What points should be paid attention to in the quality management of pcb circuit boards? Jiehao Flexible Circuit Board Factory will organize the following information for you:
The quality control of printing plates is mainly aimed at the design, processing and inspection of printing plates, Мониторинг и измерение.
1. Quality control at the design stage

The quality management work in the design phase includes the following points.
(1) The person in charge of the project reviews the printed circuit board design documents and performs relevant review procedures to ensure that the design documents are valid. печатные платы, изготовленные по настоящему документу, могут удовлетворить функциональные и эксплуатационные требования оборудования, otherwise the design is better and it is a waste paper pile.
(2) The person in charge of the project and the technicians should check the process requirements for the production of printed circuit boards to ensure the manufacturability of the printed circuit boards. технические требования могут быть размещены непосредственно на проектном чертеже, and the content can be written separately. независимо от того, простые или сложные технологические требования, they must show correct, чистый технологический требование. The reviewed technical requirements must meet the current production technology level, экономить, and cost-effective, Содействие последующей сборке, adjustment, тестирование и другие элементы.
(3) Standardizers review the design of printed circuit board test points, конструктивная форма, размер, printed circuit layouts, прокладка, vias, text, etc., Обеспечение проверки и стандартизации печатных плат, and try to meet national standards, требования к государственным военным и промышленным стандартам.
2. Quality management of production and processing links
The quality management work in the production and processing links includes the following points.
(1) The quality department cooperates with the purchasing department to conduct on-site investigations and certify the qualification and production capacity of the printed circuit board manufacturer to ensure the manufacturer's ability to complete the production task.
(2) The designer re-examines the manufacturer's production drawings;. The design of printed circuit boards is often unsuccessful and requires multiple revisions. изготовитель имеет несколько версий обработанных чертежей, and it is necessary to reconfirm the final processing drawings and confirm that the processed printed circuit boards meet the requirements of the final version.
(3) Pay attention to important processes in the production of printed circuit boards. Quality has a great influence on the performance and reliability of printed circuit boards, Необходимо усилить управление качеством. контроль и проверка важных технологических инструкций, установленных изготовителем, such as etching, металлизация отверстий и другие процессы, to ensure that the printed circuits and pads are free of burrs, надрез, and bridge defects, В этих каналах нет опухоли и пустоты. The "stacking" of multi-layer printed circuit boards should also focus on quality control to ensure the thickness, прочность сцепления и точность позиционирования печатных плат. High-frequency boards and microstrip boards usually need to be gold-plated, для обеспечения толщины и чистоты покрытия необходимо разработать специальное техническое руководство по золочению..
3. Quality control at the testing stage
The quality control work in the testing phase is strictly in accordance with the testing basis, using visual or professional tooling and instruments to monitor and measure printed circuit boards, и вести журнал. при наличии специального требования, Необходимо разработать правила профессиональной инспекции.
