FR4 CEM-1 CEM-3 PCB Board Fabrication Strict Quality Control

Reliable PCB Fabrication – Strict Quality Control

Overview

Reliability is earned through rigorous quality control—not just claimed. Studio Electronics offers Reliable PCB Fabrication with strict quality control applied at every stage of production. As a trusted provider of PCB assembly in China, we combine advanced fabrication equipment with comprehensive inspection systems—AOI, X-Ray, electrical testing, and reliability laboratory—to ensure every board meets your specifications. From single-sided to 20-layer boards, from rigid to flexible designs, our strict quality control ensures reliable, consistent results for every order.

Strict Quality Control – Every Stage, Every Board
Quality CheckpointInspection MethodWhat We Verify
Incoming MaterialMaterial certification review; dimensional measurementCompliance with specifications; material quality
Imaging & EtchingAOI inspectionTrace integrity; pattern accuracy; no shorts/opens
LaminationX-Ray inspectionLayer alignment; registration accuracy

Surface Finish Options with Quality Verification
  • ENIG – ENIG thickness: Ni 3-5μm / Au 0.05-0.1μm; XRF analysis for thickness verification; excellent for fine-pitch SMT

  • HASL – HASL thickness: 1-25μm; solderability test; cost-effective for through-hole components

  • OSP – OSP thickness: 0.2-0.5μm; flat surface; cost-effective; suitable for low volume PCB assembly

  • Immersion Silver – Silver thickness: 0.1-0.3μm; excellent for high-frequency; flat surface

  • Immersion Tin – Tin thickness: 0.8-1.2μm; flat surface; good solderability; press-fit compatible

  • Gold Plating – Gold thickness: 0.8-1.5μm; excellent durability; wire bonding compatible

Why Strict Quality Control Matters
  • Reliability – Every board is 100% tested; no defects escape

  • Consistency – Controlled processes ensure consistent results

  • Traceability – Complete quality records for every board

  • Regulatory Support – Documented quality supports regulatory submissions

  • Low Volume Support – Same strict QC for low volume PCB assembly and volume orders

Studio delivers Reliable PCB Fabrication—strict quality control ensuring every board performs as designed.
