Automotive reliability primarily comes in two aspects: lifespan and environmental resistance. The former refers to the fact that normal running can be guaranteed within a lifespan while the latter refers to the fact that PCB functions remain unchanged when environment changed. ,sport betting huawei app gallery


online casino game malaysia, The average automobile lifespan in 1990s is in the range from 8-10 years and the present range from 10-12 years, which means that both automotive electronic system and PCB should fall within this range.


In the process of application, automobiles should withstand climate change, from extremely cold winter to hot summer, from sunlight to rain, and environment change owing to temperature rising as a result of their own running. Put it differently, automotive electronic system and PCB have to withstand multiple environmental challenges including temperature, humidity, rain, sour fog, vibration, electromagnetic interference and current surge. Additionally, since PCBs are assembled inside automobile, it is mainly influenced by temperature and humidity. ,5 ringgit

Light weight and miniature of automobiles is beneficial to energy saving. Light weight derives from weight reduction of each component. For example, some metal parts are replaced by engineering plastic parts. Moreover, both automotive electronic equipment and PCB should be miniature. For example, the volume of ECU (Electronic Control Unit) applied in automobiles was approximately 1200cm3 at the beginning of 2000 while that is less than 300cm3, decreasing by four times. Plus, starting point firearm has transformed from mechanical firearm connected by wires to electronic firearm connected through flexible wires and with PCB inside, decreasing by more than 10 times in terms of volume and weight.


lvic winner, Light weight and miniature of PCB derive from density increasing, area shrinking, thinness and multiple layers.

Automobiles combine machinery and electronic equipment. Modern automobile technology integrates traditional technique and advancing scientific technology, such as manual inner decorating parts and advancing GPS. In modern automobiles, there is electronic equipment with different functions at different positions and different functions derive from different types of PCBs. ,4D bonus


paypal roulette, According to substrate materials, automotive PCBs can be classified into two main categories: inorganic ceramic-based PCB and organic resin-based PCB. Ceramic-based PCB features high temperature resistance and excellent size stability, making it directly applied in motor system with high temperature. However, it features bad ceramic manufacturability and high cost. At present, with the development of resin substrate material in terms of its heat resistance capability, resin-based PCB has been widely applied in automobiles with substrate material with different performances applied in different positions.


Generally speaking, Flexible PCBs and Rigid PCBs are applied in normal gauges indicating vehicle speed and mileage and air conditioner equipment. Double-layer or multi-layer PCBs and Flex PCBs are used in audio and video entertainment equipment inside automobiles. For communication and wireless positioning equipment and security control equipment, multi-layer PCBs, HDI printed circuit boards and Flex PCBs are applied. When it comes to automotive motor control system and power transmission control system, special boards should be applied such as metal-base PCBs and Flex-rigid PCBs. For automobile miniature, component-embedded PCBs are applied. For example, micro processor chip is applied in power controller, directly embedded in power controller PCB. For another example, component-embedded PCB is also used in navigation equipment and stereo imaging equipment of automatic backing system.

resurt4d, Because automotive PCBs stay in multiple environments, including rainy day or humid environment, it's quite necessary to implement THB test for them. The test condition includes the following elements: temperature (85°C), humidity (85%RH) and bias (DC 24V, 50V, 250V or 500V).


THB test has to consider CAF migration of PCBs. CAF usually takes place between adjacent vias, via and line, adjacent lines or adjacent layers, leading to insulation reduction or even short circuit. Corresponding insulation resistance depends on distance between vias, lines and layers. ,no deposit free credit casino malaysia 2019

Automotive collision-resistance/predictive braking safety system plays a role as a military radar device. Since automotive PCBs are responsible for transmitting microwave high-frequency signals, substrate with low dielectric loss needs to be applied with the ordinary substrate material to be PTFE. Different from FR4 material, PTFE or similar high-frequency substrate materials require special drilling speed and feeding speed during drilling.

Automotive electronics brings more heat energy owing to high density and power and hybrid power and electromotives tend to require more advancing electric power transmission system and more electronic functions, which leads to more requirements on heat dissipation and large current. ,32 red roulette


It's relatively easy to fabricate thick copper double-layer PCBs while it's much more difficult to fabricate thick copper multi-layer PCBs. The key point lies in thick copper image etching and thickness vacant filling. ,yahoo games free


Inner routes of thick copper multi-layer PCB are all thick copper and therefore and graphic transfer photo-induced dry film is also relatively thick, requiring extremely tremendous etch resistance. Thick copper graphic etching time will be long and etching equipment and technical condition in the best state so as to ensure complete routings of thick copper. When it comes to external thick copper routing manufacturing, combination can be first applied between copper foil with relatively thick lamination and graphic plating thick copper layer and then comes film voidance etching. Anti-plating dry film of graphic plating is relatively thick as well. ,yahoo games free


Surface difference is relatively large between inner conductor of thick copper multi-layer PCB and insulating substrate material and ordinary multi-layer board lamination fails to totally fill resin with cavity generated. In order to solve this problem, thin prepreg with a high content of resin should be applied as much as possible. Copper thickness of inner routings on some multi-layer PCBs is ununiform and different prepregs can be applied in areas with a large thick copper difference or a small difference. ,world cup 2018 kits
