Detecting the advantages of in-line LED lamp examination

  There are many kinds of LED lamps in the market, and the brightness and special materials are all different. Today, we have expanded the LED to sort out the merits of this medical LED lamp bead. The LED lamp bead is also a new type of energy-saving light source. Is a type of light source often used in modern home lighting, it is the use of the latest led light-emitting diode technology as a lamp beads, LED lamp bead line because of its relatively strong technical, so the market price is generally more expensive, and some counterfeit lamps Businesses in order to gain the benefits, as much as shoddy line of LED lights filled the lighting market, how can people buy high-quality LED lamp bead it?
 
1. Incoming inspections to prevent suppliers from cutting corners
 
Material quality is the most important factor that affects product performance. However, due to equipment, technology and other conditions, the packaging plant failed to effectively microscopically inspect the raw materials, such as the particle size distribution, morphology, composition of the phosphor; the thickness and composition of the stent plating; the tightness of the silica gel; gold wire Or alloy wire composition and diameter; chip defects. Jinjian's physical examination includes comprehensive micro-inspection of all raw materials in the LED lamp bead, and timely inspection of unqualified raw materials.
 
2. Packaging process inspection, optimization
 
The in-line LED packaging process uses different production equipment. Machine instability, poor tuning parameters will affect the packaging process. Kam Kam detection from the microscopic perspective of the phosphor coating process, wire bonding process and die-bonding process for a comprehensive assessment, give manufacturers timely quality feedback.
 
3. Reduce losses before they occur
 
Once the lamp manufacturer fails to enter the lamp bead due to poor packaging, the credibility of the packaging plant will be reduced, not only the claim disputes, but also the follow-up sales will be affected. The LED microscopic examination can help the packaging factory to better grasp the quality of the in-line lamp beads, prevent them from happening, and reduce maintenance costs.
 
4. Improve the gross margin of products
 
The world's top five LED companies have made in-line LED lamp beads examination as an essential production supporting method to improve product quality. High quality equals high profits! In the face of fierce market competition, domestic LED companies can not only be limited to lower production costs, but also need to improve product quality and have a higher pricing discourse.
 
 
In-line LED lamp beads identification content

Lens process evaluation, type of encapsulated glue, presence or absence of contaminants, bubbles, evaluation of airtightness, heat resistance of glue, coefficient of thermal expansion, glass transition temperature, and chlorine content of the glue.
 
2. Phosphor coating
 
Phosphor layer coating process evaluation, phosphor particle size, particle size distribution, composition, presence or absence of agglomeration and settling.
 
3. Chip:
 
Chip process evaluation, chip pattern micro-structure measurement, defect search, chip contamination identification, presence or absence of electrical leakage, damage, and anti-static capability testing.
 
4. Wire bonding
 
Wire bond bonding process evaluation, one- and two-weld appearance observation, arc height measurement, diameter measurement, lead component identification.
 
5. Solid crystal process
 
Evaluation of solid crystal process, whether there is void in the solid crystal layer, whether it is stratified, the composition of the solid crystal layer, the thickness of the solid crystal layer, and the chlorine content of the glue.
 
6. Bracket
 
Plating process evaluation, defect search, support composition, coating composition, coating thickness, coating roughness, and stent airtightness.
