Audio Jack connector came adrift
|
Ok so this is not a complaint and it was very easily fixed. I discovered my jack socket wasn’t working and appeared loose. Easily fixed in a couple of minutes with some good old full fat leaded solder.? I’m just sharing this for information in case others possibly have this same issue.? Thanks. Peter |

This is not necessarily a failure of unleaded solder (although I hate the stuff too). There is not enough solder there to start with. This is a common issue with machine soldering of large parts that may be under some degree of stress. External connectors, power components, etc. The amount of solder on the pad is quite sufficient to handle smaller parts that just sit there, but larger parts that are subject to repetitive stress for whatever reason can develop fractured solder joints over time.
Your fix is good, but be careful with your headphones. Your next failure will be the jack sheared away from its legs from a sideways jerk of the cable. I saw this often in the wireless intercom belt packs that I used to work on. 73 -Jim NU0C On Sat, 10 Feb 2024 06:49:07 -0800 "Prawlin via groups.io" <prawlin10@...> wrote: Ok so this is not a complaint and it was very easily fixed.

开云体育Thanks Erik. Just sending pic again hopefully at better resolution. If you zoom a little, you can clearly see the places where the connector legs originally were. I had only used the connector a few times and had not knowingly exerted any excessive forces. Some insertion force is unavoidable with that particular Jack design. I wonder if gentle twisting of the Jack plug whilst inserting might reduce the risk? Then again, it might increase the chances of the blobs fracturing by twisting forces? Maybe adding a tiny dab of contact lube or silicon grease might allow easier Jack insertion/removal? I’ve considered carefully adding a tiny amount of thin cyano to bond the connector to the PCB. It is unlikely to ever need replacing in the future (though I can hear some groaning now as I write this) I still blame the lead free solder. I’m retired now but in my career we lived through the introduction of lead free and it caused no end of similar joint fracture problems.? I’m glad the same didn’t happen with the USB C as that would likely result in hard to fix or even unrepairable PCB (delaminating of those tiny close pitch pins)!?

OK after listening to advice, just one last shot. So I cropped just the fractured pads area. I was saying it was poor res as I couldn’t zoom in to see the fine detail as I could with the original image. So I’ve effectively done the zooming my end so maybe now it looks clearer than it was on this forum, despite the reduced res.? |
