How to ensure the quality of 24-hour FPC expedited sampling products

For expedited samples, the first step is to ensure their production speed. We will discuss it based on 24-hour expedited FPC sampling. Short production time means ensuring the success of a batch, as time does not allow for secondary production, and there are high requirements for production equipment, technology, material selection, and production personnel.



1. Quickly optimize the design graphics. When obtaining a design drawing, the first thing to ensure is whether its producibility is reasonable. Secondly, it is necessary to optimize the design drawings to ensure that the product removes excess wiring and reduces wiring area without affecting performance.



2. Choosing the appropriate substrate is one of the most important factors in the production of expedited circuit boards. The selection of materials for circuit boards is diverse, and only by selecting the right materials for the production of expedited circuit boards can unexpected elements not occur during production.



3. The production process program is flexible, and there are always unexpected situations when producing circuit boards, especially flexible circuit boards. This requires our engineers to propose reasonable solutions to various problems that arise in production, avoiding rework and rework.



4. Inspection: After sampling the finished circuit board, first check the appearance and welding of the product to see if there are any issues that do not match expectations, such as missing parts, incorrect parts, component reversal, and cold welding of empty solder joints. Poor inspection does not mean that the product is unqualified, but rather ensures that there will be no fundamental issues. As for why the product is unqualified, electrical testing should be conducted on the product.



5. Product data analysis can serve as a basis for designing product parameter corrections. The electrical properties of the finished circuit board are fundamental, and it is definitely not possible for the circuit board circuit to be disconnected. Generally, these methods are used for the electrical properties of circuit boards: specialized type, which is generally used during mass production. There are also more high-end flying needle and composite fixtures that can be used for electrical properties and product conductivity.



6. The requirements of production personnel, the time for expedited sampling is the cost. Ensuring rapid production requires experienced production personnel, as there are many procedures for circuit boards that require manual operation. Having employees with strong production capabilities is a practical capital for a circuit board factory to quickly sample.
