Electronic intelligent products in various fields rely on the mature process of PCBA, which consists of PCB manufacturing and PCB assembly.

1.What is PCBA? 
PCBA stands for Printed Circuit Board Assembly. It involves using SMT and other processes to assembly components on a PCB board and then goes through the DIP plug-in process.

2.Some Technologies on Circuit Card Assembly

THT (Through-Hole Technology): Electronic components are install though the holes of the PCB. It commonly happens when it comes to small batches and prototyping.

SMT (Surface-Mount Technology): Electronic components are placed and attached directly on the surface of the PCB, which easily allows for automation. This method is widely used and suitable for mass- production.

Hybrid Technology: Not all components can be completed by relying on a single technology. Some special components require flexible use of the characteristics of the above two assembly methods to achieve a balance between cost and mass production.

3.The Process of Making Printed Circuit Assembly

For THT technology: Sourcing components; Making PCB board; Inserting components; Wave soldering; Visual inspection; In-circuit testing; Functional testing; Packaging.

For SMT technology: Purchasing components; Making PCB board; Soldering paste printing; Picking and placing; Reflowing soldering; Visual inspection; In-circuit testing; Functional testing; Packaging.

For hybrid technology: Purchasing components; Preparing the manufactured bare board; Soldering paste printing; Picking and placing; Reflow soldering; Manually insert components; Wave soldering; Visual inspection; In-circuit testing; Functional testing; Packaging.

A complete printed circuit board assembly process includes PCB manufacturing, component procurement, and pcb board assembly. Choosing an experienced pcb and assembly manufacturer can advance your project schedule and get your product to market faster!
