Clever idea. I used to work on hybrids. baking temp about 850 degrees C we used titanium and ceramic substrates. the high temp was needed to make the resistance layer partially melt. remove the resitance and you can run at the silver melting point an

I'll answer the easy part. If you put low temperature trays in the oven at 120C, they will warp and partially melt. I have seen it more often with reels of LEDs. Someone is told to bake them before use so the put them in the batch oven and the next

The homologous point is the temperature midway betweeen the melting temperature (of the solder) and absolute zero. Below this point the solders are harder, stronger, and more resistant to fatigue. As solders are exposed to higher temperatures above

We have to perform a wire modification on a PCB. I am looking for a wire where the insulationmaterial does not shrink or melt when soldered.

We use 30 and 32 gauge PTFE wire. The insulation will not melt with normal hand soldering temps. The wire was made by Thermax/CDT. Their phone number is 800-423-5873. The only problem with the wire is that is hard to glue to the board. We use Ta

Dave, Thank you for your comment. Besides the concerns that I had in my mail, it Looks that it will take about 15 minutes to change a chip, and this is not acceptable for our process. Thanks again. Have a good day. Albert Hay.

Hello Wolfgang Try looking in the process guides section of Circuit Technologies web site. Their recomendation is to bond the jumper wire to the board within 6mm of the lead with hot melt glue, cyanoacrylic glue or adhesive dots. John Thorup

What is the liquidous temp for: 95Sn/5Ag and 96.5Sn/3.5Ag thanks in advance

Hi Brian, Here is the web address for Indium. If you go to the "technical papers" and then to "specialty solders and alloys" they have a really great chart that has all the alloy specs. Well worth printing. ........Jeff Sanchez
