Product introduction

    Manufactured from high-quality Permalloy sheets and fabricated through high-precision progressive stamping and precision bending processes, our miniature components feature compact dimensions and well-defined structural edges. Designed for high-tech electronic fields requiring compact space layouts, accurate positioning, and cost-effective mass assembly, they provide efficient localized magnetic shielding while offering excellent installation convenience.

Core Features:

1. Miniaturized Precision Forming
Leveraging high-precision progressive stamping dies and bending equipment, we can manufacture micro-bending parts with intricate geometries and compact dimensions. We strictly guarantee the bending angle accuracy and positioning tolerances of mounting holes/slots for U-shapes, L-shapes, and various irregular structures, ensuring perfect fit within the confined spaces of PCBs or micro-modules.

2. Structural Stability & Easy Assembly
Through carefully designed bending structures (such as the positioning slots, locking tabs, and mounting holes seen in the images), the parts not only possess sufficient structural rigidity but also facilitate quick plug-in, snap-fit locking, or spot-welding/screw assembly. This significantly simplifies the assembly process for our clients' end products and effectively boosts mass production efficiency.

3. Uniform & Stable Magnetic Shielding Performance
Manufactured from high-nickel (approx. 80%) Permalloy material and subjected to strict stress-relief treatment after stamping and bending, our parts effectively eliminate internal stresses caused by cold working. This ensures that the material maintains excellent initial permeability (μi) even in its miniature form, precisely absorbing and diverting localized stray magnetic fields to provide reliable magnetic protection for adjacent sensitive electronic components.

4. Clean & Consistent Surface Condition
The products undergo precise deburring, cleaning, and passivation/anti-corrosion treatments. The edges are smooth and free of burrs, with a uniform natural metallic finish (or optional surface plating based on requirements). This eliminates the risk of electrical short circuits caused by burr detachment and meets the cleanliness standards for high-precision electronic assembly.

Primary Applications:

• SMT/PCB On-Board Shielding: Used as on-board localized magnetic shielding covers for high-precision A/D converters, weak signal amplification circuits, and sensor chips, directly snapped or soldered onto circuit boards.
  

  
  

• Micro-Sensor Packaging: Acts as internal shielding brackets for Hall effect sensors, magnetoresistive sensors, or micro-current transformers, ensuring      detection accuracy remains unaffected by external weak magnetic field  interference.
  

  
  

• Connectors & RF Terminals: Serves as shielding outer covers or locking clips for precision electronic connectors or high-frequency signal terminals to prevent electromagnetic crosstalk.
  

  
  

• Medical Implants & High-End Consumer Electronics: Applied in micro-medical devices such as pacemakers and hearing aids, or as magnetic shielding partitions within premium smartphones and smartwatches.
