Electronics manufacturing.
People behind every board.
Since 2005, we have helped customers turn circuit designs into manufactured boards, tested assemblies and finished electronic products.
FLJ PCB is the PCB and PCBA manufacturing brand of Shenzhen Philifast Electron Co., Ltd., based in Shenzhen, China. We bring fabrication, component sourcing, assembly and engineering support together for customers in Europe, North America and beyond.

A manufacturing partner
for the whole build.
A PCB is one part of your product. The materials, components, firmware, inspection and assembly decisions around it matter just as much.
Philifast provides PCB fabrication and electronic manufacturing services for prototype builds, small batches and volume production. Our work covers bare circuit boards, surface-mount and through-hole assembly, component procurement, IC programming, PCBA testing, cable assemblies and final product assembly.
Our engineering and production teams work together to review manufacturing files, resolve assembly questions and establish the process for each build. Customers can start with a bare-board order, a turnkey PCBA project or a wider manufacturing package, with the scope defined around their product.
Established in Shenzhen in 2005, we have developed our manufacturing resources, engineering experience and supply-chain support over more than two decades. European and American markets are an important part of our international customer base.

manufacturing scope.
Choose the services your project needs. We connect board fabrication, material procurement and assembly so the handoffs are clear from the first inquiry.
PCB fabrication
Single- and double-sided FR4 boards, multilayer structures, HDI, flexible and rigid-flex circuits, RF boards, metal-core and ceramic PCBs. Material, stack-up and special-process requirements are reviewed against your design.
PCB manufacturing →PCB assembly
SMT, through-hole and mixed-technology builds, with component sourcing, incoming inspection, firmware programming and agreed testing. Turnkey and customer-supplied material options support different purchasing needs.
PCB assembly →Engineering & EMS
PCB design and layout support, manufacturing review, component sourcing, cable and wire harness work, and box build assembly. Share the drawings, interfaces and acceptance requirements for the complete product.
Engineering & EMS →Real production resources.
Practical process control.
Our assembly operation combines seven SMT lines with two DIP lines and two manual soldering lines, supported by inspection and testing equipment.


SMT production
Yamaha YRM20 placement equipment supports surface-mount assembly. Paste printing, placement and reflow settings are controlled as part of the production process.

First-article review
Inspection before the remainder of a build helps resolve component identity, orientation and assembly questions at the start of production.

Inspection & testing
SPI, AOI and X-ray support assembly inspection. ICT, functional and environmental tests are selected to meet the customer’s project requirements.

Engineering knowledge.
Shared responsibility.
Our 200+ professional team brings manufacturing, engineering and production-management experience to the work. These are the responsibilities that connect your inquiry with the finished build.
Engineering & manufacturing review
Review fabrication data, stack-up, assembly requirements and open technical questions. Resolve the manufacturing decisions before release.
Procurement & material control
Review the BOM, component availability and sourcing requirements. Coordinate incoming inspection and customer approval of proposed alternatives.
Production & process engineering
Prepare the assembly route, fixtures and soldering process. Coordinate SMT, through-hole, programming and final assembly tasks.
Quality & customer communication
Align inspection, test coverage and reports with the order. Keep engineering questions, build status and delivery requirements connected.
Moments Together
Behind our manufacturing work are people who discuss ideas, welcome customers and spend time together. A closer look at our team, factory visits and life beyond the production floor.

A team that grows together
Quality built into the work.
Evidence that fits your order.
Quality starts with the manufacturing inputs and continues through materials, assembly, programming and final testing. The acceptance plan belongs to the product you are building.
Our management systems
Philifast’s published credentials include ISO 9001, ISO 14001 and ISO 13485. The FLJ PCB website also lists IATF 16949 and ISO 45001. Together, these address quality, environmental, medical-device, automotive and occupational health and safety management within their applicable scopes.
For supplier qualification, request the current certificates and confirm the named entity, manufacturing site, validity and scope for your order.
Certifications & compliance →Board & assembly acceptance
Define the applicable IPC document, revision, class and drawing requirements in the order. PCB acceptance and assembled-board acceptance address different parts of the build.
UL & material requirements
FLJ PCB lists UL credentials. Confirm the applicable file and board construction for your project. RoHS and REACH material documentation should be specified separately.
Testing & production records
Agree inspection coverage, test procedures, firmware revisions and the report package before production. Additional aging, temperature, humidity or drop testing is arranged to the customer’s requirements.
Management-system certification and PCB recognition do not replace the approvals required for a finished medical, automotive or other regulated product.
Our quality control process →A clear route from your
files to a finished build.
We review the technical scope and materials before confirming the production plan. Delivery depends on the board construction, component availability and agreed tests.
- 01
Share the project
Send Gerber and drill data, the BOM and assembly files, quantities and desired delivery. Include product drawings for integration work.
- 02
Resolve the details
Review DFM questions, material availability, substitutions, tooling, programming and test needs. Confirm the quotation scope.
- 03
Release the build
Approve the manufacturing files and BOM revision. Agree inspection requirements and any first-article hold point.
- 04
Manufacture & verify
Fabricate, assemble, inspect and test to the agreed plan. Include programming and product assembly when specified.
- 05
Deliver & continue
Confirm outgoing records, packaging and delivery. Identify file, component or firmware changes before repeat production.
Supporting the people
building electronic products.
Engineers need useful manufacturing feedback. Purchasing teams need a clear supply scope. Production teams need builds they can accept and repeat.
Our PCB and PCBA work serves industrial equipment, communications, medical electronics, test and measurement, robotics, renewable energy and energy storage, automotive electronics, consumer products and LED lighting.
We support customers with different levels of manufacturing readiness—from a design entering its first assembly review to a production program with defined drawings, test procedures and procurement requirements. Application-specific materials, records and supplier approvals are part of the project discussion.

Company identity, service scope and what to prepare for your first conversation.
What is the relationship between FLJ PCB and Philifast?
FLJ PCB is the PCB and PCBA manufacturing brand used by Shenzhen Philifast Electron Co., Ltd. Philifast was established in 2005 and is based in Shenzhen, China.
Does FLJ PCB manufacture bare PCBs and assembled boards?
Yes. Our services include PCB fabrication, SMT and through-hole assembly, component sourcing, IC programming and PCBA testing. Cable assemblies and box build work can be included in a wider electronics manufacturing project.
Can you support prototypes and production orders?
We support prototype builds, custom small runs and volume production. The manufacturing route and delivery schedule are reviewed against the design, material availability, order quantity and testing requirements.
Which quality documents can we discuss for supplier approval?
Ask for current management-system certificates, applicable UL documentation and the inspection and test records required for your build. Specify the IPC acceptance requirements, material compliance documentation and any application-specific approvals in your inquiry.
What should we send with an inquiry?
For bare boards, send fabrication and drill files, board specifications, quantity and desired delivery. For assembly, add the BOM, placement data, assembly drawings, programming instructions and test requirements. Product integration also needs mechanical and wiring information.
