TF Card Socket External Solder Self-Ejecting/Push-Push Micro SD Card Slot SMD Type (External Solder Pins Easy to Inspect / Self-Eject Locking / Dash Cam/Digital Expansion Card Slot)
External solder pads easy for visual inspection | Push-Push self-eject structure | 8Pin/9Pin SMT mounting | High-quality metal housing for anti-interference | Free samples and CAD drawings available
This TF (Micro SD) card connector features an Outer SMT Pin design with a Push-Push mechanism. The exposed solder pins facilitate visual inspection and manual rework after SMT mounting, significantly improving production line yield. The internal push-push mechanism offers moderate spring force and smooth locking action, effectively preventing card dislodgement caused by vibration. Constructed with high-conductivity copper gold-plated contacts and high-temperature-resistant LCP material, it is widely used in dash cameras, security cameras, smart speakers, digital photo frames, and industrial data acquisition equipment. 2D/3D drawings and free sample requests are available.

【Product Overview】TF Card Socket, External Solder Self-Ejecting/Push-Push (External Solder Feet Micro SD SMT) Memory Card Slot
TF Card Connector, External Solder Push-Push Type (Push-Push Outer SMT Micro SD Card Slot) is a solution specifically designed for consumer electronics, automotive imaging, and industrial data acquisition devices. High-reliability push-push Micro SD memory card connector。
The core highlight of this product lies in its adoption of Outer SMT Leads Design and Push-Push Structure：
- Advantages of the external weld toe structureThe solder fillet extends outward and protrudes. After SMT placement and reflow soldering, visual inspection (AOI) or quality sampling can very intuitively observe the fullness of the solder joint, greatly reducing the rate of cold solder joints and false solder joints, while also greatly facilitating later manual touch-up soldering and rework.
- Self-press pop-up locking mechanismBuilt-in long-life push spring and slide rail lock, a light press completes card locking or ejection, with smooth insertion and removal, preventing card loosening or falling out in bumpy driving or mechanical vibration environments.
The card holder shell uses a high-strength stainless steel shield, offering excellent electromagnetic interference (EMI) resistance and deformation prevention; the internal conductive spring contacts use high-conductivity copper with gold plating, ensuring stable signal transmission without packet loss during high-speed data transfer (such as 1080P/4K HD video recording).
---[Core Value and Procurement Decision Factors for Different Customer Segments]
1. For SMT process and production line PE engineers: External solder feet are easy to inspect, improving soldering yield by 30%
Exposed solder feet make post-reflow solder joints clearly visible, enabling quality control without complex X-Ray inspection, effectively solving the process pain points of internal solder feet being prone to cold joints and difficult to rework.
2. For automotive and hardware R&D engineers: Stable high-speed signal transmission, excellent press-to-pop feel
High-conductivity copper gold-plated contact springs reduce contact resistance, paired with a high-durability spring mechanism, ensuring storage read/write stability under frequent insertion/removal and vibration conditions.
3. For B2B procurement and supply chain managers: Mature universal package, the top choice for cost reduction, efficiency, and supply assurance
Standard PCB layout pad design, compatible with mainstream external-solder pop-up TF card holders on the market, factory-scale production with ample stock, offering extremely high cost performance.
