68 PCB007 MAGAZINE I MAY 2018 After going over some slides on understand- ing the activities and application of CIM, in- cluding integration of "Islands of Automation," I landed on the CIM-directed modernization plan as seen in Figure 1. This is the blueprint for automation and consists of six phases: 1. Environment assessment 2. Program strategy 3. Conceptual design 4. Detailed design and requirement specifications 5. Deployment of design 6. Implementation and execution Phase 4 is the most important step, as it de- fines the requirements definition (RD). The RD requires a planning methodology, and I went over the method of benchmarking human and machine activities for mechanization and sys- temization (data and information) for each pro- cess workstation for the entire manufacturing process. The definitions of mechanization and systemization are seen in Figure 2 and capture all the labors of production workers and auto- mated machines and their information. By de- fining each workstation (the present), the in- cremental improvement in mechanization and systemization can be planned (the future), as seen in Figure 3. I went on to further define mechanization in PCB fabrication and the dimensions of system- ization including modern networking and ap- plication software developed to integrate pur- chased software into PCB equipment. The use of the SEMETECH GEMS/SECS II protocols from the IC wafer fabrication industry provid- ed a useful model to follow. Figure 1: The six phases of a CIM-directed modernization plan. CIM Directed Modernization Plan 1 PHASE 1 ENVIRONMENTAL ASSESSMENT (4-8 WKS) • Conduct Systemization Review (flow, quality, etc) • Conduct "the CAD/CAM Audit" • Perform "The Process Scan" • Perform Organization Review • Analyze Business Forecast • Profile of Systemization / Mechanization opportunities • CAD/CAM Systems specification input • Assessment of organizational impact • Rationale for cost / benefits analysis model PHASE 2 PROGRAM STRATEGY (6-10 WKS) • Perform macro-level stimulation for CBA • Establish performance targets • Create CIM strategy & automation plan • Develop documentation methodology for CIM system • Documented CIM strategy & implementation plan • CIM architecture • Organization & staffing plan • Database mapping of functional processes PHASE 3 CONCEPTUAL DESIGN (6-10 WKS) • Exploration of preliminary process equipment & automation alternatives • Initiation of requests for information (RFI) • Develop conceptual specs for MFG support systems • Organize manufacturing technology teams • Budget profiles on equipment / software development created • Documented conceptual specifications for functional approvals PHASE 4 DETAILED DESIGN & REQUIREMENTS SPECS (13-26 WKS) • Generation of detailed process/equipment designs • Generation of detailed manufacturing support sizing of system specs • Involvement with technology suppliers • Creation of integration plans • Execution of simulation model on automation alternatives • Creation of RFP specs for supplies • Transaction (I/O level) design document for manufacturing system • REF Specification with functional sizing of system • Detailed cost/benefits model document • Implementation plan PHASE 5 DEVELOPMENT (Cycle depends on Phase 4 scope) • Selection of equipment, hardware, & software suppliers • Implementation of development hardware & software • Software programming • Debug & test subsystems • Completed system software • Installed, operational equipment PHASE 6 IMPLEMENTATION (Cycle depends on Phase 4 scope) • ConstructATP • Executionofsystemtest • Constructsystem&userdocumentation • ExecuteATP • Trainerofend-users • Acceptance of test procedures • Operational CIM systems • Technical & user documentation DELIVERABLES ACTIVITIES ACTIVITIES DELIVERABLES
