We ban silicone from our shop. It makes connections unsolderable.

Silicone for bonding?

Electronics Forum | Mon Oct 06 18:41:47 EDT 2003 | davef

In addition to our earlier comments, do not be misled into thinking that silicone materials, being rubbery, will transmit shock less. Nothing is farther from the truth. Many silicone rubbers are almost totally incompressible in the short time scale.

Hi Everyone: Does anyone know what the right silicone for bonding the pressure sensor bare die on PCB is? How do I prevent the fracture and keep good adhesive? Any help would greatly be appreciated. Regards, Jalinous Esfandyari Intelligent

Silicon contamination in solder joint

Is anyone aware of any reports, studies, articles on the subject of silicon contamination in SnPb solder joints. We are evaluating repair of conformally coated (silicone) boards. The fear is that we will never totally remove the silicone and once i

Yes we are using "silicones", but to find this contaminant we were looking for "silicon" the element by SEM/EDS. We use Dow materials and my contact there is checking to see if they have any info.

Hi Bill You said, "silicon". We assume by your discussion that you ment to say, "silicone". For background on silicone and soldering, check with Dow Corning [517-496-6000]. They make a OS2 [VOC-free] silicone stripper and should be able to give y

Silicone Grease where is it used?

I just purchased a soldering station and it came with the silicone grease for the desoldering gun and say's for cleaning spring filter and filter pipe, now do I just smooth this grease all over the spring and tube the spring goes in?

Wow, you're very correct. I guess we use silicone to calibrate our machine, as follows: XPS spectral measurements of dimethyl silicone should include O(2s) at 25 eV, Si(2p) at 102 eV, Si(2s) at 153 eV, C(1s) at 285 eV, and O(1s) at 533 eV. The C(1s

Silicone Conformal Coating

I have a need to have a number (approx 20) circuit card assemblies which need to have a silicone conformal coating applied per MIL-I-46058. Are there any facilities which can offer me this service? Thank you, Chris Fontaine (603)885-6839 Sanders,

Chris, You may wish to contact Colin Burnie at SigmaVI in Melbourne, FL at 407-255-3559. They have coated boards for me using acrylic with very good results. I can't remember though if they do silicone. They have no problem with small lot sizes. B
