Any ideas? I tried adding a little heat but did not let go I don't want to break it the "board" seems thinner than usual and definitely is made out of different material there are 2 silver colored bars also that appear to be connected to board and possibly the aluminum it is attached too? Again I am a total newbie and if this is really easy and I'm missing it I apologize and it may not be wort my trouble to remove them. Thanks for any help and grading.

This one is borderline. You may get small socket for it but it's probably going to be peripheral unless you have a lot of them.


The big one is the same as the first picture. It's borderline but again probably peripheral. The smaller one depending on the back is atleast midgrade


Midgrade

Midgrade

Leave everything in for telco, remove everything for midgrade and ICs

Peripheral with chips in, midgrade with chips out. Leave them in here.

Peripheral; you can remove the three quads for IC rate on them

Both midgrade, the shell isn't coming off easily. Dealt with those before. Just give up and move on, it's midgrade either way.
The shell is probably a cast manganese which is in the 10-25 cent range so you're not loosing anything.

Lostinlodos thank you again for your help I'm sure it can get a little time consuming but you are doing a great service to help newcomers like myself and it makes a lot less intimidating when you have someone willing to help thanks.

When you start pulling (or buying-receiving etc) parts from non computer electronics you'll start running into all sorts of class benders, things that don't make sense from a tech standpoint, etc. Cable/satellite set top boxes are the worst to classify.
If I'm not sure I'll always tell you, and often another mod or MLS can weigh in and help out from their experience as well but occasionally there's boards who's class is ultimately dependent on the person who actually weighs your order on reception. You've got a few in this list.

Oh, and that support shell frame is usually attached with a nickel tin solder to stainless pegs, or has an enamel glue if it's sitting directly on the board. If it's zinc it's almost always marked; z in a triangle, or zn in a circle. And zinc is more valuable than the board and worth breaking the board over.

Otherwise you'll be loosing money (in time) removing it for much of any reason.

OK well I have at least 15-20 now and more coming of said boards would it be worthwhile to get pictures and email chris to get the most out of them? Here is a pic of one I pulled today I definitely would like to get more than peripheral out of them if possible. I also have a bunch of these boards with Lil screens is there any value or extra value in theses.

The displays will go as peripheral. I've sent a few like that before. There's a lot of non valuable weight in the display casing.

The next two boards are telco (as long as nothing strange and heavy on the backs). Good IC population and density.

I apologize if I missed it in your first post but I started to attempt to remove that board from carrier and it is weird the board itself is flexible however it appears that the bottom of board is coated in a metal there are poles but the board is not attached to them just circuitry. I looked for a z or zn but do not see one 422 A is on side of carrier hopefully the picture gives you enough detail

The boards are a combination of waste or recovery wood and plastic with metal inlay. Basically a plastic wood soup with glue. When you snap them it will look like very high raid mounting board or wood wall board. A good (safe) wack in the upside down middle with a hard object ought to simply break it enough to remove the board. Just use common sense they make sharp slivers and splinters.


A wild guess, but A may stand for aluminium.
