You say the resistor is blown. Is the body discolored? Is it possible that these are not the colors, like maybe the first GOLD is actually orange? Perhaps post a photo?

Hello, have some problem and interesting, does any body faced with same issue. On most of our products we have NTC thermistor(like on the photo), and during assembly process and handling great amount of components cracked on PCBA so we need to replac

Here's part of what I could read: "We evaluated the influence of Lift-off (Fillet-lifting) and the influence of thermal fatigue, in this case on combination between various terminal platings of electronic components and Pb-free solder, Sn-37Pb solde

thanks again for the feedback were your cracks mostly visible in relation to images shown in the document here: https://www.digikey.ca/en/pdf/t/tdk/guide-flex-cracking-mlcc most of our cracking has been lengthwise across the body which from what i

Currently experiencing a problem where the plastic molded bodies of tantalum capacitors are cracking during my SMT processing. Caught after our conformal coating process. I don't know where in the process they cracked. Currently running an exper

IPC states chips and cracks in glass body are defective if beyond specifications. Chips or cracks in glass body beyond the part specification, see Figure 9-18. • Cracked or damaged glass bead beyond part specification (not shown). On some glass

I have come across a rash of failed assemblies that have 0805 capacitors and resistors, bottom side glued, wave soldered and washed. Trouble shooter reported touching up the solder joints on a few areas and the boards would pass test. I had a look a

95%+ of my boards are small and therefore are panelized using the V-score technique. Getting a lot of resistor cracking even though the resistor is layed out to be perpendicular to the long board edge. What dimension should be used from the board e

I have seen resistors cracked during placement. The part was programmed incorrectly and the nozzle pushed down on the part too hard. I do not remember seeing any cracked during depanelization. Nibblers can cause damage if they are on the bottom and

I've seen crack on resistor also.The crack on ICs mainly is on the solder joint due to very high strain.
