LED lamp bead inspection is the detection and analysis of the microstructure of the LED lamp bead material and production process. With the comprehensive micro-check of the lamp bead, the packaging manufacturer can find out the material defects and process hazards in the production stage of the lamp bead, and improve the product quality inspection efficiency; from the conventional "customer complaints - failure analysis - lamp bead improvement" mode Converted to "Discover hidden dangers - lamp bead improvement" mode.
Jinjian LED quality experts suggest that the LED lamp bead microscopic examination should be included in one of the regular lamp quality inspection items. Through monthly periodic inspections of each batch, LED packaging manufacturers can better grasp the quality performance of the products, ensure the quality of the lamp beads consistently, and make full use of this quality control means to declare the LED packaging factory to the lamps. Focus on the quality of the beads and improve the core competitiveness of the products.
Service customer: LED packaging factory
Most packaging manufacturers do not purchase professional microstructure inspection equipment due to the investment return ratio, and lack of professional technicians in the material discipline. As a supporting service provider in the LED packaging industry, Jinjian Testing focuses on the microstructural inspection of materials to compensate for the lack of equipment and technology of packaging manufacturers. By providing accurate, fast and cost-effective testing services, the packaging factory can help find the material defects and process hazards of the lamp beads in the production stage, and improve the reliability and cost performance of the LED products.
Jinjian detection LED lamp bead body inspection advantages
â— Incoming material inspection to prevent suppliers from cutting corners
Material quality is the most important factor affecting product performance. However, due to equipment, technology and other conditions, the packaging factory failed to effectively microscopically detect the raw materials, such as the particle size distribution, morphology, composition of the phosphor; the thickness and composition of the stent coating; silicone gas tightness; gold wire Or the composition and diameter of the alloy wire; chip defects. The medical examination content of Jinjian detection includes comprehensive microscopic inspection of all raw materials in the LED lamp bead, and timely inspection of unqualified raw materials.
â— Packaging process inspection and optimization
The LED packaging process uses different production equipment. Unstable machine and poor tuning parameters will affect the packaging process. Jinjian detection comprehensively evaluates the phosphor coating process, wire bonding process and solid crystal process from a microscopic point of view, giving the manufacturer timely quality feedback.
â— Reduce losses and prevent problems before they happen
Once the lamp manufacturer fails due to poor packaging, the reputation of the packaging factory will be reduced, not only the claims dispute, but also the subsequent sales work will be affected. LED microscopic examination can help the packaging factory to better master the quality of the lamp bead, prevent it from happening and reduce maintenance costs.
â— Increase the gross profit margin of the product
The world's top five LED companies have taken LED lamp bead inspection as an essential production supporting means to improve product quality. High quality is equal to high profit! In the face of fierce market competition, domestic LED companies cannot be limited to reducing production costs, but also need to improve product quality and have higher pricing power.
â— Know yourself and know each other
Physical examination can not only analyze the advantages and disadvantages of its own products, but also check competitor products, make structural comparisons, know ourselves and know each other.
â— Third-party evaluation report to improve the quality control credibility
The use of solid materials, product-free, and well-engineered third-party evaluation report content, bring confidence to the lighting plant's procurement responsible person, increase the chances of the lighting factory to place orders.
Jinjian tests the key raw materials and each process of the lamp beads, gives a score, and issues an appraisal report in time.

As we all known a common health risk that miners face is thermal – or heat – stress. Mining environments are often very hot and humid, overexposure to heat and humidity can cause the body to become fatigued and distressed.
Win 3 Portable Heat Stress Monitor is designed to quickly and accurately evaluate potential heat stress environments. It can be attached on the cap lamp cable or put in the pocket or even hang it some where. Thanks to its continuous temperature&relative humidity measuring, it will real time help workers to remove themselves from the overexposure enviroment.
