Hi Rob, I must take issue with your statement �By definition, no clean solder can be not-cleaned�. All no-clean fluxes can be cleaned. Whether or not one cleans no-clean depends on a variety of factors. More than eighty percent of all post reflow

Hi Paul M, There are no silly questions but silly answers.. and here is maybe a few if I understand you correctly: If you consider place anything less than a 1.27mm (50mil) pitch component down or a chip less than a 1210, hey it maybe don't even work

Hey SWAG- Not an uncommon scenario where I'm at. But the bottom line is, as others have said: Profile, profile, profile. Here, we have dedicated profile boards for each product we build and in most cases they're EXACT representations (my library i

Hello Before I say anything. Here is one caveat, I work for a 3D paste inspection vendor, I will not mention which. So you can take whatever I say with a grain of salt. Paste inspection will make a difference if you want to put the effort into it ma

Allow me a contrary viewpoint. I've had these things on my floor and had customers get outsourced evaluations done with them. Most expensive boat anchors I've run across. First the good points: The automated scanning and pattern recognition is go

I think you're getting steered in the wrong direction, with the exception of DaveF's link. By the way, I'm a PCB fabricator, just to avoid any backlash. IPC 4101 is the IPC guideline for raw materials. It has 6 slash sheets for lead-free capable
