PLCC Socket 32-pin SMT, phosphor bronze contacts, 1A current rating, model EB770429377

PLCC Socket 32-pin SMT with phosphor bronze contacts is a surface-mount device designed to accept 32-pin PLCC integrated circuits. The socket provides a reliable removable interface between the PCB and the IC, enabling straightforward insertion and removal for prototyping, repair, or field replacement. Rated for a continuous current of 1 A per contact, it is intended for low-current digital and mixed-signal applications where secure electrical contact and minimal contact resistance are required.

Advantages

The phosphor bronze contacts offer good spring characteristics and corrosion resistance, ensuring consistent contact force and low contact resistance over many cycles. SMT package allows automated placement and soldering during PCB assembly. The socket's construction supports repeatable IC insertion and removal without soldering the device directly to the board, which simplifies testing and maintenance workflows.

Suitable for

• Prototyping and development of PLCC packaged ICs
• Repair and field replacement of 32-pin PLCC devices
• Low-current digital and mixed-signal circuits
• Manufacturing processes requiring surface-mount assembly

Key specifications

• Pin count: 32
• Mounting type: Surface-mount (SMT)
• Contact material: Phosphor bronze
• Rated current per contact: 1 A
• Contact type: Spring-contact socket for PLCC packages
• Typical application: Removable IC interface for PCBs

How to use

Place the PLCC socket on the PCB according to the footprint specified by the socket manufacturer, ensuring proper pad alignment and solder paste application for SMT reflow. After soldering the socket to the board, allow the solder to cool and inspect solder joints for continuity and mechanical integrity. Insert the PLCC device by aligning the chip orientation mark with the socket's orientation indicator and press gently until the chip seats into the contacts. For removal, pry the chip evenly from the corners or use an extraction tool to avoid bending leads or stressing the socket contacts.

Usage recommendations

Store unused sockets in anti-static packaging and avoid excessive mechanical force during insertion and removal. Observe the 1 A per-contact current limit and ensure the PCB thermal profile matches SMT soldering guidelines. Periodically inspect contact performance in high-cycle applications to confirm continued low contact resistance and replace the socket if wear or corrosion is observed.
