PCBA Manufacturing & Test
With more than 15 years of experience working in partnership with industry-leading Original Equipment Manufacturers (OEM’s), TOPSCOM PCBA LIMITED has been a pioneer in surface mount technology (SMT), fiber optic assembly, and lead-free materials processing. Printed circuit board assembly and testing is at the heart of our manufacturing services, and we offer the latest in materials, board sizes and finishes to improve performance. Our complete range of electrical and mechanical testing for cables, harnesses, PCBAs, subassemblies and systems are designed to meet our customer’s requirements and specifications. We cover the entire life cycle of electronic products – from prototype development and NPI, through to growth and maturity and end-of-life phases.
Engineered Prototyping and New Product Introduction (NPI)
Prototyping is an integral part of the system design process. Our OEM customers take advantage of our on-site, rapid prototyping services to verify functionality and manufacturability. Early visibility of the prototype can identify problems and minimize risk, while increasing output, reducing development costs, and accelerating development cycles. TOPSCOM PCBA LIMITED’s New Product Introduction (NPI) is a vital cross-functional business process which enables new products to be manufactured and addresses their entire lifecycle – from conception to end-of-life. TOPSCOM PCBA LIMITED provides intelligent solutions that give customers a competitive edge.
Functional Testing Capabilities
Comprehensive testing applied throughout new product development saves customers money while reducing manufacturing downtime. At the earliest stages, in-circuit testing, automated optical inspection (AOI) and Agilent 5DX inspection provide vital feedback that facilitates timely adjustments. Then functional and application testing are performed to individual customer specifications before rigorous environmental stress screening verifies product reliability. When it comes to introducing a new product, TOPSCOM PCBA LIMITED suite of functional and testing capabilities ensures that building it right the first time, and delivering a solution that exceeds expectations.
