The NCP139 is a 1 A VLDO equipped with an NMOS pass transistor and a separate bias supply voltage (VBIAS). The device provides a very stable, accurate output voltage with low noise, making it suitable for space-constrained, noise-sensitive applications. To optimize performance for battery-operated portable applications, the NCP139 features low IQ consumption. The WLCSP6 1.2 mm x 0.8 mm Chip Scale package is optimized for use in space-constrained applications. The testing of this chip requires a test socket that meets the specific requirements of the chip, including basic parameters such as overcurrent capability, probe pressure (WLCSP-type chips are relatively fragile and require low-pressure probes), low contact impedance for more precise testing, chip heat dissipation, ESD capability, and insulation impedance.
In today’s electronics industry, chip testing is crucial. Our test socket is designed specifically to meet the testing requirements of the WLCSP6 chip. Its features and basic parameters align with the testing needs of the WLCSP6 chip.
Firstly, our test socket has excellent overcurrent capability. This is achieved through the use of high-quality materials and advanced design to effectively handle large currents, ensuring that overcurrent issues do not arise during testing. This is particularly important for testing chips like the NCP139, which features a 1A VLDO and NMOS pass transistor.
Secondly, our test socket uses low-pressure probes. We understand that WLCSP-type chips are relatively fragile, so our test socket employs low-pressure probes to ensure quality contact without damaging the chip.
Additionally, our test socket has very low contact impedance. Low contact impedance allows current to flow smoothly, leading to more accurate test results and better evaluation of the performance of the NCP139 chip.
Our test socket also offers excellent heat dissipation. During testing, chips can generate significant heat, and if not dissipated effectively, this heat can affect chip performance or even damage the chip. Our test socket features efficient heat dissipation design to quickly remove heat and protect the chip.
Furthermore, our test socket has excellent ESD protection. Static electricity can potentially damage chips during testing. Our test socket incorporates advanced ESD protection design to effectively prevent static electricity damage to the chip.
Finally, our test socket has high insulation impedance. High insulation impedance prevents current leakage, ensuring testing accuracy.
In summary, our test socket is the ideal choice for testing WLCSP6 chips. Its outstanding performance and features will help you conduct more accurate and effective testing.
