Son şirket davası hakkında Case Study: Power Supply Maker Boosts Reliability with a Guangdong Potting Compound Factory

Background

A power supply manufacturer needed to improve the reliability of its compact power modules, which combine high voltage, high current, and dense heat in a small package. Early prototypes using a general-purpose resin showed discoloration and hardening over time.

Because the modules were performance-critical, the client needed a partner able to iterate on the formula quickly and prove consistency before committing to volume.

The Challenge

  • High dielectric requirements at elevated voltage
  • Dense heat loads demanding effective thermal paths
  • Thermal cycling that stressed solder joints
  • Need for consistent quality at volume

The rigid material in the prototypes cracked under repeated thermal expansion, and its thermal conductivity was too low to keep hotspot temperatures in check.

The Solution

The client selected a guangdong potting compound factory with in-house RTV-2 formulation. A silicone grade with high dielectric strength and tailored thermal conductivity was applied, with the cure profile adjusted to the client's production line speed.

Parameter Value
Thermal conductivity 2.0 W/m·K
Dielectric strength > 22 kV/mm
Hardness Shore A 50
Operating range -50°C to 200°C

Implementation

The client ran its own accelerated aging and thermal-cycling tests with the new material. Because the factory formulates in-house, formula adjustments were made quickly and communicated directly with the engineers who developed the product, keeping the project on schedule.

Why Silicone Was the Right Choice

Silicone offered the dielectric safety margin and thermal performance the modules required, while its elasticity absorbed thermal expansion that had cracked the previous resin. Its re-workability also gave the client a practical option for handling units during development.

Results

  • Improved dielectric safety margin
  • Better heat dissipation and longer module life
  • Reduced rework through tailored cure and viscosity
  • Batch-to-batch consistency verified against reference data

Long-Term Outcome

The client adopted the material across several product lines and now treats encapsulation as a strategic supply category, reviewing grades with the factory as new, higher-density designs are introduced.

Support and Supply

Beyond the material itself, the factory provided responsive technical support and dependable lead times. That combination of performance and service made the supplier a long-term partner rather than a one-time vendor — which matters for products with multi-year lifecycles and evolving requirements. Repeat orders also confirmed that quality and availability held steady as volumes increased.

Takeaway

Direct factory engagement gave the client faster formula iteration and transparent quality control. Working with a potting compound manufacturer rather than a trader proved decisive for a performance-critical power product.
