I don't get it. The liquidus of 80Pb/20Sn is like 280*C. Your reflow temperature got nowhere near that value. Where did that material go? Is it folded back under the component? Disappeared? Was it ever there? Ask someone while analysis tools to hel

I wouldn't think the vibration from weights dropping would be significant enough to effect the SMT machines. If you are concerned, look into placing vibration dampening pads under the machine feet. you don't need anything fancy, just neoprene pads wo

Manjunath, I prefer orthogonal systems. In my experience they are actually better at detecting coplanarity and HIP defects than multi camera systems. They are obviously limited, in that they can not inspect a component under another component, b

The 740 and 760 basically have the same specs as far as component ranges: 0402-50mm components. The 760 is a bit more accurate and the vision system is better. The 740 was designed when BGA weren't really around and so it can barely vision center b

I want to be clear. You are talking about buying fully populated cards? And not just bare boards. Approach different CM's and compare contracts. You can pretty much get anything from "build from kit" where all the CM does is assembly, to complete s

Manufacturers involved in critical product cleaning may be aware that the U.S. EPA may ban or highly restrict the sales and use of n-propyl bromide in manufacturing. The EPA is interested in the impact on small businesses including costs and performa

| Hey Ya'll! | | Have any of you ever worked with one of V-Tek's "Economax" tape and reel machines? The biggest thing I'm curious about is the type of cover tape that these machines use. It's something they call P.S.A. (Pressure Sensitive Adhesive)c
