No clean solder

[moe-20]

Hello all

I am also building a K2.

Can't get Kester here in UK.

Is it OK to use Multicore no clean solder crystal 400 Halide free.

If you can find Multicore WRAP 3 (370 flux), you can be certain it will work.

I suspect the crystal 400 flus will work as well, but I have no experience
with it.

Thanks Tom

I already built control and front panal board using crystal 400.

Is 370 flux no clean or usual Rosin core?

Multicore web site Loctite is quite useless for older tech info.

thanks for your help.

The Loctite web site is useless for practically anything.  However, a  
Google search turned up the following site, which mentions Multicore  
370 as being an activated rosin core flux.

http://www.logwell.com/tech/servtips/solder.html

FWIW, I built my K2 with Multicore 63/37 type X39C, which was lobeled  
as 'no-clean' but I have been unable to find any definitive data for  
this, although it behaved similar to other mildly-activated fluxes.  
It didn't seem to be any more difficult to solder than with more  
active flux, although there was little residue, as expected.

Hi Bob

Thanks.

I just want to make sure it doesn't give trouble later.

I am using crystal400 halide free.

Actually , I was using crystal 511  multicore for various things and seems to
be OK.

Just I want my K2 to last all my life or may be most of my life.

Hi Moe,

In my search for information on X39 flux, I found (via Google) some  
information from Rapid Electronics which also descripes Crystal 400  
and 511.  It doesn't appear that there should be any problems with  
either of these.

I tried to send you the data directly as an attachment, but was  
unable to do so.  You can download it from <ftp://n7xy.net/solder.pdf>.
