OK, you're talking about inline AOI doin' all the work for you, for a price. Fair enough. If you can't afford the inline post-print inspection equipment, though, I still think you can depend on the 2D inspection of the paste to tell you if you've

CAL's word of caution is right on. We tend to stay in the 220C-225C max. temp. on our profiles, and that's because the last heads up from engineering came on a part with a spec. of 230C max. temp. We just found out that one of our old SOIC's is spe

Obviously the less mass in the wave the better. There will be less heat sinking and less push on the solder. Pallet thickness is typically a function of the tallest component on the board. If the board has one component that is tall but small in a

Dear anyone ; Every time that we run profile now ,we will create profile from recommendation of vendor flux and the some critical parameters such as thermal shock or others ... but I don't know that Do you ever create standard profile to be procedure

Adam, After a thorough cleaning, I see most of my customers using a weekly maintenance schedule. However, because the characteristics of the post solder flux will contaminate the wash solution of the stencil cleaner, some customers wait until they a

We do some aperture reductions - but it's not the 10% i'm accustomed to. Looks like it should be more than we currently do (I think we do 10% of length, but no width). Don't think we have a slumping problem, and we're not doing snap-off, only contact

You may have answered your own question. If SSD is the end all save all there would be more people using this technology. I view SSD as an option to have flat planar pads. I also know the price per Board is more then "standard" boards. The sample b

I'm looking for information (links) to pad design and layout spec's for different sized passive SMD's. To be specific, 0603, 0805, 1206 and 3216 sized parts. I'm most interested in finding out about land spacing between two parts. What is accepabl

Sorry to disappoint, bud. Believe it or not, this guy's for real. It'll be sad when his investors find out that returns on contacting are something akin to pass book accounts. I'd do something like the prank that you imply, but this is a lame topi
