KLD-STi7105
For set-top box (STB) SoC chips such as STi7105, STi7111, STi7141, BCM7325, and BCM7425, Shenzhen Kailidi provides professional customized test fixture solutions, which are key tools for professional solution testing and chip verification. Details are provided below. ### I. Introduction: Core Application Scenarios of Test Fixtures **Shenzhen Kailidi Technology Co., Ltd.**, founded in 2013, is a technology-based enterprise specializing in the R&D and production of integrated circuit interface testing products, providing full-process services from chip design verification to mass production testing. **STTi7105 and STi7111** are high-definition set-top box single-chip decoders built by STMicroelectronics (ST) based on a 55nm low-power process. They support **3D graphics acceleration and OpenGL-ES 1.1** and are widely used in high-definition digital television, IPTV, and network interactive set-top boxes. The **BCM7325** is a low-cost, multi-format HD satellite receiver SoC from Broadcom, used by operators such as Sky Deutschland in their next-generation satellite set-top box solutions. The **BCM7425** belongs to the same series of Broadcom HD cable/satellite/IPTV set-top box SoCs, supporting AVC/MPEG-2/VC-1 and other video decoding formats.

Product Details
Based on KLD's accumulated experience in customized test fixtures, its test fixtures for set-top box SoCs (typically BGA-packaged) possess the following core features:
1. **High-Density BGA Pin Adaptation**: These chips utilize high-density BGA packaging. Kailidi's test fixtures are equipped with **high-precision dual-headed spring probes**, enabling precise docking with chip solder balls and ensuring stable and reliable signal transmission. They support a pin count range of 8-2000 pins, flexibly adapting to different chip specifications.
2. **Customized Structure and Ease of Use**: The fixtures typically employ a **flip-type or knob-pressing structure**, facilitating easy operation and ensuring uniform force and accurate positioning of the chip during testing. Precise positioning can be achieved according to the chip's shape and pin dimensions.
3. **Floating Plate Design, Versatile with and Without Balls:** For refurbished chips with potentially damaged or re-balled pins, the **floating plate structure** design allows for reliable testing with and without balls, significantly lowering the testing threshold and making it ideal for the repair and refurbishment market.
4. **Replaceable Probes, Low Maintenance Costs:** Test probes can be replaced individually. When a probe reaches the end of its lifespan or is accidentally damaged, the entire fixture does not need to be scrapped, greatly reducing subsequent maintenance and operating costs.
5. **Wide Range of Applications:** KLD's test sockets are not only suitable for functional testing but also for **burn-in testing**, helping to verify chip reliability under extreme conditions. Its product line is widely used in semiconductors, network digital energy, and other fields.
