SIM card tray Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

The SIM card tray is a precision-engineered, spring-loaded or friction-fit mechanism designed to house and align the SIM card with the device's internal card reader contacts. It ensures proper electrical connection, protects the SIM from physical damage and environmental contaminants, and facilitates easy insertion and removal without tools in modern designs.

Working Principle

The tray operates on a push-to-eject or pull-out mechanism, often using a spring or detent to hold it in place. When inserted, it aligns the SIM card's gold contacts with the reader pins in the phone, establishing a secure electrical interface for data transmission. The tray's design ensures precise positioning to prevent misalignment, which could cause connectivity failures.

Materials

Typically made from engineering plastics (e.g., PBT, PC, or ABS for durability and dimensional stability) or metals (e.g., stainless steel or aluminum alloys for strength and EMI shielding). May include metal springs or clips for retention.

Technical Parameters

Ejection Force 1-3 N (for easy removal)
Insertion Force 0.5-2 N (to ensure secure seating)
Tray Dimensions Varies by phone model (e.g., ~12mm x 9mm x 1mm for Nano-SIM)
SIM Size Support Nano-SIM, Micro-SIM, eSIM (embedded)
Durability Cycles ≥10,000 insertion/removal cycles
Operating Temperature -20°C to 85°C

Standards

ISO/IEC 7810, ETSI TS 102 221, DIN EN 62684
