MOTM

1) We are out of MOTM-960 boards. I will order the parts for 50 more, if you do 
not receive a MOTM-960 by the 20th, they will ship after Christmas break (around 
Jan 8th or so).

b) Same is true for the MOTM-910 mult. I am switching over to a pcb design 
versus hand-wiring. I have to tweak the footprint of the new vertical jack, and 
have more pc boards made.

c) remember, if you live in the EU, I *cannot ship solder*. You will have to 
provide your own. Check the archives for vendors and part numbers.

d) I may have miscounted the MOTM-890 available kits. If this is so, I will 
refund your money via a credit cart transaction or PayPal payment. I may have 
additional blank boards, but no panels.

e) Indiana has decided to kit up all 375 modules and then ship en mass. The 
shipping begins tomorrow :) I am going to try to add PHP code (God help me) to 
the SQL Server so that I can issue a 'partial shipment' status email (right now, 
I have a 'shipping now' status but that is hard to apply to a partial shipment). 
I may not be able to figure it out, so if you get a 'shipping now' email, do NOT 
assume it is for *all* that you have ordered. I just means  I suck at PHP.

earlier and it didn't turn up I think.)

No problem, I still have rolls of the good old leaded (60/40) rosin  
core stuff. Just to make sure: the parts and boards are not lead-free  
and need to be soldered using lead-containing solder, right?

What is the reason that you use two different kinds of solder  
(organic and no-clean)? I could not find that in the archives.

(Actually lead-containing parts/solder/etc. are still available here,  
as long as you basically do not manufacture anything new with it.  
It's perfectly legal for use in service and spare-parts for example.  
Also, certain areas of industrie are excluded for at least until 2008.)

With kind regards,
Ben

The organic solder has water-washable flux.  It is used for soldering 
most of the parts onto a PC board, which is then immediately washed in 
warm water to remove virtually all of the flux residue, leaving the 
board very clean.  Any parts that cannot be water-washed are soldered on 
after that with normal no-clean solder.  It is very important to wash 
off all of the organic flux, because it is corrosive if left.  The 
no-clean solder leaves some flux residue, but that is not as corrosive 
as the organic flux.

What parts are not water-washable, exactly?

I can guess the obvious: potentiometers, trimmers, ICs...

But what about caps and transistors? Are diodes ok?

(I haven't assembled an MOTM kit yet, so apologies if this is covered in the instructions)
