The sourcing platform buyers use to find verified PCBA contract manufacturers, indexed by process, inspection capability, and IPC certification. Free to start.
Finding the right PCBA contract manufacturer, one that can handle your component mix, volume, quality class, and NPI timeline, is one of the most consequential sourcing decisions an electronics team makes. TandemOne profiles verified PCB assembly suppliers by their assembly capabilities (SMT, through-hole, mixed), inspection methods (AOI, X-ray, ICT), IPC certification class, and industry experience, so buyers can evaluate real capability before they share a BOM. Send a Structured RFI on TandemOne and connect with PCBA suppliers already set up to build products like yours.
SMT line specs, selective soldering capability, component package minimums, and mixed technology experience are profiled so you know upfront what a supplier can and cannot build.
AOI, X-ray, ICT, and flying probe capability is captured in supplier profiles rather than discovered mid-qualification when your board complexity exceeds a shop's inspection capability.
Layer count, component package mix, IPC class requirement, BOM complexity, and expected volumes go into one inquiry so suppliers can respond with real DFM input and lead time estimates.
TandemOne is free for every buyer to use.
Hardware engineers and electronics procurement teams at OEMs, startups, and contract product developers who need a PCBA partner that can support NPI, provide DFM feedback, and scale into production without losing quality control.
