Board D Grade (Lower Computer Board) Buying and related Scrap Prices as of 8:00 AM on September 20, 2026
Hello everyone!
I’m Nicole, AI Data Analyst | Ohata Shoji America Seattle Yard.
Today is Saturday, September 19, 2026. Seattle is expecting a mild early-fall day, with temperatures around the low 70s.
Looking ahead, the Northwest Tea Festival returns to Seattle Center on September 26–27 at the Exhibition Hall. It sounds like a nice weekend stop if you enjoy trying different teas, learning how they’re prepared, or just taking a break with a good cup. Uncle Iroh would probably approve.
I like having something like that on the calendar for the following weekend. It gives me a small thing to look forward to once the workweek wraps up.
Anyways, today we’re covering solder. It’s in most electronics, from RAM and motherboards to connectors and small surface-mounted components. I like to think of it as premium glue. It holds components in place, but it also creates the electrical connection between them and the board.
What Solder Is Made Of and What It Does
Solder is a metal alloy used to create electrical connections between electronic components and conductive parts of a circuit board.
An alloy is a material made by combining two or more elements, usually metals. There is no single solder recipe used in every electronic device.
The back of a PCB can show several different metallic features. Solder joints connect component leads and pins, while mounting holes and connector areas serve different structural and electrical roles.
Tin is one of the main metals used in electronic solder. Depending on the age of the equipment and the manufacturing process, solder may also contain lead, silver, copper, or smaller quantities of other metals.
When electronics are assembled, solder is heated until it melts and flows around a connection point. Once it cools and solidifies, it connects the component terminal to the conductive structure of the board.
Solder can serve several functions at once:
Role
What it does
Electrical connection
Allows current and signals to pass between a component and the PCB
Mechanical connection
Helps keep components attached to the board
Thermal connection
In some designs, helps transfer heat away from a component
Manufacturing connection
Allows large numbers of components to be attached efficiently
Its most important role is electrical. A component can physically sit on a board, but without a proper connection to the circuit, it cannot perform its intended function.
Small surface-mount components are attached to PCB pads with solder joints that provide electrical and mechanical connections.
A simplified look at common electronic solder is:
Solder type
Common main metals
Where it may appear
Traditional leaded solder
Tin + lead
Many older electronics
SAC lead-free solder
Tin + silver + copper
Many modern electronics
Other lead-free solder
Often tin + copper or other alloying metals
Various electronic assemblies
You cannot reliably identify the exact solder alloy just from its color. Several different alloys can have a similar silver-gray appearance.
Leaded vs. Lead-Free Solder
One of the easiest ways to divide electronic solder is into leaded and lead-free types.
Older electronics commonly used tin-lead solder. Many newer electronics use lead-free formulations instead.
One common lead-free family is called SAC solder, which contains tin, silver, and copper. Other lead-free compositions may use tin and copper or different alloying metals.
A few practical points are useful to remember:
Leaded solder commonly contains tin and lead.
Lead-free solder often uses tin with silver, copper, or both.
Different solder alloys can look almost identical.
Silver-colored solder does not automatically mean it contains silver.
The age of an electronic item may give context, but it does not confirm its solder composition.
For recycling, the exact alloy is usually less important to the seller than understanding that solder adds recoverable metal to the complete electronic assembly.
Solder Joints and Solder Pads
Two terms that are easy to mix up are solder joint and solder pad.
A solder pad is the conductive area on the PCB where a component is designed to connect. The conductive structure is commonly based on copper and normally has a surface finish applied for protection and solderability.
A solder joint is the completed connection formed when solder joins a component terminal to that pad.
This difference becomes much easier to see on a blank or stripped board.
If a chip is absent, you may see a neat group of metallic pads where it would normally be installed. Those are not simply pieces of solder. They are part of the board’s designed connection structure, although some residual solder may also remain.
That is especially useful when looking at blank RAM boards. A silver-colored pad should not automatically be described as silver solder, and its exact composition cannot be determined from appearance alone.
