Ultimate H3.0 SMT Under-board SD Card Socket VTC402012992

Product Overview The VTC402012992 is a precision-engineered SD card connector designed to optimize PCB space through an under-board mounting configuration. It utilizes a manual (No Push) mechanical system, which eliminates spring failure risks in high-vibration environments. Constructed with heat-resistant LCP black plastic and a durable stainless steel shell, it is optimized for high-accuracy automated SMT assembly processes.

FAQs

1. What is the benefit of an under-board mounting design? The under-board design allows the connector to sit beneath the PCB, effectively reducing the height impact on the topside of the board, which is ideal for ultra-slim hardware.
2. Is this socket compatible with high-temperature soldering? Yes, the housing is made of LCP (Liquid Crystal Polymer), a high-temperature thermoplastic designed specifically for reflow soldering processes.
3. Does this model have a spring ejection mechanism? No, the VTC402012992 features a “No Push” (Manual) mechanism for users to manually insert and remove the card, which increases long-term mechanical reliability.
