Description
TECHNICAL FIELD
[0001] The utility model relates to electronic manufacturing technical field, concretely is manual test anti -hole PIN fixture. BACKGROUND
[0002] With the rapid development of modern electronic technology, the manufacturing process of electronic products is increasingly complex, and the quality of the circuit board as the core component of the electronic product directly affects the performance and reliability of the product. In the production process of the circuit board, welding is a crucial link. The traditional welding method mainly relies on manual operation, and the worker observes whether the pins of the components on the circuit board have poor welding (such as anti-hole PIN) by naked eye. However, with the development of electronic products towards miniaturization and high density, the components on the circuit board are more and more, and the pin pitch is smaller and smaller, and the traditional manual detection method faces great challenges.
[0003] Firstly, manual detection is prone to visual fatigue, leading to missed detection or misjudgment. Long time staring at the tiny components on the circuit board for observation, the detection personnel is easy to produce fatigue, thereby neglecting some subtle defects. Moreover, the visual resolution of human is limited, and it is difficult to accurately identify very small components or extremely subtle welding defects. This makes some circuit boards with anti-hole PIN (i.e. the pins of the components are not correctly welded, forming a hollow or virtual welding) may flow into the next production process, bringing potential risks to product quality. Secondly, manual detection is low in efficiency and cannot meet the needs of large-scale production. In modern electronic manufacturing industry, production efficiency is one of the key factors of enterprise competitiveness. The traditional way of manually detecting each welding point on the circuit board is extremely slow, especially when facing a large number of circuit boards for detection, which will seriously restrict the overall efficiency of the production line. This not only increases the production cost, but also may lead to the extension of product delivery cycle, which cannot meet the market demand in time.

[0028] With the development of electronic products towards miniaturization and high density, the components on the circuit board are more and more, and the pin pitch is smaller and smaller, so the traditional detection method has been difficult to meet the production demand.

This connection mode ensures that the optical fiber sensing module 302 can continuously and stably receive electric energy during work, thereby ensuring its normal operation and improving the efficiency and accuracy of detection. At the same time, the optical fiber amplifier 303 is arranged in the inside of the optical fiber sensing module 302, which can timely and effectively amplify the optical signal received by the optical fiber sensor probe 400, further enhancing the strength and clarity of the detection signal, which is conducive to subsequent signal analysis and judgment.
