Hi Steve, Although your opinion is valid, calling something from a respected Japanese manufacturer crap is a little harsh. I have seen many people solder very well with all sorts of leadfree alloys - not producing crap. I've already had a play wit

ok, thanks can you explain me how I can be sure that the past solder it is not more usable? what tests can I do for having the certainty to throw in the trash?

I agree with Jim. Don't do it!!! The tech from SparkFun [on the YouTube video] is giving you his hobbyist trick, which: * For hobby prototyping will work just fine. * For production work, the process is not in control and should not be considered.

Hello! I want to inquire about settings for MPM printers with the Camalot inside system. We will use Koki JU-R45 adhesive and Koki S3X58-M406-3 solder paste with a 21ga needle. If anyone has a similar system, could you please share the initial parame

Don't do that! When solder paste dries out, all parts of the flux do not leave. The volatiles leave. Adding new flux messes with the chemistry and %metals and will not perform like new paste. If you can, get your paste in cartridges. It will last lo

Just come back from Nepcon (electronics show on an obscure little island on the other side of the pond) and had a good chance to look & play with a whole bunch of solder wire. Koki do one that is aprox. 99/0.7/0.3 with 0.03 Cobolt in. They claim th

Hi, We have seen a slight rise in failures in a product, and on investigation, the BGA ball has cracked off the PCB. It's below the intermetalic layer in the ball. Reflow otherwise looks good, and the raw components are clean. I am wondering what c
