The FPC soft board industry has a short lead time, which requires production management to control the entire production process from order placement to production completion. This requires the ERP system to provide production scheduling and work in progress management to ensure production lead time and customer response speed. Therefore, the most critical competitive advantage of FPC soft boards lies in the aspects of engineering design, production management, material control, manufacturing, outsourcing processing, etc., especially in the WIP control of on-site production management. If WIP control is improper, there will be many mismanagement phenomena such as missing, stagnant rotation, inaccurate WIP quantity, delayed replenishment, increased wire change frequency, and unclear delivery time.

There are various types of FPC soft board products, which are generally distinguished based on the number of layers, including single panel, double-sided board, multi-layer board, soft hard combination board, etc. The processing materials, process flow, process parameters, testing methods, quality requirements, etc. of FPC soft board products will be issued processing instructions to the production department and outsourcing units through the preparation of manufacturing instructions (MI). ­ For products with double-sided boards and below, the process flow is relatively simple, and the production process card can be completed from beginning to end, without the need to switch processes or replace process cards midway.

In the production process, multi-layer boards will have different inner layer codes, which must be distinguished through different codes and controlled by different production process cards to control their production progress. ­ Generally speaking, the more detailed the production operation plan, the richer and more valuable the information it provides, and the corresponding calculation becomes more difficult. The rougher the production operation plan, the less information and lower the value. The process involved in FPC soft boards is often complex. The engineering data and MI production of a complex FPC multi-layer board often take a long time to complete, and the delivery time required by customers is often very urgent.
