80 SMT Magazine • September 2016 al data in more detail identified in linked cells such as a Test Cell, Hazardous Sub- stance Cell, Counterfeit Component Cell • Unique materials or sub-assemblies are identified individually by unique ID (e.g., battery, screen/display, HDD, random- access memory (RAM) module, CPU, etc.). Additional requirements are needed for these materials, such as manufacturer unique ID. Information is defined in the associated Assembly Cell if it is a sub- assembly and Test Cell for example. • A software component of a product is treated in the same way as a regular material, that is, as part of the BOM, with related traceability, for example software revision checksum (CHKSUM), documen- tation of software processes, etc. • Other cells exist for packing and shipping materials, and labels Process Data Cells: • This cell describes the process history to create the assembly • Information about the work order is de- fined in the associated Work-Order Infor- mation Cell • A list of actual processes, in sequence. The actual number of process sequences may exceed the number specified in the work- order (i.e., due to repair loops). Process data are required for each listed process, according to the chosen level of traceabil- ity. • Due to the varied nature of the many pos- sible production process, and the wide range of associated data, the process data is split into two sections. The first con- tains the common process traceabili- ty data, applicable to all processes equal- ly, and the other is the process dependent section containing the unique process traceability data elements • Common Process Traceability data in- cludes logical process name as described in the work-order, serious process excep- tion, such as breakdown event, unique process ID, date and time in / out of the process, operational documentation, pro- gram / setup data (name / revision / date), process operator, date of last PM / calibra- tion, completion certification and envi- ronment data. • Unique Process Traceability Data is de- fined for each type of process, including: – Unique PCB Marking: the marking of the PCB and or individual boards with a unique ID that can be scanned to identify the specific board. – Product Routing Station: including PCB flip / turn, storage / stock / waiting area, etc. – Screen Printer: including stencil ID (unique ID or part number), duration that the paste had been opened, number of cycles performed by the stencil since maintenance, age of squeegee/syringe, total cycle count, etc. – Automated Paste Inspection: including pass/fail result, inspection/ test record detail or even retained images – Glue Dispenser: including stencil and squeegee ID if applicable, number of cycles since last maintenance, programmed speed/pressure, Duration since glue removed from cold storage, etc. – SMT Placement: including material exchange events, verification events, pass / fail of visual inspection, manually recovered pick-up error cycles, automated material exchange event, automated splicing detection, fiducial read-error event, panel location error, MSD-remaining exposure time for each MSD component, automatically recovered pick-up error cycles, instances of safety stop and other machine stops or exceptions, actual nozzle used per each reference designator, etc. – Pin Through-Hole Insertion: Including material verification, manual material exchange event, splice (joining the tape), manually recovered pickup error cycles, material exchange event fiducial read error, panel location error, instances of safety stop and other machine stops or exceptions. – Manual PCB Assembly: Including IPC-1782 STANDARD FOR TRACEABILITY SUPPORTING COUNTERFEIT COMPONENT DETECTION
