-5-Dumont-Hi-tech-Antimagnetic-/401292936160Dumont is just one brand name, there are others but the numbering sizes are pretty much universal in the industry but may not match directly others numbers like PT-24 (etc).Any good jeweller, or watch and clock maker will have many choices.cheers, Graham

content: Please take care that the tweezers you are proposing (PT-24/28) are for manipulating (mini)MELF components or non-standard SMD components!Take a look at the following pictures (and the whole thread):https://www.eevblog.com/forum/buysellwanted/on-ebay-lindstrom-tweezers/msg57905/#msg57905as a reference to tips size and 0402 components.Even if I own lots of high quality tweezers, my favorite ones are the Lindstrom SM-108-SA which can be used with large SMD components (2512/1206) and rather small ones (0402):https://www.eevblog.com/forum/buysellwanted/on-ebay-lindstrom-tweezers/?action=dlattach;attach=12491;image

content: >>> Please take care that the tweezers you are proposing (PT-24/28) are for manipulating (mini)MELF components or non-standard SMD components!Yeah, I was aware that they have circular indents rather than square ones - I was thinking that they would probably hold square components OK though.Maybe, it's just me ... but I find when hand soldering say 0603s that after tinning one footprint pad, that when sliding the component sideways with the tweezers onto the hot solder on the tinned pad that the component tends to rotate upwards onto the solder around the points of the tweezers. Some little 'edges' on the inside of the tweezers would stop that rotation.Alan

content: Try the SM-108-SA: they "grip" better the component because they have more tip surface (against the pointy ones)Do not buy the dedicated (mini)MELF tweezers: I own them and I never use them. They are good only if you make a lot of rework with MELF
