Key Points for PCBA Test Fixture Fabrication

After selecting the appropriate control method based on the test requirements and test board, you can proceed with the structural design of the fixture.
1. After selecting the appropriate control method based on the test requirements and test board, you can proceed with the structural design of the fixture. You can design components such as the carrier plate, pressure plate, and connector module. The carrier plate and pressure plate of the fixture should have appropriately sized clearances, and when testing the product, corresponding protective measures should be in place to prevent damage to the test board.
2. The fixture must be accurately positioned, and the connector docking should be smooth and unobstructed.
3. The fixture box features a reasonable internal layout, with ample space for wiring and installation of the control system.
4. The slots for simulating fiber optic/MIC/SPK/SIM cards should be reserved and accurately positioned.
5. The interface positions reserved for fixtures should be correct, sufficient, and reasonably arranged.
6. The locking mechanism for the fixture housing should employ methods such as luggage clasps or press studs to facilitate component replacement and maintenance.
7. Correct zero-point calibration. The zero-point drift of the test fixture can vary depending on changes in test conditions or differences among test fixtures; therefore, zero-point calibration for both open-circuit and short-circuit conditions is essential. Consequently, FCT test fixtures are equipped with settings for both open-circuit and short-circuit calibration.
8. When the fixture experiences broken needles or aging, the needles can be replaced for maintenance and continued use. However, if the fixture is damaged beyond repair or if the customer changes their requirements and no longer needs it, a new fixture must be remade.
Comparative Analysis of Probe Jigs and BGA Test Jigs
A Comparative Analysis of Probe Jigs and BGA Test Jigs In the field of electronic manufacturing, the selection of jigs is crucial for both production efficiency and test quality. Among these, “probe jigs” and “BGA test jigs” are two indispensable tools in modern electronic testing. While each has its own unique features and advantages, they also share certain similarities in some aspects. Today, we’ll take a closer look at a comparative analysis of these two types of jigs to help you better understand their respective characteristics. What is a probe jig? As the name suggests, a probe jig is a device used for circuit board testing. It establishes electrical connections and performs tests by directly contacting solder joints on the circuit board via probes. Such jigs are commonly employed in component functional testing, fault diagnosis, and quality control on production lines. The Advantages of Probe Jigs The primary advantage of probe jigs lies in their flexibility and adaptability. For different types of circuit boards, probe jigs can be adapted to various testing requirements by simply replacing probes or adjusting the layout. Moreover, probe jigs have relatively low costs, especially when used in small-batch production, making them an effective way to reduce testing expenses. What is a BGA Test Jig? A BGA (Ball Grid Array) test jig, on the other hand, is specifically designed for BG

Detailed Explanation of Probe Fixture Types and Their Application Fields
A Detailed Look at the Types of Probe Jigs and Their Application Areas In modern electronic manufacturing, the use of probe jigs is becoming increasingly widespread. They are not only an essential component of testing equipment but also play a critical role throughout the entire production process. If you’re interested in learning about the different types of probe jigs and their application areas, join me as we dive deeper into this topic! What Exactly Is a Probe Jig? Simply put, a probe jig is a device used to test circuit boards or semiconductor chips. It makes contact with the device under test via a series of probes, enabling signal transmission and testing. Think of it this way: just as a doctor uses a stethoscope to listen to a patient’s heartbeat, a probe jig helps us “listen” to the state of electronic devices. Types of Probe Jigs Probe jigs can be categorized into various types based on different classification criteria. Here are some common types of probe jigs: 1. Fixed-Position Probe Jigs This type of probe jig is typically used on production lines. Its design allows the device under test to be securely fixed in one position, ensuring accurate and repeatable testing results. It’s like a tool specifically designed for a particular task—guaranteeing optimal performance every time it’s used. 2. Adjustable Probe Jigs Unlike fixed-position probe jigs, adjustable probe jigs feature a more flexible design, enabling them to adapt to different...
