1. The materials, process flow, parameters, inspection methods, and quality requirements for FPC flexible circuit board products are all communicated to the production department and outsourcing units via the preparation of manufacturing instructions (MI).
2. The delivery cycle for FPC flexible circuit boards necessitates production management to oversee the entire process from order placement to production completion. This requires the ERP system to facilitate production scheduling and work-in-progress management, ensuring timely delivery and responsiveness to customer needs.
3. Typically, FPC boards are categorized by the number of layers, including single-sided, double-sided, and four-layer boards. The materials, process flow, parameters, inspection methods, and quality requirements for these flexible circuit board products are communicated to the production department and outsourcing units through the preparation of manufacturing instructions (MI).
1. For products with four-layer boards and below, the process flow is relatively straightforward. The production process card can be completed from start to finish without the need to alter the process or replace the process card mid-way.
2. In contrast, for blind and buried vias products with more than six layers, different inner and outer layers feature distinct circuit diagrams, process flows, and parameters, requiring the use of various molds, films, and auxiliary equipment. This necessitates different production instructions and related documents, which will lead to the generation of specific production process cards to manage the manufacturing process and quantity of various inner and outer layers.
3. During production, multilayer boards will have unique inner codes that must be differentiated by various codes throughout the process, employing different production process cards to monitor production progress. The FPC flexible circuit board relies on the transfer and handover of auxiliary products through batch cards (Lot Cards), commonly referred to as the number of passes.
4. Given the extensive range of online products and their complex models, operations involving counting, scrapping, and repairs require simple, fast, and fault-tolerant procedures. Throughout this process, I have found that standard ERP systems are largely inadequate for handling the nuances of separate encoding, over-numbering, scrapping, and replenishing of inner and outer layers.
5. Generally, the more detailed the production operation plan, the richer and more valuable the information it provides, making it increasingly difficult to calculate accurately. Conversely, a rougher production plan yields less information and lower value. The process flow associated with FPC is often more intricate.
6. The engineering data and MI production for a complex FPC multilayer board can take a considerable amount of time to complete, while customer delivery deadlines are often very tight.
7. Lastly, the FPC flexible circuit board industry functions as a foundry, where design changes for FPC products occur frequently, and versions are often updated. When a customer alters a version, both the manufacturing instructions and process flow cards must be revised, which may involve changes in some areas while remaining unchanged in others.
