Software keeps track of quality trends
The need for statistical quality control (SQC) in the manufacture of electronics assemblies is well accepted.
The need for statistical quality control (SQC) in the manufacture of electronics assemblies is well accepted Not only does SQC allow firms to comply with vendor-certification programmes, it is essential for maximising yields, minimising rework and increasing profits

Once the system is established, variable and defect tracking monitors the daily production.
If control charting reveals serious problems, an engineering study can reveal the sources of the problems.
Manually produced control charts can track manufacturing processes acceptably, but collecting and charting the data disrupts the production process while putting extra burdens on assembly and inspection staff.
Also, manual collection and charting do not directly integrate into vendor and in-house reporting systems; data retrieval over any length of time is at best awkward.
Spreadsheet-based charting improves on manual methods, but requires considerable up-front configuration and macro building.
Maintaining macros requires an ongoing inp
