CPU-B Grade (Ceramic CPU with Metal Plate & BGA Chip with Gold Tab)

What is CPU-B Grade

CPU-B is an official processor category in the Ohata CPU Classification System. It includes two package types with similar recycling characteristics:

• Ceramic CPUs fitted with a metal heat spreader

• Large BGA (Ball Grid Array) processor packages with visible gold tabs

Although these devices are used in different electronic equipment, they are grouped together because of their package construction and recoverable material profile rather than their processor model, computing performance, or manufacturer.

How to Identify CPU-B Processors

Correct identification begins with the physical package rather than the processor model.

CPU-B processors usually fall into one of two categories:

Ceramic CPU with Metal Plate

These processors use a ceramic package fitted with an aluminum or other metal heat plate. The ceramic body provides mechanical strength while the metal plate improves heat dissipation.

Large BGA Chip with Gold Tab

Large BGA semiconductor packages belonging to CPU-B can often be identified by their square package shape and one or more visible gold tabs along the package edge. Unlike standard plastic BGA devices, these gold tabs are one of the key visual characteristics used during classification.

Because processor families may look similar, final classification is always based on the complete package rather than a single feature.

Typical CPU-B Components

CPU-B includes a variety of processor and semiconductor packages commonly recovered during electronics recycling.

Examples include:

• Ceramic CPUs with aluminum or metal heat plates

• Large BGA processor packages with visible gold tabs

• Professional computing processors

• Enterprise processor modules

• Industrial processor packages

• Communication processors

• Specialized embedded processors

• Other processors meeting the Ohata CPU-B classification requirements

Processor family names are provided only as general examples. Final classification is always determined through physical inspection of the processor package rather than by manufacturer, processor model, or advertised specifications.

Common Sources of CPU-B Processors

CPU-B processors are commonly recovered from a wide range of electronic equipment, including:

• Desktop computers

• Enterprise servers

• Professional workstations

• Telecommunications equipment

• Industrial control systems

• Networking hardware

• Embedded electronic systems

Because these systems often contain higher-quality processor packages designed for long-term reliability, CPU-B components continue to enter the recycling stream even after many years of service.

Why CPU-B Processors Have Recycling Value

The recycling value of CPU-B processors is determined by the recoverable materials distributed throughout the complete processor package rather than by any single visible feature.

Recoverable materials commonly include:

• Gold

• Copper

• Silver

• Nickel

• Palladium

• Aluminum

• Silicon

• Gold bonding wires

Although CPU-B processors generally contain less visible gold than premium ceramic CPU grades, they remain valuable because of their engineered package construction and the concentration of recoverable materials contained within each device.

Consequently, physical construction provides a more reliable indicator of recycling value than processor brand, computing performance, or original market price.

Buying Standards

Higher purchasing values are generally offered for CPU-B processors that are:

• Complete and unmodified

• Clean and dry

• Free from excessive corrosion

• Free from glue, epoxy, or heavy contamination

• Properly sorted as CPU-B only

• Removed from heatsinks, motherboard sections, and unrelated electronic scrap

Processors mixed with other CPU grades, damaged semiconductor packages, broken ceramic processors, or miscellaneous electronic scrap may require additional sorting and may receive a lower purchasing value.

Proper sorting before delivery helps improve inspection efficiency and supports accurate classification under the Ohata CPU Classification System.

Ohata Inspection Process

Every shipment is inspected before the final purchasing price is confirmed. Our inspection focuses on:

• Package construction

• Completeness

• Physical condition

• Cleanliness

• Sorting quality

• Recoverable material profile

Processor manufacturer, processor generation, clock speed, and original retail value are not the primary classification factors.

Official Ohata CPU-B Classification Statement

A processor or semiconductor device may be officially classified as CPU-B Grade when its package construction, recoverable material profile, completeness, and physical condition satisfy the requirements of the Ohata CPU Classification System.

CPU-B primarily includes ceramic CPUs with metal plates and large BGA chips with visible gold tabs. Final classification is confirmed after physical inspection.

Ready to Sell CPU-B Processors in Richmond?

Once you believe your processors match the CPU-B characteristics, you don’t need to confirm the final grade yourself. The next step is simply to check the current buying information, keep the processors intact and prepare them for inspection.

STEP 1 – Check Today’s Buying Prices and Sort Your Materials

Before visiting our Richmond yard, please review the latest Canadian e-scrap buying prices and identification guides in the Ohata Scrap Wiki.

You can also use Ohata.AI Vision 1.0 Beta 1.0 to investigate an unfamiliar circuit board. Upload a clear photograph, and the tool can analyze visible features, such as the board’s shape, CPU socket, integrated circuits, connectors and component layout, to suggest what type of board it may be.

Buying prices and conditions may change with the market, so checking the applicable item page before you leave can help you understand how your material should be prepared.

Whenever practical, separate your e-scrap into groups such as:

• Computer motherboards

• Hard drives and HDD controller boards

• Server boards

• Laptop motherboards and logic boards

• Telecommunications boards

• CPUs and memory modules

• Power supplies and cables

• Other or uncertain electronic scrap

You don’t need to assign every item a final grade yourself. If something is unfamiliar, keep it in an “uncertain” group and use Ohata.AI for a preliminary photo-based identification.

Walk-ins are welcome during regular business hours, and no appointment is required for most ordinary drop-offs.

If you have a large commercial load, palletized shipment or an unusual type of material, please contact the Richmond team before visiting so we can prepare for your arrival.

STEP 2 – Bring Your E-Scrap and Valid Government-Issued Photo ID

Please bring your electronic scrap together with a valid government-issued photo ID.

Examples may include:

• British Columbia Driver’s Licence

• BC Identification Card

• BC Services Card with photo

• Canadian passport

• Permanent Resident Card

• Other valid government-issued photo identification

Business sellers may also be asked to provide company information or supporting documentation when applicable.

Clearly separated and labelled material is usually quicker to inspect. If possible, prepare the approximate weight and quantity for each group before visiting.

Please also remember that computers, servers, hard drives and solid-state drives may contain personal or business information. Back up anything you need and follow your own data-security requirements before the equipment leaves your control.

STEP 3 – Visit Our Richmond E-Scrap Buying Yard

Our Richmond yard is located at 11220 Voyageur Way, Unit 7, Richmond, BC, V6X 3E1. Before leaving, you can check the route and current traffic information through Google Maps.
