In the meantime, the actors had obeyed his injunction, and the public, seeing that they were beginning to speak again, began once more to listen, not without having lost many beauties in the sort of soldered joint
which was formed between the two portions of the piece thus abruptly cut short.
Even gentle movements like vibrations from nearby hammer blows can rum a soldered joint
that's still hot.
Since the cooling of a soldered joint
after leaving the wave is affected by many factors--solder volume in the joint, the heat sinking effect of the parts involved, alloy composition, lead plating, and so on--the solder solidification will not be the same for all joints.
As soon as the soldered joint
exits the wave, it begins to solidify.

Generally, x-ray images of lead-free soldered joints
are similar to SnPb, although grayscales may be slightly different for SAC solder because of the absence of lead.
Provide brazed joints at all fittings when installing new equipment; no soldered joints
will be accepted 6.
With more weight, one of the soldered joints
In fact, it is often remarkable that fully soldered joints
will result when soldering boards with non-plated through holes, if we take a look at what can go wrong.
Much of this work is attributed to Darveaux, whose nonlinear material testing on actual soldered joints
has yielded crack growth data that can be combined with the viscoplastic strain energy density calculated to predict the number of cycles to initiate a crack and the number of cycles for the crack to propagate across the diameter of the solder joint.
Differences were observed between visual appearance for the lead-free and tin/lead soldered joints
, but more work is needed to test AOI inspection tooling.
X-ray inspection can highlight certain faults, such as voids, shorts, and undersoldered joints; however, equally serious problems like component or joint cracking and partially soldered joints
are not easily found.
