While designing any product, there are various aspects of the layout and design that need to be considered in order to achieve success in both product functionality and product manufacturing. QSIC Vietnam, Ltd. is committed to our customers’ success and being partners for life. We offer the following services and end item deliverables supporting your needs for faster time to market, cost effectiveness and manufacturing excellence.

Design Considerations

Design for manufacturing and design for testability are value-add services offering the greatest benefit when used early on in the concept stage of the design and product development process. DFM/DFT is a complete concept involving:

  • Identification of design guideline violations, costly or unnecessary parts, trace errors and assemblies, prior to manufacturing
  • Integration of both manufacturing processes information and estimates of manufacturing costs allow for intelligent materials decisions
  • Potential difficulties in the downstream manufacturing are eliminated in the design and prototyping stages
  • Streamlining cost reduction initiatives

Immediate advantages include:

  • Decreased scrap rates
  • Reduced manufacturing costs
  • Eliminate or reduce rework
  • Increased product quality and reliability
  • Quicker turn-around times and faster time to market
  • Mass production
  • Help support to market customer’s products in Vietnam per customer’s requests

PCB Lay-Out

  • Design for cost effectiveness, testability and manufacturability.        
  • Seamlessly transfer customer design from concept to schematics to layout design & to PCB fabrication, early BOM exposure, turnkey material and PCBA assembly
