PCB Assembly Services – SMT/THT, AOI & X-Ray, Prototypes to Series

Using SMD (Surface Mounted Devices) and THT (Through-Hole Technology), we can manufacture a wide range of individual products for you.

At TPS Elektronik, we deliver end-to-end electronic manufacturing services (EMS)—from DFM and sourcing to electronic assembly, functional test, and box build. Whether you need fast PCB prototyping service, PCB prototype assembly service, or high volume PCB manufacturing with traceability, our lines handle SMT, THT assembly (through-hole), mixed technology, rigid-flex PCB assembly, and demanding BGA soldering service for medical, industrial, and consumer electronics.

What “PCB” and “PCBA” Mean (and Why It Matters)

PCB = the bare printed circuit board (no parts).
PCBA = PCB + components assembled (the finished electronic module).
PCBA meaning / PCB and PCBA / PCBA vs PCB: A PCBA is a working assembly; a PCB is just the substrate you populate.

Electronic manufacturing services meaning: an integrated service that covers design-for-manufacture, materials procurement, assembly, test, and logistics—often called contract manufacturing companies or “EMS providers.”
