Historias de Solder

The widely used solder paste brands in China include both internationally renowned brands and excellent local manufacturers.The following is a classification of common brands and their characteristics:

Gold embrittlement is a soldering defect that refers to solder joints that contain too much intermetallic compound (IMC), resulting in increased brittleness and reduced reliability.

With the development of surface assembly technology in the direction of high density and small size, traditional reflow welding process may cause damage to heat-sensitive devices, so a process that can heat welding devices in a specific area is needed. Laser welding is a new welding process, the technology can be local non-contact heating and heating time is very short, can quickly form a reliable solder joint. However, there is still a disturbing phenomenon in the process of laser welding, that is, the random burning of thermal elements around the solder joint. This situation is mainly caused by the laser reflection (LR) of the pad and the ball during the laser jet welding ball bonding process. Therefore, it is necessary to understand the relationship between laser reflectivity and solder.

Its about these men from an elite force of military officers that have to go to Iraq to fight and help Iraq with ISIS after they left they got there 9 hours later. They needed back up so called for air support and they send a chopper called black hawk and when it go to Iraq it got shot down by ISIS military..

Solder leakage is an important part of electronic manufacturing, and its quality directly affects the subsequent soldering effect and product reliability.As a common problem in the solder paste printing process, solder leakage not only reduces the soldering quality of the product, but also may lead to the failure of the whole product.The following is a brief discussion of the solder leakage phenomenon in the solder paste printing process:

To effectively reduce the cost of using solder paste, you can start from the following aspects:

Flip-chip interconnection technology has been widely used in high-performance and consumer electronics. High-performance packaging has achieved steady development, realizing the interconnection with more than 10,000 I/Os and a pitch of less than 200um, realizing the transition from ceramic substrates to low-cost organic substrates, and achieving the popularization of lead-free solder pastes. The transition to organic substrates has prompted low-temperature solder pastes to replace high-temperature solder pastes.

With the advent of the "post-Moore era", heterogeneous integration based on small chips will become the mainstream of semiconductor packaging. Small chips tend to be packaged in 3D directions to achieve flexible modular integration and system-on-chip integration. It should be considered that 3D packaging will bring some problems. For example, high-power electronic components often dissipate large amounts of heat during use, which requires a high melting point solder to maintain the thermal stability of the interconnect. However, the interconnection of some heat-sensitive components requires low-temperature solder. Some of these substrates have high heat sensitivity and cannot withstand high temperatures and prolonged heating in reflow ovens. Laser soldering can be used as an alternative soldering process due to its localized and non-contact heating, rapid temperature changes, and no need for flux.
