Process validation and standards compliance
identifying every operation that was successfully completed, as well as test operations that may have been failed and the number of times a repair attempt was made
• detailed traceability reports identi- fying all material used in a product along with key information about the material such as the manufac- turer, lot and date code informa- tion, and details such as hazardous chemical content
• key process parameters collected from the equipment that was used in assembling and testing the product
• quality reports based on yield and defect information
Te reporting engine needs to be able to summarize the data in different ways such as based on specific units or work orders, from different time frames, and for differ- ent parts of a production operation all the way down to a specific piece of equipment. Te most advanced MES systems pro-
vide comprehensive analysis capability that goes beyond basic reporting to ‘validate’ that the proper processes have been fol- lowed. Tis allows advanced users to do detailed analysis of the data being collected in the manufacturing operation by on the fly modification of the underlying infor- mation being displayed in the reports along with the ability to drill down to ever greater levels of detail. Tis capability allows an operation to identify processes that are open for further optimization allowing a site to implement an effective methodology for continuous improvement.
Conclusion Given the complexity of the number of processes that are involved in manufac- turing printed circuit assemblies and elec- tromechanical systems it is becoming a greater and greater challenge for sites to maintain their certification to industry standards and to achieve high marks in customer based process audits. Investing in the implementation of an advanced MES solution that is tailored for the specific needs of electronics manufacturers can form the basis for a sustainable infrastruc- ture that enables full process validation and control across the entire manufactur- ing site. Coupled with advanced reporting and analysis capabilities, such a solution can aid a site in maintaining their exist- ing certifications, allow them to extend their capabilities to the needs of additional market segments, and continue to main- tain and add to their list of customers.
