Reasons of LED lamps are getting darker

Why LED lamps are getting darker www.seamarkxray.com The LED light source module is generally composed of a substrate, a chip, a packaging material, a lens, etc. In daily use, the long-time operation of the LED easily causes the LED to become darker and darker, and even the light fails. For this problem, D.L. Barton has done research experiments. There are some reasons for the failure of the LED light source module. Generally, the following are the main points: LED lamps are getting darker reasons: 1.The packaging material is degraded; Under long-term work, the LED will cause the temperature of the LED to rise, resulting in a large decrease in the optical transparency of many polymers in the LED exterior packaging material (such as epoxy resin), resulting in a decrease in the light-emitting efficiency of the LED; The study found that when the LED temperature reaches 95 degrees and the current is greater than 40 mA, the LED package material will be carbonized; 2.Dur...

Solder paste printing defects and solutions in SMT chip processing process

Solder paste printing defects and solutions in SMT chip processing process www.seamarkxray.com    sales25@zhuomao.com.cn +8618779975930 In the SMT chip processing process, solder paste printing is very complicated, and it has very important significance for product quality. This article mainly discusses the common defects of solder paste printing. 1. Incomplete printing: The solder paste has insufficient viscosity and cannot be effectively attached to the PCB or the blade is worn; Solutions: ①Replace the solder paste. When selecting the solder paste, the size of the solid metal particulates should be considered, and the particle size should be smaller than the opening size of the steel mesh; ②Regularly check and replace the scraper; 2. Solder skip, Non-wetting/false soldering: insufficient solder paste or unqualified PCB, easy to appear Solder skip, Non-wetting/false soldering; Solutions: ①Choosing a well-known manufacturer of PCB board brands can reduce t...

Increase ICT test coverage -Bead probe Technology

Increase ICT test coverage -Bead probe Technology www.seamarkxray.com Original:  PCB assembly increase ICT test coverage Bead probe technology is an exclusive patent application by Agilent (Keysight Technologies). Using existing wiring to increase ICT (In-Circuit-Test) test point coverage without additional board space, to increase printing. Test points on the board to achieve assembly ICT testing can be used for ICT testing purposes. he density of the parts on the board is getting denser and denser, but the space is getting smaller and smaller, especially the board of the mobile phone. The first thing to be sacrificed is the test point that does not have any function. Many bosses think: “Quality is manufactured, As long as the quality of the board assembly is completed, there is no need for subsequent electrical testing. Which engineer can guarantee that the product does not have a bug? The assembly plant also cannot guarantee that they have zero defects in assembling the...

SMT BGA solder ball inspection method- Know about cost

图片
Original: SMT BGA solder ball inspection method - Know about cost Usually, when we check the soldering status of BGA solder balls, we can usually check them with  X-ray inspection machine  If we want to check if the solder balls lack solder or cracks/weld bridge/short defects. BGA solder ball inspection Basically ,There are three ways to check the solderability of BGA, using X-rays, Red Dye Penetration Test and slicing. Before you want to analyze the welding status of the BGA, it is recommended that you use  X-ray machine  to see if you can see any problems. The other two methods continue to be used only when X-Ray is unable to determine the problem. There is also a way to use optical instruments to inspect BGA solder balls, such as microscopes or fiber optic miniature cameras, but since the BGA spacing is getting smaller, it usually only checks the two rows of BGAs. Tin ball, another is a bit difficult, so we won’t introduce it here. In fact, there is als...
