First, the cause of LED yellowing:
1. The baking temperature is too high or the time is too long;
2, the proportion of the glue is wrong, A glue is more likely to yellow.
solve:
1. AB glue is cured and demolded in 120-140 degrees / 30 minutes, and it is easy to yellow when it is baked for more than 150 degrees;
2, AB glue curing at 120-130 degrees / 30-40 minutes, more than 150 degrees or long time baking will yellow;
3. When making a large lamp holder, reduce the curing temperature.
Second, LED bubble problem:
1. Bubbles in the bowl: poor support of the bracket;
2. Bracket bubble: the curing temperature is too high, and the epoxy curing is too intense;
3. Cracking rubber, bursting top: curing time is short, epoxy resin curing is not complete or uneven. AB glue exceeds the usable time;
4. Bubble on the surface of the lamp cap: Epoxy adhesive has difficulty in defoaming or the user uses insufficient vacuum, and the glue dispensing time is too long;
Solution: Improve process or contact epoxy supplier depending on usage.
Third, LED bracket climbing reasons:
1. The surface of the bracket is uneven and produces capillary phenomenon;
2. AB glue contains volatile materials;
Solution: Please contact the supplier.
Fourth, the LED package is short-baked after the mold is baked.
1. The stacking in the oven is too dense and the ventilation is poor;
2. The local temperature of the oven is too high;
3. There are other color pollutants in the oven.
solve:
Improve ventilation, remove stains, and confirm the actual temperature in the oven.
5. The lamps on the same row of brackets have some coloring or gelling time, and the quality is uneven. Cause: The stirring is not enough: fully stir evenly, especially at the corners of the container.
Sixth, the reason is not easy to demould: AB glue has problems or the glue does not reach the curing hardness.
Solution: Please contact the supplier to confirm the curing temperature and time.
Seven, add the same batch of the same dose of colorant, but the color of the product is not the same reason: the concentration of the toner is not uniform; or the toner precipitates.
Solution: Warm up the toner and mix well before using.
Nowadays, the function and appearance of mobile phones are similar, but the charging interface is not unified. The Android camp has Micro USB and Type-C ports, while the iPhone camp has Lightning. Different charging ports use different charging cables, which is very unfriendly for users who often need to use multiple phones. To solve this awkward situation, the three-in-one data cable was born. What is the three-in-one data cable? Three-in-one data cable means that one data cable includes Micro Usb Cable, USB Cable For Iphone and Usb Cable Type C. So one data cable can be used by all mobile phones.
Three-in-one data line is also known as multifunctional data cable. In the original data cable, the combination scheme is added, and the combination PCB is configured, which can support a variety of equipment and avoid the trouble of frequently looking for data line. It combines Lightning, a 30-pin port, and a Micro USB port, and is compatible with multiple devices. It can connect to any smartphone or tablet, including iPhone, iPad, Samsung, etc.
From the technical point of view, the three-in-one data cable does have a strong advantage. With continuous development and improvement, three in one data cable products in the original data cable appearance with woven cloth, will also add a light color on the three in one data cable, so that the data cable function is stronger and more exquisite, more and more people accept and buy. In the era of big data,the 3 In 1 Usb Cable can be said to have deeply affected our work and life. We believe that with the technical development of 3-in-1 mobile phone data cable, it will bring us more convenient transmission experience.
