Prototype PCB Assembly
Fast and reliable prototype assembly services to validate designs before full-scale production.
Low-Volume PCB Assembly
Flexible low-volume PCBA solutions for startups, engineering teams, and small production runs.
SMT Assembly
Surface-mounted components placed directly onto PCB surfaces.
THT Assembly
Through-hole components inserted into PCB holes and soldered.
The Quick-Turn PCB Assembly Process
HXD manages the process from design files to assembled boards. Most PCB board assembly projects follow the steps below.
1. Design and File Review
Submit your Gerber files, bill of materials (BOM), and pick-and-place files. Engineers use automated checks and manual reviews to assess manufacturability. The review identifies potential fabrication and assembly issues before production begins.
2. PCB Fabrication and Stencil Production
The factory produces the bare PCBs and SMT stencil in parallel. This reduces waiting time and prepares both for assembly.
3. Component Sourcing and Preparation
HXD stocks common SMT components, including resistors and capacitors. Customers can choose between two service options:
Turnkey PCB assembly: HXD sources the components and manages assembly.
Consigned PCB assembly: Customers supply the components, and HXD assembles the boards.
4. SMT and Through-Hole Assembly
SMT equipment places surface-mount components on the boards. The team also completes through-hole assembly and soldering where the design requires it.
5. Inspection and Testing
The inspection plan follows the board design and agreed quality requirements. Checks include:
AOI to inspect component placement and visible solder joints;
X-ray inspection for hidden solder joints, including BGA and relevant QFN connections;
Functional circuit testing (FCT), when required by the project HXD inspects assemblies against the agreed IPC-A-610 acceptance criteria.

Inspection & Testing
Inspection coverage is planned around the component mix, joint visibility and functional requirement—not reduced to a generic checklist.
Incoming & pre-line checks
Material condition, identity, quantity and build-package readiness are checked before production release.
Process inspection
First-article and in-process checkpoints verify setup, polarity, placement and workmanship against the released data.
AOI and joint verification
AOI, visual review and additional methods are selected according to package geometry and visibility.
Electrical & functional testing
Customer-defined programming, ICT or FCT requirements are incorporated into the agreed manufacturing plan.
