​Precise Light Distribution, Reliable Enablement: TENSAN High‑Reliability Materials Safeguard the Foundation of Mini LED Displays

In the field of high‑end displays, Mini LED is driving a comprehensive evolution of visual experiences with its ultra‑high brightness, extreme contrast, and vivid colors. The key to achieving this experience lies in enabling tens of thousands of Mini LED chips to emit light stably, durably, and uniformly – and this ultimately depends on a crucial category of invisible materials: high‑reliability solders.

TENSAN (Shenzhen Tianzhongshan Industrial Co., Ltd.), as a high‑tech enterprise in the electronic materials field, provides market‑validated high‑reliability packaging material solutions for Mini LED. Our product portfolio includes fine‑pitch printing solder paste and more, fully supporting a wide range of applications such as large‑format display screens, outdoor commercial digital signage, automotive center‑stack displays, instrument clusters, electronic rearview mirrors, and in‑vehicle entertainment systems.

TENSAN Mini LED Solutions:

TS506 Low‑Silver Low‑Void No‑Clean Solder Paste

TENSAN TS506 is a no‑clean, halogen‑free solder paste specifically designed for SMT assembly processes. It employs a Sn98.5Ag1.0Cu0.5 low‑silver alloy system with a melting range of 221°C–227°C, and Type 4 powder (20–38μm) supports fine‑pitch printing down to 0.25mm (10 mil). In Mini LED chip packaging, TS506 demonstrates the following core advantages:

• Excellent fine‑pitch printing performance: Stable rheological properties ensure consistent and clear solder paste deposits on fine‑pitch pads, meeting the stringent printing accuracy requirements of high‑density Mini LED packaging.
• Ultra‑low void rate: The proprietary flux system enables controlled outgassing during reflow, effectively reducing gas entrapment within solder joints, ensuring that void rates on large thermal pads consistently remain below 15%, thereby safeguarding the heat dissipation efficiency and long‑term reliability of Mini LED chips.
• High‑reliability electrical performance: Halogen content is below 500ppm (L0 grade), and the product passes copper mirror corrosion testing as well as SIR testing (at 40°C/90% RH and 80°C/85% RH), ensuring that electrochemical migration does not occur even under harsh humid conditions, guaranteeing the long‑term stability of Mini LED modules.

Why Choose TENSAN TS506?

A mature reliability solution is the cornerstone of product quality and stability. From automotive displays to outdoor large screens, from mobile devices to AI terminals, TENSAN continues to empower the visual future with innovative technology. The low‑silver alloy design of TS506 reduces material costs by approximately 30–40% compared to conventional SAC305 while maintaining excellent soldering performance, offering a choice that combines performance and cost advantages for the mass production of Mini LEDs.

We are always committed to making every screen shine clearly, stably, and durably through solid R&D and professional products.
