After wash cycle, some of the inductors are open (broken wire). Resistance across the two ends should be below 4 ohms (normal) however on broken wire shows above 200 ohms. I am wondering if anyone else has seen this problem. We are using High-Reliabi

I have a big problem in setting an smd inductor camera recognition. None of the existing options in the software version 0.99B sems to work. The part is a 6x6mm with chamfer corners of 1mm on each side, looking more as an octagon. Not only this, the

hi, i am proccess eng solder wave process.I have problem with a PCB.There have ceramic SMD capacitor, SMD thermistor and SMD inductor 1uH.After reflow all is OK, but after SW these components are broken???The pin is separated from the body???the que

I just went through the same problem. We have an inductor that is made with a bundle of 30-strands of Litz wire that is vaccuum coated with varnish, and have the ends of the wire bundles tinned that we have to solder to SMT pads on the board. The ind

Hi All the other components on the PCB solder just fine, including resistors, ceramic capacitors, inductors, SOT23 etc. etc. so I do not think that it is a PCB problem. It is clearly focussed on this single component. Haven't yet tried scraping or
