Dear Sirs, My name is Evgheni Moscov, I'm production technologist of ADD-TECHNOLOGY SRL (www.addgrup.com), Kishinev, Republic of Moldova, Eastern Europe. Our profile is design, development, production, implementation and technical support of hardware and software for automated meter reading systems for energy resources consumption, made on the basis of advanced communication means utilization. We often use SMD components, like BAV99LT1G, BC807-40LT1G and BC817-40LT1G. We are developing a new device and plan to solder this type of components on solder wave machine. Solder wave temperature is 265-270 0С(deg. C). The board is double-sided mounted, to reduce the complexity of the PCB mounting, we’d like to solder THT and SMD components simultaneously on wave solder machine. In this regard appears some questions: • Since you are manufacturer of this components, what is your opinion about such way of soldering? • Are this components suitable for wave soldering? • This temperature, won't it affect the performance of the SMD components? • Isn't this temperature critical? won't it cause the breakdown of the component? Our task, is to understand, are this components suitable for wave soldering or only for reflow. We are waiting for your comments, the question is very actual, please give us the answer ASAP. 1731 2013-02-22 12:51:59.525

Hi! Could you suggest any solutions for isolated DC / DC converter to power electromagnetic flowmeter sensor? 2238 2011-08-01 04:22:45.0
I am currently designing a water meter and am looking for a low-power micro-controller with an accuracy of +/- 3%. Can you direct me to a good supplier that offers parts that will work with your components? 2342 2011-07-21 19:09:35.0
My company produces electricity meter, and we are interested in development of power line communication modem with Spread-Frequency Shift Keying (S-FSK) modulation (in accordance with IEC 61334-5-1). On your internet site you offer PLC modem that contains AMIS49587 processor and NCS5650 power line driver. In some of your presentations you refer to High Speed Robust S-FSK with AMIS49588, but we can't find data sheet for that. Do you have some solution for PLC modem with this type of modulation, where the power consumption is not larger then 6W? 1970 2011-06-15 17:53:07.0