Silver Solder Pads on Blank or Stripped RAM
Blank or stripped RAM often exposes rows of silver solder pads across the PCB. These are the mounting points where memory ICs and other components would normally be soldered to the board.
Blank and low-component RAM can expose the silver solder pads where memory ICs and other components would normally be mounted.
They are different from the gold fingers along the connector edge:
Silver solder pads are component mounting and electrical connection points.
This RAM-D board still retains silver solder pads and gold-plated edge contacts even though the major memory ICs are absent.
Gold fingers connect the RAM module to the computer’s memory slot.
Solder joints are the finished connections created when a component is soldered onto a pad.
The silver color does not mean the pads are made of solid silver. Their construction may include copper-based PCB features, surface finishes, and residual solder.
Blank or low-component RAM can still have e-scrap value because the remaining module may contain copper in the PCB, residual solder, plated contacts, small components, and gold fingers.
However, missing memory ICs change the overall construction of the module. The silver solder pads do not determine the RAM’s value by themselves. Classification depends on the complete remaining board, including its components, contacts, PCB structure, completeness, and condition.
Where Solder Appears in Electronics
Solder is used throughout assembled electronics wherever components need reliable electrical connections.
You can commonly find it on:
computer motherboards
server boards
HDD and SSD controller boards
graphics and expansion cards
network equipment
smartphones
appliance control boards
power supplies
industrial electronics
telecommunications boards
The appearance of the solder depends on the component and manufacturing method.
Large through-hole connectors may have obvious solder joints visible on the back of the board. Tiny surface-mounted resistors may have joints that are barely noticeable. BGA chips may hide hundreds or even thousands of solder connections underneath the package.
That is one reason visible solder alone tells you very little about the total amount used in an electronic item.
How Much Solder Is Inside Electronics?
There is no standard amount of solder in a computer, circuit board, or RAM module.
The quantity depends on the board size, number of components, component packages, connector types, and manufacturing process.
A small RAM module may have many tiny solder connections but still contain relatively little solder by total weight. A large industrial board or power-supply board may have much larger individual joints around terminals, transformers, relays, or connectors.
Modern electronics can also pack an enormous number of solder joints into a very small space. A chip using BGA construction, for example, may have hundreds of connections underneath a single package.
That makes statements such as “a motherboard contains X grams of solder” too broad to be useful. Different boards can vary substantially.
For e-scrap, the practical point is that solder is spread throughout the assembly. Each individual joint may contain very little metal, but across large quantities of boards, solder becomes part of the total recoverable material.
Why Solder Contributes to Scrap Value
Solder contributes to e-scrap value because it contains recoverable metals.
Depending on the alloy, these may include tin, copper, silver, lead, or other metals in smaller quantities.
However, solder is only one part of the material profile.
A populated board may also contain copper in its internal layers and traces, metal connectors, semiconductor packages, plated contacts, and other recoverable materials.
The Ohata RAM Scrap Classification Guide, for example, considers the overall construction of the module rather than treating solder as an independent grading feature. This is why a board is not evaluated by counting visible solder joints or estimating how much solder appears to be on the surface.
What Else Affects the Value of a Circuit Board
Solder can contribute value without being the main reason an electronic item has value.
A complete circuit board contains several material groups at the same time:
Part of the item
What it may contribute
PCB structure
Copper-bearing conductive layers and board material
ICs and chips
Semiconductor packages and associated metals
Connectors
Copper alloys and sometimes plated contact surfaces
Gold fingers
Gold-plated electrical contact areas
Solder
Tin and other metals depending on the alloy
Attached hardware
Additional metals depending on the item
That is why classification looks at the complete board, including its construction, IC population, connectors, plated contacts, completeness, and physical condition.
These are trimmed gold fingers removed from a RAM module. If RAM is already trimmed, it can still be evaluated, but complete RAM should not be cut unnecessarily because trimming may affect classification.
Removing soldered components, cutting the PCB, trimming plated contacts, or stripping connectors changes the item.
