The diaphragm of the microphone is a very thin mylar membrane, it
is easily being contracted and distorted with the high temperature.
Therefore, we can only use hand-welded method to process, and the
temperature of soldering iron cannot over 330°C,
the welding work should be done within 2 seconds,
the faster the better.
The best way is arranging the skilled welders to solder one wire/
pin first, and then finish the left one after the microphone cool
down, this can avoid the high temperature causing distortion of
the diaphragm, the worse sound receiving results or even breaking
Otherwise, you can entrust the manufacture to us, our factory has
special manufacturing tools to help the microphone cool down. Besides,
we will test the sensitivity again after soldering in order to keep
the qualification and the reliable quality.
The tooling as microphone heat sink, prevent heat damage.
The microphone itself need to aim at the sound hole of the mechanism
case, and being as close to the surface of the case as possible
in order to gain the best receiving results.
Trying to use rubber holder to
separate the outside noise, especially the wires type assembling
method can do good to fix the microphone on the case of the mechanism.
When we fabricate the microphone, no matter adding rubber holder
microphone should be pushed to the bottom of the mechanism,
to avoid a chamber forming in front of the sound hole and affecting
the sound which microphone receives.
