This page covers bare-board PCB fabrication: material, layer structure, impedance, fabrication tolerances, electrical testing, and the release package. Assembly is a separate scope because it adds component sourcing, placement, soldering, inspection, and board-level test.
Use this PCB manufacturing service for rigid, flex, rigid-flex, HDI, high-frequency, multilayer, and metal-core fabrication. Send Gerber or ODB++ data, stackup intent, material requirements, quantity, and electrical-test needs.
PCB prototype fabricationFor SMT, through-hole, or mixed-technology builds, use the assembly service page. Include the BOM, placement file, assembly drawing, revision, test intent, and who owns component sourcing.
PCB assembly servicesA complete fabrication package lets engineering confirm capability, testing, production controls, and schedule before release.
If part of the package is still open, identify the missing decisions. Engineering will confirm the remaining requirements during quotation.
As a PCB fabrication partner, we support rigid, flex, HDI, RF, rigid-flex, and metal-core constructions from prototype through production. If assembly is required, engineering confirms that scope separately during review.
Rigid PCB fabrication for single-layer through 64-layer multilayer configurations, including high-speed FR4, Rogers materials, and rapid prototype builds.
Advanced flexible PCB manufacturing using polyimide and specialty materials with superior bend reliability for dynamic applications.
High-density interconnect PCBs with advanced microvia technology for complex, miniaturized electronic devices requiring high component density.
Specialized high-frequency PCBs using premium materials with precise impedance control for optimal signal integrity in wireless applications.
Integrated rigid and flexible circuit boards that combine the benefits of both technologies for applications requiring reliability in dynamic environments.
Thermal management PCBs with aluminum or copper core for efficient heat dissipation in high-power applications like LED lighting and power converters.
Our pcb board fabrication and assembly release path keeps design decisions, production controls, test scope, and buyer approvals visible from quotation through shipment.
Engineering reviews fabrication data, stackup, materials, quantities, and documentation requirements before confirming the quote.
Open questions on manufacturability, impedance, panelization, tolerances, and materials are resolved before production release.
The agreed stackup, production notes, test scope, schedule, and any controlled deviations are recorded for approval.
Boards move through the approved process flow with in-process inspection and the electrical test scope defined for the order.
Required inspection records, conformity documents, material reports, and traceability data are prepared with the shipment.
Choose the review path by the board risk, then confirm the released construction and evidence package in the quotation.
High layer counts, low-loss materials, controlled impedance, backdrill and thermal structures are reviewed together. The RFQ should define the stackup, reference planes, drill transitions, impedance coupons, electrical test and any required inspection records.
Power converters, industrial drives and automotive power stages may need heavy copper, high-Tg or metal-core construction. Engineering checks copper balance, thermal paths, finished thickness, plating, temperature-rise targets and electrical-test scope before release.
RF front ends, antenna boards and wireless infrastructure need material, transmission-line, via-transition and launch decisions aligned. The quote can define impedance coupons, TDR or VNA scope, fixtures, calibration and application-specific acceptance limits.
Start with the process overview before defining the manufacturing scope: PCB manufacturing basics
Our facility operates two specialized manufacturing processes for different geometry windows. The positive process achieves industry-leading 2/2mil capabilities, while the negative process supports reliable 3/3mil precision builds.
Advanced alkaline etching with photoresist tenting technology delivers industry-leading precision for high-density interconnect applications.
Proven acid etching with advanced dry film methodology delivers reliable precision for standard applications and power electronics.
Use these values for initial screening. Final capability is confirmed against the complete material, stackup, geometry, finish, tolerance, and test combination.
