Complete Manufacturing Solutions
From precision PCB assembly to full box build and rigorous testing, we deliver end-to-end EMS solutions with precision, speed, and scalability to meet your production goals.
Box Build Assembly
End-to-end product integration — from sub-assemblies and PCBs to complete, tested, packaged systems ready for global distribution.
LEARN MOREPCB Assembly
High-mix, low-to-high volume SMT, THT, press-fit with advanced inspection (AOI, X-Ray) and IPC Class 3 compliance.
LEARN MOREMetal Fabrications
Precision sheet metal cutting, bending, welding, powder coating and precision sheet metal for durable enclosures and frames.
LEARN MOREPlastic Moulding
High-precision injection, double-shot, insert and over-moulding for complex plastic parts with cosmetic and functional requirements.
LEARN MORECable & Wire Harness Assembly
Complex harnesses, overmolded cables, ultrasonic welding and labeling for automotive, industrial and medical applications.
LEARN MORETesting & Quality Control
ICT, FCT, boundary scan, environmental stress screening, reliability testing and full traceability systems for zero-defect delivery.
LEARN MOREOur Production Process
A structured, transparent five-step process from enquiry to delivery — designed to reduce risk and maximize quality at every stage.
Enquiry & DFM Review
Submit your BOM and Gerbers. Our engineers perform Design for Manufacturability analysis and provide a detailed quote.
NPI & Prototyping
First article inspection and prototype builds validate your design before committing to full production volumes.
Production & Assembly
Full-scale SMT, through-hole, box build and harness assembly on automated lines with real-time quality monitoring.
Testing & Inspection
AOI, X-Ray, ICT, and functional testing with complete traceability records to guarantee every unit passes specification.
Delivery & Aftercare
Secure packaging, on-time worldwide shipping, and post-delivery support to ensure a smooth product launch.
Quality Built Into Every Step
Our quality management system is embedded in every process — from incoming material inspection to final shipment — ensuring consistent, traceable, and defect-free output.
-
Automated Optical Inspection (AOI) 100% board inspection on every production run to catch solder defects, missing or misaligned components.
-
X-Ray Inspection BGA and hidden-joint verification to detect voids, cold joints and bridging not visible to the naked eye.
-
In-Circuit & Functional Testing Electrical and functional verification confirms every board performs to specification before shipment.
-
Full Traceability Component lot traceability and production records are retained for every assembly, giving you complete visibility.
Trusted by Global Leaders
Our customers choose us for quality, reliability and service. Here's what they say about working with Sunstrong.
"Sunstrong delivered our 50,000-unit PCB assembly run on time with zero defects. Their DFM support during NPI saved us two weeks of rework. Exceptional partner."
"We moved our entire box-build program to Sunstrong three years ago. Lead times dropped 30%, scrap rate is under 0.1%. Highly recommend for complex electromechanical assemblies."
"Their IPC Class 3 capability and traceability system gave our aerospace program the confidence it needed. Certified, responsive, and extremely professional."
"The cable & wire harness work was complex — over 400 variants. Sunstrong managed the BOM, handled revision control, and shipped on schedule every quarter. Outstanding."
"From prototype to mass production in 8 weeks. Their NPI team flagged three design issues before first article, which saved us significantly. True manufacturing partner."
"Metal fabrication quality is consistent run after run. Tolerances are held tightly and finish quality meets our branding standards. We've been with Sunstrong for 7 years."
