Hi,

Would these old phone boards go into High Peripheral or would they fall to Low Peripheral?

Thanks.

High Peripheral.
You have no heavy junk. I would remove L1. Also the 2 electrolytic capacitors located to the upper right of L1.
You have plenty of MLCCs capacitors. Looks like gold contacts in the 2 connectors. Just enough ICs.
You squeak just in at High Peripheral.

IMO its a toss up, its close to high peripheral but not quite, not quite low peripheral ether. I would send it in as high peripheral myself.


Not all MLCCs are equal, if the board is late 90s or newer the MLCCs could be a lower grade. With that 97 date stamp it very well could be using the newer lower grade MLCCs. I think shark has a good video on MLCCs that goes over the differences.

I only mentioned the MLCCs with the rational. That the presence of MLCCs was better than none at all. It is still a close call between High or Low Peripheral. I did see the video that was mentioned.

I'd try and send it as High peripheral, but am expecting it to get knocked down due to the lack of gold.

If the phones have LCD screens however, the display driver boards tend to put on a pretty good show between visible gold and driver chips, but I didn't see you post any lcd driver boards, just the main board.

On the fence as well. I would probably send in as is but tough to put in Low/High as that is borderline. As others have commented I would probably put in High Peripheral as well.
