... testing and certification organization. In the beginnings of UL more than 100 years ago stood questions in the range of fire-protection-mechanisms in the foreground. | PCB PLANT | Today all possible products, materials, constructions and systems are tested and evaluated regarding their electrical danger as well as their danger of accident and fire. | PCB PLANT | And in addition there were examined alarm systems and the ability to discover, control and prevent fire. UL develops safety regulations, which are taken over | PCB PLANT | frequently as ANSI standards. Underwriters Laboratories certify and register customers according to ISO 9000. What means this indication for the Microcirtec GmbH and their customers? | PCB PLANT | Products with this indication have international a higher acceptance. Many customers wish or demand a UL marking. The marking offers easements in questions of the | PCB PLANT | product liability and brings a higher acknowledgment at authorities. In order to guarantee the adherence to the examined values, a Follow UP service is ...

... time. We also suggest to put the PCB`s vertically in the stove by using a rack. Good results can be achieved if the assembling | PCB PLANT | process of the PCBs is started immediatedly afterwards. The time after drying should not exceed 48 hours not to rise the risk of delamination again. | PCB PLANT | | FORMING MICROVIAS |. (Demand for small holes is ramping, with CO2 lasers leading the way) Thanks largely to the proliferation of smaller, more complex | PCB PLANT | electronics devices such as cell phones, personal digital assistants, and notebook computers, the PCB industry is experiencing an overwhelming rise in demand for high-density interconnect | PCB PLANT | structures (HDIS). The demand for HDIS translates directly into a vigorous market for the microvias used in many of these multilayer substrates as well as | PCB PLANT | in conventional PCBs. In 1998, for example, the worldwide microvia market made up about four percent of the total multilayer PCB market. By 2007 that | PCB PLANT | market share is expected to expand to nearly 30 percent (Figure 1). ...

... refinement uncomplicated and reliable, but once the manufacturing parameters have been set they can be dependably utilised for further processing and continued use. Due | PCB PLANT | to the thin surface layer – a thickness of 0.15 – 0.3 mµ is recommended – the surface of the pad is smoother and therefore | PCB PLANT | there are, even in fine pitch areas, no restrictions when assembling. The silver functions merely as a protection against oxidation, and the actual solder point | PCB PLANT | is between the copper and chemical tin, therefore the solder point is absolutely stable. It fulfills all UL requirements (UL796 specif.) and meets the usual | PCB PLANT | requirements of automobile manufacturers: Test results Test AlphaSTAR Result Requirement SIR 85°C/85%RH 2.46+9 24h Passed >1E+8; IPC- 4553 IPC-TM-650 2.6.3.5 3.15E+9 96h Passed SIR 35°C/85%RH | PCB PLANT | 100VDC 3.56E+11 24h Passed >1E+10; IPC-4553 and GR 78 (Bellcore) IPC-TM-650 2.6.3.5 4.62E+11 96h passed EM 10V bias, 100V Test 2.46E+9 24h initial Resistance no | PCB PLANT | higher than the Power of 10 ...
