01 / 07Product file review
Product file review
Gerber, BOM and STEP files define the project: PCB fabrication, component sourcing, assembly, enclosure and QC. Before production, we review completeness, compatibility and execution risks. These files connect design to manufacturing and clarify the work ahead. Missing or conflicting data puts the PCB, components and enclosure at risk from the start. This stage finalizes the product data before it reaches the production line.
02 / 07PCB fabrication
PCB fabrication
Gerber files become the bare PCB—the foundation for the product. Board thickness, surface finish, tolerances and fabrication quality must match the project's requirements. A thorough PCB review reduces assembly delays, rework and production errors. The layer stack and fabrication quality directly affect soldering and durability. A poorly specified board creates problems for assembly and enclosure fit. Accurate PCB fabrication gives the remaining stages a sound foundation.
03 / 07Component sourcing
Component sourcing
Components are selected, checked and sourced against the BOM, with each part matched to its footprint. We review availability, lead times, acceptable alternatives and critical component risks. Component selection is part of product quality control, beyond purchasing alone. Compatibility with the SMT line helps prevent assembly delays. Critical parts and their supply schedules need to be confirmed early. The aim is to deliver the right parts to the line without production surprises.
04 / 07PCB assembly (PCBA)
PCB assembly (PCBA)
Components are assembled onto the PCB, turning engineering files into a testable unit. SMT line quality, component polarity, solder paste, the reflow profile and assembly sequence all matter. Small assembly errors can affect testing, performance and delivery. Once the components are fitted, the PCB becomes a PCBA ready for functional testing. Controlled assembly produces a working unit that can move to the next stage.
05 / 07Enclosure fabrication
Enclosure fabrication
STEP files guide production of the enclosure, cover, chassis and other mechanical parts. The process—CNC machining, injection molding or 3D printing—depends on volume, material, lead time and required accuracy. FDM and SLA are common choices for rapid prototypes. At higher volumes, injection molding may offer consistent production, a better finish and lower unit costs. The enclosure must fit the PCB dimensions and connector locations.
06 / 07Production-line inspection
Production-line inspection
QC runs from PCB fabrication through assembly and enclosure production to shipment. It covers board quality, assembly quantities and workmanship, enclosure fit and suitable packaging. Where needed, X-Ray inspection, photos, sampling and reports reveal defects for correction on the line. QC results are recorded through advanced automation and remain traceable through shipment.
07 / 07Ready for delivery
Ready for delivery
After QC, the product moves to final packing, counting, labeling and shipment preparation. We check quantities, accompanying documents, appearance, packaging and shipping information. Projects involving multiple parts or suppliers also need order consolidation and logistics coordination. The output must be ready for delivery, verifiable and traceable. Incomplete counts or documents make it harder to verify the consolidated shipment at its destination.
