Frequently Asked Questions

1.Why choose DIP/Manual soldering over pure SMT?

While SMT is efficient for miniaturization, Through-Hole (DIP) components offer superior mechanical strength for parts like connectors, transformers, and power transistors. Manual soldering is essential for components that cannot withstand the high temperatures of reflow or wave soldering ovens.

2.How does Omini PCBA ensure solder joint quality?

We utilize multi-stage quality control including Automated Optical Inspection (AOI), X-Ray for hidden joints, and highly trained IPC-certified technicians for manual touch-ups. Every board undergoes a final functional test.

3.Can you handle complex board designs with both SMT and THT?

Yes, Omini PCBA specializes in Mixed-Technology Assembly. We typically use SMT for density and THT/Manual soldering for high-stress or heat-sensitive components on the same board.

4.Does Omini PCBA provide full turnkey services for DIP assembly?

Absolutely. We offer full turnkey solutions including PCB fabrication, component procurement, THT assembly, testing, and final packaging. Our procurement team works with verified global distributors to ensure authentic, high-quality parts for your project.
