Server, Storage & Data Center Board Roles
Identify the Board Within the Server or Storage System
A server or storage platform can contain different boards for computing, control and interconnection. Identify the particular board so its stackup, interfaces and acceptance requirements can be defined.
Bare Boards Built to the Approved Package
PCBELEC reviews the submitted fabrication data and manufactures the agreed board construction, with inspection and delivery records defined for the order.

Stackup, Materials & Fabrication Inputs
Define the Stackup, Materials and Critical Interconnects
Give manufacturing review one consistent set of files, drawings and requirements. Define the stackup, material system and critical features before confirming the fabrication and verification scope.
Swipe horizontally if needed to view all fabrication requirements.
| Requirement Area | Information to Provide | Manufacturing Review Focus |

| Material System & Copper Profile | Named grades or approved alternatives, relevant Dk/Df data and test conditions, copper requirements and substitution restrictions. | The complete material definition, dielectric construction and any proposed change requiring customer approval. |
| Controlled Impedance | Targets, tolerances, single-ended or differential structures, relevant layers, reference planes and report requirements. | Material and geometry assumptions, test structures, coverage definition and the agreed verification method. |

| Mechanical & Connector Interfaces | Outline, datums, thickness, connector positions, finished-hole tolerances and any specified press-fit or edge-contact requirements. | Profile and alignment conditions, critical connection features and the measurement requirements needed for the manufactured board. |
Construction & Manufacturing Routes
Match the Construction to the Specified Design
Use the approved layout, stackup and mechanical requirements to define the fabrication route. Review materials, interconnects and process features as one construction rather than separate capability labels.
Swipe horizontally if needed to compare all manufacturing routes.
| Construction / Requirement | When to Evaluate | Review Together | Related Resource |
|---|---|---|---|
| Rigid & Multilayer | Motherboard, controller, interface or auxiliary designs with defined routing and reference layer requirements. | Material system, layer arrangement, dielectric thicknesses, copper, finished thickness and hole structure. |

Multilayer PCB → |
| HDI | Dense layouts specifying microvias, build-up interconnects or defined fine features. | Build-up sequence, dielectric compatibility, via spans, pad geometry, filling and acceptance requirements. | HDI PCB → |
| Specified Backplane / Thick-Board Features | Interconnection boards with specified thickness, connector arrays and mechanical interface conditions. | Finished holes, plating, connector alignment, drilling conditions and any specified press-fit or backdrilling features. | Manufacturing Capabilities → |
| Customer-Specified Materials & Special Constructions | Designs requiring a named laminate system, defined copper profile or other specified construction conditions. | Grade and property criteria, layer-by-layer construction, bonding and interconnect compatibility, with substitution restrictions clearly identified. |

Construction categories can overlap. Any flexible or rigid-flex connection regions should also be defined in the fabrication package where the design requires them.
Manufacturing Verification & Delivery Records
Connect Manufacturing Verification to the Approved Build
PCBELEC provides microsection reports with every order, offers 100% impedance testing and supports IPC Class 3 requirements. Define the evidence needed for the specified construction and accepted revision.
-
Microsection Reports for Every Order
Each order includes a microsection report. Identify any additional sample locations, measurements, acceptance limits or customer report-format requirements during inquiry.
-
100% Impedance Testing
Provide the specified targets, tolerances and structures. Confirm the test approach, coverage definition and required reporting against the approved stackup and acceptance criteria.
-
IPC Class 3 Support
Specify the governing board standard, revision, class and customer additions. Class 3 support does not mean every server or storage order defaults to Class 3.
Define the Records for the Features That Matter
Align inspection and verification requirements with the released drawing, stackup and fabrication data. Identify critical features, applicable limits and the records required for delivery.
-
Construction & Critical Dimensions
Define the features to inspect, including thickness, holes, connection geometry and any specified backdrill or interconnect conditions.
-
Impedance Structures & Reporting
Identify targets, tolerances, layers, reference structures, test coverage and the required result format.

Connect the board reference, revision, required markings and delivery records to the accepted manufacturing package.
-
Approved Changes & Deviations
Record accepted engineering answers, material alternatives and construction changes before manufacturing release.
Evaluation, Production & Change Control

Server & Storage PCB Manufacturing FAQ
Clarify the Requirements Before Fabrication
Practical answers about construction, materials, impedance, backdrilling and keeping manufacturing requirements consistent across builds.
Need a project-specific answer?
sales@pcbelec.comWhat types of PCBs are used in servers and storage systems?
A platform can contain motherboards, compute boards, storage controllers, backplanes, interface cards and auxiliary control boards. Their construction follows the particular circuit and mechanical requirements.
Identify the actual board and submit its fabrication package rather than using the equipment category as the complete specification.
Do all server PCBs require high layer counts or HDI?
No. The layer count and interconnect structure depend on the actual routing, references, packaging and connection requirements.
Where HDI is specified, define the build-up sequence, dielectric system, via spans, pad geometry and any filling or capping requirements.
Is high-Tg material the same as low-loss material?
No. Tg and electrical loss describe different material characteristics. A high-Tg label alone is not a complete low-loss material specification.
Provide the named grade or approved criteria, relevant Dk/Df data and test conditions, copper requirements and the intended dielectric construction.
What should be provided for controlled-impedance fabrication?
Provide targets and tolerances, single-ended or differential structures, relevant layers, reference planes and the approved material and stackup.
Confirm test structures, coverage and report requirements. Identify which proposed material, thickness or geometry changes need approval before release.
When should backdrilling be evaluated?
Evaluate it when the design specifies removal of unused plated-hole stub sections. It is not a default requirement for every server board.
Provide the drilling side, affected holes, target layers, tool requirements and permitted residual-stub or depth conditions, with the applicable verification criteria.
Does impedance testing establish channel or data-rate performance?
No. Impedance testing verifies the agreed impedance requirements under its defined method and coverage. It is not complete-channel or equipment performance validation.
Additional insertion-loss, return-loss, S-parameter or other measurements require a separately confirmed test object, structures, method, limits and responsibility.
How should material and stackup changes be controlled?
Define approved grades, stackup conditions and substitution restrictions in the fabrication package. State which changes need notification or customer approval.
Record accepted changes against the required revision and confirm any effect on geometry, interconnects, verification and delivery records before release.
Does PCBELEC supply bare boards or assembled server hardware?
PCBELEC focuses on custom bare PCB manufacturing, including agreed fabrication, inspection and delivery records. It does not supply off-the-shelf replacement motherboards or complete server systems.
Component sourcing, assembly and system-level validation are separate activities. For assembly inquiries, use the PCBJHY referral in the site footer.
