Our services are built to accommodate high-mix technologies, surface mount technology (SMT), and multi-layer boards, catering to a wide array of applications. Whether it’s new product introduction (NPI), reballing & BGA replacement, or full system integration, our advanced processes ensure precision and efficiency from concept to final shipment.
New Product Introduction (NPI)
NPI is one of the foundational elements of our PCB assembly services. Our dedicated team works closely with clients to streamline the launch of new products, reducing time to market while ensuring that all design specifications and industry standards are met. Our NPI services integrate Design for Manufacturing (DFM) and Design for Testability (DFX/DFT) principles, which optimize the product for both production efficiency and testing reliability.
In this phase, we help our clients transition smoothly from prototype to mass production, focusing on risk mitigation and quality assurance. We also offer functional testing and testing & inspection at every stage to ensure high-reliability outcomes.
Still Have Questions?
PCB Assembly
At the core of our services is our PCB assembly process. We specialize in high-mix, low-to-medium volume assembly, offering solutions for complex BGA, 01005 placement, and POP (Package on Package) placements. With cutting-edge SMT capabilities and expertise in handling multi-layer boards, we ensure that our assembly solutions meet the demands of advanced, compact, and high-reliability applications, particularly in medical electronics and industrial electronics sectors.
Our production facilities utilize paperless production systems to improve efficiency, reduce errors, and enable full traceability throughout the assembly process.

Comprehensive Testing Plan
Quality and reliability are crucial in PCB assembly, especially when serving industries such as aerospace, defense, ATEX and medical devices. We implement a comprehensive testing plan for each PCBA (Printed Circuit Board Assembly), ensuring that all assemblies meet the highest standards. Our IPC 610 and IPC Rework & Repair Class 2 standards ensure precision and durability.
Testing methods include:
1. Automated Optical Inspection (AOI)
2. Functional Testing
These methods ensure that your assemblies meet the most stringent quality and reliability expectations.
Purchasing and Supply Chain Management
Efficient purchasing and supply chain management are vital to ensure seamless production. Our purchasing department works closely with trusted suppliers to source high-quality components that are RoHS compliant and meet all industry certifications, including ISO 9001 and UL standards. With access to a global supplier network, we offer competitive pricing and ensure that components are available on time, helping to keep production on schedule.
DFX/DFM Services
Our commitment to quality starts at the design phase. Our Design for Manufacturing (DFM) and Design for Excellence (DFX) services are tailored to optimize your product for cost-effective production and ease of assembly. By identifying potential design flaws or areas for improvement early in the process, we help minimize errors and reduce costs while maintaining the highest levels of reliability.
Full Turnkey Solutions
Our full turnkey service is designed to manage every aspect of your PCB assembly, from design and component sourcing to assembly and testing. This all-inclusive service allows us to take full control of the production process, ensuring smooth operations and consistent quality. Clients benefit from the convenience of having a single point of contact for all their PCB manufacturing needs.
Our full system integration services take this a step further, offering complete system assembly and final product testing. This end-to-end solution is particularly beneficial for companies looking to streamline their supply chain and reduce time-to-market.
Planning and Logistics
Behind every successful project is careful planning and meticulous execution. We work with our clients to develop a planning strategy that meets their timelines and production requirements. Our skilled project managers ensure that every stage of the process, from initial concept to final shipment, is carefully coordinated to avoid delays and meet all deadlines.
Additionally, our shipping services guarantee that your final product is delivered safely and on time. Whether it’s domestic or international logistics, we offer tailored solutions that cater to your needs.
Industry Standards and Certifications
Adhering to the highest standards in the industry is a critical part of our service offering. We comply with multiple certifications and standards:
- RoHS for environmental compliance
- UL for safety certification
- ISO 9001 for overall quality management
- IPC Class 3 & 3A for high-performance electronic assemblies
Our commitment to these standards ensures that our customers receive products of the highest quality, no matter the industry or application.
Our PCB assembly services provide a one-stop solution for clients in need of advanced, high-reliability PCB manufacturing and assembly. Whether it’s through our NPI, DFX/DFM, full turnkey, we maintain a focus on quality, reliability, and customer satisfaction.
From the initial design adoption phase to the final delivery, we work to ensure that your product is not only manufactured to the highest industry standards but also optimized for performance, cost-efficiency, and scalability. With decades of experience and a strong commitment to excellence, we are the ideal partner for your next PCB assembly or box build project
