Novel Approaches for Minimizing Pad Cratering

With the electronic industry moving towards lead-free assembly,traditional SnPb-compatible laminates need to be replaced with lead-free compatible laminates that can withstand the higher reflow .. read more

Testing Printed Circuit Boards for Creep Corrosion in Flowers of Sulfur Chamber

The iNEMI technical subcommittee on creep corrosion is developing a flowers-of-sulfur (FOS) based qualification test for creep corrosion on printed-circuit boards (PCBs). The test setup consist .. read more

Testing Intermetallic Fragility on Enig upon Addition of Limitless Cu

As reliability requirements increase,especially for defense and aerospace applications,the need to characterize components used in electronic assembly also increases. OEM and EMS companies look .. read more

Elemental Compositions of Over Two Dozen Cell Phones

Twenty-nine different cells phones have been disassembled,ground up,dissolved and analyzed for elemental content,mainly for information about the metals present in the phones,but also for some .. read more

Effects of Tin and Copper Nanotexturization on Tin Whisker Formation

The physical mechanisms behind tin whisker formation in pure tin (Sn) films continue to elude the microelectronics industry. Despite modest advances in whisker mitigation techniques (i.e.,barri .. read more

Leaching of Lead and Other Elements from Portable Electronics,Part II

Portable electronic device circuit packs were ground up to more than meet EPA sieving criteria and were then subjected to the well known EPA Method 1311 leaching protocol. Based on work from th .. read more

The Property Research and Applications of Vertical Pulse Copper Plating

Horizontal and vertical pulse plating have been widely used for panel plating in PCB industry,but rarely used for pattern plating. This article analyzes and reviews the crystal structure,throwi .. read more

NEMI Cost Analysis: Optical Versus Copper Backplanes

The outlook for optical PCBs is unclear for mainly three reasons: 1) today's limits for copper boards can be stretched with design and manufacturing improvements,2) the market demand for next g .. read more

Formation and Growth of Intermetallics at the Interface between Lead-free Solders and Copper Substrates

Intermetallic formation and growth were studied for the alloys Sn-3.2Ag-0.8Cu,Sn-3.5Ag,Sn-0.7Cu,and Sn-9Zn. Coupons of solder joints (prepared by melting some of each solder alloy on a copper-p .. read more
