BILLERICA, Mass. -- Bruker Elemental today announces the launch of the all-new Q2 ION™, an ultra-compact spark optical emission spectrometer (OES) for metals analysis. The Q2 ION is a true multi-matrix system for comprehensive incoming material inspection and quality assurance of metal alloys. Its primary applications and metal matrices include copper, aluminum and iron analysis at smaller foundries, inspection companies, metal recycling and metal fabricators.
Results showed SAC, SCN, and mixed assemblies performed similarly in each group. The lowest cycles to fail were observed in groups 1 and 2, followed by groups 3 and 4. Further testing is planned to compare alloys in drop testing where the strain rate and stress levels are much higher.
Thermal cycling was performed with temperature ranges from 0[degrees] to 100[degrees]C, with a dwell time of 10 minutes and ramp rate of 10[degrees]C/s. The test was stopped at 1,686 cycles, when more than 50% failures were observed for each board. Table 1 shows the characteristic life (N63) and early failures (N01) for each case. It can be observed that SAC systems had on average better characteristic life followed by SCN (150 fewer cycles) and mixed (191 fewer cycles) systems. The data favor 238[degrees]C peak temperature, and there was not a significant difference between TAL.Photos/Multimedia Gallery Available: http://www.businesswire.com/cgi-bin/mmg.cgi?eid=6196805&lang=enDIY solar kits are like any other kit, you save money because you save labour costs. The labour is going to be supplied by yourself (and maybe a couple of well meaning friends), so you need to know that you are probably going to take longer to construct your solar panel solutions. Plan for extra time, and if your need is essential, put extra money aside in case you need to hire a professional.A different concern when finding the right kind of DIY solar kit is the amount of components contained within it. You want an all inclusive solar kit. If your kit is missing elements, this will cost you time to purchase the missing element, and time by having to stop or delay construction until the missing item is purchased. The elements of your kit should include: solder, soldering iron, flux, tabbing, solar cells, and instructions for housing your solar panel.Ursula Marquez de Tion is a process and research engineer at Vitronics Soltec, based in the Unovis SMT Lab (vitronics-soltec.com); umarquez@vsww.com.With all this in mind, creating something yourself will definitely boost your ego! So take it slow, find a kit that�s right for you and get started on your energy solutions today!Vibration testing was performed on 12 boards reflowed in air. The goal was to excite the first resonance (bending movement) at relatively low amplitude to induce high cycle fatigue failures. The boards were mounted with standoffs at the four corners to an electrodynamic shaker. Failure data were divided into four groups depending on component location on the board because they experienced different stress levels. Figure 1 shows a schematic of the board with its groups. Two failure modes were observed: pad cratering (groups 1 and 2) and solder fatigue (groups 3 and 4).
