Leading Leaded Soldering Services
Leveraging advanced vacuum reflow and selective soldering, we deliver IPC Class 3 compliant assemblies with superior joint integrity and complete mitigation of tin whisker risks.
Are These High-Stakes Challenges Your Reality?
Standard electronics manufacturing is built on compromise. Yours is not. When you are engineering systems for aerospace, defense, or critical medical applications, you operate under immense pressure where the margin for error is zero. We don’t just understand these challenges—we built our entire leaded soldering service to solve them.
The Ever-Present Threat of Tin Whiskers
Are you constantly fighting the risk of microscopic tin whiskers causing catastrophic short circuits in your long-deployment systems? This silent threat in lead-free assemblies is a risk your application cannot afford.
The Damaging Heat of Lead-Free Soldering
Do your high-value, temperature-sensitive, or irreplaceable legacy components face degradation or outright failure from the high thermal stress (220°C+) of standard lead-free processes?
The Quest for Proven, Long-Term Reliability
Do you require solder joints with decades of proven resilience against extreme vibration, g-forces, and relentless thermal cycling? Your system’s success depends on reliability that is measured in years, not months.
The Scarcity of True Leaded Expertise
Are you tired of partners who are merely willing to run a leaded process? Are you searching for a true specialist who is strategically invested in delivering IPC-A-610 Class 3 results with a state-of-the-art, dedicated production line?
Our leading leaded soldering technology configuration
To solve your unique challenges, we didn’t just build a leaded line; we engineered a fortress of reliability. Every piece of equipment in our dedicated facility was strategically chosen to eliminate common points of failure and to deliver flawless, verifiable, military-grade results.
Near-Zero Voids for Maximum Reliability
The Challenge: Standard reflow traps gas in joints—especially under BGAs—creating voids that reduce thermal conductivity and weaken long-term reliability.
Our Solution: After solder reflow, we apply vacuum extraction followed by nitrogen backfill, preventing oxidation and eliminating trapped gases.
Your Benefit: Voiding rates often below 1%, delivering superior thermal performance and durability under mechanical stress.
Precision Soldering for Complex Boards
The Challenge: Traditional wave soldering risks overheating nearby SMT parts on mixed-technology assemblies.
Our Solution: Our selective system uses a programmable mini-wave to apply solder only where needed — with pinpoint accuracy.
Your Benefit: Clean, repeatable joints with zero thermal risk to adjacent components, even on the most complex layouts.
Military-Grade Board Cleanliness
The Challenge: Flux residue on high-impedance or RF circuits can absorb moisture, causing corrosion and signal issues.
Our Solution: A multi-stage aqueous cleaning process using advanced chemistry ensures complete contaminant removal.
Your Benefit: Boards meet or exceed IPC-J-STD-001 and military standards, ensuring long-term electrical performance.
Premium Materials & Process
The Challenge: Equipment alone can’t guarantee quality — materials and controls matter.
Our Solution: We use only top-tier Sn63/Pb37 solder from Kester and Indium, under strict IPC-A-610 Class 3 process control.
Your Benefit: Full material traceability, high process consistency, and confidence in every board we ship.

Frequently Asked Questions
We have no strict MOQ. Whether it’s a small-batch prototype or a high-mix low-volume run, we can flexibly support your needs.
Yes. We specialize in matching legacy assembly specs — including soldering temperature curves, flux usage, and cleaning protocols — to ensure compatibility with older systems.
Simply send us your Gerber files, BOM, and assembly notes via email or our quote form. Our engineering team will review the data and respond with a quotation and DFM recommendations.
Absolutely. We offer early-stage DFM (Design for Manufacturability) consultation to help you optimize pad layout, via design, and thermal relief for leaded processes.
Yes. We welcome on-site visits (by appointment) and can provide virtual factory tours or process documentation if needed for vendor qualification.
We can accommodate a range of requirements — from anti-static packaging to MIL-STD compliant labeling and barcoding. Just let us know your project specifications.
Yes, we offer optional services such as conformal coating, potting, or masking upon request, depending on your environmental protection needs.
