What you have run up against is the unfortunate consequence of the transition period from Sn-Pb to Pb-free. In the past 2-3 years there have been several studies highlighting the differences in reliability between mixed metal systems, Sn/Pb, and SAC

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

In addition to reducing oxides my understanding is that nitrogen increases the surface tension of solder (I've also read the inverse). Bottom line, Nitrogen reduces rework, improves quality, improves solder appearance, and reduces maintenance. Shea

Hi, There has been a lot of disputes in our company about changing present HASL to another Finishing which can provide more flatter pad surface in fine pitch applications. ( perhaps Ni/Au, OSP ) The target is to reduce solder defects, thus improve

As you know 90% of defects come from the printer. This product is well worth the investment. You will improve yeilds and reduce rework. Very important with micro BGA's. Also lead free components do not self center (during reflow) as well. There is ve

Reels are 100% the best, vibration feeders should always be a back up, they are quite unreliable through no fault of their own. Say you have 1000 parts to be placed, and the cost of a reel is 100$ more than a tube, but the reel loads 10 to 1 over th

Well assuming that the parts are genuinely damaged when rejected and you want to rework them to reduce scrap,you could use a shadow graph and get the mechanical spec on clear film.Then rework accordingly you should be able to rework most leads.

Sam, Like I said, AOI for pre-reflow inspections is the easiest to program and maintain. Each vendor of AOI has its pluses and minuses for programming and performance. Do a careful investigation of each vendor to learn about their machine performanc
