For the BGA315 package, widely used in Apple device memory chips, Hiseecon provides professional and highly customized test fixture solutions. Details are provided below.
 I. Introduction:
Core Application Scenarios of BGA315 Test Fixtures
For BGA315 packaged NAND Flash memory chips (commonly found in iPhone 14 series, iPad, and Mac devices), Hiseecon customized test fixtures are core tools in the fields of mobile phone repair, data recovery, and chip functional verification. In the mobile phone repair and memory chip refurbishment market, this fixture is typically used in conjunction with a professional programmer to perform operations such as reading, writing, and formatting data on the chip, making it a powerful tool for recovering important device data or performing chip-level repairs.

II. Product Details: Five Core Features

Based on Hiseecon's professional customization capabilities in BGA testing, its BGA315 test fixture possesses the following core features:

1. Precise Adaptation to Apple Memory Chips: Specifically designed for BGA315 packaged NAND Flash chips, it is perfectly compatible with memory chips used in devices such as the iPhone 14 series, ensuring accurate pin contact during testing.

2. High-Reliability Probes and Structure: Utilizing imported double-headed spring probes, the mechanical life can reach over 100,000 cycles, ensuring stable performance. The fixture typically adopts a flip-top structure for easy operation, and through integral molding and spring self-adaptive structure, it is compatible with different chips ranging from 0.6-2.0mm in thickness, guaranteeing good contact.

3. Floating Plate Design, Versatile with and Without Balls: Employing a floating plate structure design, this core advantage allows for testing regardless of whether the chip pins have balls or not. Furthermore, users can replace the limiting frame according to different IC sizes, achieving greater versatility and effectively reducing usage costs.

4. Easy to maintain and cost-effective: The 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, simplifying maintenance and significantly reducing subsequent usage and maintenance costs.

5. Wide operating temperature range and brand compatibility: The operating temperature range is from -40℃ to 140℃, adaptable to various testing environments. Furthermore, the test socket is designed for compatibility, supporting ICs from mainstream brands such as Toshiba, Samsung, Hynix, Intel, and SanDisk.
