It's possible that there is limited application of "3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719" similar to your intended use. What do 3M™ application types say? Certainly high temperature soldering would make a mess of a piezoc

Now that I've seen the pics... Soldering could work just fine. If you are going for large production then you could get copper discs cut and mounted in tape carrier ($$). This would make it very easy for automated equipment to assemble. Mounting a

If the sensor can survive the 200C in the molding machine, then could it not survive Pb-free soldering? Maybe not convection reflow, but it should be able to survive vapor-phase reflow. I would control solder height by controlling the amount of paste

Thanks on the advice isd.jwendell! Yes, the piezo ceramic has a Curie Temp of about 800C, so its safe operating temp should be around 300-400C. How about if my PCB is a prototype, would it be more economical to use hand soldering or just manually app

Hi everyone, I need to connect a cylindrical disc device (piezo ceramic sensor) to the PCB trace without using high temp solder. I plan to use "3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719" to connect the device to the PCB trace

Thanks Davef! 3M's product description of "3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719 is suitable for attaching low surface energy (LSE) EMI shields to electronic and electrical devices where high temperature (up to 400C) is re

Unfortunately, I don't see any image. If your part will survive 300C then even convection reflow should work. The use of paste and reflow ovens are for when you move to production quantities. It sounds like you could hand solder your prototypes (proo

Wow! Thanks Jim!. When the ejector pin hits the piezo ceramic sensor, the sensor will produce a voltage difference between the top and bottom surface(that's why i need to connect the tracks on both sides) which i will measure. The sensor does not ne

Hi all How can I find the technical paper or source of information about using No-clean flux with high frequency apllication. High frequency mean more than 2 GHz - 5 GHz. I heard from my colleague that No-clean flux residue on board effect to high
