Eight evaluation links of PCBA processing
        The preparation process of the production plan is actually a process of balancing orders and capacity. When reviewing the PCBA processing and production plan, the production director must pay attention to the requirements and basis of plan preparation, and must consider constraints, evaluate resource allocation, and measure production capacity. This article mainly introduces the allocation of assessment resources. The following is the general process of production planning, each process point has its own assessment focus. The six constraints introduced by the editor in "Six Major Constraints Before the Preparation of PCBA Processing and Production Plans" are the key points of evaluation for each process point.
  Equipment capacity→labor efficiency→order contract→process design→material preparation→energy supply→production schedule→actual order

   1. Equipment capability assessment

  The focus is on the number of equipment, the type of equipment, and the condition of the equipment. In PCBA processing and production, the classification of production machines is as follows: According to the degree of automation, there are automatic machines and manual machines. These models are suitable for the production of different varieties, and the equipment evaluation is to measure and calculate the respective production capacity according to the different models, and to understand the operation of the equipment.

  2, labor efficiency evaluation

  The focus is on the per-unit production quota, shift status, number of start-ups, actual per-unit production, average attendance rate, and average defective rate. Equipment production capacity is not the same as actual production capacity. According to the content listed above, the actual production capacity of different models should be calculated by category.

  3, order contract evaluation

  The focus is on the type, quantity, and delivery time of the order contract. Check whether the requirements specified in the contract match the actual production capacity and whether the production can be completed within the specified time.

   4. Process design evaluation

  The focus is on process requirements, product types and quantities. Check whether the varieties required for the drafting of the contract adopt special processes, whether there are special components, and what is the material consumption of the product.

   5. Evaluation of raw material preparation

  The focus is on the quantity, variety and use time of materials. Confirm whether the prepared materials can meet the needs of drawing up the contract, whether the special components can be prepared before production, and whether the components that need to be reprocessed can be completed on schedule.

   6. Energy supply assessment

   The focus is on the supply of electricity, water, and gas. Determine whether the energy supply can guarantee normal production and whether there is any special energy demand.

  7, production progress evaluation

  The focus is on the implementation of the previous production plan. Understand the actual status of the production schedule and determine the number of days ahead or behind schedule.

   8. Actual order evaluation

  The focus is on the implementation of the number of orders and the preparation of production plans. On the basis of completing the previous assessments, determine the number of contracts that can be accepted, and formulate a new production plan based on the variety, quantity, and delivery time requirements of the accepted contracts.
   In the eight-step evaluation, the key evaluation objects should be equipment production capacity and employee work efficiency, because these two points are the fundamental factors that determine the size of the production capacity. The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
