PCB Fabrication – ENIG, HASL, OSP Finishes

PCB Fabrication – ENIG, HASL, OSP Finishes

Overview

Surface finish selection is critical to PCB performance—affecting solderability, shelf life, wire bonding capability, and cost. Studio Electronics offers PCB Fabrication with ENIG, HASL, OSP, and other surface finishes to match your specific requirements. As a trusted provider of PCB assembly in China, we apply finishes with precise thickness control and uniformity verification—ENIG for fine-pitch and long shelf life, HASL for cost-effective through-hole, OSP for cost-effective flat surface, and more. Our complete turnkey service covers fabrication, component sourcing, assembly, and shipping.

Surface Finishes – Selection Guide
FinishDescriptionAdvantagesBest Applications
ENIGNi 3-5μm / Au 0.05-0.1μmExcellent solderability; fine-pitch compatible; long shelf life; flat surfaceFine-pitch SMT; high-reliability; long storage
HASL1-25μm solder coatingGood solderability; cost-effective; reworkableThrough-hole components; cost-sensitive applications
OSP0.2-0.5μm organic coatingCost-effective; flat surface; fine-pitch compatibleConsumer electronics; cost-sensitive; short shelf life
Immersion Silver0.1-0.3μm silver coatingExcellent for high-frequency; flat surface; cost-effectiveHigh-frequency; RF applications

Finish Application Process

  1. Stage 1: Surface Preparation – Cleaning and micro-etching to ensure optimal finish adhesion.

  2. Stage 2: Finish Application – Electroless or electrolytic processes applied with precise control—thickness monitoring through XRF analysis.

  3. Stage 3: Verification – XRF analysis verifies finish thickness; visual inspection confirms uniformity.

  4. Stage 4: Solderability Testing – Solderability testing (where required) confirms finish performance.
