About SLLPCB：PCB Manufacturing and Assembly for Prototypes to Production

Our Story

SLLPCB has more than 20 years of experience in the PCB industry. Over the years, we have developed experience across PCB fabrication, advanced board technologies, component sourcing, PCB assembly, and production support.

Our goal has stayed simple: make PCB manufacturing easier for electronics companies that need reliable quality, clear communication, and flexible production support.

Today, SLLPCB supports projects from fast prototypes and small-volume builds to full-scale production. Our manufacturing and assembly capabilities allow us to handle both standard PCB requirements and complex designs that require HDI, high-frequency materials, rigid-flex structures, heavy copper, or other specialized technologies.

What We Do

SLLPCB provides a complete PCB and PCBA service chain, covering PCB fabrication, component sourcing, assembly, inspection, testing, and delivery.

PCB Manufacturing

We manufacture PCBs from prototypes to production, including single-sided, double-sided, and multilayer boards. Our capabilities extend to advanced technologies such as HDI, high-frequency, rigid-flex, flexible, heavy copper, and metal core PCBs.

PCB Assembly

Our turnkey PCBA service covers component sourcing, SMT assembly, THT assembly, soldering, inspection, testing, and final delivery. Customers can use full turnkey, kitted, or hybrid procurement models based on project requirements.

Engineering Support

Our engineering team supports DFM review, design feasibility checks, material selection, stackup review, and manufacturing requirement analysis before production.

Component Sourcing

We support BOM sourcing and component procurement as part of our turnkey PCB assembly service, helping customers manage PCB fabrication, components, and assembly through one production workflow.
