Chip Test Fixtures & Programming Solutions

Custom IC Test Fixtures for Validation, Programming & Engineering Testing

MangoSolution-Tech provides engineering-driven chip test fixtures and programming solutions focused on IC-level validation, firmware programming, and engineering testing. Our solutions support accurate, repeatable, and efficient testing for semiconductor and electronics teams during IC evaluation, firmware development, and early-stage production preparation.

Why Chip Test Fixtures Matter

As integrated circuits become more complex, manual probing and ad-hoc testing methods are no longer sufficient. Without dedicated chip test fixtures, engineering teams often face inconsistent results, contact instability, risk of pin damage, and low testing efficiency. Well-designed chip-level test fixtures transform testing into a controlled and repeatable engineering process.

Our Test Fixture Capabilities

IC Test Fixtures & Sockets

We design and manufacture custom IC test fixtures to ensure stable electrical contact and accurate signal access. Support includes QFN, QFP, BGA and other IC packages.

Programming Fixtures (IC-Level)

Programming fixtures are a specialized form of IC test fixtures, designed specifically for reliable firmware programming and verification at the chip level. They support MCU and programmable IC programming using ISP or offline methods.

Customized Chip Test Solutions

For non-standard IC packages or special validation requirements, we provide project-based customized chip test solutions with mechanical and electrical co-design.

Test Fixture Case Examples

Case 1: IC Programming & Verification Fixture

Application: IC programming and verification prior to assembly. Highlights include stable socket contact, accurate pin alignment, and suitability for engineering use.

Case 2: Custom Chip Validation Fixture

Application: IC validation and debugging in engineering laboratories. Designed for accurate positioning and repeatable measurements.
