How are these wires bonded?

This connector is from a Chevy Cobalt, but I think the question is more about electrical technology than automotive stuff. Feel free to close, if I'm wrong. One of the (5) wires attached to the lug (below) does not have good continuity. Bonding to…

Why is electrical tape not very sticky?

Over the years I've used lots of different electrical tapes, cheap and not-so-cheap. One thing they've all had in common is that, while pretty tacky to the touch, it never sticks very well to anything but itself. Just this afternoon I've been using…

Conductive Adhesives?

I'm helping with a kid's Maker's project. We need to attach some LED's to some coin cell batteries for part of a holiday project. Are there any conductive adhesives we can use for this? Durability is not a factor, since the life of the project…

What adhesive is best to glue strain gauges to metal?

I'm trying to use these strain gauges to measure bending of a metallic cantilever (metal TBD). Does anyone know what adhesive I can use to glue the strain gauges? I'd rather not have to use an oven for curation, unless it is my very last…

Danger of high voltage in electroadhesion

I am currently doing my master internship to get a degree in mechatronics. For an experiment I would like to conduct, I am interested in using electroadhesion. For those who don't know about it, the principle is easy. Get two electrodes (side to…

How to integrate a conductive adhesive sensor

I am working on my final project for uni, in which I am building an electrical circuit using a force sensor that has conductive adhesive. I am unsure how to integrate this sensor into my circuit, meaning I am unsure how to connect wires to it since…

What kind of glue should I use for PCB-mounted components to increase rigidity and stress relief (not vibrations)?

I have some small boards that have various connectors, JSP, female headers etc. Those connectors and headers will be used a lot with various devices plugged in and pulled out and will get a lot of mechanical stress. This will be rotational, angular,…

Is thermally conductive epoxy needed if long settling time is acceptable?

I'm using SMD based analog temperature measuremet ICs (a version of the old TMP36). It will be mounted on a tiny and thin (.5mm) PCB I've cut to hold the IC and a few mfgr recommended parts and a 3 pin header. That assembly will be fixed with epoxy…

best adhesive for FR4 to aluminum

I am making my own LED bulbs (for wedge-base sockets in a low-voltage application). A key construction detail requires me to cement a small (roughly 3/8" x 1") piece of FR4 circuit board (which plugs into a wedge-base socket and holds a couple of…

Is there an appropriate "potting" compound for a DC power barrel connector?

I need to modify the DC connector on about 100 AC/DC power supplies and will be installing a barrel connector like this: I would like to make the connector more permanent and prevent a user from opening the connector as well as increase the…

Hold a SMD chip on the PCB with Scotch tape

Background: I'm watching many SMD soldering tutorials these days, but I'm still not ready (too nervous!) to actually try it with my PCB and DAC TI PCM5122PW: Question: Can I put the SMD chip on the PCB and hold them together with Scotch tape…

Best way to hold a slightly twisted, castellated-hole PCB board to another during reflow/hand solder?

I have a 31x61mm PCB with castellated holes that are slightly twisted - enough to prevent it from having great contact to the other PCB during baking. What I currently do is place the PCB by hand and manually solder down the castellated holes. Any…

Dissolvable glue for glass to PCB adhesion

I am working on a project where I have designed a MEMS sensor on a glass (quartz) wafer. I also made a PCB where the glass sensor chip is to be glued to the surface of the PCB for testing purposes. However, since I have more chips than PCB's I would…

Is it safe to patch a capacitor with some aluminum housing exposed?

I was removing some capacitor adhesive and noticed that in doing so I ripped off some of the capacitor housing causing what seems to be the outer aluminum shell to be exposed. The capacitor itself is still giving perfect readings. What would be the…
