The problem is that they prove too large for this purpose: it measured 16cm long including 6 between the end and the "crossroads" of the branches. Which is pretty good. For against, the end of which terminates in "trapezoidal plate" 5 / 7mm x 8 mm. It is suitable for CI square "quad-in-line" kind QFP. It's already limits for CI "dual-in-line" or comparable SOIC. And it is frankly inappropriate for everything is smaller. Last thing, these tweezers are little chrome which become problematic for the kind of application that I made. Indeed, with age, with wear and shocks, there is always a risk for small shards of chrome stand and are glued on the slopes or worse on the legs of the components when soldering, resulting in Short circuits or difficult to diagnose failures.
In summary, if this will perhaps find its audience, in my case is clearly out. A purchase which I probably should think a little more ...
