In the highly competitive semiconductor industry, although carriers (magazines) may seem like a minor component in the chip packaging and testing process, they actually bear the critical responsibility of ensuring chip quality and enhancing production efficiency. As a formidable player in the industry, DOHONE has developed the remarkable D2PAK carrier through masterful craftsmanship and exceptional innovation capabilities.

The creation of DOHONE's D2PAK carrier originated from a deep collaboration with STMicroelectronics (Shenzhen), a global leader in semiconductor technology. Renowned worldwide for its cutting-edge R&D, stringent quality control, and substantial market share, STMicroelectronics has long maintained a top position in the semiconductor packaging and testing sector. Given its prestigious status and high-end operations, the company imposes extremely rigorous quality requirements on carriers — these essential production support tools.

DOHONE's D2PAK carrier employs an advanced integrated molding process. Compared to traditional assembly methods, this approach not only reduces component count and minimizes risks from loose connections or gaps but also significantly enhances the carrier's structural integrity. During mold manufacturing:

High-grade mold steel is selected

Precision processes like electrical discharge machining (EDM) and ultra-fine grinding ensure mold accuracy exceeding industry standards

Critical parameters — extrusion pressure, temperature, and timing — are strictly controlled to guarantee flawless demolding and dimensional tolerances within ±0.02mm

Post-molding, the carrier undergoes:

Precision cutting

CNC machining (surface flatness ≤5μm)

Anodized surface treatment (25μm thickness, Ra<0.4μm)

100% automated optical inspection (AOI)

Vacuum-sealed packaging

Through this rigorous scientific process, DOHONE successfully customized D2PAK carriers meeting STMicroelectronics' exacting specifications, delivering the order on schedule with premium quality. This professional efficiency and product excellence earned DOHONE STMicroelectronics' strong endorsement. Subsequently, STMicroelectronics deployed these D2PAK carriers across its manufacturing facilities in Malaysia and Morocco, while also recommending other DOHONE handling tools to its global supply chain partners.

This expansion not only validates DOHONE's product quality but also certifies its capability in cross-regional collaboration under global supply chain frameworks, further solidifying DOHONE's leadership in semiconductor carrier manufacturing.

Transportation method

We discuss with our customers the best shipping method to help customers save costs. Generally, we use air freight or international express delivery for small batch order products in overseas markets, and large batch order products in sea freight.
