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

I went to the SMTNet Career Center and Found 76 pages of jobs available. Are you kidding me? The two hours of my life that does not revolve around electronics can be better spent elsewhere than wading through 76 pages of job postings. On a serious n

On mixed technology PCBs, we find numerous blow holes on the solder joints of radial parts (electrolytics, LEDs, etc). The solution that works so far is to cut the leads very long in the radial inserter so that the part is kinda loose and the air in

I have several carts at my facility, i think we had our machine shop make them a while ago, we can store loaded feeders on the top portion and we can store several screens on the bottom. The idea is to have the days production, if two jobs or more,

It's not so much of a change but a new investment. We have Siplace lines now, and very pleased with the performance. The reason for looking at the Mydata is to remove all the small stuff from the faster lines and reduce changeover times. The idea is

Hi, Can anyone advise what would be the possible cause of having the same short problem at the same spot even after 3 time rework, with a brandnew BGA. I have rework boards with BGA shorts. The problem is most of the shorts boards, will passed afte

Flame retardant epoxy-glass circuit boards are made using brominated epoxies,with the bromine atoms providing the flame retardancy.In a fire,these boards can give off toxic gases.Bromine free epoxies can be used,with other additives being used to pro

There are two places where Laser Soldering is used for rework. One is the low volume, high mix environment where the board value is high. The other is the high volume (regardless of mix) facility where fast process time and quick set-up is required.

Photonic Soldering is useful for several applications in rework where current methods using hot air are inadequate or inefficient. For high-density assemblies, component clearances are limited. In the past, DFM (Design for Manufacturing) specificati

Depending on the stress condition experienced by the solder joints. For joints under a greater stress, the time to reach equilibrium can be shorter. Of course, the change is also more significant in phase structure. For low stress conditions, it may
