Welcome to Boardsort™ - Learn - Sell - Profit -

I'm glad I could help. There is a lot to learn and as I learn more I could probably update that particular response.

For instance, the IC chips, as rdw said, have varied value based on individual chips. That's why a 386 gold cap chip (essentially an IC chip) has more value than a green fiber chip. Then even within an individual class there is some variation. Lost can look at individual IC chips and know fairly accurately what the value is, I can't, yet.

In the mean time I try and trust my gut and the experience of others on the forum. The particular boards you circled ICs on I would probably throw in midgrade myself but that doesn't mean some or all aren't at low peripheral. If you want a definite answer send pictures of the questionable ones to Chris and then when he responds let us know too.

I am wondering if I am not understanding his question. Part of the problem I think is the fact I am not the best at explaining things either :)

I was trying not to do any grading for awhile...but I'm 99% sure on these specifically :D

Red should be CD/DVD (since can't see the backs on Picture A can't be positive)

Blue High peripheral

group B top right looking at that one again it does look like a DVD
the other one you have in red I'm not sure what is off of.

group A "the board with "TEAC" may very well be CD, the other one I am not sure what its off of.

the reason I think low peripheral on the boards you have circled in blue with the exception of the top left board is because of the lack of population.

my best suggestion to anyone that does not have a electronics back ground and can recognize DVD/CD drive boards right away. when you pull it off the drive keep it separated from any thing else.

DVD/CD drive boards have shrunk in size over the years, the smaller they get the harder they are to identify.

I feel like at some point in the future the newer and smaller DVD/CD boards will fall to peripheral. As of right now the major value in DVD/CD boards is the heavy gold plating on the pins. Same reason brown 3-1/2 floppy drive boards will go high peripheral.

All useful information and as far as brown boards rdw, I'm glad you posted that about the mouse boards and drive boards because I just let go of a handful as low grade boards, because the closest electronic scrap yard only accepts basically low, medium, high, and motherboards, with one or two classes in between.(It was just a test run to see how they do things so I could know where to draw the line of what to ship and what to hand deliver depending on shipping costs). Glad you saw those connectors as well marked, I still have a very hard time noticing those in pictures and grading pictures to myself before I read the responses is how I've been probably learning the most.
This will take me a bit of space but I will try and go back through what I was saying.

First off the only boards I brought up were the boards in group B because I agreed on everything I knew about and honestly I didn't really go through group A, first glance I pretty well agreed.
In group B the only board I disagreed on at all really was the second from the top on the left side. I counted 4 IC's(yes, low value) but I'll refer to ccussins post here about the "word of advice" from Chris(it's nearly at the bottom of the page):
https://boardsort.com/escrapforum/viewtopic.php?f=4&t=20857
Also the picture of ccussins board #3 in group 14 page 2 that shows a board with one lower value IC, and yes gold connectors but to me it had weight and extra space that the board in this posts group B didn't have(not sure I'm right but was looking at weight ratio myself):
viewtopic.php?f=4&t=20857&start=10

The others I mentioned were more me wondering and discussing.

With all of that in mind I also looked at the 3rd and 4th boards from the top on the left side in group B and saw two IC's on them but to me the ratio was off a bit much so I said borderline high peripheral in optimism but wasn't really disagreeing just saying the highest I thought it could possibly find it's way to I suppose and felt more comfortable with low peripheral(though I didn't state it).

The last board I pointed out was the bottom right board in group B was just to see if it could go low peripheral because of the IC and what effect the connector might have if a gold connector. None of which I was sure of, just discussing.

I myself do have a limited amount of electrical background and being around metals, but it was always the function of the components, never the makeup so I do realize that larger IC's have much more value and different components have different grades of material they are made of, I just don't have much knowledge at all about their specifics. I would also say that setting aside your boards like you said rdw when you take the drive apart is well-advised and a part of efficient sorting, basically touch the board as few times as possible. I also struggle to know when the plating is heavier or thinner so I guess I also more or less disregard the connectors at times because I don't really know yet how to consider them(unless they are very obvious, struggle more with USB, network, and RCA), I left a lot of connectors on the cables I last took off because I'm just not sure yet how to tell which connectors are actually gold plated(gold plating looks different at different thicknesses) and which ones are brass. I don't want to include something I don't understand at all.

