Established in Shenzhen in 2005, Shenzhen Philifast Electron Co., Ltd. brings PCB fabrication, assembly and downstream electronics services together. FLJ PCB is our manufacturing website, connecting customers worldwide with our engineering, purchasing and production teams.
Our board portfolio covers rigid and multilayer PCBs, HDI, flexible and rigid-flex boards, aluminum and copper-core constructions, ceramic and RF boards. We support prototypes, small production runs and repeat manufacturing for industrial, communications, medical, automotive, energy and consumer-electronics applications.
For PCBA, our production resources include seven SMT lines with Yamaha YRM20 equipment, two DIP lines, manual soldering and wave-soldering operations. SPI, AOI and X-ray inspection are combined with programming and agreed electrical or functional tests to support the build requirements.
Work with us for an individual service or a coordinated turnkey project—from design-file and BOM review to component supply, fabrication, assembly, cable integration and final packaging.
Quality begins with an agreed specification and continues through material control, assembly inspection, testing and release. The right evidence is part of the delivery.
01 / Before production
Review design files, BOM revisions and component availability. Resolve manufacturability questions and approve substitutions before release.
02 / During assembly
Use SPI, AOI and X-ray where appropriate to the package, solder joint and assembly process. Define the inspection route for your board.
03 / Before delivery
Set ICT and functional-test coverage, fixture requirements and pass/fail criteria. Agree the applicable IPC acceptance class and release records.
04 / Supporting your product
Request the relevant system certificates, material compliance information and project records. RoHS/REACH documentation is reviewed separately from factory certifications.
A manufacturing partnership works when responsibilities, specifications and delivery expectations stay clear.
Coordinate fabrication, purchasing and assembly through one project team instead of managing disconnected suppliers.
Review Gerber files, BOM details and manufacturability questions before releasing the approved revision for a build.
Review availability and purchasing options. Proposed substitutes require your approval before they are used.
Agree the inspection, test coverage and release records relevant to your application and production stage.
Keep design decisions, materials and quality requirements connected from the first review to final delivery.
Share PCB files, BOM, quantity, technical requirements and your target delivery date.
Confirm manufacturability, supply arrangement, pricing, lead time and test scope.
Release the agreed revision for fabrication, purchasing and assembly.
Complete the agreed inspections, programming and board-level tests.
Ship your finished build and prepare for follow-on production or engineering changes.
Thermal performance, signal integrity, reliability and traceability matter differently in every product. Start with the requirements that matter to yours.
Control boards, motor drives and connected equipment.
Assembly consistency, inspection and project documentation.
Robust builds, process control and application-specific review.
RF performance, controlled impedance and dense interconnects.
Thermal management, metal-core and heavy-copper boards.
Compact electronics from prototypes to repeatable production.

United States
Prototype PCB assembly
The assembly team flagged a connector-orientation question before production. Communication was clear, and the boards were ready for our prototype checks when they arrived.

Germany
PCB manufacturing
We appreciated the practical questions about the fabrication files and finish requirements. The boards matched the approved specification, and the technical updates were easy to follow.

United Kingdom
Turnkey PCBA
Having component sourcing and assembly coordinated by one team made the project easier to manage. The BOM questions and proposed alternatives were explained before we approved the build.

Italy
Repeat production
For our follow-on run, the team kept the revision and assembly requirements clear. Consistent communication helped us plan incoming inspection and the next production step.

Talk to our teamFor bare PCBs, send Gerber or ODB++ files, drill data, quantity, stack-up and fabrication requirements. For PCBA, add the BOM with manufacturer part numbers, placement data and assembly drawings. Include testing, firmware and enclosure requirements where applicable.
Yes. We coordinate PCB fabrication, component sourcing, assembly and agreed testing. Tell us whether you need full turnkey, partial turnkey or consigned assembly so material ownership and purchasing responsibilities are clear.
Yes. We support prototype verification, small runs and repeat production. Quantity, materials, component availability and the test plan determine the manufacturing route and confirmed delivery schedule.
We review the BOM and flag availability issues. Suggested alternatives are submitted for your approval before use, with purchasing and production aligned to the approved revision.
Our inspection and testing options include SPI, AOI, X-ray, ICT and functional testing. The appropriate combination, fixture requirements, coverage and reporting are agreed for your assembly rather than assumed to be identical for every order.
Expedited manufacturing and assembly can be reviewed for your project. Send your files, quantity and required delivery date; we confirm feasibility and lead time after engineering and material review.
