Without knowing your boards and components its difficult to comment- beyond users of those mfgs. and models you mention commenting on performance, reliablity of the equipment and service & support from the mfg. As with any machine, its best to test d

Youch! I know this is going to sound stupid but.... I have done it in the past in limited quantities. We placed capton (polyimide) tape at each of the four corners for a similar situation. It did work but the operator has to be careful in placing

You probably pay the same as me. Ours is just fresher. ;) So fresh, in fact, that sometimes we can smell the brewery, when it's breezin' southerly. Not particularly appetizing, actually, although not as bad as the Stock Pot soup factory. City-wid

Wave Soldering - Icicling/Bridges

Electronics Forum | Fri Jan 24 16:46:21 EST 2003 | MA/NY DDave

Hi, Distance Engineering is always difficult. I am guessing that the old machine and process ran wonderfully / acceptable. If you still have the old machine, how about running an empty board through it and then the new machine. Without flux observ

Wave Soldering - Icicling/Bridges

Electronics Forum | Tue Jan 28 16:27:43 EST 2003 | MikeF

I agree with most of the other suggestions here, but 90 C for a topside preheat temp seems low to me. I remember aiming for 98 to 104 C for topside temp just before hitting the solder. Boards that had large ground/power planes or a lot of layers I wo

Conformal Coating Coverage

Electronics Forum | Thu Jan 30 15:41:52 EST 2003 | MikeF

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get

bulk feeding chips

I don't think it's possible for a turret machine, but I seem to remember some sales guy talking about a camera on his machine that did look at the part before it picked it up. As far as bulk feeding goes, how would you ensure the resistors are right

"Use the pad mating to lead wetting area." If I get your drift, we're talking about the minimum lead area (assuming the pad has an area that's at least as large as the lead) required to be wetted by IPC-610. Hmmmm...that would take some calculation

Hi You are probably right. The only thing I will tell you is that one time as thee DFM engineer working between many electronic designers, component manufacturers and CEMs (contract electronic manufacturers) the component manufacturer would not bud

ESD Safe Flooring Systems

Electronics Forum | Mon Feb 10 20:05:28 EST 2003 | joeherz

Hello, We are looking at new/used buildings and are faced with decisions regarding what type of flooring to have installed. I know a little about epoxy, vinyl tiles, rubber, paint and plain old ESD wax on concrete but don't want to re-invent the wh
