Although I am sure that some of the postings here are legitimate, it is obvious that many of them have been written by AOI manufacturers or suppliers. This forum is meant to be a communication channel for process engineers, not salesmen. Please sav

Achieving high reliability and high efficiency in SMT process (Surface Mount Technology) assembly has always been the goal of electronics manufacturers expecting consistency. It depends on the optimization of every detail of the whole process. For SM

Dear Collegs! I would appreciate all responses with opinions about the AOI manufacturers that will be listed below. First of all maybe a short description. In my company we are just starting with the optical inspection of our products. We use screen

Hello all, we use a reflow oven from Rehm in our SMT production. At the moment we solder under nitrogen atmosphere (approx. 500ppm). Now we want to reduce the nitrogen consumption (costs etc.). What consequences can occur here? Especially on the s

Hi All, What 3D/5D solder paste inspection machines are recommended? I've heard the best are CyberOptics and Koh Young - Has anyone used a 'ALeader' SPI machine? Regards

We dodged it for a while but it was inevitable. Here's the question. What do I REALLY need, and does anyone even agree on it? OK, that's *two* questions. The first board we're likely to do has three parts that will need special consideration. One

inspect => conformal coat ... and standards are aligned with that philosophy. I can imagine doing a good job inspecting assembly after being coated with particular coating thickness, optical properties, lighting conditions. Ultra-thins are so thin

| Our first article inspection after machine placement can take several hours depending on the complexity of the board. The operator visually checks the board against the drawing and bill of material. I'd be interested to hear if there are any other

"1/2 of the paste volume is lost from the flux and carriers being removed during the reflow." Don't forget the intersticial space between your solder spheres that you lose during reflow. Not being of an engineering background I couldn't begin to a
