Development Cycle Concept Research Circuit Design Packaging & Printed Circuit Design Prototyping or Trial Production Design Review Manufacturing Setup including test Setup Documentation Agency Compliance Follow up Sizing up the task
Concept Idea for a new product, A variation on an existing product, The identification of a need for an undefined product
ResearchResearch is to drive realisation of Concept by Identifying Technology Finding Methods People/Company Producing
Circuit Design Creation of Schematic Diagram BOM generation Prototyping the functional blocks Final Integration
Packaging &Printed Circuit Design Selection of Suitable shapeand size, Mechanical drawingto be designed using CAD/CAM Material for Housing basedon application requirement. PCB is finalised accordingly.This is final PCB which is easyto assemble.
Prototyping or Trial Production 3D plotting / Hand made prototyping Post mould production for design and function finalisation
Design ReviewEvaluation of Prototype for Function Appearance Built- cost reduction / optimisation possible enhancements to exceed the original goals even marginally
Manufacturing Setup including test Setup Production line for manufacturing Testing on Line, Calibration and Final Testing of finished product. Long term testing of each lot of produce.
Documentation Concept HLDD ( High Level Design Documentation) Circuit diagrams with functional explanation Schematics and PCB designs Parts List / BOM with pricing Sources of procurementMechanical Drawings of the Enclosure Mould usage documentation Assembly line documentation Assembly process and Time Lines Product Packaging ( Cushions etc.. )Goal is to Document complete Life cycle andProduction process for enabling any EMSprovider to manufacture the product.
Agency Compliance Agency compliance may be required by law. For product liability insurance coverage. Agency compliance can cost several thousand dollars per agency Can add months of time to accomplish. It is not to be taken lightly or left as an afterthought.
Follow upThe manufacturing facility experience, The product support data, The user responses,Review for the purpose of steering future designs and marketing.Dont forget this crucial step on the road to improved quality, value, and often lower cost.
Sizing up the taskThere isGood, Cheap, and Fast.You can only have twoof the three at any one time.If you can buy something, do not build it or anything similarwithout some truly overwhelming justification.Always make a mock up or model, even if it is cardboard withhand drawn features. It will pay for itself again and again, andyou will learn something crucial each time you build one.