My reply is very long I know but trying to address everything at once.

Marked, I feel that about all one can do is go with their gut and just be honest with those we are sending things to, maybe even put the ones we don't feel sure about in their own separation along with the category we think they go in, including a note explaining. That's about what I have come to as the best way for myself I can do things moving forward anyway. Also, I would possibly put the boards I was more wondering about in mid grade and at best low peripheral if it was mine.
So for whatever I've said, it's just how I kind of saw things(albeit from an inexperienced recycling stand point) from what I have looked through and the information I have gathered(small as it may be). Either way it's to be taken with a grain of salt for whatever it's worth.
*Edit* I should also say that I am glad to be corrected when I am looking at something wrong, so now that I've relaid out what I've said it may be easier to correct if I'm looking at things in the wrong light.

SamW,

Depending on how much you are planning to ship at one time. On smaller amounts of boards this will be easier for you and Boardsort.
lets just say:
You have 5 lbs of board "A" all just like and you aren't 100% sure its low or high peripheral but you are leaning high.
You have 10 lbs of boards you are absolutely sure they are high peripheral.
When you create your invoice go ahead and put 15 lbs on it. Keep the 5 lbs of boards separated from your 10 lbs and stick a note in with the 5 lbs asking them to verify the grade and let them know you have them on the invoice as high peripheral. Also email Chris directly with your invoice and let him know a well.

Its very difficult for me to do this on peripheral grade boards since I ship 500lbs or more at a time. I have shipped them some boards a year or so ago I thought they would go as automotive board Lost agreed on automotive boards.
I had no reason what so ever to question them being not automotive boards because of the heavy sealant on them to my surprise Chris emailed me and let me know they were cutting me a check "and by the way those boards you considered automotive boards were actually telco". The boards I sent in were SCADA boards which is covered in a heavy clear sealant to keep moisture out.

Boardsort will help you as long as you are honest with them.
Chris graded some boards for me 2 or 3 weeks ago, I wasn't sure why he graded them like he did so I asked why is this board high peripheral and this one high telco. He made an honest mistake my guess is because he was in a hurry and bad pictures. The one he said was high peripheral should have been low telco, the one he said was high telco is really borderline high peripheral / low telco.
But he said he would honor the boards that are border line as high telco. But I am not going to accept that, once I get them ready to ship I will put them on the invoice as low telco and separate them from the other low telco boards and ask them to double check them and move up or down a grade as needed. Chris has been more than fair and honest with me over the past years.

From going through several of these with Lost I'm fairly confident on the CD boards. I did qualify the group A boards don't show the back so may not be.

Did I miss something on trackpads? They all have ICs/bump ICs so those should be high peripheral.

Marked,
I may be wrong, but I don't see one IC chip making high peripheral. Like that brown board I posted it has 7 IC chips on it even pulling the junk off, it wont make low peripheral. Like I said i may very well be wrong on those and at the end of the day my opinion, your opinion, SAMW’s opinion the Jolly Green Giants opinion doesn't matter. The only opinion that matters is Chris and the gang at Boardsort.

Ccussins said high peripheral here

Not trying to make the thread any longer just acknowledging what was said.

rdw, I appreciate the layout idea for shipping into boardsort. That's about as close as I could have described what I was thinking for myself. I am also glad to know that Boardsort takes time to upgrade things when there is an apparent difference in the board grade. I don't really know the amount of each grade I will be sending in just yet but I will keep those things in mind, and it seems that thought the discussion might have drawn on a bit long, we were indeed discussing Boardsort's view of what these boards might be. Which is all that matters, like you say.

Marked, I am glad you noticed that, I wondered a bit about what it was, but had no way to know what it was for sure, haven't been that far into laptops yet. That will be useful information for later on.
