Alkaline Earth Metals—Advances in Research and Application: ...
the desmear liquid in which carbonate ions are accumulated, the etching rate is
accelerated to be out of the appropriate etching rate range, thereby making it
impossible to control the degree of irregularity to be formed on the resin member
...

Industrial Processes and Waste Stream Management
The problem of smear is now considered to be only a result of poor drilling
practices. Two distinct methods of desmear currently exist: wet chemical
processing is most common, but plasma etching is seeing increased use. With
the wet process, ...

Statistical Process Monitoring and Optimization
From Figure 3 we see that the desmear/PTH operation of factory A (Fig. 3a) is
under statistical control; but the desmear/PTH operation of factory B (Fig. 3b} has
a record of an average of 1.0 point per month plotted outside the UCL of the T~ ...

Multichip Module Technologies and Alternatives: The Basics
This operation is referred to as desmear and is commonly performed using
concentrated sulphuric acid, alkaline permanganate solutions or oxygen plasma
cleaning. The solutions used also must make the hole walls hydrophilic to
enhance ...

Hence, it is important to desmear the holes in order to clean the holes after
drilling and texture the walls in preparation to plating. The smeared epoxy needs
to be softened and dissolved away. The boards are first treated with a mixture of
a ...

X-Ray Scattering of Soft Matter
The solution is either to desmear the scattering pattern or to correct the
determined structure parameters for the integral breadth of the beam profile (Sect
. 9.7). 4.1.1 Point Focus Collimation Smearing. Because scattering is emanating
from ...

Copper and Copper Alloys
In the past, electroless lines were designed for two-sided boards only. The
multilayer desmear process was entirely separate, thus requiring additional
unracking and reracking between segments. Most electroless copper plating
lines now ...

Evolvable Designs of Experiments: Applications for Circuits
The drilling or ablation causes smearing or residues of epoxy resin on the inside
of the holes. Aggressive chemicals remove these imperfections. Hole cleaning
refers to a process called desmear and to the closely related process of etchback.
