We are looking into what equipment would be necessary assemble circuit boards. We will most likely purchase a circuit board and use a pick and place machine to populate the board, and then send through a reflow oven. Then inspect the boards and ass

Calculate numbers according to your situation, as follows: Cost = Cost per kilowatt hour x [Amps x volts x hours of operation � 1000] Cost per kilowatt hour: What we need to do to figure out the total cost is get out our electric bill. Look on the

Process, process, process. We have been doing BGA's, uBGA's, LCC's etc for over 10 years. We have no X-ray and we don't even have a real rework station. In 2005 we placed just under 100,000 BGA's we reworked less than 100, we scrapped less than 30. W

Does anyone use or have any simple wave/reflow oven exhaust monitors with a visual check (LED). I was going to design something crude resembling a fan with an electric winding (electric motor of sorts)and a load (resistor maybe with a transistor if

Hey guys, My company is currently looking into developing a SMT line. I have an interesting perspective on this due to the fact that I worked a SMT line for quite a few years as an equipment operator. Now I am an engineer and at a different company

I have been working on the SMT area for a while now, must of my experience is on programming and pick and place, now in my new job I have to control a complete SMT line and I have a little knowledge on working with solder paste but I like to read mor

I would not recommend doing BGA soldering with only a hot air gun. I have done it in the past, but the boards would eventually come back from the field because the solder joints did not form correctly and the BGA would have to be reworked again. I

Type K thermocouples are the most commonly used in the electronics industry. There are various types of thermocouple types that can be used. Examples include [Ray Prasad]: • Type K ¾ nickel-chromium vs. nickel-aluminum (most commonly used); tempera

I will, though I have to admit that the process thus far has been about as pleasant as getting a tooth pulled. I still wish - as the topic of my thread implied - that there was more information available on production and assembly equipment in the fi

I'm just getting into temperature profiling our PCB's. We recently bought a new reflow oven. The company purchased a mole before I was hired. This is what I will be using. What is the preferred way to attach the thermocouples to the PCB locations of
