Could anyone tell me where I can find some literature/standards describing the dimensions and solder land sizes of all common SMD components available in the market? IPC-SM-782 does provides some but not all. Thanks in advance for any response. Rega

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

Lead free solder is bad for the environment, while increasing product costs. The US looked at restricting lead use a few years ago, took no action, and has no plans to enact frivolous legislation like the "greens" have foisted upon the Eurolanders a

Hi, There have been other studies where it was found that lead-free soloder joints are more reliable than tin-lead solder joints irrespective of test conditions. In fact the automotive industry has been using Sn/Ag for underhood applications for a

Japan and Europe are the main champions for the leadfee solder initiative. USA join in due to global political efforts as one of the cub scout leaderships. Military and Automobile industrial-electronics is exempt from the leadfree directive. Reason

I don't think that you would need to test these. Have you ever seen any evidence of solder sticking to them? We use the same material and never notice anything besides flux staying on the bottom. Would the lead absorption if any even be of a concer

We'd expect both OSP poor wetting and improper reflow recipe to show-up in more places than just this one component. But if those are the only choices, we'll go for 'wrong solder paste.' Ooops, that's not one of the choices. Ok, OK, we'll take poo

Steve, I wave solder most if not all our boards with selective wave pallets. I did not catch if the solder balls were on top of the board or on the bottom but that will make a difference on what to do to get rid of them. Pallets are good and bad. On
