Why do you feel the soldering is poor? We have not had a single
failure due to poor soldering. We have approximately 400 units in the
field at this time. The field failure is around 0.2% during the one
year period that these units have been on the market.

=======
That would mean that only 1 of the 400 units had failed in the field.
Is that correct ?

Along with maximum splatter.


In looking closely at his photos, it appears his circuit is based on the
Analog Devices SSM2166 (product data:http://tinyurl.com/6eadpn). The
specifications indicate it *can* be operated cleanly. Of course, to set
it
up requires at least an oscilloscope... which many hams don't own (or
know
how to use).

Based on the photos I've seen, I wouldn't buy one because of the poor
soldering:http://img105.imagevenue.com/img.php..._122_173lo.jpg.
I'll just continue to use my 2-tube (2x 3-500Z) speech
"processor":http://www.rigpix.com/linears/sb220.htm

According the photo (http://i17.ebayimg.com/06/i/000/cb/2d/2695_1.JPG) that
I found on a certain well-known auction site, all but a few solder joints
had what I call "reverse fillets". The solder connections should have a
concave shape but instead have a convex shape (too much solder). The few
that didn't appeared to be overheated, with a grainy appearance. I hate to
say so but, though you've had a low failure rate, they definitely wouldn't
pass scrutiny to meet Mil, CGMP, ISO, or IPC standards.

Absolutely correct Frank... and the failure was not a soldering issue.

You are right about possibly having too much solder... but that is
certainly not a reliability issue.
Grainy appearance of some joints is not uncommon for the new RoHS
(high-concentration of tin) solders.
As for passing military specs... that was never our intention with
this product. Thanks for your comments.

LOL.

His website claims that Mouser Electronics is a "partner." Searches on
Mouser for "Telstar" and "VoiceMax" return zero results. Hmm. . does buying
some parts from Mouser make them a "partner." If so, I'm a "partner" with
Mouser, too.

The dictionary defines partner as "One that is united or associated
with another or others in an activity or a sphere of common interest."
So yes, in your example... you would be a partner of Mouser.

If I advertised that my company was a partner with HP (we bought the
computers from them) and Kenco I think they may object .......

Well... I can't speak for your business... but my partners are
overjoyed that they are mentioned and have links available to their
sites.
