Ferrite Core cracks

Electronics Forum | Thu Apr 01 20:07:06 EDT 2021 | smith88

Is there a standard that gives criteria for cracks in Ferrite Cores? I have reviewed Jstd-oo1 G and IPC 610 G and do not see a specific reference to Ferrites. Thanks for your help

I am currently placing aprox. 95 to 100 1206 size ferrite beads onto a pcb and having difficulty solding these parts. They appear to be soldered when the board comes off the reflow, but you can flic the parts off by hand. We thought they were contami

I've seen that before, had to switch to a no clean process for those boards. It's not typical for ferrites, usually its safe to wash them. Out of curiosity does the Data sheet say anything about whether or not they can be washed? In my case we lear

Hi Pat, is the soldering Ok when you solder them by hand ? We use some larger ferrite beads with no problems in reflow but I must say that we use a vapour phase and only max 5 parts/PCB. They do have a high thermal capacity and you use a lot of them,
