Does anybody have any experience or knowledge of processing PCB assemblies featuring pyroelectric sensor devices, the type used in Passive Infra-Red Sensor modules? Since these devices are, by definition, very sensitive to heat, how do you get round

We are due to build a board with a few of the Andon Image Sensor Connectors on and was wondering whether anyone has any experience of these devices? Manufacturing guides, inspection guides and rework guides?

Have seen similar problem before with regards the MSD being the cause. But also seen similar defects being found at functional test as the in-circuit test was injecting to much current during test. The devices were walking wounded afterwards. The in

You know, Rich - if the only problem with your present method of delivery is that the container runs dry and the pump sucks air you can add a non-invasive low level alarm quite simply and for about $100. A suitable adjustable sensitivity capacitive

We are using a smps for our comm pcb , a relay and a current sensor, which uses 4.2v, 12v and 5v respectively. We are controling one phase of a three phase 5hp water motor. Also smps circuit and relay output are in parallel so output load doesnt effe

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

Hi all. First off thanks in advance for any help or suggestions you may give. What I need help with is making a 4x4 keypad overlay work again. I have the overlay and the PCB, all I need now is a device that connects to the PCB that senses the push of

I am supposed to heatsink a Temp sensor with leads .9-1.1mm(.035--43"). I have found on our engineering units that the smallest heat sink I have found commercially is still too heavy for the leads and unless the operators use exxxxtreme care the wei
