Hi. I am looking for a printer that can print a conductive circuit on a thin film, like polyester or mylar film. Any lead would be appreciated. Thanks, bme

leadfree solder content to avoid wire being thin

Electronics Forum | Tue Feb 28 08:08:06 EST 2006 | davef

Tin is an excellent solvent. So, whether using lead-free or leaded solder, your wire will neck to one degree or another if the material of the wire dissolves in the metal of the solder.

The gold is compatible with your solder. Gold will dissolve in your solder very quickly. Assuming you have a fairly large [~ couple hundred pounds] solder pot, the gold will not, over the short term, affect the performance of the pot. The issue is

I learned yesterday that Kester is using a different color on their products. They thought that other manufactures would also follow their lead in this.

Kester R562 and using lead free components

We are starting to see issues with using Kester WS R562 with lead free components. The joints look grainy on almost all of the 0402'2 and other small components. Some of the solder does not solder to the terminations. These are hybrid boards which

What's the metallization on the board? We use an immersion tin board and had to increase our profile to successfully solder.

Krikies! seems like a head-scratcher if I may say so me-self. I would say the other ogre is right, that surface finish will play a big factor in your solder joint's grain structure or how shiney 'tis. Non-HASL bearing finishes will typicaly exhibit

My email mail machine couldn't send this to you ... Hi Stivais ... I didn't read the report. It seems to require downloading of a 'reader' of some sort. No thanks. If you would, just attach the report to this email. Regardless, energy-dispersive X-r

"Gap" in completed solder joint between lead and pad

Electronics Forum | Wed Nov 29 10:10:50 EST 2006 | M. Sanders

I'm sorry, Dave - I didn't make myself very clear. Yes, this space (not really a "gap") is filled with solid solder. For instance, if you place a gull-wing component in solder paste, after reflow, there will probably be a thin film of solidied solder

SMT fine picth connector lead oxidize-Throw out rate too high!

If you are a CEM you are setting yourself up for failure and will be left holding the bag. Flash gold has one purpose. It is a protective coating for the base medal to keep it from oxidizing. It is very thin and will be absorbed into the solder joint
