PCB Assembly Service

HXD provides turnkey PCB assembly services from prototype development to high-volume production.

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.

Pre-Production Engineering

We start every PCB Assembly project with a complete understanding of your Gerber files, assembly data, BOM, component packages, and testing requirements — ensuring the right process, cost, and production plan from the beginning.

PCB Assembly Capabilities

Capabilities are evaluated against your actual component set, board construction, process controls and test plan during quotation.

Assembly technology SMT, through-hole and mixed-technology assembly

Component Capabilities Supporting fine-pitch components, BGAs, connectors, power devices, and mechanical parts.

Board complexity Handling rigid, flex, and rigid-flex PCB assemblies for different design and production requirements.

Process options Offering lead-free assembly, selective soldering, manual operations, and process control for specific applications.

Programming & test Programming, ICT/FCT support and customer-defined verification

Final Assembly Supporting cable installation, enclosure assembly, labeling, and box-build services for complete product delivery.

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.
