Ed and Paul, and the rest,
I guess my question was a little too broad maybe. Especially based on
the response generated. I was originally trying to let Yuan know that it
may not be easy to get such information.
From my standpoint, I am aware of the different factors you need to
review when considering moving from TH to SM. Many of which do *not*
apply to our product, i.e., we are not forced, nor are we pushed into
smaller PWB's, we also do not have a *need* to get more out of a little
package, we have a lot of high power devices which will remain in TH for
many years to come. Our product is analog based and the more 'stations'
we add to a product, the more space we need for analog voltage
switching, and lightning protection. So, hopefully you can see that we
are in an interesting situation.
In my process of determining pricing trends, I (an Manf. Eng.) have
spent many an hour/day trying to get some kind of actual idea of what
our real requirement is! I cannot even get our engineering department to
do a pilot of one of our existing units into SM so we can start to get
an understanding of what we really need. I did make note of your
comments on the pricing though, I just need to get some raw data to
substantiate claims....I even worked with 5 of our vendors (one of them
was Marshal!!) and that turned out mixed. The only real info I got out
of that exercise was that the DIP device and the SM device was the same
price, however the lead time was 6 weeks on DIP, and 4 weeks on SM.
I do appreciate the responses though. Let me share the corporate
philosophy: One of the other SBU's (another internal company) had a new
product designed outside, they wanted a bus style product that could be
expanded in the field, ala PC's. What we ended up with was a 18" X 18"
box with everything from TH to SM, single sided, double sided (TH *and*
SM), and a PCMCIA memory card, not off the shelf, CUSTOM!! Well, with
my limited knowledge and experience in SM, I cringed at the fact that
there are 11 different PWB assemblies, with one complete product
consisting of a minimum of 14 PWB's.
My thought is that this is a nightmare for our plant to 'jump into' SM
with. I see Contract Manufacturing in our horizon for a long time, maybe
not for the complete product, but at least for the super fine pitch and
ultra fine pitch assembly until we can get this TH plant educated and
trained on how to handle SM, and thus take advantage of the benefits,
like Quality, which I see as the most significant benefit to going to
SM.
Sorry to go on here, but I felt like I needed to amplify a little here
so people don't think I just surf and don't do any work myself!!
Oh yea, my fax is (619) 661-4424 and it does get directly into our plant
here in Tijuana, Mexico. Just put my name on it, I will get it!!
Thanks again for the helpful advice and any information I may be able to
dig up!
