Why Choose Tin-Lead Plating?
Tin-lead finishes minimize intermetallic growth and solder cracking—ensuring predictable, durable solder connections over time.
Lead significantly reduces the risk of tin whisker formation, which can lead to shorts and latent failures in high-reliability systems.
We plate tin-lead for aerospace, military, medical, and other sectors where lead use is legally exempt due to its critical performance role.
Lead improves plating ductility and helps prevent cracking under extreme temperature swings—ideal for avionics, satellites, and outdoor electronics.
With over five decades of field data, tin-lead remains one of the most trusted finishes for reliability in legacy and high-stakes electronics.
Process Capabilities
Our 24 reel-to-reel plating lines are fully capable of applying tin-lead in a range of formats and configurations:
Spot Plating
Apply tin-lead only to terminal points, connector pads, or bond areas for efficient use and targeted solder performance.
Selective Stripe (Single/Dual Sided)
Alloy plating applied only to signal or contact zones where solderability and fatigue resistance matter most.
Control Depth Plating
Maintain precise tin-lead thickness across every reel to match IPC/DoD requirements for finish thickness, alloy content, and solderability.
Overall Plating
Tin-lead coverage across entire surfaces for parts needing complete protection, uniform solder surfaces, or edge-to-edge continuity.
Every plated lot is monitored via SPC, XRF alloy verification, and validated against industry-specific solderability and thickness standards.
Tin-Lead plating is compatible with the following part types and material formats:
Used in aerospace and defense modules where solder performance is non-negotiable and RoHS exemptions apply.
Ensures bond reliability in high-thermal-load environments, particularly when combined with low-temp soldering processes.
Delivers clean alloy surfaces with uniform coverage and proper alloy distribution.
Allows high-speed, reel-to-reel plating for selective or full-coverage tin-lead components in regulated or exempt assemblies.
We can plate your material or manage the full production flow—from strip sourcing to finish and testing.
Tin-lead plating remains the gold standard for solder joint reliability in sectors where failure is not an option.
