Can someone from this forum provide me the value for acoustic impedance for silver-glue? Would appreciate it someone can help.
Some people called it as silver paste or silver epoxy.

I am looking for a electrically conductive epoxy that can provide good contact for a Silicon chip gold-metalized backside at 10 GHz, for a month or two. Then I would want to disolve the epoxy (alcohol, acetone, etc) easily, or just peal off the chip mechanically, and allow the chip to be removed and reinstalled in a final circuit without damaging

I have heard this stuff is very thermally conductive. I have used other silver epoxies on alumina with but not to 20 GHz. There was a silver epoxy that had long term failure (about 3-5 years) in conductivity so be sure to get that data from the manufacturer.

There are a couple of ways to fill vias and make them airtight. You should discuss it with your board fab.
One way is to fill the via with silver epoxy. This is one way vias are filled under at BGA with via-in-pad, for example. But it also works for vacuum filling. It can be expensive depending on your fab. For fills to which you will solde

I'm designing a 2-18 GHz coupler which requires gross leak to mil standards. I have a body and a cover fabricated out of 6061T6 aluminum - and flange mounted connectors... what is the best way to seal up this body.
You do not specify the leakage level. Good commercial couplers are sealed by machining a notc

I was watching a youtube video on how to make copper nano particles by mixing copper sulfate solution with ascorbic acid solution.
It got me thinking how else you might be able to achieve this with some other chemicals I had laying around from my chemistry days in high school and university.
I happened to have some sodium metabisulfite and that

anybody has experience on finishing-plating microstrip circuits?. I have read that in electronics is usual the hasl finising and also an organic finishing called osp. other alternatives such as inmersion gold, inmersion silver and NiAu plating are commented.
can somebody in a simple way describe advantages and drawbacks?. soldering is a require

hello all, what I can use to adhere a chip without its package (just the die) to a normal cupper PCB ?? The material should be conductive or must have other properties to avoid ESD ?
silver filled epoxy is what I called for on a sensor board I did a few years ago.
The die mounted to a die mounting pad on the board that h

To simulate you first have to set up the substrate layers as following:
for example using a PET dielectric and silver cond.

Thanks for that advice but I have tried a slightly different way. The pin broke off inside the base glass in a little hole. I couldn't get to the pin to solder so I have filled the hole with silver paint and epoxied a new pin in. The lead appears to be in good contact with the end of the wire so I hope it will work

you can also use silver and carbon conductive inks in your design
application is done using screen printing

You don't plug using solder mask.
You plug your vias shut with various conductive materials (silver, specially formulated paste, etc.)...but not epoxy.
Plugging your vias (with conductive material) will allow for better connectivity, and the holes will be free of corrosion over time.
Tenting (plugging with solder resist) helps to assembl

I have some parts that came with screen printed electrodes, over time the electrodes have worn off and now I can't solder leads to the parts at all. I have tried using rosin flux and acid flux to solder the leads back on. I have tried putting on new electrodes with a silver paint and a nickel pen but they just melt into the solder. I have tried glu

In this series of laptops, the Nvidia GPU fails due to overheating (bad thermal design). It needs a reflow of the chip and a small modification - replacing the thermal pad between GPU and heatsink with a copper piece 2mm thick. Also good quality thermal paste is to be used (like Arctic silver). Apply this paste (small quantity) on the GPU and place

silver solder that evaporates or is epoxy with >99% silver content is $$$ but can be painted on. Hobby shops have nail brush applicator for simple fixes. but 30AWG magnet wire or WW wire is trade solution for jumpers.
What is it for?

You can plate alumimun housing to be solderable. Typically one nickel plates first, and then applies a thin layer of tin or gold on top of the nickel. Theoretically you can solder to the nickel, but it tends to oxidize right away and is hard to solder to.
You CAN epoxy the unit into the housing. There are silver loaded epoxies, either in past
