Procurement Technical Guide

Frequently Asked Questions: Multilayer PCBA Sourcing

Direct technical answers addressing layer tolerances, component verification, stack-up design, and quality governance.

How do you maintain signal integrity on high-speed multilayer boards?

We execute strict stackup modeling using polar Si9000 calculators to maintain controlled differential and single-ended impedance within ±5%. Solid continuous reference ground planes are allocated below critical high-speed trace layers to eliminate crosstalk and signal degradation.

What is the protocol for verifying hidden solder joints on BGA and QFN packages?

Every multilayer board featuring BGA, LGA, or bottom-terminated components undergoes transmission X-ray inspection. Our automated X-ray inspection (AXI) confirms ball alignment, bridging absence, and measures solder voiding against IPC-A-610 Class 3 thresholds (<15% total voiding).

How are moisture sensitivity levels (MSL) handled for multilayer assemblies?

All ICs and sensitive passive components are managed in an ESD-protected cleanroom equipped with desiccant dry storage cabinets maintained under 5% relative humidity. Components exceeding floor life limits undergo de-baking cycles per J-STD-033C before thermal reflow.

Can Aozite support customized Functional Testing (FCT) and firmware loading?

Yes. Our in-house test engineers fabricate custom bed-of-nails pogo fixtures, develop custom LabVIEW/Python test sequences, program microcontrollers directly during line flow, and log individualized serial-level performance logs for complete delivery accountability.
