VSTAR Transparent LED Film Production Process Full Details - Professional Manufacturer in Shenzhen

Описание: As a professional transparent display manufacturer, VSTAR (Shenzhen Factory) adheres to precision craftsmanship and strict quality control to produce high-quality transparent LED film. Each step from raw material to delivery integrates core technology, ensuring excellent light transmittance, stable luminous performance and durability. Below is a concise breakdown of VSTAR’s complete production process.

I. Core Production Process

1. Film Selection & Pretreatment

The film is the core substrate of transparent LED film. VSTAR selects flexible transparent substrates with over 90% light transmittance, featuring temperature resistance, aging resistance and bending resistance. After incoming inspection, substrates undergo dust removal, antistatic treatment and surface activation to ensure a clean, flat surface for subsequent processes.

2. Precision Solder Paste Printing

Solder paste printing guarantees circuit conductivity. VSTAR adopts high-precision stencil printing, adjusting paste thickness and range per circuit design to avoid missing printing, bridging or false printing. High-adaptability solder paste enhances welding firmness, reducing cold soldering and desoldering risks.

3. SMT Mounting

Surface Mount Technology (SMT) enables miniaturization. VSTAR uses automatic high-speed placement machines with visual positioning, achieving micron-level placement of driver-integrated LED chips. Chip spacing error is controlled within ±0.1mm, with real-time precision monitoring to prevent offset or damage.

4. Reflow Soldering

Semi-finished products enter multi-zone temperature-controlled reflow ovens. Precise temperature curves (preheating, constant temperature, reflow, cooling) ensure solder paste melts fully, forming firm joints. This avoids high-temperature damage to films/chips and eliminates bubble/crack issues, boosting product reliability.

5. Initial Aging Test

To eliminate early failures, semi-finished products undergo 72-hour continuous lighting under rated conditions. We monitor luminous stability, brightness uniformity and circuit status, detecting and repairing cold soldering, chip necrosis or short circuits in advance.

6. Vacuum Potting Encapsulation

Vacuum potting with high-transparent rigid resin ensures even coverage of chips/circuits, no bubbles or impurities. Cured adhesive balances protection (waterproof, dustproof, impact-resistant) and light transmittance, avoiding refraction distortion.

7. Secondary Aging Test

Post-potting, products undergo 72-hour lighting plus high-low temperature/humidity cycling tests. We verify sealing, luminous stability and structural firmness, ensuring stable performance in diverse scenarios with no color deviation or faults.

8. Finished Product Inspection & Delivery

Qualified products pass light transmittance, brightness calibration, appearance, dimension and electrical tests. They are antistatic-packed with manuals and inspection reports. Custom packaging is available for safe delivery.