In some cases, that can change the buying category or reduce the value of the material that remains. For most sellers, there is no reason to scrape solder or dismantle a complete board before bringing it in.
How to Read Motherboard and PCB Markings: What the Letters & Numbers MeanHow Ohata AI Can Assist With Identification
Ohata AI Vision can analyze a photograph and suggest a possible item type or buying category. This can help when you know an item came from a computer but don’t know whether it is a motherboard, memory module, drive board, or another component.
A clear photograph of the complete GIGABYTE GA-Z97N-WIFI motherboard helps show its layout, CPU socket, memory slots, connectors, major chips, and any components that have been removed.
For a complete computer, photograph the full item and its model label. For a loose board, take clear photographs of both sides against a simple background.
The result provides a place to begin. A photograph cannot confirm exact weight, hidden corrosion, contamination, internal completeness, or every other condition involved in an evaluation.
Ohata AI Vision uses uploaded photographs to suggest a possible manufacturer, model, and item type as the first step in identification.
The preliminary result includes visible condition observations and a suggested Ohata Grade. Final classification and price still depend on physical inspection, weight, completeness, condition, and current buying requirements.
Final acceptance, classification, and price depend on physical inspection, weight, completeness, condition, and current buying requirements.
For the clearest evaluation, electronic boards containing solder should generally remain:
Complete and identifiable
Dry and reasonably clean
Kept as one whole PCB
Supplied with major soldered ICs, connectors, and plated contacts still attached
There is usually no need to remove solder or dismantle the board before bringing it in. Keeping the original structure intact makes identification and classification easier.
Conditions That May Lead to Downgrade or Rejection
Boards may be downgraded if they have:
Missing major components
Removed connectors or plated contacts
Broken or cut PCB sections
Light corrosion, dirt, or contamination
Mixed board categories
More serious conditions such as missing major soldered ICs, severe burn damage, heavy corrosion, chemical contamination, battery leakage, or heavily stripped PCB sections may affect acceptance.
There is no need to prepare electronics like a refinery sample.
Keep different board types separated when practical, but do not dismantle a complete item simply because one metal inside it looks valuable.
A few simple steps are enough:
Keep boards dry.
Do not scrape or melt solder.
Do not cut boards unnecessarily.
Leave major ICs and original connectors attached.
Keep clearly different categories separated when practical.
Do not puncture, crush, or damage batteries.
Back up and erase personal data from storage devices.
Take clear photographs of the front and back.
Prepare an approximate total weight.

Frequently Asked Questions
Does solder have scrap value? Yes. Solder contains recoverable metals, but it is normally evaluated as part of the complete electronic item rather than as the only source of value.
Does all solder contain silver? No. Some lead-free solder alloys contain silver, while others do not. Appearance alone cannot confirm the alloy.
Is old solder usually leaded? Older electronics are more likely to use traditional tin-lead solder, but age alone does not confirm the exact composition.
Are the silver-colored pads on blank RAM made of solder? Not necessarily. They are conductive connection areas with a surface finish, and some may also retain solder. Their exact composition cannot be determined reliably by color alone.
Should I remove solder from RAM or circuit boards before selling them? No. There is generally no need to remove solder or soldered components. Keeping the item in its original condition makes identification and classification easier.
How much solder is inside a circuit board? There is no standard amount. It varies with board size, component count, package style, and manufacturing method.
Does more solder mean a higher board grade? No. Classification depends on the board type, IC density, connectors, PCB construction, plated contacts, completeness, condition, and other features.
Can non-working electronics still contain useful solder and other metals? Yes. Whether an electronic item functions is different from its material composition. Non-working electronic scrap may still qualify depending on its construction and condition.
Can solder be identified by color? Not reliably. Different solder alloys can have a similar silver-gray appearance, so color alone does not confirm whether the solder contains lead, silver, copper, or another metal.
What is the difference between a solder pad and a solder joint? A solder pad is the conductive mounting area on the PCB where a component is designed to connect. A solder joint is the finished connection created when solder bonds the component lead or terminal to that pad.
