Project Background 
A certain intelligent device company plans to develop a high-end industrial control product, with the core requirement being a high-performance circuit board that supports multifunctional integration and high-speed signal processing. This design must meet the following technical requirements: 
Multi layer PCB wiring: requires handling complex signal layering and interference isolation. 
Micro spacing component welding: The minimum component size reaches 0201 specification, and the welding accuracy requirement is extremely high. 
High frequency signal integrity: A customized impedance control scheme is required to ensure signal transmission stability. 
Quick delivery: 50 sample pieces need to be produced and tested within 3 weeks, and support subsequent mass production.

Niu Wei Industrial's OEM solution 
Design optimization stage 
Manufacturability Review (DFM): The engineering team of Nuwi Industries communicates deeply with customers to optimize component layout to reduce wiring cross interference and lower production difficulty. 
Customized process design: Develop impedance control schemes and signal integrity testing processes based on high-frequency signal characteristics to ensure product performance meets standards. 
Production execution stage 
High precision equipment investment: Imported eight arm surface mount machines (such as Siemens and Panasonic brands) are used to achieve a mounting speed of 60 components per second, ensuring the welding accuracy of micro pitch components. 
Lead free soldering process: using environmentally friendly lead-free solder, combined with 3D SPI (solder paste inspection) and AOI (automatic optical inspection) equipment, to achieve full process quality monitoring. 
Flexible production line configuration: Real time scheduling of production resources through ERP system, supporting flexible demand from 50 sets of trial production to 100000 sets of mass production, avoiding customer equipment depreciation pressure. 
Quality Control and Delivery 
Strict testing process: Conduct comprehensive tests on the electrical performance, voltage resistance, temperature stability, and other aspects of the sample to ensure that key parameters meet the design requirements. 
Fast delivery capability: With the support of the Yangtze River Delta supply chain cluster, 80% of components can be urgently replenished within 2 hours, and the final sample delivery can be completed within 3 weeks and verified by customers. 
Project achievements 
Technological breakthrough: Successfully solved the problems of high-frequency signal interference and micro spacing welding, with a product yield rate of 99.8%. 
Cost optimization: By scaling up procurement and simplifying non critical testing processes, we help customers reduce single board costs by 15%. 
Long term cooperation: With this performance, Niuwei Industrial has become a long-term partner for customers and will undertake multiple complex product development projects in the future.
