Icom-Scottech provides hybrid-technology assembly combining surface-mount technology (SMT) and through-hole technology (THT) to support products that require both high-density circuitry and mechanically robust interconnects. Hybrid builds are particularly suited to assemblies incorporating fine-pitch SMT devices alongside connectors, power components, relays and other leaded parts. We support prototype, pre-production and volume manufacture, and we manage the interaction between SMT and THT operations to deliver a consistent, repeatable build outcome.

Hybrid builds are undertaken using a controlled process sequence, typically completing SMT printing, placement and reflow prior to THT component insertion and soldering. Build documentation defines the assembly order, tooling and handling requirements, ensuring that reflowed SMT components are protected during subsequent operations such as wave soldering, or hand soldering. Where applicable, solder pallets, masking methods and fixture designs are employed to shield sensitive areas and to control solder contact. Thermal requirements are managed through defined temperature settings, dwell times and pre-heat profiles to achieve reliable hole fill and solder fillets without compromising adjacent SMT joints or thermally sensitive components.

Quality assurance is applied throughout the hybrid process, with inspection activities aligned to the build stage and technology used. SMT features may be verified using visual inspection and automated optical inspection (AOI), while THT joints are inspected for solder wetting, fillet formation and acceptability against IPC-aligned workmanship expectations and the customer specification. Any non-conformances are managed through controlled rework by trained personnel using documented methods to maintain product integrity. To support auditability and compliance, we maintain clear build records and, where specified, component and material traceability alongside revision and configuration control; assemblies can also be subjected to functional verification in accordance with customer documentation prior to integration or delivery.

This integrated approach enables Icom-Scottech to deliver hybrid assemblies that are mechanically robust, electrically reliable and ready for downstream integration activities such as conformal coating, box build and final product test. By controlling interfaces between SMT and THT operations, we reduce process variability, support predictable yields, and provide customers with a dependable manufacturing route for complex mixed-technology products.
