Hiya Guys i rarely post so please excuse me if i have posted this in the wrong department, but i was wondering whether or not it is worth desoldering the various electronic components from this Circuit Board to sell, whether infividual or bulk such as to reycycling companys for tantalum...

Many Thanks,

Selling tantalum capacitors for scrap may be viable, but you need a quantity supply not just one board.

Selling other components is a non-starter. Were they working when still attached to the board? Did they survive the de-soldering process?
There are some chips on there which look like BGA - difficult to get off the board and if they use solder balls then impossible (on an amateur basis) to regenerate the balls.

I certainly wouldn't (knowingly) buy reclaimed electronic parts at any price.

Hmmm well could you start me off by lettig me know whether any off these componenets have tantalum inside them, oh this is just one board out off a sky box, the boxes have at least 2 major boards and i have an additional 5 sky boxes, various models...

Would the chips be off any value? I have a decent heat gun if that helps,

Here are a few chips & components i removed beforehand1471697228339957155515.jpg 1471697250294-1775748859.jpg 1471697269972-1159621977.jpg

I can see nothing I can identifiy as tantalum. The attached shows four black rectangles which I believe are zener diodes (as their designation begins with ZD) but smd tantalum capacitors look rather like that and with a similar polarity stripe at one end. They would have desinations beginning with C.

Ok,i thank you for your assistance, so initally there is no point in desolderig the surfacd mount components as they are worth virtually nothing?

Did they work before you removed them? Even if they did do they still work? How do you plan to test them before you sell them? What would you do when your customer complains that they don't work?

I'm out!

So , the surface mount resistors/capacitors/transistors are worth virtualyy nothing and i shoildn't waste my time trying to desolder them?

In my experience, board components of greatest value are the mechanical components, including heatsinks, knobs, attachment hardware. When you need just one of, it is often hard to find. Power inductors have some value, particularly if labeled as many of yours are. Resistors and capacitors are worthless. Possible exceptions to that being high-wattage resistors and very low valued ones used for current monitoring.

As for IC's, I have collected a few but have never used any of them.

In answer to PB, a surplus store in Cleveland has surplus electronic components and many used transformers, power inductors, heat sinks and other mechanical stuff for sale.

C30, the crystal and the heat sinks.

Hello,

What is scrap for the one, can be of great value to others.
In some parts of the world scrap boards can be of great value to the user, as parts can be very hard to get.
