This new selective soldering offering features Nordson SELECTs unique automatic solder
nozzle tinning system.
When purchasing solder
it is important to understand the differences between lead and lead-free options.
To study further the potential of Sn-0.7Cu 0.05Ni solder
alloy, there is a need to assess its corrosion behaviour as it is an important factor to consider in formulating new solder
By adding nanosized [Y.sub.2][O.sub.3] to the Sn-58Bi solder
, it could be found that the spread area of the composite solder
alloy was increased by 20% from 30 [mm.sup.2] to 36 [mm.sup.2] and then declined to 32 [mm.sup.2] with the addition of [Y.sub.2][O.sub.3] nanoparticles added from 0 to 3.0 wt.% .
The highest value of the ultimate strength of 196 MPa reached Zn-Al4 solder
and the lowest Rm reached ZnAl1 solder
The inventor of the All-In-One Hander Solder
Gun previously developed a working prototype that was utilized with success for a period of time.
balls in 300pm-pitch BGA packaging were fabricated by stencil-printing solder
paste and then reflowed at high temperature.
Efficient heat transfer ensures that the solder
material melts, forms a joint, and solidifies .
But, when it comes to fine pitch application, solder
balls have the tendency to agglomerate between the neighboring electrodes resulting short circuit.
If you find one, first remove the blob of old solder
with desoldering braid (from an electronics store) or an old piece of lamp cord (Photo 1).
The Patriots and Solder
, the team's first-round draft pick, finally came to terms on a four-year contract, and the rookie, wearing No.
Since most surface mount components are small in size and weigh on the order of grams, the inherent strength of the solder
pads on which they are affixed was never a serious concern.
