Airing it Out
Thanks to higher soldering temperatures and more aggressive fluxes, fumes from lead-free solders are more harmful than those of tin-lead. What precautions are you taking?
The Remanufacturing Equation
Remanufacturing - restoring products to a like-new condition - is a $50-billion market, and a source of new business for assemblers. A study of three tech products shows a potentially hefty market, at the right discount.

Pb-Free Solder Pots
A Study of Lead-Free Hot Air Leveling
Questions have arisen over copper dissolution into lead-free alloys, particularly the use of alloys that may require added solder pot maintenance. An investigation into controlling lead-free HAL, plus maintaining the pot and separating copper intermetallics.
For NPI, Texas Prototypes Doesn't Mess Around
From a quiet start as an NPI arm of a tier one EMS provider, Texas Prototypes has spun off and branched out, and its band of engineers provides everything from product launch to lifecycle management.

Controlling Pb-Free Processes through AOI
Will AOI prove effective in identifying differences in the appearance of lead-free solder? To wit: does a billboarded chip look the same? What about an insufficient solder joint? A look at how lead-free PCBs impact in-line systems.
Preventing Voids in CSP and BGA Underfill Encapsulants
In a CSP or BGA underfill process, several potential sources of voids exist. Sidestepping voids starts with picking the right material, be it the paste or the underfill.
